In an RPG, the opposite of an Optional Party Member
. That is, someone who you have
to have in your group, usually due to plot reasons. Depending on the story, they may leave after their work is done, taking with them everything they had
, or they may stick around with your Ragtag Bunch of Misfits
A slightly less annoying version is requiring certain party members to raise specific Event Flags
. You don't have
to put Bob into the party so he can unlock the door to the underground base... unless you want 100% Completion
This can also be But Thou Must
, if the game appears
to give you a choice, but then forces you to use the characters it wants you to anyway. If it's the main protagonist that's forced to be in your party at all times (which is almost always the case anyways), that's Can't Drop the Hero
- In Maniac Mansion, The Hero Dave is required to participate in the rescue, while you can choose two other characters to use at the start of the game.
- This happens frequently in the Pokemon Mystery Dungeon series, particularly in the games after the first. You're often denied the ability to bring any party members of your own choosing in the story dungeons, either having to manage with just you and your partner or being forced to take along a NPC, as well (Who annoyingly, need to survive through the dungeon and cannot be issued commands like normal party members, which can lead to losses via Artificial Stupidity).
- Gates To Infinity is more merciful about this, as the Pokemon who you're forced to take are either an official part of your team (Meaning you can level them up and customize them to your liking beforehand) or are extremely overpowered, plus it no longer matters if they get KO'd and you can issue them orders.
- Dawn of War II has Can't Drop the Hero in full effect. The first expansion Chaos Rising, plays with this trope. While the Force Commander is still mandatory, certain squads will gain corruption if forced to stay behind for certain missions (though you are notified of this before you launch). The second expansion, Retribution does away with this.
- Various characters during the seven heroes' games in SaGa Frontier have to join your party just to advance the plot. Others, like Gen and Fuse are required to do certain quests.
- A few of the stars in Suikoden games get thrown into your party for plot. Luckily, due to the game's levelling system, even if they're weak when you get them, they catch up fairly quickly. These are also the characters that tend to get the most characterization.
- The first game was probably the worst about this, to the point where half of your six-person party was predetermined for the last stretch of the plot, right up to the final boss. By contrast, Suikoden V included four 'extra' party slots (for a total of ten) where you could put non-combatants and spare members. So if somebody was forced into your party for plot reasons and you didn't care to use them/they were way too underleveled, you could just stick them in there and drag them along without worrying about dead weight.
- Your party is perpetually altering itself in Final Fantasy IV, but it's always doing so at the story's discretion.
- Final Fantasy VI is an odd case in that this happens frequently in the first half of the game (such as with Banon's Escort Mission, or Locke and Celes being mandatory for the opera house storyline), but in the second half, almost nobody is technically required except for a few characters. You could go straight to the final dungeon with only three characters if you wanted to.
- A more minor example of the Event Flag version of this trope occurs in cutscenes after you can begin swapping party members in and out of your group. While dialogue is largely the same regardless of who is with you, particular characters will get lines attributed to them specifically. If that character is not in your group the line will simply have quotation marks around it and no named speaker
- Final Fantasy VII loves this trope; at various points in the game, one character or another is required to be in your party to advance the plot, whether you like it or not.
- Barret forces himself into the party as they investigate who is framing him.
- Red XIII is forced onto you when you explore the caves in Cosmo Canyon as he learns about his father.
- Aerith is forced into your party as you explore the Temple of the Ancients so she can understand herself and her ancestors. Meta-explanation: it's required because she's about to leave the party. And no, you are not getting her back. Can also be a Player Punch if you were trying to get her together with Cloud.
- Done once again in the Whirlwind Maze where Tifa forces herself into your active party so she can see Sephiroth defeated once and for all. However, the game forces Tifa to join you so that she can see that Cloud's memories of the Nibelheim incident are fragmented and made up, forcing her to spill the beans about what really happened. What makes this example particularly frustrating is that she gets shoehorned into the party right before a boss fight, quickly turning her into The Load if you haven't been training her.
- When Shinra attempts to use the rocket in Rocket Town, Cid forces himself into your party so he can personally kick Shinra's ass.
- Cid also becomes the lead character for a little while when Cloud is forced out of the group. Hope you've given him some decent levels and gear...
- In Final Fantasy VIII, during the last portion of Disc 1, you are forced to use the split up teams of Squall, Irvine, and (later on) Rinoa as well as Quistis, Zell, and Selphie. On Disc 2, when visiting the now under siege Balamb, Squall must have Zell in the party.
- Final Fantasy IX does this constantly until Disc 3. It also does the inverse, having characters just randomly walk away so that you can't add them to the party.
- In Final Fantasy X, while you can usually switch characters at any time, there are a few parts where you have to fight underwater - and that means only Tidus, Wakka and Rikku can be in your party for those parts, since they're the only ones who know how to fight in the water.
- You can recruit/remove Wakka from the Besaid Aurochs team, but never Tidus (you don't have to play him, but he takes up a slot).
- Final Fantasy XIII is an absurd case. You can't switch party at all until you reach the Ark. Read: Chapter 11, around 18+ hour of gameplay. Even when the group's shown to be together, you can't just switch anybody out until then. The game plays this straight at the conclusion of Chapter 10, though, as you can have anyone in the party, as long as Lightning is the leader.
- Final Fantasy XIV has an unusual case of the trope at the end of the 2.5 storyline. Midgardsormr, a legendary and ancient dragon whom you defeat at one point, not only takes away your special ability that the Mothercrystal blessed you with, but uses some of that power to construct himself a temporary body and forces himself into your company as a minion/pet. Unlike other minions, Midgardsormr is NOT optional and he automatically gets added to your minion list whether you want him to or not. Said dragon will also pop up during certain cut scenes to give his quips on what the current situation is and you can't stop him from doing so. To drive the point home further. Floating/flying minions will sometimes land on your head/shoulder and fly off if you move. Midgardsormr, if you have him out, will perch on your shoulder and will only get off when he feels like it as he sticks to you like glue. That dragon won't be leaving anytime soon.
- Happens quite a bit in Sonic Chronicles, whenever you must split into teams. Usually, some choices are already pre-selected for you, which can be a pain as it locks out certain combination attacks.
- One especially annoying example is Omega, who is Lost Forever if you don't find him in Eggman's City. Better hope you remembered to bring Shadow or Rouge along if you don't want him to try and murder Eggman.
- The .hack games would occasionally require you to use specific teams for story events. When this happened, you could bet you were going to see an FMV before the dungeon was out. There were also side-dungeons which your party members invited you to, thus requiring you to use that particular person. At one point this results in an inadvertent Two-Timer Date when Kite is invited to the same dungeon by both Black Rose and Terajima Ryoko.
- The sequel pretty much forces at least one member for nearly every story dungeon. Likewise you're team for the Arena story battles are always Haseo/Atoli/Silabus for Vol 1, Haseo/Atoli/Alkaid (Haseo/Kuhn/Endrance for the finale) in Vol 2 and Haseo/Atoli/Kuhn for Vol 3. And whenever AIDA is confirmed in a dungeon you can only take someone who has an Avatar there.
- In Planescape: Torment, Annah is necessary to progress into the Lower Ward. Unless you kill her, then the game opens another path for you.
- In Tales of Symphonia, Collette is required in all of the boss fights at the end of Sylvarant's temples, while Sheena is required for all summon seals. Also, in order to get the location information for monsters into your Monster Book, you need to use the Magic Lens with Raine, not any of the other characters. Raine is also required for the Windmaster boss fight, because she is participating in the ritual, and Lloyd is required for the third battle with Yggdrasill, the third battle with Kratos and the battle with Origin.
- Mulan (as Ping), Auron, Jack Sparrow, and Simba at certain story points in Kingdom Hearts II. Only the third of these has an "excuse" for his requirement.
- Also in the same game, during the last boss battle in Space Paranoids, the party requires Tron to be active during the battle with the MCPnote , even though he didn't get the (!) that the previously mentioned got when they were required. Fortunately, since party members can be switched mid-combat, it's not much of an issue.
- During the final battle against Xemnas, Riku will be Sora's only remaining party member after the first stage. Like with Jack Sparrow before, it's game over if Riku's HP hits zero.
- In the first game, Peter Pan is required to be active to fight the Phantom in Neverland.
- The Hierophant/Lovers full moon in Persona 3 requires you to bring Yukari (because your party was fixed last time and did not include her) so you can fall into The Lovers's mind control. This is slightly more lenient in Portable for the heroine — you'll need a full party, which ensures that you'll have to bring at least one of the guys.
- In "The Answer", your party will consist solely of Aigis and Metis for the 2-on-2 party battles before the final door.
- Knights of the Old Republic gives you numerous quests that cannot be completed without a certain party member. You get forced to take Carth when you first enter Taris, you have to have Mission to get into the Vulkar base, T3-M4 is required to get into the Sith base, you need HK-47 to complete the light-side track with the Sand People on Tantooine, you need Bastilla for the beginning of Dantooine, etc.
- And railroads you entirely on the Leviathan level, by locking you with Carth and Bastila. Of course, because of certain story events, the whole thing wouldn't work without them. The Brotherhood of Shadow mod also forces this in several places. Justified on some of it, as you're playing a flashback to some event in your life as Revan..
- On the unknown planet, your party members will leave when you prepare to open up the temple, but Jolee and Juhani will come back and insist on accompanying you in.
- In the sequel, you need Bao-Dur to track down the Ebon Hawk on Telos. Mandalore is needed for the Iziz level before the Onderon Civil War. Kreia is required in your party during the civil war at Onderon. Also, during the assault on the Ravager, you are forced to bring Visas and Mandalore with you.
- This is continued in Star Wars: The Old Republic, where most classes has certain missions that need a certain companion. In addition, any mission classified as a Companion Mission will require that companion to accompany you.
- The Sith Inquisitor is specifically instructed to take Khem Val with him for Zash's ritual, because Zash accidentally possessing him is a major plot point through the rest of the Inquisitor storyline. There is also a Sith Inquistor mission on Rishi in the Shadows of Revan expansion that you must take Talos Drellik with you, as it involves an archaelogical find, and Talos is a professional archaeologist, and he is a key part of the conversations in that mission.
- The Republic Trooper has one mission where you have to use certain companions for certain segments of the mission, and switch out when moving on to the next one. Justified because it's a sabotage assault on a superweapon, and you need your demolitions expert to plant the bombs, your tech guy to shut down enemy systems, etc.
- The Jedi Knight takes Kira along on the mission where you learn she's actually a Child of the Emperor. The Jedi Knight must also take T7 along as his companion when he goes to Dromund Kaas for his showdown and to kill the Sith Emperor, where it's Justified that due to his strong mind control powers, which only the Knight has been able to resist, only a droid, also immune to force-based mind control, could accompany him.
- In Chrono Trigger, every character (except Magus) is forced on you for a dungeon when he or she first joins. Frog and Ayla get two such dungeons and Robo is a mandatory party member when you're exploring the factory ruins. Crono is forced on you for most of the game, but eventually, he becomes optional.
- Also, there are optional dungeons later in the game that require certain characters to be in your party, namely Robo and Marle. Frog, Robo, and Lucca are each required to be in your party to finish certain optional quests, but they're not required for the dungeons/fights that are part of those quests. Finally, Magus gets some special dialogue in two others but is not required for them.
- Chrono Cross has this with Serge (and later, Lynx, after Serge's body is swapped with Lynx's). He must be in the party for the entire game, and there's no way to remove him. Playing on a New Game+, though, will earn you an item that allows you to switch Serge out for someone else in battle.
- A handful of battles in The Legend of Dragoon require certain party members to fight with you at certain points. Lavitz must be in your party during the second visit to Hellena Prison to save King Albert and Haschel is required for the fight with Gherich and every party member gets a special personal fight in the Very Definitely Final Dungeon whether you leveled them up or not.
- Played straight for most of the game yet also subverted at one point in Sailor Moon: Another Story. There are times in the game where you play as one set specific character or a set group of characters, and this holds for the first 3/5ths of the game. In the fourth "chapter" you're allowed to choose groups of Senshi, though Sailor Moon is usually required (in a few cases, Chibi Moon is). At the beginning of the fifth chapter, the Senshi split up, one group going to rescue Sailor Moon's little brother and the other to go visit the Crystal Palace. In the cut scene before choosing teams, it looks like Mars, Venus, Jupiter and Mercury are going with Sailor Moon, while the other five (the "Outers" and Chibi Moon) are the other group. However, aside from Chibi Moon and Sailor Moon, you actually can mix this up and choose whoever you want to be in which group. There is different dialogue in the cut scenes depending on who's in which group.
- In Shadow Hearts Covenant and From The New World, you don't need Anastasia or Johnny in every battle... but if you don't, you can't get the enemy's photos, because they're the ones with the cameras.
- The Required Party Members in Persona vary depending on which path you take. In the SEBEC Quest, your party will ultimately consist of the MC, Maki, Mark and Nanjo, with one slot left for you to choose, and in the Snow Queen Quest, your party consists of the MC, Yukino and Ayase, with two slots to choose.
- Nei in Phantasy Star II insists on coming with Rolf everywhere he goes until she's murdered by her "sister" Neifirst. In Phantasy Star IV, the party right up until the final dungeon is determined by the plot at any given point.
- Devil Survivor occasionally has missions where you're required to dispatch a specific party member.
- Enchanted Arms requires the player to always have the main character, Atsuma, at the head of the active party. Jarring, in that the game provides you with a large pool of optional "battle golems" to fill out the rest of your party. Not to mention that, in areas with enemies that either resist fire or possess strong water attacks, Atsuma can be a liability.
- Neverwinter Nights 2 had an interesting take on this that alleviated the more annoying aspects of the trope. It forced you to take Shandra along for an entire chapter.... but raised the party member limit by one to accommodate her, allowing you to take whatever team you were comfortable with in the previous chapters, plus her. When she died, the extra spot became open.
- Some battles in Fossil Fighters require the player to use specific vivosaurs in their team.
- Every single character in Alter Aila Genesis will be a Required Party Member at some point in the game. Many times in fact, as the plot continually divides and regroups the party. Thankfully near the end you can choose who you want in your party and who all you want to toss out out their butts.
- Guild Wars features a few quests and missions which require a particular hero in the party. It also has the inverse; a quest in which you can't bring a particular hero, lest the correct NPCs fail to spawn.
- Mass Effect 2 has Jacob, Miranda, Jack, and Garrus invariably join you before the second plot mission but the one with most impact on the plot is Prof. Mordin, whose genius provides most of the success-relevant tech on the Normandy. However, you cannot expect to survive the Suicide Mission without losses with just the required party members.
- You also have to bring each party member along on his/her loyalty mission, for what should be pretty obvious reasons. Because of this, loyalty missions tend to be tailored to the associated party member's special skills.
- Mass Effect 3: Liara for the Thessia and (DLC) Eden Prime missions, Tali (if she survived 2) for the first and last missions of the geth-quarian arc, and EDI for the assault on Cerberus headquarters.
- The early missions in the third game force you to take along an exact party: Anderson on Earth, Ashley/Kaidan and James on Mars (until you meet Liara, then Ashley/Kaidan and Liara), and James/Liara on Menae (unless Garrus survived; then he'll replace Liara). In all cases, the game goes out of its way to justify what the other characters are doing, and you don't have anyone else in your party to bring.
- And throughout the entire game you have to pick up James, EDI, and Liara and they cannot be killed outside of a Bad Ending or otherwise removed from the ship, nor is there any point in the previous games where they can die. Garrus is similar, but he can die in the finale of the second game, in which case he won't appear in the third.
- Pokémon does this to some extent. It requires you to bring along a mon with certain special attacks if you want to get through certain dungeons. Particularly, you need Rock Climb to face Red in HeartGold/SoulSilver.
- Also sometimes a factor with event legendary Pokemon. You have to bring the three Legendary Golems, Regice, Regirock and Registeel, to Snowpoint Temple to wake up Regigigas in Pokemon Diamond And Pearl and Platinum. (And unless you trade or use Pal Park to bring those mons over from Pokemon Ruby And Sapphire, you need the special movie Regigigas to awaken the three golems in DPP, in order to wake up the other Regigigas.) Other examples include needing Celebi in your party to get Zorua and needing the three Legendary Beasts for Zoroark in Pokémon Black and White . In HeartGold/SoulSilver, bringing the Pikachu-colored (Shiny) Pichu to Ilex Forest shrine is necessary to get Spiky-Eared Pichu.
- Other times, the event mons are needed to trigger in-game events. Black and White have specific events for Keldeo, Meloetta and Genesect, and Pokémon Yellow has a surfing game that needs the Surfing Pikachu to activate. The Gold and Silver remakes have the Arceus Event, requiring an Arceus as your lead Pokemon to activate it, and the Giovanni battle, which requires specifically a DS-generation event Celebi to activate it.
- A staple in Dragon Age:
- In Dragon Age: Origins, you must bring Oghren on the Anvil of the Void quest, Alistair to the Landsmeet, Zevran to the final fight against the Crows, provided he chooses to stay with you, etc. The various personal quests also require the companion they are associated with for obvious reasons except for Morrigan, who inverts it: her assignment requires you to avoid bringing her along when you face Flemeth. On larger scale, you can kill or drive away pretty much any party member in the game except Alistair and Morrigan until the engdame (when you can drive even them away by recruiting Loghain and refusing the Dark Ritual, respectively). Ultimately subverted with Alistair during the Final Battle, however: even though as a fellow Gray Warden, he is supposed to face the Archdemon with you, you can just as well leave him behind.
- In Dragon Age II, most of the Companions' Personal Quests will require you to include them in the party. The one exception is Aveline's Act II Personal Quest which involves her attempts to woo Guardsman Donnic (keyword: attempts). There are also various points in the main plot in which companions may be required, such as Varric on the Deep Roads expedition.
- Dragon Age: Inquisition is a touch better about this, as your starting party (Cassandra, Varric, and Solas) are the only members whom you cannot drive away through disapproval, nor can you kill any of your party in battle. However, it uses the Mass Effect loyalty mission scheme as described above, with the exception of Cole's personal mission, which requires him, Solas, and Varric in the same party. (Thankfully no combat is involved, so you're not penalized if your Inquisitor happens to not be a tank.)
- There are two points during Might and Magic VIII where a specific character is required (above the undroppable hero). First the troll Overdune Snapfinger has to be recruited as a witness to the Lake of Fire's creation (this is not so bad, since it is still relatively early in the game, and the structure of the quest means no major combat is necessary during the parts where Overdune is required). Secondly, the cleric Dyson Leland is necessary for either variant of the quest where you align with the Clerics or the Necromancers (this is annoying, since Leland is liable to be more underlevelled than Overdune, and you have to take extreme measures to avoid having to have him in the party during the combat segments).
- This happens extremely often in Tales of Xillia 2, forcing an entire party formation on you for every story chapter but the last one, and requiring one or two specific members for the character episodes. Naturally, they end up making you have to fight That One Boss using a formation that doesn't have any of the party's primary healers...
- All the party members introduced in Eternal Eden is integral to the plot in some way, and to make sure their role gets properly established throughout the game, one member always dies/leaves the party before a new one is introduced.
- This is not really the case in Fallout: New Vegas (with the exception of companion quests, which obviously requires the associated companion but are not needed to complete the game unless you want 100% Completion). It does, however, show up in the Dead Money and Honest Hearts add-ons, which both have main quest stretches that require a specific companion.
- Fire Emblem has several chapters in most of it's games where a character is forced into the party and absolutely must be used for that chapter.
- Unfortunately, you usually have to keep them alive too, ie., you can't just let them get beaten and leave the field; if they get beaten, they're dead.
- In Final Fantasy Tactics, an NPC will occasionally take up one of your precious party member slots, most annoyingly in the Riovanes rooftop battle where Malak is dead and can't be revived until the post-battle cutscene and a suicidally angry Rafa, who will charge headfirst into death unless your party is fast enough to intercept.
- There are various points in Cross Edge where you'll be forced into using one or two other characters during a battle. York (Main character) and Raze get this treatment the most.
- Super Robot Wars games will automatically deploy certain units from time to time for plot reasons. In addition, recruiting optional characters or secret mechs often require specific characters to set flags.
- XCOM: Enemy Unknowns final mission requires you to have your brand new super soldier, the psyonic volunteer, on the team, if the volunteer dies, its game over. Interestingly, this soldier could be anyone up to the point that they are chosen, after this, they are The Hero.
