->'''Kirby''': Ooh, since Link isn't here, can I give Meta Knight an intro?\\
'''Meta Knight''': A what-?\\
'''Kirby''': Meta Knight has joined the team! He can carry people to higher areas, also occasionally teaming up with Tails to do so. When Team Luigi takes control, his cape transforms into wings that allow him to fly. His battle ability is being able to don brief invincibility for a short time.\\
'''Knuckles''': I like mine better.\\
'''Princess Peach''': Do I even need to mention that I still didn't get one?
-->-- ''Super FanFic/PaperMarioX'', Chapter 47

[=RPGs=] tend to make a [[SeriousBusiness big deal]] about who is and who isn't part of the player's travelling band of heroes racing to save the world from those evil machinations of the BigBad. Expect to see some fanfare (such as a possible music riff) whenever a ChekhovsGunman sheds their "{{NPC}}" label and submits to the player's team management; typically with a message announcing how "X joined the party".

Compare ItemGet.

Common enough that only examples that are [[PlayingWithATrope played with]] should be listed.


[[folder:Adventure Game]]
* ''VideoGame/StrongBadsCoolGameForAttractivePeople: 8-Bit Is Enough'' does this, being an AffectionateParody of old videogames. ___ HAS JOINED YOUR PARTY!

[[folder:Role Playing Game]]
* ''VideoGame/ShadowHearts'' series has a RunningGag that Roger Bacon ''pretends'' to join your party (complete with 'Naming screen') but never actually does it. The naming screen shows up in the later two games, even though you ''can't'' rename characters in either of them.
* ''VideoGame/ChronoCross'''s messages are personalized for each character's accent/verbal tic/gimmick. "[[ValleyGirl Marcy, like, joined your party!]]" "[[NoIndoorVoice ZOAH JOINED YOUR PARTY.]]" "[[MaskedLuchador Greco tagged into your party!]]" "[[OurFairiesAreDifferent Razzly joined your party-hee!]]" "[[SurferDude ~Doc joined your party, dude!]]" "[[MachineMonotone Grobyc-joined-your-party.]]"
* In ''VideoGame/StarOceanTheSecondStory'', if you refuse to help Ashton out after putting him into [[MultipleHeadCase his unfortunate predicament]], then return to him immediately after the party expresses some guilt over ditching him, he'll chew them out and force himself into the party with an appropriate notice.
* Whenever a team member joins the party in ''VideoGame/SuperMarioRPG'', Mario spins around and makes a VSign, in addition to a short musical ditty. The actual text varies depending on who joined and how; for example, since Bowser refuses to admit that ''he's'' joining ''Mario's'' cause and claims he's only letting Mario join his Koopa army, the game announces "Mario and his friends have joined the Koopa Troop! (or so they're pretending) Bowser joins the group..."
** In the first ''VideoGame/PaperMario'' after you reach the top floor of Boo Mansion, Bow joins your party, as the text box notes, "''like it or not!''"
** In ''VideoGame/PaperMarioTheThousandYearDoor'', after you beat [[spoiler: Doopliss (for the second time)]] in Chapter 4, [[spoiler:Vivian]] is said by a text box to have "''really'' joined your party now!" Also, in Chapter 5, when Flavio accompanies Mario to the entrance to the Pirate's Grotto, a message appears stating that "Flavio will join you for a short time" even though he only follows Mario around and does not act as a partner. Most of the other tag-along characters join without a message of that sort.
* ''VideoGame/SkiesOfArcadia'' announces that "Drachma joined your party... again" after said character rejoins for good after dropping in and out of the party several times in a short timeframe. Much later, one crewmember brings with him a twist on the "X joined your crew as a Y" message: "[[TeamPet Pow]] joined your crew as a Jester... of sorts."
* In ''VideoGame/FinalFantasyIV'', a minor NPC joins your party at one point even though it's full. But before you regain controls he already turns out to be a monster in disguise.
* When Cait Sith joins in ''VideoGame/FinalFantasyVII'' at the Gold Saucer, it's shown as Cait literally [[PartyInMyPocket walking into Cloud's body]] while Cloud tries helplessly to stop it from happening.
* ''VideoGame/DragonQuestVIII'' has the characters do a little pirouette and bow to cutesy music when they join your party.
* In ''VideoGame/{{Persona 4}}'' if you return to a certain dungeon (that happens to be built entirely as a homage to 8 and 16 bit jRPGs) at one point and add Yosuke to your party he will comment [[LeaningOnTheFourthWall "Yosuke joined your party! ... or something like that, right?"]]
* When someone joins your party in ''VideoGame/{{Fallout 3}}'' and ''VideoGame/FalloutNewVegas'', a pop-up message appears telling you so. This was absent in the first two games of the series, when potential companions would just start following you after their recruiting conditions were met.
* In ''VideoGame/KnightsOfTheOldRepublic'', one character who will later join your party has some rather awkward lines about how if you help him and allow him to "join with you" he'll help you out.
* You get this with eggs and in game gifts in ''Franchise/{{Pokemon}}'' games. "*player* received the Egg from the day care man!"."*Player* received *Pokemon!*". Played mostly straight in Ilex Forest in the Gen II remakes during the Pichu event and the Gen V Zorua event.
* VideoGame/TheLegendOfZeldaLinksAwakening: How does Marin "join" you as a temporary companion? Link (literally) picks her up and the ItemGet jingle plays!
* You're told "(X monster) has joined you" when you successfully recruit demons in most ''Franchise/ShinMegamiTensei'' games. However, sometimes you can say the right things to a demon and have them join without negotiations. In which case you're told "(X monster) forces itself into your party!"
* ''VideoGame/{{Lunarosse}}'' does this for both party members who fight on the front lines and for new recruits for help out at your base.
* ''VideoGame/RakenzarnTales'' plays it straight for both regular party members and Support members. One humorous moment is if you recruit Deadpool in Chapter 10, in which his theme plays instead of the normal jingle and the text declares he's now brigade leader. In a rare moment of fourth wall observation, Kyuu notices this and complains.
* ''VideoGame/RakenzarnFrontierStory'' has a variant on this. If a party member joins and has a [[JobSystem Rune Class]] that is equippable, you'll see what level they're going to be at as well as what skills they gained via LeakedExperience. If you get this message and it doesn't say what level they are, it means they're a GuestStarPartyMember with a class only they can use.

[[folder:Turn-Based Strategy]]
* ''VideoGame/{{Disgaea|HourOfDarkness}}'' has at least two people who join your party without your consent, and a few more who are actually enslaved by Laharl[[note]]Hoggmeiser and Maderas[[/note]].
** ''VideoGame/{{Disgaea 2|CursedMemories}}'' plays with this for most of the main characters, to whit:
--->[Rozalin] is bound to you by the terms of the ritual.
--->Deeply swayed by Adell's manliness and cologne, [Yukimaru] joined the group.
--->Beauty Queen [Etna] is stalking Adell.
--->Under the condition of three square meals a day, [Overlord Laharl] has joined the group.
** ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'' continues to play with this for its downloadable characters:
--->[[ButtMonkey Tink]] was enrolled as a student while still unconscious.
--->Mao has received the most badass [[VideoGame/MakaiKingdom Notebook]] ever.
*** At one point early in the game you get the message "Raspberyl ended up traveling with you" however she doesn't officially join your party till later.
** And in ''VideoGame/{{Disgaea 4| A Promise Unforgotten}}'':
--->Warden Axel was forced to join your party, but he's so weak and useless that he won't fight in the battles.

!!Non-video game examples:

* In ''ComicBook/ScottPilgrim'', of course. On the first pages of the fifth volume, Scott and his friends are at Julie's new apartment's Day of the Dead party. Scott and Ramona encounter her fifth and sixth exes, the Katayanagi twins, experts on robots and technology. When they challenge Scott to a fight, a robot goes inside and just... joins the party.
** Which happens in the [[VideoGame/ScottPilgrim video game]] as well. "Robot-01 joined the party!"
* ''ComicBook/{{Noob}}'' has it from time to time due to being set in a MMORPG and the main group having a HonoraryTrueCompanion.

[[folder:Fan Works]]
* As seen in the page quote above, ''Super FanFic/PaperMarioX'' does this every time a new character joins the team. [[JustifiedTrope Makes sense]], since this is a {{crossover}} with a RPG. Usually it's [[Franchise/TheLegendOfZelda Link]] who does these, but when the gang got split up starting with chapter 42, other characters have done these introductions instead. Link was quite upset that he didn't make those intros.
-->'''Kirby''': Ooh! Ooh! Link! You have to give Malon an intro! I gave Meta Knight his!\\
'''Sonic''': I gave one to Knuckles.\\
'''Mario''': I gave Luigi's and Tails'!\\
'''Link''': Aw, you couldn't have waited for me?\\
'''Kirby''': What? We had to improvise!

[[folder:Web Comics]]
* Early in ''Webcomic/ErrantStory'', Meji met Chris, a deeply stupid young man who is a parody of jRPG protagonists. He invites her to join his party, and she responds by casting an invisibility spell and slinking away from him.
* A BigDamnHeroes moment during ''Webcomic/PennyArcade'''s "[[VideoGame/DeadRising Armadeaddon]]" arc: "[[http://penny-arcade.com/comic/2006/08/18 FRUIT FUCKER has joined the party!"]]
