13->'''Amalia:''' The situation requires I accept such help as I find. Though it be from thieves. I shall accompany you until we find my companions. No longer.\
14'''Balthier:''' Let's think of her as a 'Guest', then. Unlike Fran or myself, our 'Guest' probably won't be taking orders from anyone anytime soon. And she'll leave when she pleases. So, we keep to our affairs, and she to hers.

16
17This is a character who joins the PlayerParty only temporarily. If this happens early in the game, they'll be [[ATasteOfPower much more powerful than you]]. If you're lucky, maybe you can unequip a DiscOneNuke from them. But if you buy them equipment, beware of SoLongAndThanksForAllTheGear! Sometimes, this is averted with StuckItems applied to all their equipment.
18
19If you see them again, [[TemporaryPartyMemberToVillain it will probably be as an enemy]]; however, if they join your party again, they will seem [[RedemptionDemotion a heck of a lot weaker]]. Unfortunately, what removes them from your party may well be [[SacrificialLion them getting killed after you've gotten used to having them around]].
20
21Despite there being little incentive to keep this character in your party for gaming reasons (lack of weapons sold for them, etc.) it's popular in gaming fandom to force these characters back into your party via cheat codes or VideoGame/GameShark.
22
23Compare with CrutchCharacter, OptionalPartyMember, EleventhHourRanger, and AwesomeButTemporary. Contrast AndNowForSomeoneCompletelyDifferent, where an existing party member takes over as the viewpoint character temporarily. Don't confuse with GuestFighter. May often also be a HeroOfAnotherStory.

26!!Video Game Examples:
27[[foldercontrol]]
28
29[[folder:Action Adventure]]
30* In ''VideoGame/CaveStory'', Curly accompanies you like an AttackDrone throughout Labyrinth M. [[spoiler:If you save her life and restore her memory, she will rejoin you in Sacred Ground.]]
31* [[spoiler:Yomiel]] in ''VideoGame/GhostTrick'' for [[spoiler:one very special mission and one single trick]]. [[spoiler:Missile]] joins you a few occasions as well.
32* Plenty throughout ''Franchise/TheLegendOfZelda'' series:
33** ''VideoGame/TheLegendOfZeldaALinkToThePast'' has Zelda early in the game (you have to break Zelda out of prison and escape from Hyrule Castle with her during the opening sequence), a monkey for one of the early dungeons and a maiden in one of the later dungeons. [[spoiler:She's a demon and the dungeon boss]]. Even later, you can find a treasure chest in a house that will inexplicably start following Link around.
34** ''VideoGame/TheLegendOfZeldaLinksAwakening'' has Bow-Wow, a ghost, Marin, and the Flying Rooster. Bow-Wow and the rooster are actually useful, Marin gives you some fun scenes, and the ghost... is just a BrokenBridge character that you have to get rid of to get into the next dungeon.
35** ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' has Princess Ruto with you for the whole third dungeon. You also briefly get [[spoiler:Princess Zelda]] with you during the final dungeon, as you both escape it.
36** ''VideoGame/TheLegendOfZeldaMajorasMask'' allows you to take control of Kafei in the final part of his lengthy sidequest, and is used to move blocks onto switches while Link battles enemies.
37** ''VideoGame/TheLegendOfZeldaOracleGames'':
38*** There are three pets. You can get one to join you permanently, while the others will only appear in the quests in which they're introduced in each game.
39*** In ''Oracle of Seasons'', at one point you can take Rosa with you as part of a "date", and along the way you can ask her to open locked doors with her special key. You cannot take her out of Subrosia, however.
40** ''VideoGame/TheLegendOfZeldaTheWindWaker'' has Medli and Makar, who are actually playable for one dungeon each. If a Platform/GameBoyAdvance is connected to the [[Platform/NintendoGameCube GameCube]] while you play, Tingle can join in too anytime. Lastly, though not playable, [[spoiler:Princess Zelda helps Link during the final battle against Ganondorf]].
41** ''VideoGame/TheLegendOfZeldaPhantomHourglass'' has a young Goron that Link briefly joins forces with to overcome parts of a dungeon and the first half of the boss battle. The player controls one at a time and needs to switch between them as needed. The Goron can fight and destroy boulders, but obviously doesn't have the same arsenal of items as Link does.
42** ''VideoGame/TheLegendOfZeldaSpiritTracks'' has a Phantom [[spoiler:possessed by Princess Zelda's spirit]]. Like earlier examples, you switch between Link and the Phantom.
43** ''VideoGame/TheLegendOfZeldaSkywardSword'' has [[spoiler:Groose]], who helps you during the second and third Imprisoned fights.
44** ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' has the girl who you help escape from the Thieves' Hideout, as a ShoutOut to the girl from ''A Link to the Past''. [[spoiler:This time around she ''isn't'' the boss]].
45** ''VideoGame/TheLegendOfZeldaBreathOfTheWild'': Using the Link and Midna amiibo from ''Twilight Princess'' will let Wolf Link accompany you. In a more traditional sense, Link is accompanied by differing companions when challenging the Divine Beasts -- [[WarriorPrince Sidon]] against Vah Ruta, [[ActionDad Teba]] against Vah Medoh, [[AChildShallLeadThem Riju]] against Vah Naboris, and [[LovableCoward Yunobo]] against Vah Rudania.
46** ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'':
47*** With the exception of Teba, all characters who helped Link access the Divine Beasts in ''Breath of the Wild'' (Yunobo, Sidon, Riju) reprise their roles as Link's temporary sidekicks while he's conquering the Temples and helps them become Sages (in the case of the Wind Temple, Tulin inherits the role of his father). Afterwards, Link establishes a bond with said characters, allowing him to summon avatars based on them during normal gameplay.
48*** Inverted with the raids on monster camps. The extermination groups aim to defeat all monsters who installed said camps across Hyrule, and Link can offer himself as an extra member to help them.
49* ''VideoGame/{{Okami}}'': This happens twice during the sixth dungeon (Wawku Shrine). When you fight Lechku, you'll be helped by [[spoiler:Shiranui, the past incarnation of Amaterasu]]. When you fight Lechku again (who is now helped by Nechku), your extra companion will be Oki. Likely because of the need of a second character in both battles, these two Owl monsters are absent during the BossRush of the final dungeon (Ark of Yamato), since you can only refight bosses alone there.
50* ''VideoGame/StarControlII'':
51** The Spathi can be recruited as allies by doing an optional quest. However they all leave after only a couple months. Fortunately, you do get to keep any Spathi ships you happened to build during that time.
52** If you impress the Thraddash by repeatedly destroying their ships, they happily ally with the person now demonstrably more powerful than them. However, they're holding a PlotCoupon within their sphere of influence which is necessary to complete the game, and they refuse to willingly share it. Whether you betray them by stealing it or [[VideoGameCrueltyPotential let the Kohr-Ah Death March take them out]], their alliance will no longer be available afterwards.
53[[/folder]]
54
55[[folder:Action Game]]
56* ''VideoGame/Bayonetta2'' has allies join Bayonetta and fight with her on the side in different points through the game. The one who fights with her the most often is Loki, who is also the only one with limited health. Other people who tag along with her include Rodin (who is able to oneshot any enemy in his way), [[spoiler:Bayonetta's mother Rosa in the Vigrid chapters, and the Masked Lumen/Balder in the final chapter]].
57* ''TabletopGame/ForgottenRealms''-based video game ''VideoGame/DemonStone'' has a chapter where you are required to exchange control of the sorcerer Ilius for special guest star [[Literature/TheLegendOfDrizzt Drizzt do'Urden]], the dual-wielding drow ranger who ''defines'' melee badassery for many ''D&D'' players. Combined with a nerfing of weapon enhancements, a single-target super attack instead of a multi-target super, enemies that regenerate, and a few segments that even remove the ability to swap into control of your other characters in preference for just Drizzt, playing the super-badass drow just plain sucks.
58* In the GBA/DS adaptation of ''Film/RevengeOfTheSith'', whichever Jedi is not the main protagonist is temporarily controllable during the fight with Count Dooku as an inverted DualBoss.
59* ''[[VideoGame/SoulSeries SoulCalibur 3]]'''s adventure mode features many characters coming and going in your party. They should in theory start out stronger than characters you always have available, however due to leveling up by fighting (even if you lose) it makes more sense to just keep using your own characters.
60[[/folder]]
61
62[[folder:Fighting Game]]
63* During the final route of ''VideoGame/DuelSaviorDestiny'' you gain access to many different units you've fought with or against before, including gamebreakingly powerful units like Muriel Sheerfield, who more or less operates as a super version of your caster unit Lily.
64* ''VideoGame/MortalKombat9'' has The Director, who appears in several Challenge Tower missions, and is also playable in one despite not being playable anywhere else in the game.
65[[/folder]]
66
67[[folder:First-Person Shooter]]
68* ''[[VideoGame/Area51FPS Blacksite: Area 51]]'': [[spoiler:the BigBad actually fights as a member of your squad for several missions (against his own troops!), as part of a BatmanGambit to get inside the Allied HQ.]] However, despite being an augmented super-soldier (who can soak a few hundred bullets in the final battle), when he's on your side he's physically indistinguishable from your other AI-controlled squad buddies.
69* In the PC version of ''VideoGame/GhostReconAdvancedWarfighter'', the ''President of the United States'' himself carries a pistol and follows you around (very briefly) after you rescue him from rebel soldiers.
70* At one point in ''VideoGame/JediKnightIIJediOutcast'', Luke Skywalker himself fights alongside you.
71* In ''VideoGame/JediKnightJediAcademy'', you're joined by Kyle Katarn in one of the levels.
72* In the finale of The Passing in ''VideoGame/Left4Dead2'', Zoey, Francis, and Louis assist your team by sniping at zombies from a balcony and tossing you items in between waves of hordes. They're also ignored by the zombies so you don't have to worry about protecting them.
73* ''VideoGame/PerfectDark'' has Jonathan in one mission and Elvis in three others.
74[[/folder]]
75
76[[folder:MMORPG]]
77* ''VideoGame/FinalFantasyXIV'' does it a lot for certain story and class quest encounters, including one in ''Heavensward'' which basically revisits an older dungeon with two significant [=NPCs=] replacing the usual player party. It can also occur in some other places, though usually in a lesser role or more of a EscortMission situation.
78* ''VideoGame/GuildWars'':
79** The game has henchmen who are implied to be working alongside the various players and heroes. None of the heroes "leave" per se, but there are some henchmen who do not follow you to later areas. Most of the time, they are available for the first couple of missions then when you get to the main dungeons and missions, stay behind. A few do decide to not stay behind, or actually go ahead and join in different areas. And most of the characters in the ''Guild Wars'' universe don't make the cut to ''Eye of the North'', despite being in your party when you take the quest that begins the main Eye of the North questlines.
80** Some quests have you amass a bunch of support characters who actually can fight very well, while others {{Leeroy|Jenkins}} or are noncombat.
81** With a few exceptions, the central five (Mhenlo, Eve, Cynn, Devona, Aiden) will always be available. But the biggest exception is in Factions where Mhenlo is a non-henchman NPC who has to be protected at all costs.
82** Kormir fits this trope to a T, acting as a CrutchCharacter of a sort before losing her sight and [[spoiler:Becoming the Goddess of Truth in the final battle.]]
83* This is a recurring theme in ''Franchise/ShinMegamiTensei''.
84** In both the first and second game, you can get Cerberus as a mini-DiscOneNuke (it avoids the level restriction too), although you lose them soon after they've had their use; later you can get them back permanently.
85** ''Shin Megami Tensei IMAGINE Online'': Early on in the game, you complete a quest to heal your former mentor's wounded Cerberus. The Cerberus accompanies you for the next few acts, and can be summoned like a normal demon. However, it suffers from the "Wounded" attribute, slowing it's growth. At the end of Act 3, Snakeman takes Cerberus away to continue his treatment. You can later obtain a fully healed Cerberus as a gift from Snakeman after reaching level 30.
86* ''VideoGame/StarWarsTheOldRepublic'': In the ''Fallen Empire'' expansion and beyond, there have been a handful of these. Darth Marr at the start of the expansion and Darth Acina in one chapter of ''Eternal Throne,'' and (if you choose to [[spoiler:spare his mother, Senya, who pleads for his life]]), a subversion with [[spoiler:Arcann]], who shows up as one of these early on and becomes a full-blown Companion option later.
87* ''VideoGame/WorldOfWarcraft'':
88** The game has many EscortMission quests where the NPC can actually fend for himself pretty well. The Wrath expansion also introduced several group quests where the player can call [=NPCs=] to help him if there aren't enough other players around to help with them. There is also a quest to free captive horde soldiers that will join forces with the rescuer for a while as thanks.
89** {{Lampshade|Hanging}}d in quests involving Creator/{{Harrison|Ford}} [[Franchise/IndianaJones Jones]] which states that you are either being escorted by him, or are supposed to simply stay out of the way while he does his thing.
90** In the War of the Ancients and Hour of Twilight dungeons released at the end of Cataclysm, you were joined by Illidan and Tyrande, and Thrall, respectively, that would act as a 6th party member giving the group buffs and attacking mobs and bosses with you.
91** Similarly used in a few places in Mists of Pandaria, mostly in lore-heavy Scenarios where they're the focus of the story, and a few fights in raids (like Galakrond in Siege of Orgrimmar.)
92[[/folder]]
93
94[[folder:Party Games]]
95* ''VideoGame/MarioParty9'': The Ruins Rumble minigame gives the Rivals team three Dry Bones allies that the one player must defeat in addition to the player characters themselves in order to win. Even if the one player is successful in eliminating all of their opponents, they can still lose if any of the Dry Bones survive to the end of the minigame.
96* ''VideoGame/MarioParty10'': If Keep-Away Mayhem is played in a game with only three players, a computer-controlled Shy Guy will take the place of the third member of the Rivals team.
97[[/folder]]
98
99[[folder:Platformers]]
100* An unusual platformer example is the second and third games in the ''VideoGame/JakAndDaxter'' series, where some characters will fight alongside the duo. Sometimes, it's also an escort mission, but sometimes it's a full battle. With the exceptions of The Kid [[spoiler:and Damas]], these guests will have a HP bar on the top-left of the screen; if they lose all their health, it's game over. Most of the time, you often get one or two guests, but at one point, you get '''three'''. The party members include Sig, Ashelin, Jinx, Mog, Grim, Samos (old and young), Torn, and [[spoiler:Damas]].
101* ''Franchise/RatchetAndClank'' also has characters who serve as guest star party members in several games.
102** [[VideoGame/RatchetAndClank2002 The first game]] ([[VideoGame/RatchetAndClank2016 and its re-imagining]]) has the Sergeant (Cora in the re-imagining) and the Pokitaru Resort Manager, both as [[EscortMission escort characters]].
103** [[VideoGame/RatchetAndClankUpYourArsenal The third game]] introduces guest stars who combat alongside you; in this case, the [[LovableCoward Galactic Rangers]]. Captain Qwark, Skrunch, and Skidd also join in the escort variation.
104** ''[[VideoGame/RatchetAndClankFutureToolsOfDestruction Tools of Destruction]]'' introduces Talwyn Apogee, Cronk, and Zephyr as guest stars. They will all fight alongside you in several battles.
105** Talwyn even serves as a party member in ''Quest for Booty'', alongside [[spoiler:Rusty Pete and Captain Slag's head]] in an escort mission.
106** ''[[VideoGame/RatchetAndClankFutureACrackInTime A Crack in Time]]'' also introduces a guest star in Alister Azimuth, who fights alongside Ratchet in several missions [[spoiler:until his FaceHeelTurn after defeating Cassiopeia]]. Captain Qwark will fight alongside you in several missions, and so does a group of Fongoids. A Vulcan will serve as an escort character early on.
107** Starting with ''VideoGame/RatchetAndClankAll4One'', Clank will sometimes become a full party member instead of functioning as a helipack.
108** In the non-canon game ''[[VideoGame/RatchetAndClankSizeMatters Size Matters]]'', the first mission has a little girl ([[spoiler:really a ''Pinocchio''-like spy who's TheDragon to [[BigBad Otto Destruct]]]]) follow you around while you defeat random enemies.
109* This is a common occurrence in the ''VideoGame/SlyCooper'' games.
110** Starting from [[VideoGame/Sly2BandOfThieves the second game]], there will be certain missions where Sly, Bentley and Murray will work together, with one being playable, and the other two being party members. There are also two missions in which you follow Constable Neyla around as she directs Sly to a point he can access- though it turns out she’s really intending to betray him the first moment she gets; the third time you have to follow her, it's a chase sequence.
111** ''VideoGame/Sly3HonorAmongThieves'' has the Guru, the Panda King, Penelope, and Dimitri, who were only controllable during certain missions. Similarly, certain missions have you controlling [[BigBadEnsemble Carmelita Fox]], who's not even part of the gang (rather, [[KnightTemplar she's]] one of the [[RivalTurnedEvil main antagonists]]).
112** In ''VideoGame/SlyCooperThievesInTime'', Sly's various ancestors (Rioichi, Tennessee "Kid", "Bob", Sir Galleth, and Salim) are playable in their respective eras. [[spoiler:At the end of the game, they all reappear for the final stage to regain their stolen canes and, in Tennessee's case, save Sly Cooper and Carmelita Fox from Le Paradox]].
113* ''Franchise/SuperMarioBros'': Unlike in ''VideoGame/SuperMarioWorld'' (where Yoshi can accompany Mario and Luigi in as many levels as possible except Castles, Fortresses and Ghost Houses), the famed green dinosaur is relegated to this status in ''VideoGame/SuperMarioSunshine'', ''VideoGame/SuperMarioGalaxy2'' and the ''VideoGame/NewSuperMarioBros'' sub-series; in all those games, as soon as the current level having Yoshi is cleared, the characters will leave him behind. It's not possible to continue forward with him.
114[[/folder]]
115
116[[folder:Real Time Strategy]]
117* ''VideoGame/Pikmin2'' features the Bulbmin, who are immune to all environmental hazards but can only be used in the dungeon they are found in.
118* ''VideoGame/StarcraftI'':
119** Edmund Duke starts as an enemy, but after you rescue his downed ship from the Zerg swarm surrounding him, he joins the rebel cause and you even get to control him in battle two missions later, before you leave the rebels He appears also in the prequel ''Loomings'' campaign, which was part of the Starcraft demo and could be downloaded and put in the custom maps. Furthermore, he should have been featured in a cut mission too, along with Tassadar.
120** Jim Raynor is one of the main characters of the Terran campaign. He makes a comeback for a couple of missions at the end of the Protoss campaign with his ship, the ''Hyperion'', helping you against the Zerg, and an entire Terran base with the full tech tree unlocked in the final level. You won't be able to control him again in the expansion ''Brood War'', although he will appear frequently in cutscenes and briefings.
121** In ''Brood War'', Kerrigan also makes an appearance in the fourth mission of the Protoss campaign as a controllable charater. She won't even be a playable character in the Zerg campaign despite being the dedicated protagonist.
122** Fenix, who was one of the main charaters of the original Protoss campaign, only makes a very short scripted appearance in a cutscene of the ''Brood War'' Protoss campaign, only to join your forces for a mission in the Zerg campaign.
123* ''VideoGame/WarcraftIII'': The campaigns have a few examples.
124** In the Human campaign of ''Reign of Chaos'', Jaina joins for a few levels before leaving. In later parts of the campaign, Muradin joins up, but halfway through the final level [[spoiler:he takes an ice shard to the head, and [[DisneyDeath seemingly dies]].]] You end the campaign with only Arthas.
125** In the Orc campaign, [[LeeroyJenkins Grom Hellscream]] is playable for two levels. During the second level, [[spoiler:he decides to drink Mannoroth's demonic blood to get power to deal with Cenarius. And while it works, it also corrupts him, turning him into an antagonist for the rest of the campaign.]]
126** In the Night Elf campaign, Illidan is playable for a grand total of one level.
127** In the Sentinel campaign in ''The Frozen Throne'', Tyrande is only playble for a few levels, [[spoiler:before she collapses the bridge she was standing on to cut off the undead. The player has to bail her out of encirclement in the final level]]. Additionally, [[spoiler:the main character, Maiev, actually walks out on Malfurion in disgust once he decides to work with Illidan to save Tyrande, and is not playable for the final level]]. For a more minor examples, Naisha the Huntress is around for three levels before [[spoiler:getting crushed underneath the collapsing Tomb of Sargeras]], while the Paladin hero the player rescues in one of the later levels is playable for that level only, and does not stick around afterwards.
128** In the Blood Elf campaign, if the player succesfully finishes the secret TowerDefense level, they get a generic Brewmaster hero for the following level only.
129** In the Undead campaign, both Kel'Thuzad and Garithos are only playable for one level each. Kel'Thuzad simply moves out of focus, while Garithos [[spoiler:gets YouHaveOutlivedYourUsefulness from Sylvanas, and ends up slaughtered by undead.]]
130** In the ''The Founding of Durotar'' bonus campaign, the player gets several heroes who come and go:
131*** Nazgrel helps the party investigate a suddenly silent outpost, which ends up with the first encounter with Kul'Tiras forces. Notably, he is not a hero, instead being a stronger version of Wolf Raider unit.
132*** Drek'Thar helps the team in the quest related to the exodus of thunderlizards from their natural habitat. Turns out that Kul'Tiras navy has made their base there and drove the lizards out.
133*** Samuro helps the party in distracing another Kul'Tiras base, alowing Rexxar and others to infiltrate Theramore.
134*** Jaina joins shortly afterwards, when Rexxar finds said base burned to the ground by Naga. She leaves after Rexxar and co. enter Theramore.
135*** Baine Bloodhoof briefly helps you after you rescue him from the harpies, for a limited definition of "helps" since he is significantly lower level and can't carry items.
136[[/folder]]
137
138[[folder:Roguelike]]
139* ''VideoGame/AbsentedAgeSquarebound'':
140** In the Warehouse Driftworld, [[spoiler:Yayoi and Hoop will temporarily join as ally units during the final third of the dungeon. However, they end up getting separated near the end and won't show up again in reruns of the dungeon. They will also help in the FinalBoss fight by summoning obstacles for Karen to use against the boss.]]
141** The Parking Lot Depths and the Arcade Mode exclusive Nameless Tower allow Karen to use Summonstones to either summon an ally as a separate unit or have the ally temporarily replace Karen as the controllable character. The Parking Lot only has Scale as an ally while the Nameless Tower has Iris and Astrake.
142* In ''VideoGame/PokemonMysteryDungeonExplorers of Time[=/=]Darkness'', you are joined on a mid-game dungeon run by [[spoiler:Grovyle]], who is a huge asset to your team as you can simply stand back and let him do the fighting to conserve strength. And later, you are joined by a [[spoiler:''Shiny Celebi'' of all things, [[CuteBruiser who deals out more ass-kickery than you ever thought possible from a pink fairy thing.]]]]
143** [[spoiler:Hydreigon]] in ''VideoGame/PokemonMysteryDungeonGatesToInfinity'', who shows up after you're [[spoiler:separated from your partner]]. He's likely to be around 30 levels higher then you and can effortlessly plow through the enemies you encounter (Save for the few that can confuse him). Predictably, he doesn't stick around for very long. [[spoiler:He officially joins the team in the post-story at his original level of 64, and is still likely be stronger then anyone else on the team for a very long time.]]
144** Almost all of the dungeons in the latter half of ''VideoGame/PokemonSuperMysteryDungeon'' have you accompanied by at least one Pokemon from the Expedition Society who'll most likely be several levels higher then you and your partner. However, the game's difficulty is high enough compared to the previous entries that you'll likely find yourself needing to rely heavily on their assistance to survive, and despite them technically being on the same team as you, you're not actually able to freely bring them on missions until you've totally completed the story.
145[[/folder]]
146
147[[folder:Role-Playing Game]]
148* ''VideoGame/{{Absinthia}}'': Ruthea is temporarily playable during Freya's flashback, the Typh Village quest, and [[spoiler:Lilith's final phase]].
149* In ''VideoGame/ArcRiseFantasia'', the fourth party slot is often reserved for a guest character. In [[spoiler:the first part, you get '''a lot'''. Rastan in Jada, Cecille near Diamant, Adele in Olquinia, (until she turns batshit on L'Arc), Serge in Olquinia AND Ebur Ruins, Leslie starting in Antrax, and crazy batshit Adele in Ebur Ruins]].
150** There's even a section of the game where you temporarily play as [[spoiler:[[VillainShoes the bad guys]]. [[RuleOfThree including batshit Adele.]]]]
151** Another point to make is that you get two characters with a hefty amount of control of before they're brushed aside by the plot: Alf and [[spoiler:Niko]]. Alf gets better stats and Excel Acts than L'Arc, only to be outdone by his ability to summon Simmah the Rogress. [[spoiler:That is, until he is [[TheReveal revealed to also be a Child of Eesa and can summon Rogress too,]] and goes out his way to fight against his brother's kingdom]]. [[spoiler:Niko]] on the other hand [[spoiler:is a coward and is absent in several boss fights near the later part of the game before he ultimately quits traveling with the team.]]
152* The last two missions of ''VisualNovel/AseliaTheEternalTheSpiritOfEternitySword'' are built around Yuuto getting a powerup along with his girlfriend. However, Lesteena has no combat ability whatsoever. So instead, you get to use the white spirit Io, who has some pretty powerful abilities.
153* ''VideoGame/AstraHunterZosma'': When fighting ship enemies, the player controls Captain Scuttlebone's ship, the Silver Blossom, making Scuttlebone the closest thing the game has to a playable boss. Once Scuttlebone stops accompanying the party, the ship battles become unavailable.
154* A whole party of these appear in the tutorial of ''VideoGame/BaldursGate'', and leave as soon as it's done. Xan and Branwen do the same in ''VideoGame/BaldursGateII'', with [[spoiler:Yoshimo]] being a more straight storyline example.
155** Imoen was initially supposed to be one, accompanying you only during Chapter 1 and then die afterwards for plot reasons. Complaining testers led the developers to reinstate her as a fully recruitable party member.
156** The semi-official mod ''Ascension'' for ''Throne of Bhaal'' allows to potentially recruit [[spoiler:Balthasar]] for the final battle, even as a controllable ally without joining the party like other members.
157** [[spoiler:Caelar Argent]] can be one in ''Siege of Dragonspear'' for the final battle.
158* In the penultimate arc of ''VideoGame/BoxxyQuestTheGatheringStorm'', the party travels back in time to the First Internet, and a [[MyNameIsQuestionMarks nameless]] warrior joins them while they climb [[EvilTowerOfOminousness The Spire]]. The twist is that [[spoiler:he’s actually Boxxyfan, the main villain from the first game, and we’re witnessing the events that led up to his StartOfDarkness.]] Needless to say, he leaves at the end of the chapter. [[spoiler:(Although you do get him back for the TrueFinalBoss).]]
159* In the prologue to ''VideoGame/BravelySecond'', Yew's lifelong friends Janne and Nikolai join him on his quest to save Agnès. While their equipment is customizable, they don't gain experience points like Yew, which is a pretty obvious tip-off that they won't stick around for too long. Later on, at the end of the yokai sidequest, [[spoiler:Ringabel]] joins you for the boss fight. He is not directly controlled by the player, instead functioning as an AssistCharacter by periodically attacking the boss.
160* Teepo in ''VideoGame/BreathOfFireIII'' leaves the party near the beginning of the game, whereupon everything he has on him is subject to SoLongAndThanksForAllTheGear. Luckily, skills he learnt from enemies beforehand are transferred to the skill note list instead.
161* ''VideoGame/BrownDustII'':
162** Lathel and Justia encounter unlikely allies in the various Story Packs who can assist them in dealing with the warlock threat of the normal scenario by joining them as temporary party members. They can later join them for real through the gacha system or by signing valuable mercenary contracts in the pubs of their respective Story Packs.
163** The Character Packs possess a similar premise, though in this case, the entire party is temporary and cannot be switched out with regular members until the normal story is cleared.
164* ''VideoGame/BugFables'':
165** Maki accompanies the party for the first half of Chapter 5 and through part of Chapter 7, [[spoiler:and during the "Confidential" post-game quest]]. As TheAce of the Explorer's Association, his attack deals much more damage to enemies than the party's regular attacks and ignore defenses, but he cannot be controlled and instead attacks automatically.
166** Through the Forsaken Lands, [[spoiler:Queen Elizant II travels with the party. She does not directly attack like Maki does, but while she's around, it's possible to call her for a stat buff. She also assists the party during the fights with the Dead Lander group and the first wave of the flaming Roach Constructs.]]
167** Mun, an orchid mantis kid, accompanies the party during the quest "Help Me Get It Back!", of which he's the quest-giver. Much like Maki, he automatically attacks enemies, but his assistance, however, is very ineffective, as his kicks deal only 1 point of damage, and he cannot pierce defenses, which makes him unable to inflict the damage even to enemies with 1 point of defense (which is the majority of enemies encountered during the quest, so the best hope he has is when the enemy he attacks is frozen or has the defense-decreasing status ailment).
168** Madeleine assists the party during her second quest, "Butler Missing Again!". She is also the non-controllable automatic attacker, and she provides assistance by slapping the enemies twice with her {{parasol|OfPain}}, for 2 points of damage per slap.
169** [[spoiler:In the post-game quest "Loose Ends", the Ant Lieutenant assists the party during the battle with the Mothfly horde. She also cannot be controlled and attacks automatically, with her spear attacks inflicting 3 points of damage.[[note]]However, since they don't ignore defenses, and the Mothflies have permanent defense boost during the fight, she inflicts 1 damage point less than she's supposed to.[[/note]]]]
170* ''VideoGame/CrescentPrism'': Astrid temporarily joins the party when fighting Chroma Gunner, but acts automatically. In Chroma Tower, [[spoiler:she has a scripted automatic battle with Count Chroma, where they exchange blows before Astrid seemingly sacrifices herself to defeat him]].
171* In the web-based ''VideoGame/CrystalStory'' series, Reuben and Phoebe, both party members in the first game, come back in the second game for some plot points like when Lina is [[spoiler:kidnapped]]: Reuben fills her slot. Phoebe drags the protagonist into a sidequest after a temporary party split.
172* ''VideoGame/{{Deltarune}}'':
173** In Chapter 1, Susie joins your party early game before leaving again to act as a semi-antagonist. During this time, she will only ever attack in battle, and the player has no say in what she does. She eventually joins the party for real, however, and then the player can control Susie in battle.
174** In Chapter 2, Noelle joins Kris for a segment in the middle of the game where Ralsei and Susie are unavailable. She's fully controllable in battle and [[spoiler:is the catalyst for the "Weird" route]], but she's not available for the later parts of the game.
175* ''VideoGame/DiabloIII'' does this with all your companions before you have the option of having them join you for real. Other {{NPC}}s also join you from time to time, such as Leah, [[spoiler:Adria]] and [[spoiler:Tyrael]].
176* ''VideoGame/DigimonStoryCyberSleuth'' features a bunch of guest star party members - from allies to even enemies - though the likelyhood that they're useful is extremely rare, often dealing ScratchDamage and becoming invincible dummies the enemy can wail on forever. If they can use support skills, though, they're pretty good. [[ArtificialStupidity If they heal the wrong team members, it's frustrating.]]
177* ''VideoGame/DigimonStoryCyberSleuthHackersMemory'': The number of guest star party members increases exponentially during Domination Battles and Turf Wars, allowing Keisuke to call upon previous and new characters [[GameplayAndStoryIntegration as long as the story allows so.]]
178* In the ''Franchise/DragonAge'' series:
179** In ''VideoGame/DragonAgeOrigins'', the Warden has a partner or two during their origin story, before they start to meet their actual [[RagtagBunchOfMisfits party-to-be]]: Ser Gilmore and [[ActionMom Eleanor]] for the Human Noble, Mouse, Jowan, and Lily for the Mage, Soris for the City Elf, Tamlen and later Merrill for the Dalish Elf, Leske for the Dwarven Commoner, and Gorim for the Dwarven Noble. It's not even over once they reach Ostagar: there's [[SacrificialLamb Daveth and Ser Jory]], your fellow Warden recruits, and then finally a pair of anonymous {{Redshirt}}s made available for the run up the Tower of Ishal (or just one, if you're the Human Noble Warden and thus have the dog as a party member).
180** ''VideoGame/DragonAgeOriginsAwakening'' gives you another one in the form of [[spoiler:Mhairi, who gets disposed of in a {{Player Punch}}ing manner]]. [[spoiler:Mhairi]] actually has an approval meter, will level up at least once during the level, and even gets what appears to be a set up for personal mission; making [[spoiler:her]] death more surprising and tragic.
181** ''VideoGame/DragonAgeII'' has Carver and Bethany, though which one sticks around longer depends on Hawke's class (if Hawke's a Warrior/Rogue, Carver is killed, while Bethany dies if Hawke's a Mage). The surviving sibling will either die or be PutOnABus by the end of the first act depending on your actions (though they'll return for [=DLC=] and the final act if still alive). The ''Mark of the Assassin'' DLC has Tallis, who's only around for that story.
182* ''VideoGame/DragonQuest'':
183** ''VideoGame/DragonQuestIV'':
184*** There are several guest characters following you that are AI controlled in battles. Some can even be met after their respective departures
185*** If you meet with Healie in the cave below the Strathbaile forest, he'll gladly come along with Ragnar and serve as his healer during the first chapter.
186*** Oojam joins Meena and Maya's party in Chapter 4, with this being the only time he's in the party.
187*** In the fifth chapter, Hank Hoffman fills in as a fourth party member until you land up in Mintos, where he seems to find his true calling.
188** ''VideoGame/DragonQuestV'' has Prince Harry. There's also your father and Honey assisting you in a few battles in the early half of the game. Bianca can technically be a guest member if you decide to [[spoiler:marry Nera or Debora instead.]]
189** Utterly broken in ''VideoGame/DragonQuestVII'', where you periodically get guest party members for a dungeon or two, often including the boss of that dungeon. While you can't control the guest, they have literally infinite HP and MP, and often an infinite number of healing items- and the boss is just as likely to waste a turn attacking the guest as he is the player characters.
190** Subverted in ''VideoGame/DragonQuestVIII'', in which your party is briefly joined by the contemptuous and utterly incapable Prince Charmles during fights with Argon lizards (evidently just enough to give him some marginal legitimate claim over the prize). He inflicts 1 point of damage (if he's lucky and doesn't miss), and then flees.
191* ''Franchise/TheElderScrolls'':
192** The series in general has had [=NPCs=] join you, often as part of {{Escort Mission}}s, dating all the way back to ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]''. There, they are simply a face in the upper corner of your screen (essentially just a reminder that they are there) and they do not assist you in fighting, and cannot get hurt or die, significantly downplaying the trope.
193** ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' is the first game in the series to have [=NPCs=] actually follow you, where they do engage in combat and can be harmed/killed. Unfortunately, due to the still-primitive AI, ArtificialStupidity makes virtually every follower in the vanilla game more of a liability than anything else. The only commands available (and they aren't available for all followers) are "Wait Here" and "Follow Me". If they're actively following you, even if they're a withered old pilgrim who begged you to escort her to a nearby shrine, they will engage any hostile enemies you come across in combat. You also cannot give them better equipment (by default) to make them more useful (though one dedicated mercenary follower-for-hire in the ''Tribunal'' expansion allows for this), meaning that the unarmed, unarmored, low-level peasant you are escorting will run off, fists a-swinging, at that mighty [[DemonicSpiders Daedroth]] (and will probably perish in two-hits, breaking any quest he is involved with). {{Game Mod}}s are plentiful which improve followers in many ways, making them much more useful.
194** ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'' has a number of the same flaws as vanilla ''Morrowind'', but does mark plot-important characters as "Essential", so they cannot be killed. Several essential characters join you in various quests as followers, and there are some tricks (like reverse pick-pocketing) to give them stronger equipment, making them somewhat more useful. Unfortunately, due to ''Oblivion''[='s=] broken LevelScaling system, these followers do not level up with you while the enemies of the world do. Expect to see even your essential followers "knocked out" after a few hits in combat once you've reached higher levels.
195** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' overhauls the "follower" system in a similar vein to {{Creator/Bethesda}}'s ''{{VideoGame/Fallout}}'' sister series, making them markedly more useful. Quite a few are extremely powerful and can function as DiscOneNuke companions if you recruit them at early enough levels. Some can be hired at any time, while others will only follow you as part of quests or after certain quests. A particularly powerful example is Mercer Frey, the leader of Riften Thieves Guild [[spoiler:who turns out to be a traitor and the main antagonist of the Thieves Guild questline]]. Mercer will follow the Dragonborn during one quest, and although you cannot command him, access his inventory, or sneak with Mercer in tow, nothing stops you from leading him around away from the quest and letting him nuke your adversaries for a few hours.
196* ''VideoGame/EternalSonata'' has Claves, who joins for a dungeon before [[spoiler:getting killed off]]. You can get her to rejoin for the last boss, however, by completing the BonusDungeon.
197* Happens on rare occasions in the ''VideoGame/EtrianOdyssey'' games:
198** ''VideoGame/EtrianOdysseyI'': In ''The Millennium Girl'' remake, [[spoiler:Ren and Tlachtga]] will join the protagonist for the first mission in Story Mode, and [[ATasteOfPower are at least thirty levels higher than him]].
199** ''VideoGame/EtrianOdysseyIIHeroesOfLagaard'': In ''The Fafnir Knight'' remake, [[spoiler:Wulfgar]] hops aboard for your first time through the first floor in story mode. At level 12, he's [[ATasteOfPower stronger than the rest of the party]], but not as strong as the examples above. [[spoiler:Hrothgar]] also joins for the fight against the Chimaera in story mode. He's level 16, about equal level with the recommended level to fight the boss. [[spoiler:Marion]] also serves as a guest party member for the first fight against the Great Dragon in the postgame, but unlike the former two examples, by this point it's already likely your party is on par with, or even stronger than her.
200** ''VideoGame/EtrianOdysseyIIITheDrownedCity'': There are computer-controlled guest characters who you can fight alongside during sea quests. Amusingly, you're THEIR guest star, since they're the quest givers and you're helping them solve their problem.
201** ''VideoGame/EtrianOdysseyIVLegendsOfTheTitan'': During the main story of the game, you can optionally let a supporting character join you as you explore the last floor of the current stratum, until after the upcoming boss fight: Wufan in Misty Ravine, Kibegami in Golden Lair, and Logre in Echoing Library. Afterwards, you can choose whether or not to have them as permanent members of your party. During the postgame, Prince Baldur, Kirjonen and Wiglaf will join you when you confront for the first time the Great Dragon, Blizzard King and Storm Emperor respectively.
202** ''VideoGame/EtrianOdysseyVBeyondTheMyth'': Lili will join you during the fight against the Undead King in Fetid Necropolis. During the postgame, when exploring the BonusDungeon (Empyreal Bridge), Arken will accompany you as you aim to take her to the final floor (though she cannot fight during battle; at least you don't have to protect her either). Also in the postgame, you'll play sidequests where you're accompained by a supporting character as you look for {{Superboss}}es: Jenetta when looking for Dryad in Tutelary Forest, Egar when looking for the Primordiphant in Jagged Reach, Solor when looking for the Zombie Dragon in Fetid Necropolis, and Mirina when looking for Lamia in Lucent Hollows (luckily, all of them ''do'' help you during battle).
203** ''VideoGame/EtrianOdysseyNexus'' has Charis, who can optionally join you during the fight against the Wicked Silurus in Waterfall Wood (as a caveat, if your party already has five characters, Charis will be added as an extra sixth; because of this, Hero-class characters won't be able to cast Afterimages, and Ninja-class characters won't be able to use Mirages). In other strata and mini-dungeons, whenever a character joins you, they won't fight in battle nor need to be protected, but do have field-based skills that are useful during standard exploration.
204* ''VideoGame/Fallout1'' had a quest for you to rescue Tandi, the daughter of Shady Sands' leader, from a nearby raider camp. The game places her as a party member for the purposes of returning her home, but nothing really prevents you from taking her along to other places.
205* Liberty Prime in ''VideoGame/Fallout3'', a Pre-War bipedal robotic superweapon armed with laser eyes, spouts [[RuleOfFunny hilarious]] [[EagleLand jingoistic propaganda]], and throws scaled down nuclear bombs like footballs. Also, he's technically a part of the environment, and is thus indestructible. Admittedly, you're basically his guest star party member at that point in the game, but it's still awesome.
206* ''VideoGame/FalloutNewVegas'':
207** The base game has [=NPCs=] that will fight alongside you for certain quests, like Deputy Beagle in the Bison Steve Hotel, Logan when scavenging Camp Searchlight, Ranger Bryce Anders helping you kill the Fiend leader Motor-Runner in Vault 3, and Private Halford in the Camp Guardian Caves, as well as New California Republic troopers and rangers if you call for backup on the emergency radio. They lack GameplayAllyImmortality, and except for Beagle, you can't trade weapons and equipment with them. There's also the companions all four DLC campaigns, since you can't take them into the main game.
208** ''Dead Money'' has Dean Domino, Christine, and [[SplitPersonality Dog/God]].
209** ''Honest Hearts'' has Follows-Chalk, Waking Cloud, and [[spoiler:Joshua Graham, the legendary Burned Man]]. In fact, the latter can be considered an inversion since that character doesn't fulfill most of the functions other companions do, you ''will'' struggle to keep up, and you ''will'' be ditched if you become a hindrance. In effect, YOU are the companion during that sequence.
210** ''Old World Blues'' has one you can actually create (multiple times, no less, should she die) - Roxie the cyberdog. However, she won't leave the X-8 facility. [[spoiler:If she's alive in the ending, however, she'll escape the Big Empty and have a litter of cyberpups with Rex.]]
211** ''Lonesome Road'' has an odd twist on the concept: [[spoiler:the companion is ED-E, but it is a ''copy'' of the Mojave ED-E with the same stored data but somewhat different abilities. Ulysses, the BigBad of the DLC and the GreaterScopeVillain of the other three, can also become a temporary companion if you convince him to back down.]]
212* ''VideoGame/{{Familia}}'':
213** Marlene temporarily joins Poki and Koko when the Conjurer attacks them. [[spoiler:She can't permanently join because she dies in a MutualKill with the Conjurer.]]
214** Sero the Sage joins Lono when the latter is stranded on a desert island, though he leaves once they make it back to Kalbi.
215* To be expected in a franchise as long-running as ''Franchise/FinalFantasy'':
216** ''VideoGame/FinalFantasyII'' has a whole stream of guest party members. Rest assured that whoever joins your party and fills the fourth slot will eventually leave. [[spoiler:The sole exception is Leon]]. In the GBA and PSP versions, some of them, [[spoiler:more specifically, those who died]], feature in a bonus section after the main game, complete with whatever equipment and magic they had when they left, making SoLongAndThanksForAllTheGear actually '''useful''' for once. However, unless you power-leveled all of these characters in the main game, they will likely get murdered by the more powerful enemies.
217** ''VideoGame/FinalFantasyIII'' has guests for several points in the game. Some of them stick around for multiple dungeons and some for just one. In the original game, they just tagged along as an extra sprite on the map screen, but they have a chance of popping in at the beginning of battles and either casting a spell or attacking in the remake. Their luck varies--a few of them eventually die via HeroicSacrifice and one gets a DisneyDeath, but not all of them.
218** ''VideoGame/FinalFantasyIV'':
219*** In general, the entire party gets well-shuffled over the course of the game. Cecil is the only character that [[CantDropTheHero you must have in your party]], and only a few (Rosa, Rydia, Tellah, and Edge -- out of 11 characters) stick with Cecil for more than three dungeons at a time. Kain and Rosa function as guests when they first join the party, departing again fairly quickly. [=FuSoYa=] sticks around for only a single dungeon near the end. Edge is the only party member who permanently joins when you first get him (and Cecil, though he does change class and gets his level reset to 1). In the GBA remake, as well as the mobile and PSP versions (but not the DS version) most characters are available for the final dungeon and the bonus dungeons, making Tellah and [=FuSoYa=] the only real guests in those games.
220*** The PSP-exclusive Interlude does a similar thing, shuffling members in an out as the story goes on. Here the final party is slightly different from the first game, Cecil, Palom, Porom, (the two replacing Rosa and Kain) Rydia, and Edge.
221** ''VideoGame/FinalFantasyIVTheAfterYears'' follows the grand tradition of temporary party members. Most of them either do not gain experience, or have a lower level cap than the normal characters do.
222*** A handful of permanent party members show up as guests in other chapters: Cecil, Cid, and Rosa in Ceodore's Tale [[labelnote:Details]]Cid and Rosa join for real in Kain's Tale, while Cecil returns in the Final Chapter[[/labelnote]]; Palom, Rydia and Kain in Porom's Tale. [[spoiler:Though "Kain" is actually Dark Kain, who is also a Guest in Kain's Tale until he's defeated by the real Kain.]]
223*** In terms of pure examples: Biggs and Wedge are guests for the first part of Ceodore's Tale. PlayerMooks are available in certain chapters. The Elder of Mysidia joins for a single battle in Porom's Tale. Fusoya appears in the Lunarian's Tale.
224** ''VideoGame/FinalFantasyV'' has one that would otherwise seem like a permanent party member: [[spoiler:that would be Galuf]]. Don't despair if you invested a lot of time {{level grinding}}, as learned abilities carry over to a replacement character: [[spoiler:his granddaughter Krile]].
225** ''VideoGame/FinalFantasyVI'' has a slew of these:
226*** Biggs and Wedge, the two RedShirt soldiers who accompany Terra in the intro sequence. They die shortly into the game.
227*** The 11 Moogles who join to help protect Terra. {{Subverted|Trope}} in that you can recruit one of them as an optional character later, and you can get another through a {{g|oodBadBugs}}litch. (The Moogles are based on characters you get later; if you {{sequence break}} your way out of recruiting one of them, you get the Moogle back at a mandatory point later.)
228*** Banon has a {{game break|er}}ing healing ability. Which is good, because his section of the game is an EscortMission, and if he falls [[NonStandardGameOver it's an automatic Game Over]].
229*** The Ghosts in the Phantom Train are pretty useless other than their [[TakingYouWithMe Possess ability]]. You can fill your open party slots with them (up to two if you didn't recruit Shadow) but they will leave before you deal with the engine.
230*** General Leo is playable for '''one battle'''. [[spoiler:He dies shortly after.]]
231*** Finally there is Shadow, a rare '''Recurring''' Guest Star Party Member. He can be optionally recruited at three different points during the game, though for the first two, he has a random chance of leaving at the end of a battle. He can become a permanent party member if you [[spoiler:wait for him before escaping from the Floating Continent, otherwise he dies]].
232** ''VideoGame/FinalFantasyVII'' has a couple:
233*** Aerith is an unusual example in that, by all appearances, she's a permanent character [[ItWasHisSled up until she dies]]. She gets everything that all the other characters can: an InfinityPlusOneSword, a full set of {{Limit Break}}s, and more {{character development}} then anyone else up to that point. Of course, if you didn't know she was going to leave, you probably wouldn't come across those power-ups until after the fact.
234*** Sephiroth. Though you never actually control him, he is every bit TheAce that Cloud touts him as. [[PurposelyOverpowered He has powerful attacks, powerful magic, and is a great healer, too]]. He also comes equipped with a full set of Master materia, just to break him even further. Too bad you only get him briefly in the flashback; he'd be a GameBreaker otherwise.
235*** At the end of the first part of the [[VideoGame/FinalFantasyVIIRemake remake]] Red XIII becomes one, as this part ends after Midgar and Red XIII was only available for a couple of battles in the Midgar section of the original. Also overlaps with EleventhHourRanger.
236** ''VideoGame/FinalFantasyVIII'':
237*** Seifer is useful for low-level players at the start of the game.
238*** Edea is less welcome, as her abilities and LimitBreak are fairly useless by the time you get her. Using Edea is also completely optional unlike the other guests, so many players will quickly ditch her once the novelty wears off, if they use her at all.
239*** Laguna, Kiros, and Ward are a whole Guest Star Party.
240** A number in ''VideoGame/FinalFantasyIX'':
241*** Beatrix assists the party for a short while early on, and then a little later in a duo with Steiner for a segment that mainly exists so that Steiner [[CantCatchUp can catch up]]. Though she's pretty powerful when she's playable, you can kill her off in the Steiner section so that Steiner gets even '''more''' experience from the ordeal.
242*** Cinna, Blank and Marcus. Cinna joins for the first two fights of the game, and earns the distinctions of "lowest attack", "lowest defence", and generally "crappiest character." Blank also joins for the first few fights, leaves for a while, then comes back for the Plant Brain boss fight before getting turned to stone. Marcus is around for the same fights as Blank and Cinna, but he rejoins later when Dagger and Steiner split up from the main group. He's a Zidane clone, with slightly higher attack. (In fact, that last sentence applies to all three.) However, some of these guests transfer their stats to permanent party members (Blank and Marcus carry over to Amarant and Eiko respectively). Leveling with them makes future party members that much more powerful.
243*** Although you never enter any battles as him, you do play as Regent Cid in his frog form to save the party when they’re captured in Kuja's Palace. This involves walking around the palace, a stealth segment, and then a minigame balancing weights on a scale all under a time limit before Kuja kills the party.
244** Seymour in ''VideoGame/FinalFantasyX''. He joins you for only one battle: [[spoiler:the second fight against Sinspawn Gui]]. He even has an [[LimitBreak Overdrive]] of his own!
245** ''VideoGame/FinalFantasyXII'' explicitly makes guest party members a game mechanic: the character is actually labelled "Guest" in the menu, doesn't count toward the party's ArbitraryHeadcountLimit, has permanently-set equipment, and has no Licence Board entry. The guest will only level up and be given commands in the [[UpdatedRerelease Zodiac version]]. There are six primary examples of guests over the course of the game:
246*** Reks is the DecoyProtagonist for the prologue of the game and promptly bites it.
247*** Amalia (who's actually Ashe) and Basch join for the long haul later. Balthier practically {{lampshade|Hanging}}s the trope the first time it occurs, outright calling Amalia the party's "guest" (using the terminology from ''VideoGame/FinalFantasyTactics'', set in the same universe) and basically explaining all the above mechanics without quite breaking the fourth wall.
248*** Larsa stays as an important character in the game.
249*** The last two guests are Vossler and Reddas. [[spoiler:As with Reks, they get axed.]]
250*** There's also a plethora of friendly minor [=NPCs=] during certain Monster Hunts who your party will treat as temporary party members (which can be annoying when they start trying to buff a guy who's got Reflect).
251*** Finally there's a character who doesn't join the party but helps out in battle: [[spoiler:Gabranth shows up in the penultimate battle against Vayne]].
252** And again in ''VideoGame/FinalFantasyXIIRevenantWings'', with [[spoiler:Ba'Gaman and Fran]]. The latter of these two characters joins your party again, and thankfully there is never equipment to buy for the first character so there's no potential for thievery.
253** ''VideoGame/FinalFantasyXIII'' has Gadot and Lebreau, Snow's [[TheLancer lancers]] in his anarchy/resistance group. They fight with him in chapters 1 and 2 and function as {{Crutch Character}}s.
254** Lightning and Snow are DemotedToExtra in ''VideoGame/FinalFantasyXIII2''. While Lightning is temporarily playable, Snow is a straight-up guest.
255** Fang joins Lightning at a couple of points in ''VideoGame/LightningReturnsFinalFantasyXIII'' and is fully controlled by the [=AI=]. Lightning can also fight alongside the Angel of Valhalla in the Wildlands if you complete the quest for that.
256** In ''VideoGame/FinalFantasyXV'', Grand Marshall Cor Leonis helps you out a little bit early on; he is level 52 when you'll be in your teens. Also joining in on the fun are Iris Amiticia and Aranea Highwind: the former doesn't boast much HP but is surprisingly effective in a fight for being a 15 year old girl, using her dolls, martial arts, and potions to be useful; Aranea, meanwhile, is a powerful dragoon who comes at a time when your party is a man down. And she can also temporarily join your party for tough battles in the field later on as well. And, due to an easy to exploit glitch, she can be made into a permanent member of the party. Cor actually lampshades it in a dialogue with Noctis.
257--->'''Noctis''': Life's a lot easier with you around!\
258'''Cor''': Don't get used to it. I'll be gone before you know it.\
259'''Noctis''': I'll enjoy it while it lasts, then.
260** In ''VideoGame/FinalFantasyXVI'', the player's party typically consists of Clive, Torgal, and a rotating stable of NPC companions. Wade, Tyler, and Murdoch accompany Clive during the prologue, Cid, Gav and Byron accompany the party for overworld gameplay segments throughout the game, and Jill and [[spoiler:Joshua]] can be recruited permanently into the party for the final overworld part (although Jill doesn't accompany you to the final battle and [[spoiler:Joshua]] does not see any combat during said final battle). [[spoiler:Wade]] and Theodore also accompany you for a couple of sidequests and actually occupy a specifically mentioned "guest" slot.
261** ''VideoGame/FinalFantasyAdventure'' has a couple of [=NPCs=] that join you at certain points of the game: a girl ([[AllThereInTheManual named Fuji in the manual]]), a red mage that shoots fireballs [[spoiler:and turns out to be Julius the Big Bad]], Watts, a knight, a sibling pair of a bard and a dancer, and a robot. Most of them return in the VideoGameRemake, ''VideoGame/SwordOfMana'', with a few exceptions.
262** ''VideoGame/FinalFantasyMysticQuest'' gives you a different guest party member for each of the regions of the world. Each one of them joins exactly twice.
263** ''VideoGame/FinalFantasyDimensions'' makes this a core feature of the plot, which is divided into chapters. Each of the storyline's two major groups consists of four characters, but the ArbitraryHeadcountLimit is five; at almost all times, the fifth slot is filled by a guest character who possesses a unique CharacterClass, which becomes available to the rest of the party upon completion of the current chapter.
264** ''VideoGame/FinalFantasyTactics'' and its sequels have characters that join you temporarily. The first ''Tactics'' game have guest characters that accompany you for a while until the plot calls them away. The later games only have guest characters appearing for specific battles and don't stick around once the battle is done.
265* ''VideoGame/GameMasterPlus'':
266** Varia and Origin are summonable AI-controlled party members. They can only be summoned once per battle through their runes and their runes have to be recharged by resting before they can be summoned again.
267** [[spoiler:All the human party members in Grandora Island are illusionary versions created from Elsa's imagination rather than proper [=AIs=] from Espheria. These include Eloire before her SanitySlippage, Hemrock's original human self, and Vaille. Since they're imaginary, they are temporary comrades that can only exist in Grandora. Unlike Varia and Origin, they can be controlled in battle and their equipment can be changed.]]
268* The first ''VideoGame/GoldenSun'' game has [[FieryRedhead Jenna]] join the party early on, but she [[spoiler:is kidnapped]] after the first dungeon. She only becomes fully playable in the second game. When you know it's coming you can easily take her stuff, but her [[ChainmailBikini One-Piece Dress]] isn't going to do your now all-male party any good. The most she can [[SoLongAndThanksForAllTheGear steal]] at that point is a few herbs and some wimpy armor, anyway. The third game, ''[[VideoGame/GoldenSunDarkDawn Dark Dawn]]'', has Isaac and Garet tag along for the first dungeon, though they aren't directly controllable.
269* The first ''VideoGame/{{Gothic}}'' features a variety of individual quest allies who fight alongside you but otherwise do whatever they want. Notably, you are helped more frequently by Diego and Gorn. And then there's Mud.
270* ''VideoGame/GrandiaIII'': Hect joins you for a couple of dungeons late in the game, because [[spoiler:she replaces Alfina, who is currently kidnapped. When Alfina is freed and it's time for the final battle, she stays behind to make a magical bridge towards the FinalBoss]]. She's a bit PurposelyOverpowered, so you don't have to learn her playstyle so late into the game.
271* In the original ''Franchise/DotHack'' quadrilogy there was Mia, who was available for most of the 1st volume (but not available for important story events that didn't involve her) but only one dungeon and post game only in the 2nd [[spoiler:as the corruption of the game data was starting to affect her]], not available at all in the 3rd [[spoiler:having disappeared completely as the Phases were defeated and the corruption spread]], and only available in the 4th after you finish the post game epilogue dungeon [[spoiler:after which Aura resurrects her, as you had to defeat her in Phase form earlier in the game]]. There was also Orca who was only available for the first dungeon [[spoiler:after which Skeith puts him in a coma]], and then didn't return until the endgame of the final volume. Elk and Mistral are only a partial example as they are available for all of the 1st and 2nd games, but not the 3rd [[spoiler:as Mistral bows out with her player revealing her pregnancy and Elk leaves to find Mia]], but come back halfway through the 4th.
272* In ''VideoGame/HolyUmbrella'', BigBad Emperor Dondera serves as a party member while [[WombLevel inside the Mammoth Whale]].
273* ''VideoGame/InfiniteSpace'' has several, whether as a ship that temporarily joins your fleet or as temporary crew members (three of whom become permanent members later), most notably Cico's Rudianos in Act 1 and both Dietrich and Nele in Act 2.
274* In the anime RPG ''VideoGame/InuYashaTheSecretOfTheCursedMask'', Sesshomaru joins you for a brief stroll around a castle, until you reunite with your party inside. His high stats and powerful combat abilities make him functionally invincible against the much weaker enemies you encounter. If you jump though a ton of hoops to raise his affection up he'll join the the female PC (but not the male) for the final battle and give you a special ending.
275* Sagacious Zu of ''VideoGame/JadeEmpire'' is a strong character, but [[spoiler:dies saving the player from Death's Hand at the end of Chapter 3.]] There's also Abbot Song, who joins the player after [[spoiler:the PC is killed by Master Li. He fights alongside the PC until the Water Dragon's power is restored.]]
276* ''Franchise/KingdomHearts'':
277** Many of the worlds you visit include a guest who can swap into the party in that world only. These characters never need equipment (most don't need weapons or armor, the rest come with what they need), they leave if you exit their world, and they replace one of your permanent party members (WesternAnimation/DonaldDuck or WesternAnimation/{{Goofy}}). One wonders why the designers didn't just put in a fourth party slot and leave it empty most of the time -- but then Square-Enix has mostly stuck with 3 character parties since ''VideoGame/ChronoTrigger''.
278** The guest star party members introduced in the original game are WesternAnimation/{{Aladdin}}, [[WesternAnimation/TheLittleMermaid1989 Ariel]], [[WesternAnimation/TheNightmareBeforeChristmas Jack Skellington]], WesternAnimation/PeterPan and the [[WesternAnimation/BeautyAndTheBeast Beast]] (there was also WesternAnimation/{{Tarzan}}, but due to copyright complications, Disney prefers to pretend [[CanonDiscontinuity he was never in the game]]). Aladdin actually asks to accompany the party for the rest of the game after you complete the story in Agrabah. He is refused since most people aren't supposed to know that other worlds exist, [[FridgeLogic even though by that point he already does]].
279** There is also one special case that doesn’t follow the game’s usual rules but is still an example of this trope for one battle only. That would be [[TheRival Riku]] during the first Parasite Cage bossfight in Monstro. He fights alongside you, dealing damage and even healing you, but he doesn’t even have a health meter of his own, let alone a place on the game’s menu like other party members. This makes sense, because [[spoiler:while after his FaceHeelTurn, it’s still early enough that he’s on the fence about that decision. Sora refusing Riku’s offer to help for the second battle, due to Riku’s mistreatment of Pinocchio, is what ultimately seals the deal on them truly being enemies from that point forward]].
280** In ''VideoGame/KingdomHeartsII'', Ariel and Peter Pan lose this status, but WesternAnimation/{{Mulan}}, [[VideoGame/FinalFantasyX Auron]], [[Franchise/PiratesOfTheCaribbean Jack Sparrow]], [[Franchise/TheLionKing Simba]], and Film/{{Tron}} are all introduced as party members, and [[spoiler:Riku]] becomes one [[spoiler:two areas before the final boss in The World That Never Was]].
281** Mostly used in the second game (but occasionally in the others), there are times when characters will join you in battle as an unofficial "fourth" party member, acting as allies but not showing up in the HUD. Examples include Minnie Mouse at Disney Castle, as well as several ''Final Fantasy'' cameos such as Leon (Squall) and Cloud.
282** ''[[VideoGame/KingdomHearts358DaysOver2 358/2 Days]]'' has practically only this in the story mode: Roxas either fights alone, or with another Organization member specified by the mission. You have no control over them, aside from selecting one of three general behaviour options.
283** ''[[VideoGame/KingdomHeartsBirthBySleep Birth By Sleep]]'' does the same thing as ''358/2 Days'', with the guest star party members being the other two Keyblade masters you aren't playing as, [[WesternAnimation/SleepingBeauty Prince Philip]], young WesternAnimation/{{Hercules}}, [[VideoGame/CrisisCore Zack]], [[WesternAnimation/LiloAndStitch Experiment 626]] and WesternAnimation/MickeyMouse. All only appear for a few battles, but unlike in ''II'', they will show up in the HUD.
284** ''VideoGame/KingdomHeartsIII'' not only continues the trend, but does away with the ArbitraryHeadcountLimit, allowing the guest to fight alongside your full team.
285*** Party members include Hercules in Olympus, Woody and Buzz in [[Franchise/ToyStory Toy Box]], Rapunzel and Eugene in [[WesternAnimation/{{Tangled}} Kingdom of Corona]] (though Rapunzel leaves permanently after reaching the festival), Sulley and Mike in [[Franchise/MonstersInc Monstropolis]], Marshmallow in [[WesternAnimation/Frozen2013 Arendelle]], Jack Sparrow in Port Royal, which has now been renamed "The Caribbean", and Baymax in [[WesternAnimation/BigHero6 San Fransokyo]].
286*** During the climatic battle in the Keyblade Graveyard, Aqua, Ventus[[labelnote:*]]vs. Terra-Xehanort and Vanitas[[/labelnote]], Riku[[labelnote:*]]vs. Dark Riku and Xigbar; later vs. Ansem, Xemnas, and Young Xehanort[[/labelnote]], Mickey[[labelnote:*]]vs. Luxord, Marluxia, and Larxene; later vs. Ansem, Xemnas, and Young Xehanort[[/labelnote]], Lea, Kairi[[labelnote:*]]vs. Saix and a hooded girl[[/labelnote]], [[spoiler:Roxas, and Xion[[labelnote:*]]vs. Saix; they replace Lea and Kairi[[/labelnote]]]].
287*** The [[=Re:Mind=]] DLC [[InvertedTrope inverts this]] with four battles where [[TheHero Sora]] is the guest, three involving Riku, Aqua and [[spoiler:Roxas]] in a OnceMoreWithClarity style boss battle, and one involving ''[[PromotedToPlayable Kairi]]'' for a [[spoiler:PostFinalBoss]].
288* Trask in the [[HeKnowsAboutTimedHits opening tutorial]] of ''VideoGame/KnightsOfTheOldRepublic''. To some extent, this also applies to [[spoiler:Bastila]].
289** ''VideoGame/KnightsOfTheOldRepublicIITheSithLords'' has 3C-FD, who you can take control of in the tutorial, and B-4D4, who you control for a brief sequence during a storyline quest after [[spoiler:stealing and reprogramming him]]. In addition, under similar circumstances to the above spoiler character, this technically applies to [[spoiler:Kreia]].
290** In ''VideoGame/TheJediMasters'', [[spoiler:Kreia]] briefly returns as a party member when searching for Revan at his last known location.
291* [[spoiler:Count Arganan]] in ''VideoGame/TheLastStory''. At one critical moment of the game, he forces his way into your party until [[spoiler:the source of the power of the Outsider disintegrates him]]. The game also gives you General Asthar, Sir Therius, and Horace as guest star party members at different points in the game. Asthar is often much stronger than the player party, while Therius is generally on par with them, and Horace is a virtual [[NonActionGuy non-combatant]], being a shopkeeper who gets roped into the group's zany adventures from time to time.
292* ''VideoGame/TheLegendOfDragoon'' had two, Lavitz and Shana. Similar to the above, when they leave they are instantly replaced with an equivalent party member. Albert may be arguably greater than Lavitz due to joining early and having more time for Character development, while Miranda was practically an AssPull and was thrown in to simply replace Shana so she could fulfill plot purposes, and for the possibility that someone actually ''did'' use Shana religiously (Shana and Miranda are a mixed bag -- some players will insist they're underrated, while others will say they're both worthless and Meru can do anything they can).
293* ''VideoGame/LikeADragonInfiniteWealth'' has multiple instances of this.
294** Saeko fights alongside Ichiban at one point during their date in Chapter 1, and then does not show up again until she joins Kiryu's party in Chapter 8. Later on in Chapter 1, Nanba and Adachi join forces with Ichiban, but leave when Ichiban goes to Hawaii and do not return until Chapter 7.
295** There are also multiple characters who are AI-controlled and help out in a few fights, and the game still counts them as party members. To wit, Eiji in Chapter 2, up through the first fight against [[RecurringBoss Yutaka Yamai]]; Yamai himself pulls an EnemyMine and fights alongside Ichiban for one fight in Chapter 9; Asakura teams up with Ichiban for the final fight in his substory chain; and [[spoiler:Daigo, Majima, and Saejima]] all team up with Kiryu against a horde of Seiryu Clan grunts in the final chapter.
296* ''VideoGame/LunarLux'': In the first battle against multiple enemies, two nameless Lunex Soldiers will assist Bella. This causes the Lunex Soldier support skill to activate automatically after Bella's active skills. The demo originally had the damage set to 40, but was buffed to 100 in the full release, which is equivalent to the skill's damage when its level is maxed.
297* ''VideoGame/TrailsSeries''
298** ''VideoGame/TheLegendOfHeroesTrailsInTheSky SC'' has Anelace Elfead become playable during the prologue, as well as a sidequest later in the game. Said side-quest also provides the only instance in which Kurt Nardin is playable.
299** ''[[VideoGame/TheLegendOfHeroesTrailsFromZeroAndTrailsToAzure Zero]]'' has Noel Seeker, Wazy Hemisphere, Alex Dudley, and [[spoiler:Yin]] join the party for specific parts before leaving, though ''Azure'' promotes at least half of them to main character status. Speaking of ''Azure'', Arios [=MacLaine=] and [[spoiler:Garcia Rossi]] are both playable for one instance each.
300** The ''[[VideoGame/TheLegendOfHeroesTrailsOfColdSteel Cold Steel]]'' games love you to load you up with guest star party members and more and more as the series goes on. By the fourth and final game, a total of 39 characters are playable and only a bit less than half of those are considered regulars and not guests. Guests generally have fixed equipment (either fixed weapons or both fixed weapons and armor/accessories) and fixed quartz (lets you cast magic), but make up for it by having better stats and coming equipped with powerful equipment and quartz early on that the player may not yet have access to. Thus, they can sometimes be a CrutchCharacter, though they're generally not good to use on a NewGamePlus if carrying over equipment and quartz, as your own party can easily outclass them.
301** ''[[VideoGame/TheLegendOfHeroesTrailsIntoReverie Reverie]]'' has Elise, [[spoiler:Aurelia, and Olivier]] has temporary party members during Rean's route, but are only fully playable in the [[BonusDungeon True Reverie Corridor]].
302** ''[[VideoGame/TheLegendOfHeroesTrailsThroughDaybreak Daybreak]]'' has about 6 playable guest party members[[labelnote:SPOILERS]]Elaine, Fie, Zin, Yin/Rixia, Shizuna, and Kincaid[[/labelnote]] and 4 non-playable allies.[[labelnote:SPOILERS]]Cao, Walter, Lucrezia, and Kurogane[[/labelnote]] The second game promotes a few of the playable guests to main character status,[[labelnote:SPOILERS]]Elaine, Shizuna, and Kincaid[[/labelnote]] while adding in 2 others who are only fully playable in the [[BonusDungeon Marchen Garten]].[[note]]Celis and Leon[[/note]]
303* There are several of these in ''VideoGame/TheLordOfTheRingsTheThirdAge'', including Aragorn (twice), Legolas, Gimli, Gandalf (twice), Éowyn, and some random Elf guy (multiple times). Each of them joins your team for a single battle or a series of consecutive battles, then leaves immediately afterward without so much as saying goodbye.
304* ''VideoGame/LufiaIIRiseOfTheSinistrals'' has Tia, Dekar, and Lexis as temporary party members. You'll know this if you've played [[VideoGame/LufiaAndTheFortressOfDoom the prior game]], which begins with Maxim and his final party at the end of their journey. [[AvertedTrope Averted]] in [[VideoGame/LufiaCurseOfTheSinistrals the remake]]: Tia joins permanently, Dekar rejoins [[spoiler:after returning from his HeroicSacrifice]], and Lexis is [[DemotedToExtra non-playable]] but sticks with the party from the very beginning.
305* Bau in ''VideoGame/LufiaTheRuinsOfLore'' first joins as a Guest Star Party Member before permanently joining later. [[spoiler:Dekar]] is a straight example, [[EnsembleDarkhorse sadly]].
306* ''VideoGame/LuminousPlume'': In the Mystic Forest, Valerie is an AI-controlled ally capable of using the same techs from her boss battle, only she's also using her recently learned aura skills. She later joins again in the Northern Plains and leaves [[spoiler:after the battle with the Black Blade.]]
307* ''VideoGame/LunarTheSilverStar'':
308** Ghaleon, Laike, and Tempest. Laike has a stupid-high attack rating, while Ghaleon possesses an array of destructive magic that makes Alex's weapons look wimpy in comparison. There's a reason behind both of them, though: [[spoiler:Ghaleon is actually the Magic Emperor, the game's BigBad; and Laike is really Dyne, the legendary Dragonmaster [[FakingTheDead everyone believed to be dead]].]] Tempest? He just shows up for one mission when all of the female party members fall unconscious, and is barely heard from again.
309** There's also Ramus and Luna (especially in the original game) who although higher party members than the above three (for example, their equipment can be removed and replaced with better stuff) still don't last that long in the game before being replaced with other characters. Ramus works with Alex for the first three dungeons up until the one in Meribia where he leaves Alex's party to open a shop. Luna permanently leaves Alex's party when he heads to Meribia in the original game. In all remakes, she notably goes with him to Meribia and lasts longer into the story, up until [[spoiler:Ghaleon pulls his FaceHeelTurn and abducts her to awaken her memories as the reincarnation of the Goddess Althena]], after which she's gone for good.
310* ''VideoGame/LunarEternalBlue'':
311** Aspects of this trope are seen in the heroine, Lucia, who is a party member for most of the game, but is not under the player's direct control. She starts out as a CrutchCharacter, but spends most of the game in a {{depower}}ed state. Then, after leaving the party late in the game, she returns for an event battle at the very end.
312** Hiro's grandfather Gwyn. He fights alongside Hiro for the first dungeon or so, then permanently leaves for the rest of the game. There's also Leo, who often fights alongside Hiro's group for a couple dungeons whenever Lucia's not around. [[spoiler:In the game's playable epilogue he joins for good to help Hiro reunite with Lucia]].
313* ''VideoGame/MarvelUltimateAlliance'' has three: Dum Dum Dugan, Corsair, and Nick Fury himself (before becoming an unlockable character). Dugan shows up at the beginning of the first mission in Act I and the heroes must fight alongside him while protecting him; if his health runs out the mission must be started over. Corsair shows up during a mission in Act 4 where he will fight alongside the party for the first screen before separating from them and communicating with them over a radio. Fury fights alongside the party at the beginning of Act 5 when the corrupted Stark Tower comes under attack by Dr. Doom's forces.
314* ''Franchise/MassEffect'':
315** Jenkins in [[VideoGame/MassEffect1 the first game]] kinda fits this trope, but all you can do with him is talk to him on the Normandy and Eden Prime (where he is actually quite knowledgable about the area and wildlife, being from the colony). Once you first meet the enemy, he dies almost immediately. You can even assign him skill points, but they're useless since he dies before he gets to fire a shot.
316** ''VideoGame/MassEffect2'' gives us Wilson, the chief medical tech in charge of [[spoiler:bringing Shepard back to life]]. He accompanies you for part of the tutorial mission before [[spoiler:being shot by Miranda, who takes his place.]]
317*** The "Lair of the Shadow Broker" {{DLC}} makes Liara a longer-lasting guest star, since she accompanies you for two levels. Unlike other guest party members, she has her own skill tree which you can put points into, and upon beating the mission you can even learn to use her Stasis ability as a bonus power, ''a la'' squad loyalty skills.
318*** And then in the "Arrival" DLC, Dr. Amanda Kenson helps Shepard after they bust her out, [[spoiler:until she pulls a FaceHeelTurn and reveals she's been indoctrinated by a Reaper artifact]].
319** Continuing the tradition, Shepard's former CO [[FourStarBadass David Anderson]] is a party member during the introduction of ''VideoGame/MassEffect3''. [[spoiler:Fortunately, he remains an important [=NPC=] who survives all the way to the end of the game while leading the anti-Reaper resistance on Earth.]]
320** Various party members from the first and second ''Franchise/MassEffect'' games, and even one or two characters from the ExpandedUniverse, make guest appearances throughout ''3'', sometimes as party members, and sometimes simply as quest-important [=NPCs=]. [[AnyoneCanDie Be warned, many of these characters are prone to dying dramatic deaths.]]
321** The Omega DLC gives both of Shepard's party slots to guest-stars -- recurring character Aria T'Loak (Omega's ruler), and newcomer Nyreen Kandros.
322** After two games as the krogan SupportingLeader, Wrex returns as a usable party member in the Citadel DLC.
323** The Citadel DLC also has the Armax Arsenal Arena, where you can unlock (most of) your squadmates from ''Mass Effect 2'' (and Wrex) as temporary party members in the combat sim. Combined with your regular party members, this means that you can play with every single regular party member from the trilogy [[spoiler:except Thane, Mordin, Legion, Morinth, the squadmate who died on Virmire, and anyone else who dies over the course of the games.]]
324* The ''VideoGame/MightAndMagic'' series had this featured in some quests where you would have to rescue a maiden or a child and they would tag along until you brought him/her to the person who told you to rescue the maiden/child. Another example is that almost every NPC in the could join your group and provide some sort of benefit while they are with you, sometimes, however, some people will join and do nothing at all except eat your food.
325* Several characters, including the Fab Fairies, the Great Sage or the [[spoiler:ex-Dark-Lord]] accompany the main party at some key points in ''VideoGame/{{Miitopia}}'', providing a fifth member immune to ''anything''. Many Miis can appear in the Traveller's Hub and join the party during an errand the player completes for them, and sometimes these Guest-Star Party Members can be recurited as Full-Time Party Members!
326* ''VideoGame/{{Mother}}'':
327** ''VideoGame/EarthBoundBeginnings'': Pippi, Teddy, and EVE -- Pippi and Teddy were controllable, EVE wasn't. Funnily enough, Pippi has the same base stats as Teddy, and Teddy was depicted as one of the main characters.
328** ''VideoGame/EarthBound1994'':
329*** The beginning of had a number of guest party members, including the hero's dog, his next door neighbors Pokey and Picky, and Buzz Buzz, a bee from the future, who was the only one who could do substantial damage to enemies. Picky would mostly miss the target, while Pokey would always just cower in fear.
330*** Jeff's best friend Tony, who follows him around during the escape from the boarding school but doesn't get into combat. Later he gets followed around by a gum-chewing monkey.
331*** The huge and powerful golem Dungeon Man, who gets stuck in some trees shortly after you meet him.
332*** There are also the Flying Men in Magicant. Unlike other guest party members, they can die and there are a total of 5 of them.
333** ''VideoGame/Mother3'':
334*** There are characters that follow you around like this in the first few chapters, however straighter examples are [[spoiler:Salsa and Flint]], who are the player controlled characters in two early chapters, but do not participate in most of the game. [[spoiler:Salsa does come back for a short time, but leaves permanently afterwards.]]
335*** The first area of Chapter 3 is probably the only time you enjoy Fassad's company: he does the most damage in the first area. [[spoiler:[[{{Jerkass}} He still had it coming.]]]]
336* ''VideoGame/NocturneRebirth'':
337** Shylphiel will assist Luna when the latter traverses the territory of the former's master, Khaos. [[spoiler:When Khaos turns out to be the BigBad, Shylphiel ends up becoming the first boss of the final dungeon.]]
338** [[spoiler:Ristill]], a previous boss, will form an EnemyMine with party against the FinalBoss. She scales to the party's level, which means she won't be as strong as when she was a boss unless the party is very overleveled.
339* ''VideoGame/OctopathTravelerII'' has quite a few for some characters' starting chapter(s): Osvald has Emerald, Throné has Pirro and Scaracci, Agnea has Gus, the bartender of her town, Temenos has Crick, and Hikari has Ritsu and Rai Mei.
340* ''VideoGame/ParasiteEve2'' has Kyle, a detective of some sorts, join Aya's side in a few parts of the game. He only has 100HP but can take hits better than Aya can. He cannot be healed at all, so if he dies, [[WeCannotGoOnWithoutYou Game Over]].
341* Pops up in the ''Franchise/{{Persona}}'' series:
342** In ''VideoGame/Persona1'', you go through the prologue and the first dungeon with a party consisting of Masao Inaba, Yukino Mayuzumi, Kei Nanjo, and Eriko Kirishima. Once you return to St. Hermelin, all of them leave the party. Masao will never return on the Snow Queen route while Yukino will never return on the SEBEC route; Kei and Eriko can both be re-recruited later on (and Kei is outright mandatory for the SEBEC route).
343** In the ''VideoGame/Persona2'' duology:
344*** Yukino Mayuzumi accompanies you for the first part of ''Innocent Sin'', but she either leaves [[spoiler:or is killed off depending on whether or not you take her with you to Caracoal]] about halfway through, and Jun Kurosu permanently takes her place afterward.
345*** In ''Persona 2: Eternal Punishment'', a certain rumor you can spread will allow you to recruit either Kei Nanjo or Eriko Kirishima for a couple of dungeons, but they are eventually dropped in favor of Tatsuya Suou.
346** In ''VideoGame/Persona3'':
347*** [[spoiler:Shinjiro Aragaki]] is this in a roundabout way, as he's only available for one in-game month [[spoiler:before his PlotlineDeath]] (or in ''Portable'', [[spoiler:his incapacitation via coma]]). This is covered up by the fact that his Persona, [[spoiler:Castor]], can learn a full list of skills up to Level 70, whereas your other party members will learn their last skill in the mid 40's, and cannot learn more [[spoiler:until they obtain their Ultimate Personas]], but chances are he won't learn them unless you deliberately go and level grind him.
348*** At the beginning of "The Answer", the PlayableEpilogue exclusive to the ''FES'' UpdatedRerelease and DLC campaign in the ''Reload'' remake, you fight the WarmUpBoss with Aigis' Ultimate Persona from "The Journey", Athena. Afterwards, [[spoiler:Athena metamorphoses into the protagonist's Initial Persona, Orpheus]], and the game truly starts.
349*** In ''VideoGame/Persona3Reload'', the VideoGameRemake of ''P3'', on 8/14, you fight a rogue Shadow on the Moonlight Bridge, [[EnemyMine joining forces with Takaya Sakaki of Strega]], Takaya being a computer-controlled ally.
350** ''VideoGame/Persona5'':
351*** Goro Akechi temporarily joins [[PlayerParty the Phantom Thieves]] for a single late game dungeon by using {{blackmail}} to force his way onto the team. Unlike your permanent party members, who specialize in a single {{Elemental Power|s}}, Akechi has multiple Bless, Curse, and Almighty spells, and gets a wide range of LevelUpAtIntimacy5 party member perks automatically. In the ''Royal'' re-release, he returns for the new third semester content and sticks with you to the end.
352*** In the ''Royal'' re-release, Kasumi Yoshizawa downplays this. She fights alongside you for two battles (her awakening on 10/3 [[DevelopersForesight or 10/4]] and the InMediasRes prologue on 11/19) but doesn't join the Phantom Thieves at this time. She later accompanies you for the mandatory dungeon run on 1/2, leaves the party at the end of that, and finally joins you for real on 1/12.
353* ''VideoGame/PhantasyStar'':
354** Nei of ''VideoGame/PhantasyStarII'' begins the game in the party, and might be a permanent fixture if not for one little snag: [[spoiler:she is part of Neifirst, who must be slain and takes Nei with her one way or another.]] The Japan-only Platform/PlayStation2 remake allows the player to overcome this and keep Nei through the whole story on a NewGamePlus.
355** ''VideoGame/PhantasyStarIV'' has 5 slots and 11 characters, so naturally 6 of them end up as guests. One of these, Seth the archaeologist, is actually pretty competent, with some nasty spells like Deathspell and Corrosion that certainly help with the Soldier's Temple on Motavia. However, he's a particularly blatant case of holding back his true skills by the time he leaves the party. [[spoiler:You end up fighting him as '''he's actually an incarnation of Dark Force''', one of the insanely powerful demons that have served as the Big Bad for the last three games. Given Seth's scream of horror as he transforms, whether he's aware of his own nature is uncertain.]]
356* ''Franchise/{{Pokemon}}'': Starting from ''[[VideoGame/PokemonRubyAndSapphire Emerald]]'', every main series game has at least one NPC trainer to team up with the player to battle.
357** In ''Emerald'', Steven teams up with the player to battle against Maxie and Tabitha in the Mossdeep Space Center.
358** During the main plot of ''[[VideoGame/PokemonDiamondAndPearl Diamond, Pearl and Platinum]]'', Lucas/Dawn as an NPC teams up with the player to battle against Team Galactic grunts in Jubilife City and Veilstone City. Your rival will partner with you at the Spear Pillar to battle against Commanders Mars and Jupiter.
359** In ''[[VideoGame/PokemonDiamondAndPearl Diamond, Pearl and Platinum]]'' and ''[[VideoGame/PokemonBlack2AndWhite2 Black 2 and White 2]]'' there are several dungeons where a friendly [=NPC=] will team up with the player for a short period of time. These [=NPCs=] have their own Pokémon, which they control alongside the player's in Tag Battles.
360** In ''[[VideoGame/PokemonGoldAndSilver HeartGold and SoulSilver]]'':
361*** [[TheAce Champion Lance]] teams up with you in battle at the Rocket Hideout, against Executive Ariana and a Team Rocket grunt.
362*** You team up with your rival to battle Lance and Clair at the Dragon's Den in post-game.
363** In ''VideoGame/PokemonBlackAndWhite'', the player teams up with Cheren to battle on two occasions: first against two Team Plasma Grunts in Wellspring Cave, then against two Preschoolers on Route 5 at Alder's request.
364** In ''[[VideoGame/PokemonBlack2AndWhite2 Black 2 and White 2]]'', the player partners with rival Huge to battle against Team Plasma on multiple occasions.
365** In ''[[VideoGame/PokemonXAndY X and Y]]'', you get to battle along with Calem or Serena (depending on the player character's gender) at the secret Team Flare hideout several times, not far from the final battle with the boss, [[spoiler:Lysandre]]. The Battle Maison's Multi Battle mode allows you to partner with any of your other rivals, Shauna, Tierno, and Trevor.
366** In ''[[VideoGame/PokemonRubyAndSapphire Omega Ruby and Alpha Sapphire]]'':
367*** Brendan or May as a rival teams up with the player to battle against Team Magma (''Omega Ruby'') or Team Aqua (''Alpha Sapphire'') in Meteor Falls.
368*** Steven aids you to battle against against Team Magma (''Omega Ruby'') or Team Aqua (''Alpha Sapphire'') [[spoiler:at the Southern Island during the main plot and at the Mossdeep Space Center during the Delta Episode]].
369*** Like in ''X and Y'', the Battle Maison's Multi Battle mode allows you to partner with certain NPC trainers. This time, your choices include Brendan/May (depending on who is the rival), Wally, Steven and [[spoiler:Maxie (''Omega Ruby'')/Archie (''Alpha Sapphire'')]].
370** ''[[VideoGame/PokemonSunAndMoon Sun and Moon]]'' has your rival, Hau, team up with you in a few battles again some Team Skull grunts and [[spoiler:members of the Aether Foundation. Likewise, Gladion will also team up with you for a few battles in the Aether Foundation]]. The [[BrutalBonusLevel Battle Tree]]'s Multi Battle mode also allows you to partner with notable characters seen throughout the story, some of whom (e.g. Cynthia and Wally) return from previous games.
371** ''[[VideoGame/PokemonUltraSunAndUltraMoon Ultra Sun and Ultra Moon]]'' keeps the above team battles and adds some more [=NPCs=] in the post game content that help you out. [[spoiler:During the Rainbow Rocket episode, Lillie teams up with you a few times acting as a CombatMedic with her Pokemon and Guzma joins you for one battle against some Rainbow Rocket grunts.]]
372** In ''[[VideoGame/PokemonLetsGoPikachuAndLetsGoEevee Let's Go, Pikachu! and Let's Go, Eevee!]]'', you and your rival team up against Archer and a Team Rocket grunt during Team Rocket's takeover of Silph Co.
373** In ''[[VideoGame/PokemonSwordAndShield Sword and Shield]]'', your rival, Hop, will team up with you in a few areas just as Hau did. Additionally, [[spoiler:[[OlympusMons Zacian and Zamazenta]]]] join the two of you in the battle against [[spoiler:Eternamax Eternatus]], which also serves as a taste of their power as [[spoiler:neither one can actually be captured until the postgame]].
374* Kai in ''VideoGame/PoPoLoCrois''. Just about everyone if you don't do the sidequests to get 'em, since it's a revolving door of party members in the game.
375* Any party member outside of the main eight of ''VideoGame/RakenzarnFrontierStory'' functions as such, only staying for a chapter. They usually boast unique classes and have levels higher than what you would have at that point, letting you breathe easy and grind a bit before you're left to deal with the real threat yourself. If you have a chance to equip them beforehand, they're nice enough to avert SoLongAndThanksForAllTheGear.
376* ''VideoGame/ReKuroi'': In the third level, Kaito has to escort Noelle, a non-wizard, out of the clock tower. She has a weak offensive skill and some skills to control enemy aggro, but doesn't gain EXP.
377* ''VideoGame/RealityMinds'': Kvena is playable for the first two dungeons, but stops participating in combat in the third because it would be hard to explain her presence to the new party member, Reffian.
378* ''VideoGame/RuinaFairyTaleOfTheForgottenRuins'': The fourth party slot is reserved for temporary party members and [[SummonMagic summonable allies]]. These party members usually leave the moment the player returns to town or another guest joins, though some of them can rejoin as normal party members. Significant guests include Dalim, who joins as an AI-controlled ally in the Dwarf Tower and [[spoiler:Chuna, who joins right before the FinalBoss in the rogue route.]]
379* The ''VideoGame/{{SaGa|RPG}}'' series:
380** ''VideoGame/FinalFantasyLegendII'' has Mr. S, Ki, Mask, Lynn (who joins briefly for two boss fights), Hana, Taro, [[spoiler:Isis]], and the protagonist's father will join twice. Most of them are around for only a dungeon or two, or a boss fight. The first three are over-powered (Ki is completely invincible to physical damage due to [[spoiler:the [[PlotCoupon Plot Coupons]], Magi]]), while Lynn is pathetically weak (which is even [[LampshadedTrope lampshaded]] in the game manual]]. Everyone else is only marginally more powerful, but your party at those points should be competent. The last party member, [[spoiler:Isis]], is an EleventhHourSuperpower, strong enough to take out the other half of the FinalBoss ''alone''.
381** ''VideoGame/FinalFantasyLegendIII'' actually had a space in your party that was reserved specifically for your Guest Star Party Members: Myron, Lara, Dion, Faye, and Borgin. Myron can one-shot many monsters for a while, while Lara is only around for a short period of time and is fairly weak. Faye starts out powerful, but by the time your party reaches the area where Xcalibur is, she's weak by comparison. Dion joins twice and is powerful, while Borgin is well-rounded. Borgin is notable in that he fights the FinalBoss with you and stays with you permanently.
382*** Of interest is that your CoolShip ''will'' assist in fights by opening fire at enemies you encounter while piloting it. It will also bombard the FinalBoss during the last phase of its fight.
383*** Unfortunately, while guest party members can equip items, they can then ''never unequip them''. Presumably this is to prevent the player from pulling an inverted SoLongAndThanksForAllTheGear when they're about to leave, but it not only means that they play that trope very straight, they also can be stuck with inferior equipment in many cases (for example, Borgin, as a magic user, really doesn't benefit much from wielding the Gungnir spear).
384*** One of the guests, Myron, actually appears briefly as a main character during the introduction -- and if you know what you're doing, you can take the opportunity to swipe his battle axe, which is [[DiscOneNuke a superior weapon to anything you can buy in the first town]]. When he joins immediately afterward as a guest, he has another copy of it.
385* Nicolai and the Mutant Apes in ''VideoGame/ShadowHeartsCovenant''. The Director's Cut version (never released overseas) has a VillainEpisode, where you control Nicolai, Veronica, and Lenny.
386* Almost every character in the official "Dead Man's Switch" scenario of ''VideoGame/ShadowrunReturns'', as characters generally are either among those you interact with between runs and those that you only use when you're on a run (who have no personality or interactions beyond being PlayerMooks). The few characters that fall into both categories generally only join you for one or two runs and are thus this: Only [[ActionGirl Coyote]] is repeatedly usable for most of the game. As characters bring their own private equipment on runs and you can't edit it in any way, there is practically no way to game the system.
387* ''VideoGame/ShinMegamiTenseiI'' and ''VideoGame/ShinMegamiTenseiII'' both have the demon beast Cerberus joining you early on for a brief time, only to leave after certain plot development. Both cases violate the "demons can't join you if your level is lower" rule (Kerberos is very overleveled compared to you), but with some justification - in the first case, he's made from fusing your dog and thus naturally loyal, and in the other he's on retainer from someone who's earned his respect already. [[spoiler:Both may also join you much later, when the level gap has been filled.]]
388* ''VideoGame/ShinMegamiTenseiIVApocalypse'' features several instances of this trope in one game, generally during its most climactic boss fights:
389** On the Law route, [[spoiler:Merkabah will help you during the final battle with Lucifer]]. On Chaos, [[spoiler:the inverse doesn't happen, as Merkabah is already dead once the route is triggered -- instead, the ending automatically starts]].
390** Hiroshi is a man who joins up with the party for one quest. Very unusually for the trope, you actually have more control over him than you do your actual party members, as you can tell him to buff you, attack, defend or pass. You can still have one of your usual partners alongside him, as he doesn't use the Partner slot.
391** At the very end of the game, [[spoiler:Flynn will follow you around and assist in battle]]. The exact details depend on the route; on Bonds, [[spoiler:he only helps in the final dungeon, but also helps outside of battle]]. On Massacre, [[spoiler:he doesn't help in the field, but he follows you everywhere]]. Furthermore, during the final battle, [[spoiler:he forms his own party to help fight YHVH. On Bonds, he's assisted by Jonathan, Walter, and Isabeau, while on Massacre, Satan is his only party member]].
392** The final battle of the Diamond Realm DLC has you teaming up with [[spoiler:all four of the protagonists from the past main numbered SMT games]], which the game implements in a unique way by giving you two alternating playable parties to fight with, much like [[spoiler:Flynn's party during the main game's final battle.]]
393* ''VideoGame/ShinMegamiTenseiV'' has Tao tagging along with you for all of Shinagawa, but only to heal your party after each encounter. She formally joins your party when you reach Taito [[spoiler:after her resurrection as Panagia]], but leaves again after the alignment lock, the timing of which depends on which ending you're going for. On the Law and Chaos endings, she stays with you until just before you fight [[spoiler:Lucifer]], but on the Neutral route she leaves immediately after you make your decision. However, if the conditions for the secret ending are met, she rejoins you after you defeat [[spoiler:Tsukuyomi]] and will stick around until the point she would normally leave.
394* ''VideoGame/SkiesOfArcadia'' uses an unusual variation. There are three main characters, and three other party members that constantly duck in and out of the story, replacing one another in your fourth party slot. Only at TheVeryDefinitelyFinalDungeon can you actually choose which one goes with you.
395* In ''VideoGame/SongSummoner: The Unsung Heroes'' for the iPod, you rescue 'Superstars', platinum ranked party members with only 2 deployment. (Deployment goes down every time you use a party member in battle, more if (s)he gets defeated. Zero deployment and you lose the party member FOREVER.) On top of this, YOU CAN'T GIVE THEM REWIND! (+1 Deployment)
396* In ''VideoGame/SonicChronicles'', Eggman joins the party for a while, and is capable of one-shotting robots if Tails is in the party as well. He breaks off near the second half of the game to make sure you can get back. [[spoiler: [[OpportunisticBastard He's actually taking over the world while you're gone due to the Twilight Cage's concept of time working differently.]]]]
397* Quite a few characters from ''VideoGame/StarOceanTheSecondStory'' could be considered this because they join your party before you decide whether or not you want to keep them, and you can choose not to recruit ''any'' character that could join your party besides whatever character you didn't choose to play as. Leon probably best fits this trope as he joins you temporarily no matter who you're playing as, but can only be recruited for good if Claude is your player character. And after you meet up with Ernest (you have to have Opera in your party first) you can choose to let them ''both'' go.
398* ''Franchise/SuperMarioBros'':
399** ''VideoGame/MarioAndLuigiDreamTeam'' sees the normally peaceful ExpositionFairy Prince Dreambert fight alongside Mario and Luigi when facing Antasma, although he does little more than heal them every few turns.
400** ''VideoGame/SuperPaperMario'' has a recurring villain who is encountered twice before joining the party seven-eighths of the way through the game, is overall stronger than Mario himself, spends less than 25% of the game with you before leaving after a DuelBoss battle, comes back in time for the final boss, and then is lost again to DemonicPossession in the ''final'' final battle. The character in question happens to be [[spoiler:Luigi. Yes, really]].
401* ''VideoGame/SwordOfPaladin'':
402** Alex is available during the tutorial section on the ship, but leaves to form his own squad afterwards. He briefly rejoins to help Nade defeat the Ogre in Bokka Village. He later gets his own playable section where he invades Armadias Castle. [[spoiler:When Nade loses his sword, Alex helps him defeat Charlemagne in order to upgrade the Paladin's powers. For his final playable appearance, he masters the Royal Gems in time to help Nade defeat former emperor Ragnarek.]]
403** During the mission in Zanga, the party is joined by Clifford, the knight commander in charge of the area.
404** Will temporarily joins as part of a joint operation between the Eagle Pirates and Nade's squad. Unlike most examples, he ends up becoming a permanent party member in Chapter 3.
405** Lancelot helps Nade and Alex defeat the Ogre, and he's significantly stronger than them both. [[spoiler:This is to set up the twist that he's actually the Ogre's boss.]]
406** In Arles Village, the two knights, Craig and Nanna, temporarily join the party for a mission to gather herbs. [[spoiler:Which makes it all the more shocking that they're actually luring the party into Lancelot's trap.]]
407** Once Nade becomes a Paladin and becomes aligned with Asgard, he'll often be accompanied by various Einherjar, with the most significant ones being Emilia and Theseus.
408** The merchant, Patrick, temporarily joins as part of the party's mission to gather medicinal flowers. Since he's a civilian, he has the Hide skill to avoid damage while the party handles the combat.
409** During Nade's Chapter 2 episode, he's joined by Captain Eagle.
410** During Lena's Chapter 2 episode, she's joined by Thalia, an assassin working for Queen Saber.
411** During Miguel's Chapter 2 episode, he's joined by Percival and Elaine, though they function as helpers for a puzzle rather than as combatants. [[spoiler:Later, the game has the player control these two in a boss battle against a vampire.]]
412** During Will's Chapter 2 episode, he's joined by Phoenix and Dantallion, [[spoiler:who are also being controlled by Red Rose's necromancy, though they get no lines due to having their wills completely removed.]]
413** At the start of Chapter 4, Nade teams up with [[spoiler:Anguis to take out a miasma-mutated queen bee. Anguis then tries to help him find a power source for Asgard's flotation device, but turns out to be the BigBad when he reveals that he's the source of the miasma.]]
414** During the Aggressor side story, the player takes control of Brigid [[spoiler:and the long lost Einherjar, Zash]].
415* Common in the ''VideoGame/TalesSeries'':
416** Chester Burklight in ''VideoGame/TalesOfPhantasia'' is a subverted example. He is in the party right from the start of the game, but leaves right after the first dungeon. He rejoins a bit later, also for one dungeon, and then leaves due to [[spoiler:accidentally being left out of TimeTravel spell]]. And then, ''much'' later, after the DiscOneFinalDungeon, he rejoins again. He's still on the same level as he was when he left, which is {{justified}}, because [[spoiler:the party returned into almost the same point in time after adventuring for weeks in the past]]. Various remakes has him catching up by training intensely while the party sleeps at inns.
417** Rondoline E. Effenberg plays this role in the X version of ''VideoGame/TalesOfPhantasia'', which was [[EmbeddedPrecursor included into]] ''Tales of Phantasia: Narikiri Dungeon X'', the remake of the sequel to the original ''Phantasia''. She joins sporadically throughout the story and helps them with her PurposelyOverpowered MagicKnight moveset. She then leaves permanently right before the final boss.
418** Leon Magnus from ''VideoGame/TalesOfDestiny'' is a party member for a good portion of the game, but leaves permanently after [[spoiler:he's forced to betray the party, fights them, and dies in the following cutscene]]. The remake still has it, but also adds "Narikiri dolls" - accessories that allow the player to turn any party member into a replica of him, sidestepping the problem of losing a character with a unique playstile.
419** Ras in ''VideoGame/TalesOfEternia'' joins the heroes after Keele leaves the party for a short time, and sticks with them for several dungeons. After that, however, [[spoiler:he reveals himself as the knight of the Empire, and intends to stop the party from going to Celestia because it might threaten the Empire]]. He remains a major character, but never rejoins the party.
420** ''VideoGame/TalesOfSymphonia'' has a variation. Kratos Aurion joins early on and sticks around until the DiscOneFinalDungeon, upon which he [[spoiler:reveals himself to be an [[OurAngelsAreDifferent Angel]], and gives you a HopelessBossBattle]]. Much later he rejoins for one more dungeon, and then leaves forever. However, there is a [[GuideDangIt convoluted]] way to have him rejoin again, but it requires giving the boot to [[spoiler:Zelos Wilder]], making this character a more long-lasting version of this trope.
421** ''VideoGame/TalesOfSymphoniaDawnOfTheNewWorld'':
422*** The game makes the entire old cast into this, having them join and leave very often, until they ''finally'' join for real in the last chapter. They also have fixed equipment and level, meaning that they will eventually fall behind main characters and their {{Mon}}s.
423*** Richter is a straighter example, who alternates between helping you and trying to kill you. He actually has a full, unique moveset, and is ''not'' completely busted, [[spoiler: which feels strange, when he turns out to be the final boss]].
424** Asch in ''VideoGame/TalesOfTheAbyss'', who, with the exception of several spells, is a carbon copy of the protagonist, and joins on two occasions[[note]]with the third one having no combat[[/note]] when the latter is not available. You can't change his equipment, which leaves him a bit underpowered in his second stint. There's also a [[GoodBadBugs bug]] that allows you to keep him, but doing so will [[GameBreakingBug break]] your NewGamePlus.
425** ''VideoGame/TalesOfVesperia'' has [[spoiler:Flynn Scifo]], who, in the original version, joins for a grand total of one battle. Remasters of the game expands his role, and gives him three more sections, as well as making him join permanently right before TheVeryDefinitelyFinalDungeon.
426** Richard in ''VideoGame/TalesOfGraces'' is a full party member in the [[ProlongedPrologue childhood arc]], but becomes this in the main game due to [[spoiler:being [[DemonicPossession possessed by Lambda]]]]. The remake promotes him to a full party member in the new "Lineage and Legacies" arc. He can also be used in the main story by transforming another party member into with a Narikiri doll.
427** ''VideoGame/TalesOfZestiria'':
428*** Alisha, heavily promoted as the female protagonist of the game, ended up being a guest, with her position being taken over by Rose. The story reveals that [[spoiler:since she has not enough resonance to percieve seraphim naturally, she unknowingly "borrows" it from Sorey, which impacts his health]]. After that Alisha leaves and [[PutOnABus almost completely disappears from the story]]. She ''does'' comes back for one dungeon and boss fight [[spoiler:against Maltran, her EvilMentor]], but leaves forever after that. Fans were ''not'' amused, and Alisha ended up becoming somewhat of a BaseBreakingCharacter.
429*** Another, much less controversial example, is [[spoiler:Dezel, who dies three quarters through the story in attempt to get his revenge against Symonne]]. The character is replaced by a MovesetClone, [[spoiler:Zaveid, who "[[ContrivedCoincidence just so happened]]" to be nearby and willing to join]].
430** In ''VideoGame/TalesOfBerseria'', Seres accompanies Velvet during the escape from Titania, but is not directly controlled by the player. She then leaves after [[spoiler:she's mortally wounded by a dragon, created by bad guys, and urges Velvet to [[CannibalismSuperpowers devour]] her to become stronger]].
431** In ''VideoGame/TalesOfArise'' Zephyr joins you after defeating the first boss for the remainder of the first region and the beginning of the second, after which [[spoiler:he's captured and tortured by Renans, who rule over the region, and when the party "[[NotQuiteSavedEnough saves]]" him, he's fatally stabbed by a PoisonedWeapon]].
432* ''VideoGame/TheiaTheCrimsonEclipse'': The game desginates certain characters as guests. Their weapons and skills cannot be upgraded, but the rest of their equipment is customizable. The game also warns that guests generally don't stay in the party in the long-term, though some guests also become fully playable if they have an in-story reason to join Seth.
433* In the Sega Genesis RPG ''VideoGame/{{Traysia}}'', soon after starting the game the main character acquires a party of three followers who will follow him through trials and tribulations for the rest of the game. Well, all except the [[FourIsDeath fourth party member]], [[spoiler:Floyd, who turns out to be TheMole after a few dungeons, and manages to end up as the BigBad by the end of the game.]]
434* In ''VideoGame/UnleashTheLight'', Bismuth joins the party in Demantoid's World to help them capture Demantoid's Prism with her Prism Containment Chest. [[spoiler:But after the team defeats Demantoid, Bismuth gets poofed while trying to block Demantoid's Prism beam long enough for Steven to retrieve the Chest. Bismuth's gemstone is then kept in your inventory as a Questy Thing, and you won't be able to add her to your party until she reforms, [[PlotlineDeath even if you have Rose's Tear to revive her]].]]
435* Counts for any party member you decide to sacrifice in the ''VideoGame/ValkyrieProfile'' games, with a few exceptions.
436** In the first game, all sacrificed party members become playable for B ending's final dungeon (unless they die in Valhalla) but by then, they're too far behind to be of any use to you. Freya, [[spoiler:Brahms and Lezard]] are more conventional examples of the trope, Freya only sticking around until the end of the first dungeon, while the characters in the spoiler are around for a single fight in the A Ending. All 3 can be permanently recruited in the post-game bonus dungeon. Meanwhile [[spoiler:Lucian]] plays with it, as they're a mandatory sacrifice for the A Ending, but in the B ending are no different from any other party member.
437** Due to ''[[VideoGame/ValkyrieProfileCovenantOfThePlume Covenant of the Plume]]'''s strategy elements, there are literal guest members who sometimes leave but most of the time join at the end of the chapter. Ancel also deserves a mention. He is a guest in the beginning but is sacrificed. In the A ending, he joins as a guest for the final battle.
438* ''VideoGame/VampireTheMasqueradeRedemption'' has this twice, once in the Dark Ages Era and once later in the modern era. In both cases, the guest becomes an enemy, and in both it's a case of SoLongAndThanksForAllTheGear.
439* ''VideoGame/Warhammer40000RogueTrader'': In the first combat you face, Kunrad Voigtvir will participate and constantly provide buffs; in the second combat, the ambush on the cathedral deck, Lord Captain Theodora von Valancius and Arch-Militant Mort join the fray and will largely handle the situation on their own while the game tutorializes about a few things. You won't have a chance to have them in the party again after this: Kunrad is TheMole and turns out to have orchestrated TheMutiny that takes up the JustifiedTutorial, while Theodora and Mort are murdered offscreen.
440* ''VideoGame/WildArms'' series:
441** ''VideoGame/WildArmsAlterCodeF'', the remake of the first game, allows Magdalen/[[InconsistentSpelling McDullen]] Harts and Mariel join the party for several short sections.
442** ''VideoGame/WildArms4'' has [[spoiler:Kresnik Ahtreide]] join you for about half of a dungeon, when one of party members is captured. You just know that the character won't stick for long, because they do not get any EXP, and you can't enter their GC Graph or edit skills. [[spoiler:He comes back in the final dungeon, when Jude is separated from the rest of the party, but appears to die just before they rejoin. Again, ''[[InferredSurvival appears]]''.]]
443* Both ''VideoGame/WhiteKnightChronicles'' and its sequel give you a variety of guest start party members who run the gamut in terms of usefulness in combat. Raus, a drunkard wagon driver is a [[TheLoad Load]] if there ever was one, as is Princess Cisna for the most part ([[RoyalsWhoActuallyDoSomething out of battle, however, she is a political machine]]). Amir is also kind of useless in combat too. Kara joins the party initially as a guest character on par with the other characters in terms of stats and equipment before joining up permanently. The second game gives you access to Miu, Scardigne, Archduke Dalam and Cyrus as guest characters. Miu is a competent fighter though technically 10 or 15 levels below the party in terms of gameplay numbers, same thing with Dalam, who has strong magic spells but lower stats than the pary. Scardigne and Cyrus, meanwhile, are practically player characters in terms of their strength. Scardigne eventually joins the party full time, [[spoiler:twice-over, actually when he's revealed to be Kara in disguise]].
444* In ''VideoGame/XenobladeChronicles1'':
445** Alvis and Mumkhar each fight in a grand total of one battle each as party members, and Dickson fights in two.
446** Fiora accompanies you for the first couple of hours before [[spoiler:being shish-kebabed by Metal Face]]. [[spoiler:Subverted when she is turned into a Face Mechon and ultimately rejoins the party.]]
447** At various points in the game, Otharon, Juju, Dickson, Alvis, Vanea, and [[spoiler:Shulk]] accompany your party as non-combatant guests.
448* ''VideoGame/XenobladeChronicles2'':
449** The first chapter places Jin, Malos, and Nia in your party. The former two are both higher leveled and much stronger then the latter of three, which makes it fairly apparent to a savvy player that they aren't going to be around for long.
450** Vandham is only part of your team for the duration of Chapter 3. He takes on the role of Rex's [[TheMentor mentor]], teaching him how to use the Anchor Shot art to topple enemies and regaling the youth with his philosophies about the nature of war and of the relationship between Drivers and Blades. This, coupled with the fact that he refuses to resonate with any other Blades than Roc, ought to ring some alarm bells. [[MentorOccupationalHazard Doesn't take a genius to see where that's going.]] The party does end up getting Roc's Core Crystal in the aftermath and he ends up resonating Rex himself later on, though.
451** During Chapter 8, [[spoiler:Jin becomes a temporary party member again for the trip through the Land of Morytha as Rex has been separated from his fellow Drivers, except this time you can actually control him if you want to see what has to say about doing quests, gathering items, or falling into bottomless pits.]]
452* ''VideoGame/XenobladeChronicles3'':
453** One of the main gimmicks of the entire game is that party members are divided up in “primary” party members, and “secondary” party members. The primary party members, of course, are the main characters, and the ones you control for the entire game. Secondary party members, better known as “Heroes,” are characters whom the player can have on the party at any time, but only one of them is allowed in the party at a time. This means that they’re unlikely to be in the party for very long before the player decides to use a different hero.
454** For the first half of the first chapter, the Kevesi trio have a fourth party member in the 10th term soldier, Mwamba, who provides a bit of extra firepower in battle and some tutorial advice. The fact that his equipment cannot be removed, he's [[YourDaysAreNumbered one month away from his homecoming]], and that the mission he helps the team is going to be [[OneLastJob his last mission]] before spending his last month as part of the salvage team just before leaving the party, can give many players an idea of [[{{Retirony}} what's going to happen to him]].
455** Ethel is recruited in Chapter 3 and accompanies you for a while, but is permanently removed from your hero roster shortly afterwards. [[spoiler:It's ultimately subverted when you find a reincarnation of her and age her up so she can rejoin you.]]
456** [[spoiler:Consul M switches bodies with Mio around the time of her fight with you in order to die in Mio's place, and is definitely in control by the subsequent fight against Consul N. You thus spend one fight controlling M, although it isn't made apparent until the beginning of the next chapter.]]
457* The ''VideoGame/{{Xenosaga}}'' trilogy has four of them. In ''Episode I'', Lt. Virgil, the trigger-happy, misanthropic, BloodKnight [[KnightInSourArmor in Sour Armour]], joins the party for a very brief time (like an hour if you're progressing really slow) at the beginning of the game [[spoiler:and then promptly dies. He comes back, though]]. ''Episode II'' takes a more unconventional route by having both the stone-faced badass Realian, Canaan, and the dopey UnfazedEveryman of the series, Allen, be ''technical'' guest character without them making any actual contributions to the gameplay. This is accomplished by having them appear as "co-pilots" of two of the party's HumongousMecha (Asher for Canaan, and Dinah for Allen). In ''Episode III'', Canaan and Allen are actually playable, however, and are joined by the other GeniusDitz of the series, Miyuki (our protagonist Shion being the original one).
458* In ''VideoGame/XMenLegends'' Professor Xavier is playable for one mission in the Astral Plane and is ridiculously overpowered, he gets taken out about three quarters in and Jean Grey and Emma Frost are forced to carry on without him; in the penultimate mission Xavier is used again (this time in the form of the "Astral Gladiator") for the boss fight against the Shadow King. Additionally, in one mission a computer controlled Havoc fights alongside Cyclops and Wolverine at the Weapon X ruins to rescue several hostage mutants. Later, he and Magneto fight alongside the X-Men party when Sentinels attack the mansion.
459[[/folder]]
460
461[[folder:Stealth-Based Games]]
462* ''VideoGame/MetalGearSolid2SonsOfLiberty'' has Solid Snake assisting Raiden twice in the Plant chapter. At the start of the fight against the harrier, he gives you a Stinger to use against the jet and he'll also toss you some rations and ammo if you run low. During the raid within Arsenal Gear, Snake will fight alongside you with an assault rifle or a pistol (depending on the difficulty) and will give you more ammo if you need it (he also lampshades how he has infinite ammo by pointing to his bandana, which is a CallBack to ''VideoGame/MetalGearSolid'' that gave you the same item in a NewGamePlus). Of course, the game ends if Snake is killed.
463* ''VideoGame/SplinterCellDoubleAgent'' (the version for [=PS2=] and [=GameCube=] era-consoles) gives you Hisham Hamza as a partner in the first mission. Other than a few team-up moves, he basically exists to shoot and kill any guards who threaten you before you've gotten the hang of the game's somewhat steep learning-curve of controls. Jamie Washington becomes this in the second mission, and will even take the only gun if you choose to not kill his nemesis in the yard fight that occurs. [[spoiler:When Hisham rejoins you much later in the game, he's unarmed, on death's door, and it's an EscortMission this time around]].
464[[/folder]]
465
466[[folder:Survival Horror]]
467* A few survival horror games, while not having a proper "party" do temporarily switch control from your main character to a secondary one. Frequently, this is explicitly so the secondary character can save the primary one who is in imminent danger. Examples include Rebecca from the first ''VideoGame/ResidentEvil1'' and Kaede from the first ''VideoGame/{{Onimusha|Warlords}}''. In a subversion, these guests are usually lacking in weapons and armor (Rebecca only has a handgun with no extra ammo) and can be a pain to play as.
468* ''Franchise/ResidentEvil'':
469** Depending on your actions in ''VideoGame/ResidentEvil1'' you can as Jill get Chris and Barry to help during the final battle, or as Chris get Jill helping you out. In the Platform/GameCube remake you can also get Richard to help you fight the snake, or either Barry or Wesker helping you face Lisa Trevor. [[spoiler:Be warned they ''can'' die in the snake and Lisa battles, and it will change the events of the game]].
470** ''VideoGame/ResidentEvil4'' has the [[HoldTheLine Cabin Fight]] where Luis helps you out. He can't die, has an upgraded [=Red9=] with unlimited ammo, and even throws you supplies if you run short. [[NonStandardGameOver Just don't shoot at him]].
471** ''VideoGame/ResidentEvil6'' has scenes where your actual partner will be separated from you and someone else will temporarily take their place. They are ''almost'' the same as your partner, just with a different load-out and you can't issue orders to them (They'll still bail you out if you call for help, though).
472[[/folder]]
473
474[[folder:Turn-Based Strategy]]
475* In the second to last mission in ''[[VideoGame/NintendoWars Advance Wars]]'' you get [[spoiler: Eagle]] helping you fight against [[spoiler: a clone of Andy and his army]]. You can't control the CO's units since they are under AI control. In the final mission, you get two other [=COs=] joining forces you with you to take down [[BigBad Sturm's]] army and you can control all three teams.
476* ''VideoGame/BattleForWesnoth'': Some campaign gives the player an unit that only lasts one or a few scenarios.
477** ''Sceptre of Fire'': Durstorn, the chief of Rugnur's clan, joins for the scenario 6 (and seeing as how he is a level 3 Dwarvish Lord, he is immediately useful). At the beginning of scenario 7, he promptly grabs an IdiotBall, runs out in the open trying to surrender, and is shot dead by the enemy elves (who also mocks him for thinking they would keep him alive).
478** ''The Rise of Wesnoth'' has the merman Lord Typhon who appears a scenario before Haldric's group is leaving the Green Isle, but he only sticks around during the ocean scenarios. Once Haldric's group reaches the Great Continent, Typhon leaves.
479** ''Under the Burning Suns'': Elyssa is encountered in the second scenario, journeys with the desert elves for several scenarios (given you manage to keep her alive), and then choose to stay behind with the dwarf/troll allies just before the elves are leaving their cave.
480* ''VideoGame/BerwickSaga'' has Vester, who's only playable in Chapter 12's main mission, after which he leaves. His stats for when you get to use him differs depending on if either Reese or Alvina recruit him (and in the latter case, if she gives him medicine from the local priest, resulting in him joining at full strength). Fortunately, SoLongAndThanksForAllTheGear does not apply to him, as any items that are placed into his inventory while he's playable will be returned by him at the end of the map.
481* Frequent in ''VideoGame/ChromaSquad'', as one of the Website/{{Kickstarter}} backer tiers allowed backers to design one. At least two to three times a season, one such character (usually either a fan of the show or a {{Sentai}} hero from a different franchise) will show up to support you for a single battle. They commonly have their own unique skills, do not need to transform, and are generally balanced against the season they show up.
482* ''VideoGame/{{Disgaea 2|CursedMemories}}'' has a fight against Laharl that is impossible to win, quite literally. [[EarnYourBadEnding Winning it ends with a bad ending]], but with his level 1200 stats, he's usually impossible to beat your first time through anyways. Once you lose the battle, you're handed level 2000 [[spoiler:True Rozalin]] whom you control and promptly decimates Laharl with nearly no effort. Once you see this power again, it's as a bonus fight in the [[EarnYourBadEnding Worst Ending]]. The game also features cellphones that can be used to summon additional characters (Kurtis, Axel, or a Prism Ranger) to fight alongside your team as [=NPCs=].
483* In ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'', Master Big Star and Salvatore join the group for the final battles, and stay until you beat the last boss. They rejoin permanently soon after in the first two post-story events, though.
484* ''[[VideoGame/ExtrapowerAttackOfDarkforce EXTRAPOWER Attack of Darkforce]]'': Happens now and again when allies to the player characters are officially joining a given fight. Most notably, the entire Hikari Warriors join up with Ruritia and the rest of the team to attack the Yami Clan and Yoberiade herself, letting the player experience their strengths and unique powers for themselves.
485* In ''VideoGame/FinalFantasyTactics'', there are often temporary members who assist your team in battle.
486** If they accompany your team for multiple battles, they will even show up in your party menus, and you can meddle with their equipment freely. This is even occasionally true of a plot-important character that does not show up in more than one battle, such as Alma or Princess Ovelia, who remains with the team for an extended period but prefers not to fight. However, unlike most other situations, these characters will not be under your control during battle. They will be labeled Guest, to distinguish them from the ones labeled Enemy, but both guests and enemies are computer-controlled. Enemies that are subjected to a successful Invite attempt by one of your Talk Skill users will qualify as a Guest until the battle is won, at which point you will have the option of making them team members or turning them away -- they are not allowed to continue being a Guest beyond the initial battle. Guest characters are the only ones exempt from the "three turns KO'ed=crystal or chest" rule, primarily because of [[WeCannotGoOnWithoutYou their importance to the plot]]. Once their role in the story is fulfilled, they can be recruited and at which point they can die for real at any time after that.
487** One interesting example is Gafgarion. [[spoiler:When he betrays the party, he does so after the mission begins and keeps the equipment, stats and class that you field him with. Before the mission, if you feel so inclined, you can pull a reverse WutaiTheft and turn him into a talentless, naked White Mage to make him a pushover]].
488** You also fight two battles with a permanently ''dead'' guest character.
489** Interestingly enough, the first time you meet Boco the Chocobo, he's a Guest for ''the Enemy''. (This was probably done so that Boco can't be killed and turned into a Crystal or [[HeelFaceTurn Invited]] into your party.)
490** ''VideoGame/FinalFantasyTacticsAdvance'' also had guest party members, but unlike the Playstation version, the guests here only aided you in the battle they appeared in and they never join the party afterward, nor can you fiddle with their items.
491** ''VideoGame/FinalFantasyTacticsA2'' has guest units again, but this time by the buttload and several are an EscortMission. There's even a few occasions where monsters are counted as guests! Some missions even has a few ''boss'' characters joining you in a few battles.
492* The ''Franchise/FireEmblem'' series has tons of these:
493** ''VideoGame/FireEmblemTheBlazingBlade'':
494*** In an example of a Guest Star Party Member being succeeded by an identical party member, Ninian and Nils, the Not-So-QuirkyBard. In the prologue, Nils the bard joins. Then during the main game, Ninian joins (with the stats that Nils had in the prologue) but then leaves. At the very end, Nils rejoins ''again'' with Ninian's stats and gear.
495*** Wallace joins you near the end of the prologue; he's a very powerful [[MightyGlacier Knight]] and CrutchCharacter for the enemies you face at the time. Not only is he available for only two chapters in the prologue, he also rejoins you late in the main game, when the enemies are tough enough to outclass Wallace easily. And that's assuming he even rejoins you at all; it's fairly easy to play well enough to skip that chapter. Fortunately, SoLongAndThanksForAllTheGear doesn't apply to him... any more than it applies to everyone else in the Prologue, at least.
496** ''VideoGame/FireEmblemTheSacredStones'' has [[spoiler:Orson]], who shows up in one Gaiden chapter before undergoing a FaceHeelTurn in his first appearance in the main story and showing up eight chapters later as a boss. He's a CrutchCharacter, so most people wouldn't really use him anyway, and he has [[SoLongAndThanksForAllTheGear good equipment.]] Which should of course be taken away immediately to keep him from counterattacking enemies, turning him into a nice little meat shield for his one appearance who, of course, you don't care about since if he's defeated, he'll just show up as an enemy again ''anyway''. And you can get him in back in your party post-game.
497** ''VideoGame/FireEmblemRadiantDawn'': [[spoiler:The Black Knight, who randomly appears for three chapters and is quite nearly invincible since his stats are all endgame-level.]]
498** ''VideoGame/FireEmblemFates'' has several due to the structure of the first 6 chapters which take place before the route split. Felicia with a male Avatar, Jakob with a female Avatar, ''Conquest'' and ''Revelation'' Gunter and Kaze, ''Conquest'' Azura, and ''Revelation'' Kaze, Rinkah, and Sakura all downplay this, temporarily joining your party, then leaving, then rejoining for good. In ''Birthright'' and ''Conquest'', you also take temporary control of all of your chosen royal siblings for one battle; they all rejoin later in their respective routes. ''Birthright'' Gunter, ''Conquest'' Takumi, Rinkah, and Sakura, and ''Revelation'' Scarlet all play this straight, joining you for a chapter or two and then leaving permanently.
499** ''VideoGame/FireEmblemThreeHouses:''
500*** At the beginning of the game, all three of the main lords in the game (Edelgard, Dimitri and Claude) are playable alongside player character Byleth as they work together to take down a group of bandits. Once an [[MilitaryAcademy Officers Academy]] house is chosen in the following chapter, both leaders of the other two houses will never be playable again, and cannot be recruited temporarily to assist with missions as other students can be.
501*** After the player chooses one of three school houses at Garreg Mach Monastery to teach, they gain full access to the students associated with their respective house to train and send into battles. You can temporarily recruit students from other houses to assist you in upcoming battles. They won’t gain any experience (aside from Support points) while they are with you and will appear as an allied unit, though they are very much under your control. This becomes {{subverted}} should you fulfill the student's recruitment requirements and accept their request to join your house to make them permanent additions.
502*** Certain paralogues, extra story chapters unrelated to the main story, will feature characters from different houses assisting in the battle. For example, one paralogue called "Rumored Nuptials," starring Ingrid, a Blue Lions student, also features Dorothea, from the Black Eagles house, as an allied character under the player's control (or vice versa, if you're a Black Eagle). Once more, {{subverted}} if you manage to recruit said character before doing the paralogue.
503*** One of the game's paths has an unavoidable case of this. [[spoiler:Specifically, the Black Eagles. If you side with Edelgard at the end of Chapter 11, Flayn will leave. If you don't, both Edelgard and Hubert will leave. Yes, the main Lord can potentially fall into this trope.]] This can be troublesome if you made any of these characters your Dancer, [[PermanentlyMissableContent as you'll never get another one.]]
504*** During the ''Cindered Shadows'' DLC campaign, you temporarily gain control of [[BigGood Aelfric]] for one chapter. The goal is to protect him from a band of marauders; fortunately, he can heal and do decent damage with his magic.
505** In ''VideoGame/FireEmblemWarriorsThreeHopes'':
506*** At the beginning of the game, you get to control all three of Edelgard, Dimitri, and Claude. After Chapter 1, you pick a house and the two you don't pick part ways with you.
507*** If you manage to [[spoiler:recruit Byleth and Jeralt, you get two extra chapters before the endgame that reveal who Arval truly is. The two lords you didn't side with join you as guests for Chapter 16 and leave for good at the end of the chapter.]]
508*** On a somewhat related note, in the Azure Gleam route, [[spoiler:if you fail to recruit Byleth and Jeralt, Rodrigue will be killed by Byleth as retaliation for Jeralt's death, meaning you only have so many chapters to play as him before then. Averted if you pursue the GoldenEnding as the requirement for it requires you to recruit them, ensuring Byleth has no reason to kill Rodrigue.]]
509* ''VideoGame/JeanneDArc'' for the PSP has several characters who join and then leave, but come back but the biggest example is [[spoiler:Liane, who poses as Jeanne and is burned at the stake in her place.]] But the second the longtime guest leaves, another identical party member replaces them.
510* In ''VideoGame/ShiningInTheDarkness'', if you rescue Gila, he joins the party as a non-player-controlled character who occasionally participates in battles, but leaves the party when they next spend a night at the Tavern.
511* ''VideoGame/SuperRobotWars'', though not so often at the beginning - instead, you are able to recruit a boss enemy, and their stats are often downgraded to party member level when they join. Sometimes, however, they keep full power until the next mission, which gives you the fun situation of having a character with 90,000 HP on the field. You are frequently given ally [=NPCs=] who tag along with you, mostly good-for-nothing redshirts, but occasionally someone will show up who's actually useful to you. Examples:
512** [[spoiler:Wodan Ymir,]] in Original Generation 2, whose arrival is much-needed, as you're fighting a near-final boss level character, your only character currently able to fight happens to be so badly damaged that doing anything with him other than just surviving is sheer suicide, and you can't send any reinforcements for several turns.
513** [[spoiler:Mekibos]], who you [[DefeatMeansFriendship defeated earlier]] and shows up to help fight against Wendolo. Unfortunately, he's defeated by a scripted plot event when Wendolo's mech's HP reaches 1/3rd of its max, and since he shows up when it's down to 2/3rds of its max HP, he effectively is only around for a third of the battle.
514* ''VideoGame/SuperRobotWarsX'': Provided the player has unlocked the requirements to recruit [[spoiler:Bizon, then Alfried in his Alsiel joins in the fight against Evgeni and leaves after finishing the stage. Meanwhile, Kittan sticks around for several stages before pulling off his HeroicSacrifice.]]
515* ''VideoGame/{{Super Robot Wars Z}}2'': [[Anime/ArmoredTrooperVOTOMS The Barcoff Squadron and Gregor, Baiman and Muza]] in [[https://www.youtube.com/watch?v=ayezowZz52U Scenario 39]].
516* ''VideoGame/SuperRobotWarsJudgment'': The [[Literature/FullMetalPanic Tuatha De Danann]] would be a regular member of the team if it could. Sadly, it is a [[CripplingOverspecialization simple submarine]], and thus can only fight with you on certain oceanic stages.
517** Advent never joins the party in ''VideoGame/{{Super Robot Wars Z}}3: Jigoku-Hen'', but he helps out a few times.
518* ''VideoGame/TacticsOgre'' has numerous guest star characters; due to branching storylines, some characters will just be guests on one path, whereas on another path they will be permanent additions to your army:
519** Lans, Warren, and Leonard are perhaps the best examples of this in ''VideoGame/TacticsOgre'', since nearly every guest party member is either recruited or killed in one path ''except'' them. Or you can make everyone be this by rejecting them when they offer to join. They are also the examples of when the trope overlaps with CrutchCharacter, as they do most if not all of the work for you when you have them on the map.
520** The pseudo-prequel Gaiden ''[[VideoGame/TacticsOgreTheKnightOfLodis The Knight of Lodis]]'' also has this, and the only true guest characters are Justin and Lara, later found as enemies. (You don't have to kill them as the only stage they appear on is a DefeatTheLeader stage.) Rictor and Orson are guests only in the "A" path, Cybil is a guest only in the "B" path, Eleanor and Ivanna ask to join regardless. (Shiven does not serve as a guest, being a spy)
521* ''[[VideoGame/TelepathRPG Telepath RPG Chapter 2]]'' has a mission where you must save a character named General Darkeye. Once you find him you are ambushed and he joins you in the fight but because he's weakened he has poor stats and only a basic psy attack so it's better to keep him in a corner during all the following combat so he doesn't die.
522* ''VideoGame/TriangleStrategy'' has several characters that only join you for a chapter and are AI-controlled.
523** In Chapter III, your guest star depends on which country you chose to travel to. In Aesfrost, it's Sycras, and in Hyzante, it's Exharme.
524** In Chapter IV, you fight alongside Dragan to help fend off the soldiers trying to kill him.
525** In Chapter VI, Maxwell battles alongside you to cover your escape from Glenbrook.
526** If you chose to protect the Rosellan village in Chapter XI, Jerrom helps out in the ensuing battle for the village.
527** Milo fights alongside the party in Chapters XIII and XIV. Unlike the other examples, she is fully controllable ''and'' can permanently join the party afterward, provided the player makes the right choice in the following chapter.
528[[/folder]]
529
530[[folder:Turn-Based Tactics]]
531* ''VideoGame/{{Odium}}'' has three permanent characters, as well as two other slots which keep changing as various allies join, depart or are killed off. You begin with the three guys, and by the final level of the game you're back to just these three again.
532* ZigZagged in ''VideoGame/XCom2'': although they're with you from the beginning, the ''Alien Hunters'' and ''Shen's Last Gift'' [=DLCs=] have one of the [=NPCs=] join the team on a mission. Whether or not they count as [[CrutchCharacter Crutch Characters]] depends on when you choose to do the missions. Also, the [[EleventhHourRanger final mission]], [[spoiler:which adds [[PlayerCharacter the Commander]] as a playable unit]].
533[[/folder]]
534
535[[folder:Wide Open Sandbox]]
536* ''VideoGame/SaintsRow'' has the homies system where you can summon characters to accompany you. Occasionally, there are some situations where you get unique homies you are unable to summon in free roam.
537** The Drug Trafficking activity in the first two games has the dealers set as homies, albeit they're the drivers, [[InvertedTrope in effect making you the homie]]. The first game had Tobias, Laura, and Marvin, while the second game had Luz and Richie. ''The Third'' averts this, as the dealers are Pierce and Zimos, who are summonable homies
538** ''VideoGame/SaintsRow1'' is unique in that [[EarlyInstallmentWeirdness the Saints themselves are guest star homies]] across various missions.[[note]]There's the semi-exception with [[spoiler:Zombie Lin, but Lin never appears as a homie when alive]].[[/note]] The Vice Kings storyline also has [[spoiler:Benjamin King as a guest star homie once he is overthrown, and assists in the last few Vice Kings missions.]]
539** ''VideoGame/SaintsRow2'' has several non-Saints homies that assist in several missions. Such include Donnie for "Reunion Tour", [[EnemyMine Maero]] for "First Impressions", Laura for "File in the Cake", and Jessica for "Bank Error in Your Favor" for the [[{{Bowdlerise}} censored versions]] of the game due to the removal of human shields. The only Saint homies that don't stay with you are [[spoiler:Carlos and Julius, as the former dies in "Red Asphalt" and the latter dies at the end of "Revelation".]] The FUZZ activity also has the camera man as a guest star homie, who helps gather footage of your [[PoliceBrutality civil service]].
540** ''VideoGame/SaintsRowTheThird'' has less guest star homies than previous games. The only guest star homie in the base game is [[spoiler:Johnny Gat, due to seemingly dying in "I'm Free - Free Falling".]] Jimmy Torbitson also appears as a guest star homie for several missions in the ''The Trouble With Clones'' DLC.
541** ''VideoGame/SaintsRowIV'' has only ''one'' guest star homie, with Nyte Blade assisting you in Matt's loyalty mission "Nytefall". However, the ''Enter the Dominatrix'' DLC has him as a unlockable homie, averting this trope.
542** ''VideoGame/SaintsRow2022'' has a ''temporary summonable'' homie in the form of [[spoiler:the Nauhualli]], who betrays you in the endgame and perishes.
543[[/folder]]
544----
545!Non-Video Game Examples:
546
547[[folder:Anime and Manga]]
548* ''Manga/DragonQuestTheAdventureOfDai'': Princess Leona is good friends with the Disciples of Avan, and [[WhiteMagicianGirl better at healing than the group healer]], but she's busy enough [[PoliticallyActivePrincess running her country and forging alliances against the Dark Army]] that she usually only fights alongside them when the battle ends up on her doorstep. This changes towards the end of the series, where she officially inherits [[{{Mentor}} Avan]]'s position as the heroes' BigGood - joining the group in their final assault on [[TheVeryDefinitelyFinalDungeon Vearn Castle]] not for her healing abilities (which are less needed at this point) but to act as a SupportingLeader.
549* ''Manga/FrierenBeyondJourneysEnd'': Midway through the first season, Frieren and her party visit a village where they end up being joined by Sein who wants to heed his CallToAdventure at the behest of his brother. He hangs around with them for a few episodes before eventually parting ways with them shortly before they decide to visit Auberst. In addition, Eisen also briefly qualifies as he does tag along with Frieren and Fern when they come visit him, but eventually chooses to stay home rather than rejoin his old party member and her apprentice on their journey.
550* ''Manga/OnePiece'':
551** [[ThoseTwoGuys Johnny and Yosaku]] show up right before the Baratie arc and leave at the end of the Arlong arc.
552** Nefertari Vivi joins the crew for the entire Baroque Works saga, and serves as the catalyst to both bring the Straw Hats into conflict with Crocodile and get them involved in the civil war in Alabasta, her home country. However, Vivi is a unique variation of this trope, because despite her leaving the main Straw Hats after Alabasta, she remains considered one of them by everyone who knows she was on the crew, including WordOfGod, which is an honour not given to anyone before or since.
553** After allying with the Straw Hats to take down Doflamingo in Punk Hazard, [[SpaceMaster Law]] joins them for the rest of the Dressrosa saga, as well as the Wano arc after reuniting with his own crew.
554** Likewise, [[{{Samurai}} Kin'emon]], a samurai from Wano, and his [[spoiler:not really]] son Momonosuke join the Straw Hats during Punk Hazard, Dressrosa and Wano.
555** Carrot, a rabbit [[BeastMan Mink]], is introduced in the Zou arc and joins the Straw Hats during the subsequent Whole Cake Island and Wano arcs.
556** Yamato is another close ally of the Straw Hats during the Wano arc, to the point that the end of the arc teases them becoming a full-on SixthRanger, who to ultimately pass on joining them for the time being.
557* ''Anime/ZombieLandSaga'': Episode 7 of Revenge introduces Maimai, who Kotaro thought he had accidentally killed in a bathhouse incident. She was agreed to become a member of franchouchou to make sure the secret's safe. After having a chat with Sakura, she decides to leave the group right after her first concert, but [[SecretKeeper promises the zombies' secret is safe with her.]]
558[[/folder]]
559
560[[folder:Comic Books]]
561* ''ComicBook/WonderWoman'':
562** The Byrne run on ''ComicBook/WonderWoman1987'' was especially heavy on guest-stars that typically had nothing to do with Wonder Woman (and everything to do with Byrne's idol Creator/JackKirby). For almost half the run, in fact, the usual "Wonder Woman created by William Moulton Marston" tag sat right across from a "[[ComicBook/{{Etrigan}} The Demon]] created by Jack Kirby" tag.
563** ''ComicBook/WonderWoman2006'': In the "Birds of Paradise" arc ComicBook/BlackCanary joins the book as a temporary {{deuteragonist}}.
564[[/folder]]
565
566[[folder:Fan Works]]
567* Connor Hawke of ComicBook/GreenArrow turns up for a few chapters of ''Fanfic/AngelOfTheBat: Times of Heresy''. He gives some combat assistance against Star City's own Constantine Drakon and offers some Buddhist perspective to Cassandra when he sees she's struggling with her faith.
568* In the second installment of ''Fanfic/CobysChoice'', [[spoiler:Kaku, outed as a [=CP9=] defector, forced to leave his life as a Water 7 shipwright, and lacking any better options]], tags along with Merry when she goes to Sabaody for the Straw Hat Pirates reunion. While he repeatedly insists that he's only a temporary tag-along, he's still with the crew as of the Punk Hazard arc and only time will tell if he ends up joining for good.
569* Each consecutive story in ''Fanfic/TheDisneyChronicles'' features at least one or more of them other than the Mane 6 and Spike themselves.
570* In ''Fanfic/{{Eleutherophobia}}: How I Live Now'', Toby joins the Animorphs (and Tom) on their mission to deal with the last human-controllers.
571* ''Fanfic/ImNobody'': [[spoiler:Della Duck]] decides to join the Normandy crew on their hunt for Saren until she manages to fix her ship to go back home, which she does as soon as it's complete.
572%% * The Doom Patrol becomes this for the run of ''Fanfic/TheEndOfEnds''.
573* ''Fanfic/TheMountainAndTheWolf'' has Harald Hammerstorm (a Chaos warrior so good at killing undead he can make them feel fear) show up during a raid on a Tomb King's obelisk. In exchange for his help, the Wolf drops him off at the Crater of the Waking Dead, a ForeverWar between two skeletal armies.
574* ''FanFic/TalesOfKittyWhiskersAndLadybug'': The newly hired Athena Cykes from Wright Anything Agency is temporarily given the Fox Miraculous to help Ladybug (Apollo) and Kitty-Whiskers (Trucy) fight off an akuma.
575* ''Fanfic/VowOfNudity'': Several stories include a character who joins Haara for just a single adventure. The two most straightforward examples are Walburt the Barbarian and Fiora the Forest Witch.
576[[/folder]]
577
578[[folder:Music]]
579* In 2018, Music/{{Gorillaz}} bassist Murdoc Niccals was incarcerated, meaning the band had to get a temporary bassist to fill in for him. His replacement? [[WesternAnimation/ThePowerpuffGirls1998 Ace Copular, leader of the Gangreen Gang.]]
580* Music/KingCrimson: ''Music/InTheWakeOfPoseidon'' features Greg Lake as vocalist on most of the sung tracks with the sole exception of "Cadence and Cascade", which was sung by Gordon Haskell. The latter would later provide lead vocals on the following album, ''Lizard'', before quitting due to CreativeDifferences with Robert Fripp.
581[[/folder]]
582
583[[folder:Podcasts]]
584* ''Podcast/TheAdventureZone'':
585** The third episode of ''Podcast/TheAdventureZoneKNights'' sees the [[Creator/McElroyBrothers McElroys]] joined by good family friend Creator/LinManuelMiranda, who plays human bard Atreyus Kannon.
586** In the second live episode of ''Podcast/TheAdventureZoneBalance'', Tres Horny Boys are forced to do a four-person team-building exercise. The fourth member of their team is half-orc bard Brad Bradson, played by Stuart Wellington of ''Podcast/TheFlopHouse''.
587** Most arcs in ''Balance'' also have an NPC who is generally more competent than the boys join them to help them with what they're trying to do, such as [[KidDetective Angus McDonald]] in the ''Murder on the Rockport Limited'' arc, or [[ActionGirl Lieutenant Hurley]] in ''Petals to the Metal''. This trend is done after ''The Crystal Kingdom'', as by that point they've got the game figured out.
588* In ''Podcast/{{Jemjammer}}'', Grak the Dohwar (penguin-person) joins the group in the episode "Port Meridian", played by [[https://twitter.com/vriosart Rio]].
589* ''Podcast/CoolKidsTable'' has a few guests alongside the regular players, such as David as Caleb in ''Firefly: : The Zelda Chronicles'', Matt as himself in ''Hogwarts: The New Class'', and Cassidy as Sid in ''Podcast/{{Sequinox}}''.
590* ''Podcat/PokemonWorldTourUnited'' has also had plenty, since one of their patreon rewards is to be a gym leader or trial captain. So far there's been Sky Ertl (as Kent), Matt Hoadley (as Trey), Annie and Jonathan Craton (as Calico and Aegean), and Riley Hopkins (as Emma). There's also regular recurring cast member Shannon (as Cira), and an appearance by Jake's brother Scott (as Raleigh).
591[[/folder]]
592
593[[folder:Tabletop Games]]
594* ''TabletopGame/InterstitialOurHeartsIntertwined'' has The Chosen playbook, which aims to replicate this in tabletop form by letting you play a character native to the current world, and change which character they're playing each time the world changes.
595[[/folder]]
596
597[[folder:Theatre]]
598* In the ''Theatre/MrsHawking'' play series: Clara briefly helps with the investigation in ''[[https://vimeo.com/201477887 Base Instruments]]'' (and even provides some important clues and perspectives). She rejoins Team Hawking in ''Mrs. Frost'', largely because the titular villain has kidnapped her husband. The same play also sees Arthur assisting the group more actively via Mary, and [[spoiler:Madam Malaika]] as well.
599[[/folder]]
600
601[[folder:Web Animation]]
602* ''WebAnimation/KnightsOfTheOldRepublicCinematicUniverse'': Unlike in the [[VideoGame/KnightsOfTheOldRepublicIITheSithLords source material]], Canderous Ordo, now the new Mandalore, joins Meetra Surik's party only for the duration of ''Episode V: Hunger for the Force''. Once he has gathered the dispersed Mandalorian clans and helped win the Onderon Civil War as well as the Battle of Telos IV, he returns to Dxun to lead his people.
603[[/folder]]
604
605[[folder:Webcomics]]
606* Spoofed in ''Webcomic/{{Adventurers}}'', where a character joins and after being given gold armour, [[SoLongAndThanksForAllTheGear leaves]].
607* In ''Webcomic/TheOrderOfTheStick'':
608** [[ShockAndAwe Celia]] plays this role for Haley and Belkar after the party splits. She can't help them much in combat, though, as she's an ActualPacifist.
609** Miko also temporarily joins the group, mostly because Roy is thinking with his [[UnusualEuphemism Trouser Titan]], until the rest of the party (except Durkon) confronts her, refuses to put up with her any longer, and she [[{{Railroading}} beats up everyone except Durkon]].
610** [[spoiler:Minrah Shaleshoe and [[TheBusCameBack Hilgya Firehelm]]]] become this in Book 6 when the rest of the Order must chase down and kill [[spoiler:a vampirized Durkon]]. After their goal is said and done, [[spoiler:Minrah joins the Order as an EleventhHourRanger.]]
611* In ''Webcomic/RPGWorld'', the group fights Galgarion at one point, with (former) Evil Soldier #347 joining them as a "computer-controlled" ally for the battle after Galgarion [[spoiler:killed his wife and kids]]. Dialogue later suggests he could have been "[[SecretCharacter unlockable]]" but the party was already "Full".
612* In ''Webcomic/RustyAndCo'', a Five Races ActionGirl adventures with the core team every "level" (story). For the first three levels it was merely meet the Action Girl and adventure with her, but after that their roles started to grow more complex.
613* In ''Webcomic/YokokasQuest'', the high level Azha and his {{familiar}} Misha appear in [[https://yokokasquest.com/comic/chapter-3-status-screen/ Yokoka's party's status screen]] even though they only travelled together for that single chapter.
614[[/folder]]
615
616[[folder:Web Original]]
617* ''WebVideo/CriticalRole'' features quite a few of these, as famous voice actors and other nerds beyond the main party join for an episode or two to help the main party accomplish a short-term goal.
618** Joining Vox Machina, we have Lyra (Creator/FeliciaDay) the human wizard, Zahra (Creator/MaryElizabethMcGlynn) the tiefling warlock, Thorbir (Creator/WilWheaton) the dwarven fighter, and Kashaw (Creator/WillFriedle) the human cleric, who are assigned to aid the party during the Slayer's Take trial. Other guest stars include Lillith (Kit Buss) the tiefling wizard who helps deal with the Briarwoods, Garthok (Jason Charles Miller) the half-orc rogue member of the Clasp who pulls an EnemyMine to help Vox Machina find survivors in the wake of the Chroma Conclave attack, Gern (Chris Hardwick) the dragonborn wizard who guides the group through Pyra, Shale (Christopher Perkins) the goliath fighter who helps in the fight against Umbrasyl, Kerrek (Creator/PatrickRothfuss) the human paladin who fights in the siege of Emon and [[spoiler:helps take down Raishan]], Tova (Creator/NDStevenson) the dwarven bloodhunter who travels with Vox Machina through the city of Dis, Lionel (Jon Heder) the half-orc barbarian who works for [[spoiler:Scanlan]], Sprigg (Creator/DarinDePaul) the gnomish rogue living in a booby-trapped cottage in the middle of nowhere, and Arkhan (Creator/JoeManganiello) the dragonborn paladin/barbarian who aids in the fight against [[spoiler:Vecna]].
619** Joining the Mighty Nein, we have Shakäste (Creator/KharyPayton) the human cleric who helps the Nein clear out a gnoll-infested mine [[spoiler:and later helps defeat the Iron Shepherds]], Calianna (Mark Hulmes) the half-elven sorcerer who is looking for a mysterious artifact in the Labenda Swamp, Keg (Creator/AshlyBurch) the dwarven fighter and Nila (Creator/SumaleeMontano) the firbolg druid who help save several members of the Nein from the Iron Shepherds, Twiggy (Creator/DeborahAnnWoll) the gnomish rogue who accidentally gets the Nein trapped in her HappyFunBall, Spurt (Chris Perkins) the kobold inventor who is there for 20 minutes before getting flattened by a fire giant, and Reani (Mica Burton) the aasimar druid who joins the Nein in their search for a white dragon. "The Mighty Nein Reunion: Echoes of the Solstice" post-campaign one-shot also added Rab "Aggy" Agg (Daniel Sloss), the dwarf monk investigator of the Cobalt Soul who helps the Nein investigate a possible breach in the Rexxentrum Archive.
620** Bell Hells is a particularly interesting example, since one of their founding members was a guest star -- Dorian Storm (Creator/RobbieDaymond), the genasi bard who first appeared in ''WebVideo/CriticalRoleExandriaUnlimited'' with main party members Orym and Fearne. Beyond that, we have Dusk (Creator/ErikaIshii), the elf paladin who was saved by Bells Hells and has a connection to Fearne's long-lost parents [[spoiler: who turns out to actually be [[SixthRangerTraitor Yu]], a changeling warlock/paladin]]. In the wake of [[spoiler: the Apogee Solstice]] splitting the party, Deanna (Aabria Iyengar), the gnome cleric and a former flame of Chetney's, and her companion FRIDA (Creator/ChristianNavarro), the aeormaton fighter / rogue / cleric with a similar background to FCG, run into half of the party near Uthodurn, while Deni$e Bembachula (Creator/AimeeCarrero), the dwarf rogue / barbarian whose ex-fiance happens to be Orym's friend Dariax, Prism Grimpoppy (Emily Axford), the elven wizard apprentice from the Cobalt Soul, and Bor'Dor Dog'Son (Creator/UtkarshAmbudkar), the half-elf sorcerer shepherd who has no idea how he got magic [[spoiler: but is actually part of the enemy Ruby Vanguard]], are teleported to Issylra with the other half.
621** Additionally, [=NPCs=] sometimes travel with the party.
622*** Vox Machina is joined by halfling paladin Lady Kima of Vord and the mind flayer arcanist Clarota during the Underdark arc. Lady Kima, in particular, has traveled with Vox Machina often enough that they consider her an honorary member.
623*** The Mighty Nein are joined by their ship's crew during their voyages out into the ocean, most notably the tortle bard Orly, who takes up the role of navigator. Later, they befriend the drow wizard Essek Thelyss, who serves as their primary contact in Xhorhas and later joins the Nein for their trip to Aeor. By this time, Essek's involvement with the party is so significant that all of them consider him an official member of the Mighty Nein.
624*** Bells Hells are temporarily joined by [[PreviousPlayerCharacterCameo Vox Machina member Keyleth of the Air Ashari]], the half-elven druid, who travels with the group to Yios, and human wizard Allura Vysoren (recurring NPC in Vox Machina and Mighty Nein), who chaperones the group to Fearne's home in the Feywild.
625* An In-Universe example in ''Literature/TheLeapfroggedConsoleWars'', the expansion to the Ultra Nintendo game ''VideoGame/FinalFantasyVII'' titled ''Espers and Madness'' has [[VideoGame/FinalFantasyVI Kefka]] join the party only to betray them later.
626* LetsPlay/PartyCrashers:
627** In "[[https://www.youtube.com/watch?v=TSnKelVlc2E Mario Party but it's Simon Says]]" and "[[https://www.youtube.com/watch?v=J1usjQ_s2vw Mario Party but it's Simon Says 2]]", [[https://www.youtube.com/@Peanut_SSBU Peanut]] takes Sophist's place as the fourth player due to the latter taking the role of Simon.
628** In Vernias' "''NEW'' VideoGame/SuperSmashBros Characters" [[https://www.youtube.com/playlist?list=PLeoTnnMHjKGqws1_cXeUPUt3OwgL_RpNr series]], [[https://www.youtube.com/@HarryBook HarryBook]] takes Nick's place due to the latter not being nearly as experienced with Photoshop as the others.

632* ''Franchise/ScoobyDoo'':
633** ''WesternAnimation/TheNewScoobyDooMovies'' and ''WesternAnimation/ScoobyDooAndGuessWho'' have this as their entire conceit, as one different living, late or fictional celebrity guest (sometimes more) helps Mystery Inc. in each case.
634** ''WesternAnimation/WhatsNewScoobyDoo'' is noteworthy for having Music/SimplePlan (who performed the theme song for this iteration) help the gang with a case in one episode.
635** ''WesternAnimation/ScoobyDooMysteryIncorporated'' has a particularly unusual case of celebrity involvement by having Creator/HarlanEllison himself assist the gang sometimes, to the point of [[spoiler:playing a vital role in the finale and [[LegacyCharacter taking up the mantle of Mr. E]]]].
636** The WesternAnimation/ScoobyDooDirectToVideoFilmSeries occasionally has special guest celebrities or characters involved with a case (much like the series mentioned above). In particular, entries featuring the [[Wrestling/{{WWE}} WWE organization]] and ''WesternAnimation/BatmanTheBraveAndTheBold'' cast are ''PACKED'' with guests.
