Guest Fighter

http://static.tvtropes.org/pmwiki/pub/images/75b9102eabb6b76ef04cc4f367034017.png

A Guest Fighter is a character that doesn't belong in the setting who just shows up in a Video Game, especially a Fighting Game, much like a Special Guest on a TV show. It seems like if a fighting game hasn't had a full-blown Crossover, it has at least had a Guest Fighter or two.

Guest Fighters are quite the Base Breakers; depending on who you ask, they are either awesome and hilarious because they're fishes out of water bringing all their superpowers and continuity nods to the conflict or detracting from the premise of the established fictional universe and/or a cheap cash grab because they're... fishes out of water. That being said, the Guest Fighters least likely to inflict base breaking are the fishes whose styles and settings are more in water, such as Link in Soulcalibur II or Freddy Krueger in Mortal Kombat 9, or guests in Massive Multiplayer Crossover games in which case there is no such thing as a fish out of water. And even then, it's still not a sure bet.

The trope name comes from the Super Smash Bros. Brawl website, in which the name is used to refer to Solid Snake and Sonic the Hedgehog, the two characters outside Nintendo's ownership.

In nearly all cases, those characters are Unexpected Characters, so Guest Fighter can be considered a subtrope of that.


Examples:

    open/close all folders 

     Fighting Games 

  • Super Smash Bros.:
  • Cartoon Network: Punch Time Explosion had Captain Planet who was an Unexpected Character to everyone. In the story mode, he made a Big Damn Heroes moment where he saved the other 14 heroes from The Narrator's Evil Remote Control. And he can use all the elements for attacks.
  • The earliest known fighting game with a guest fighter would have to be the first Fighter's History game by Data East, which its final boss is Karnov from the arcade game of the same name, who also appeared in later titles in the series (and also appeared as an enemy in Bad Dudes and Trio the Punch). However, he wasn't playable until the arcade game was ported to the SNES with a cheat code to play as him.
    • In Fighter's History Dynamite (known in Europe as Karnov's Revenge), another guest fighter appears as a Bonus Boss, which was the Ox from Data East's 1984 Karate Champ.
    • In the Japan-exclusive Super Famicom title in the series, Fighter's History: Mizoguchi Kiki Ippatsu!!, the final boss this time is another guest fighter, Chelnov, from the run 'n' gun arcade game Atomic Runner.
    • Makoto Mizoguchi from this series made two appearances as a guest fighter: the first was in Suiko Enbu: Fuu'un Saiki (with Liu Yungmie), while the second was in KOF: Maximum Impact Regulation A.
  • Although both the Fatal Fury and Art of Fighting franchises take place in the same universe, Ryo Sakazaki from the Art of Fighting series appearing in Fatal Fury Special (an update of Fatal Fury 2) as the secret final boss counts.
    • Geese Howard from Fatal Fury appears as a secret final boss in Art of Fighting 2, though with a different appearance, due to Art of Fighting being placed chronogically before Fatal Fury, thus making the Geese in AOF younger.
    • Truly a remarkable example because from one simple guest appearance, the entire The King of Fighters franchise was given birth (which is like "Guest Fighter: The Game", at least in its original design, as not only did characters from Fatal Fury and Art of Fighting appear on the roster but so too did non-fighting game characters from games such as Psycho Soldier and Ikari Warriors). KoF in itself has had a few guest fighters (particularly in XI where characters from fighting games like Savage Reign and Buriki One got to join the cast). And while it features characters from multiple universes, KOF '94 can be considered the earliest cross-over fighting game.
    • Leaving aside the games that explicitly fold into it, The King of Fighters: Maximum Impact 2 has fun with this trope. Hanzo Hattori and Fio both show up... and are quite confused (Hanzo wonders what happened to ninjitsu when he meets Mai, and Fio mistakes Ralf and Clark for Marco and Tarma, respectively). Its update, Regulation A, also has Mizoguchi, though he's notably the first and only non-SNK character to join the KOF cast.
    • Clark and Ralf make appearances in Metal Slug 6 and 7, as well as one or two of their signature moves. Leona is an add-on character in Metal Slug XX, the PSP re-release of Metal Slug 7. Additionally, Metal Slug Defense has all 3 of them, plus Kyo, Iori, Benimaru, Goro Daimon, Mature, and Vice, as purchasable units.
    • The King of Fighters 2000 has Assist Characters known as strikers to help you out. Some og them are from other SNK games, such as Rocky from Robo Army, Duke Edwards from Burning Fight, and Neo & Geo from Quiz Dai Sousa-sen. (The first two are from Beat 'Em Ups, but Neo & Geo are from, oddly enough, a quiz game.)
    • The King of Fighters 14 will have Mui Mui from the Pachislot game series Dragon Gal as a playable character. A supposed screenshot of the roster was leaked and shows Mui Mui and other fighters before they were revealed. She's a member of the "Another World" team, which includes Nakoruru and Love Heart, the protagonist of another pachislot game, Sky Love.
  • Gon in the console port of Tekken 3. Almost two decades later, Akuma from Street Fighter crashes Tekken 7: Fated Retribution on a mission to hunt down Heihachi Mishima.
  • The Soul series is downright notorious for this:
    • Link, Heihachi and Spawn in Soulcalibur II. The catch is that each of these three are exclusive to a single console (GameCube, PlayStation 2 and Xbox, respectively). The HD remake for the Xbox Live Arcade and PSN brings only Heihachi and Spawn back (not Link for obvious reasons), but now both are available across both platforms.
    • Lloyd Irving in Soulcalibur Legends.
    • Darth Vader, Yoda and "The Apprentice" in Soulcalibur IV; the latter is effectively an Early-Bird Cameo. The catch for the first two is each of them are playable from the start exclusively on one console (Vader on PlayStation 3 and Yoda on Xbox 360) and are paid Downloadable Content on the other, making the pair from a technical point of view the first fighting game DLC characters, predating Makoto Nanaya by almost two years.
    • Kratos in Soulcalibur: Broken Destiny. The eponymous God of War, not the Tales of Symphonia character despite Lloyd's earlier presence.
    • Ezio Auditore da Firenze in Soulcalibur V.
    • In Soul Calibur III, It is possible to create KOS-MOS in the Character Creation by using all of the "Type X" parts.
    • Likewise, Soul Calibur V has a fighting style based on Devil Jin. Tekken's producer, Katsuhito Harada, appears as a bonus character in Quick Battle mode using this style. In the game, he's known under his Twitter handle Harada_TEKKEN, and wears an outfit resembling Heihachi's gi.
    • While not Guest Fighters in the same sense as the others, there are also a number of characters who were created for the series by well known artists. In this sense, they count as well.
      • Necrid was designed by Spawn creator Todd McFarlane for Soulcalibur II, the game which McFarlane also made a toy line for (the making of which was conditional on Necrid's inclusion). He was available on all three console versions.
      • Angol Fear was created by Keroro Gunsou creator Mine Yoshizaki. She is a cousin to Angol Mois from that series and made a one-off appearance in chapter 148 of the manga after her debut, making her a genuine retroactive guest.
      • Ashlotte Maedel was created by Oh! Great.
      • Kamikirimusi was created by Mai Hime character designer Hirokazu Hisayuki.
      • Scheherazade was created by RahXephon creator Yutaka Izubuchi.
      • Shura was created by Gantz creator Hiroya Oku.
    • All these guest fighters have background stories and plots that sufficiently explain why they are in the series. However, they are never actually referenced again or even hinted about having existed at any point, and have zero impact within the story. The 5 created characters for IV, including Angol Fear, are an exception as they are actually mentioned as part of the story, with Ashlotte having the strongest connection due to her part in the story for V's new Astaroth.
      • On another note, Ubisoft's Word of God on Ezio's presence is that it is easily explained through the Animus, the decidedly time-spanning but not universe-spanning Framing Device of the Assassin's Creed universe. Though at one point the Soulcalibur community manager noted the fuzziness of Ezio's timeline during the events of Assassin's Creed: Brotherhood (the incarnation used in V), suggested that it was actually time/dimensional travel instead of Soul Calibur V itself being a video game inside the Animus. The latter seems to be backed up by Ezio's official profile, which has him retrieving an item from the Templars that seems to briefly transport him to 1607, this leaving erratic readings in the Animus.
    • And Yoshimitsu could be considered one, atleast in spirit, given a similar character exists since the first Soulcalibur. While vaguely hinted at first, it was confirmed for V that this Yoshimitsu is the founder of the group the Tekken Yoshimitsu forms part of, and the first in a long line of successors carrying the same name.
  • Nicole-458, a female Spartan from Halo who appears in Dead or Alive 4. It's worth noting that she has never appeared in any actual Halo media, since she was created specifically for DOA4.
  • The Japanese version of Marvel Super Heroes vs. Street Fighter had Norimaro, an original character created by Japanese comedian Noritake Kinashi. He carried around a little satchel full of props as he fought. His super move was to fling every prop in the bag in a giant shotgun-blast of random objects. When he won, he'd pull out a little camera, hold it at arm's length, turn it around, and snap a picture of himself. He was removed from the US version, although data for him still exists in the game.
    • Preceding that, Akuma appeared in X-Men: Children of the Atom. After that there was Anita from Darkstalkers in Marvel Super Heroes. Similar to The King of Fighters example, the use of Capcom-owned characters in their Marvel Comics-licensed fighting games predicated the start of the Marvel vs. Capcom series.
    • Akuma also appeared in the console version of Cyberbots as a mecha under the name "Zero Akuma". This characters was very likely inspired by Cyber Akuma, the final boss in Marvel Super Heroes vs. Street Fighter.
    • Sakura also shows up in the first Rival Schools game.
    • The now-discontinued PC mouse game Street Fighter Online: Mouse Generation had several crossover characters from other licenses, namely Wuxia novels by Jin Yong, Cyborg 009, Kiminori Wakasugi from Detroit Metal City and the title character from Space Sheriff Gavan.
  • MegaMan.EXE and Zero are unlockable fighters in Onimusha Blade Warriors.
  • K-1 fighter-turned-comedian Bobby Ologun appears as the final boss in the PlayStation 2 port of Power Instinct Matrimelee. He uses much Gratuitous English and has a Beam Spam super called "Bobby Beam".
  • In Dragon Ball Z Budokai Tenkaichi 3, Arale Norimaki from Dr. Slump is an unlockable character. Justified in that Arale did appear in episodes 55, 56, and 57 of the first Dragon Ball anime series, so when they said they would put everyone in Budokai Tenkaichi 3, they really meant everyone.
    • And in an example of Guest Stage, Penguin Village is an unlockable stage.
  • The Japanese version of Dragon Ball Z: Budokai 2 had an alternate costume for Frieza, as his son Kuriza from Akira Toriyama's self-parody manga Neko Majin Z. Neko Majin himself appears as a guest assistant character in the Japanese version of Dragon Ball Z: Supersonic Warriors 2 for the Nintendo DS.
  • Naruto Shippuden: Ultimate Ninja Storm 2 allows you to use Lars Alexandersson from Tekken 6. Namco Bandai has the rights to both series and Naruto author Masashi Kishimoto designed Lars's alternate outfit, so he reappears here with said outfit and redesigned to fit with the art style of the game.
  • Similar to the WWE Smackdown: Just Bring It! example, Fred Durst was also featured as an unlockable character in the ill-advised fighting game adaptation of Fight Club.
  • Similarly, rocker Henry Rollins has a sizably role in Def Jam: Fight for NY, featuring the eponymous rap label's performers. Actors Omar Epps and Danny Trejo also make appearances and are playable characters.
  • While not a playable character, Donkey Kong is a not-so-secret challenger in the Wii Punch-Out!! title. He would only appear during the last phase of Career Mode: Mac's Last Stand. Win or lose, once you met him, you could fight him any time in Exhibition Mode. But because all opponents at this point are random, you ran the risk of him being Lost Forever if you lost the Last Stand before fighting him.
    • For the GameCube port of EA's Fight Night Round 2, you can play as Little Mac in his SNES appearance.
  • Ready 2 Rumble Boxing: Round 2 has hidden boxers including basketball star Shaquille O'Neal, Bill & Hillary Clinton, and Michael Jackson.
    • Could possibly count Rumbleman, who's basically boxing announcer Michael Buffer hopped up on Venom.
  • Three Raving Rabbids with different movesets in Teenage Mutant Ninja Turtles: Smash Up (One normal, one in Splinter Cell gear, and one in TMNT getup). This caused an eruption of "ruined" cries among the TMNT fanbase.
  • Ryougi Shiki of Kara no Kyoukai in Melty Blood.
  • Fate/Unlimited Codes had a guest appearance by the Lancer from the 4th Grail War, who is from the same fictional universe but from a different time period than the one covered by the game.
  • Earthworm Jim has appeared as a guest fighter in Clay Fighter 63⅓ and the PC edition of Battle Arena Toshinden. In the former, he has his own moveset and even his own story and stage, but in the latter, he is just a bonus skin for Rungo Iron.
  • Mortal Kombat
    • Kratos again in the PlayStation 3 version of Mortal Kombat 9. Given that Mortal Kombat is set in a multiverse and and has a penchant for gore-tastic fighting, Kratos fits right in.
    • In Mortal Kombat X, fellow horror icon Jason Voorhees appears as a DLC character. His announcement date was also fitting — he was announced on a Friday the 13th. A second guest character in the form of Predator also comes over as DLC.
      • Two more guest fighters join Mortal Kombat X through its "Kombat Pack 2": Leatherface from The Texas Chainsaw Massacre and a Xenomorphnote  from Alien.
      • Additionally, Jax has a DLC "Carl Weathers" costume based on his appearence as Dillon, the Jerkass teammate of Dutch from Predator.
  • The Japanese Sega Saturn version of Fighting Vipers had PEPSIMAN! as a secret playable character. Only in the original Japanese Sega Saturn release, sadly..
    • Interestingly, the Arcade version has some unused Guest Fighters that were Dummied Out in the final release, that were likely added as a joke and not meant to be in the full game: Sonic, Tails and Takashi Iizuka (director of Sonic Team). However, they are still playable thanks to emulation hacking. Source links. Sonic being there was the result of a bored programmer, and Yuji Naka saw it and loved the idea, thus Sonic the Fighters was born.
    • Sonic the Fighters originally had Honey the Cat, an original character based on the same character from Fighting Vipers. She was Dummied Out in the original Arcade version of the game and the Sonic Gems Collection re-release, but she's now avaliable for play in the PlayStation 3 and Xbox 360 digital re-release.
  • Fighters Megamix, aside from being Virtua Fighter 2 vs. Fighting Vipers, also features many weird and out-of-place characters from other Sega AM 2 works, who were added clearly Just for Fun. Including Bean the Dynamite, Bark the Polar Bear, Akira and Sarah (from Virtua Fighter Kids), Siba (a scrapped character from the first Virtua Fighter) Janet, Rent-A-Hero, Hornet (yep, you can fight as a race car), Deku, Mr. Meat and Palm Tree (A 3D version of the palm tree from Sega AM2's logo!). Needless to say, as crazy as this game and it's roster was, it was great because it was 100% grade A Guilty Pleasure.
  • Cloud, Tifa, Yuffie, Vincent, Zack, and Sephiroth (the latter two making their first playable appearances) in Ehrgeiz, plus the final boss's first form looks suspiciously similar to Red XIII. Incidentally, this was the only reason most fans bought the game.
  • Street Fighter X Tekken on PlayStation 3 and PlayStation Vita had FIVE Guest Fighters.
    • Firstly, there's Cole MacGrath of inFAMOUS. He's then joined on the same platforms by two cats (Toro and Kuro) that are Sony's mascots in Japan. Plus Bad Box Art Mega Man, and Pac-Man riding a Mokujin robot. The former three are avaliable from the start of the game, while the later two were released as free Downloadable Content. Needless to say, the five of them are major Base Breakers.
    • To an extent, Poison counts as this. She was from the Final Fight video game series, and while she did make an appearance with Hugo in Street Fighter III, she wasn't playable. Street Fighter X Tekken is the first time she's playable in a Street Fighter game.
  • PlayStation All-Stars Battle Royale has several characters that are from third-party games: Big Daddy (2K Games), Heihachi Mishima (Namco), Dante (Capcom), and Raiden (Konami) are in the launch roster, and Isaac Clarke (EA) is in as Downloadable Content.
  • Vattroller X for the Game Boy Advance features Zoro, Kogenta and Beet as secret characters who are unlocked by passwords available in Japanese cards of the Vattroller X manga.
  • Spider-Man was a guest fighter in the Activision title X-Men: Mutant Academy II.
  • Arm Wrestling (a Punch-Out!! spinoff) involves this; the third round is against Mask X. But, during the round, pull off the mask and looky here, it's Bald Bull from Punch-Out!! The text also says, "Wow!!! Bald Bull!!!"
  • Terry Bogard and Benimaru Nikaido in Xuan Dou Zhi Wang. The fact that XD clearly takes inspiration from The King of Fighters has not been lost on fans, which is probably the reason SNK struck a deal with Tencent to put the two in the game in the first place.
  • Scorpion is part of the cast of Injustice: Gods Among Us as DLC. A little unusual, sure, but doubles as a Mythology Gag towards Mortal Kombat vs. DC Universe.
  • Baoh's Ikuro Hashizawa in JoJo's Bizarre Adventure: All Star Battle, but only technically as Baoh is another manga by JoJo's Bizarre Adventure creator Hirohiko Araki.
  • Akira Yuki again in Sega and Dengeki Bunko's 2D Massively Multiplayer Crossover fighting game Dengeki Bunko Fighting Climax, acting as a boss character. Pai Chan serves as his Assist Character.
    • The console versions get two more with Selvaria Bles and her assist character, Alicia Melchiott.
    • On top of that, none of the stages in the game are from any visual novels. Instead, they are from Sega games, such as Sonic the Hedgehog, Phantasy Star Online 2, NiGHTS Into Dreams, and 7th Dragoon.
  • Divekick has Johnny Gat of the Saints Row series as one of the new characters in the Addition Edition. Shaundi also appears as an assist character in one of Gat's moves. The fencer from Nidhogg also arrived in a later update.
  • Aggressors Of Dark Kombat has Kotaro Fuuma from World Heroes making a guest appearance.
  • Alongside its original cast of characters, indie game Project G featured Zero from Mega Man X two years before Marvel Vs. Capcom 3 did.
  • Killer Instinct (2013) brings in Rash from the Battletoads series. He will be a member of the Season 3 cast in 2016 but was released to players for a limited time in an early form in August of 2015. In early 2016, it was announced that the Arbiter from Halo and General RAAM from Gears of War would be joining the cast as well.
  • Newgrounds Rumble's second release included Fancy Pants from Fancy Pants Adventures. Unlike the other characters in the roster, he's not a Newgrounds original.
  • The Grim Adventures of Billy & Mandy video game included General Skarr as a secret character. While he did appear as a minor character in the series down the line, he was originally from Billy and Mandy's sister show, Evil Con Carne.
  • The online game American Dad vs Family Guy has Ryu appear as the final boss.
  • Cartoon Network's other fighting game, Titanic Kungfubot Offensive has some playable characters from shows that did not originate from CN, which includes JohnnyTest, Duncan, and Chef Hatchet.
  • Whenever a big crossover fighting game is coming out, you know that someone's gonna make a fake leak. Some of them are outright jokes. Take this "leak" of John Cena in Marvel vs. Capcom 3 for example.
  • For April Fools Day, Skullgirls released a prank saying that Zone-Archive's Zone-Tan would be a playable DLC character. Zone's... *ahem* "fans" would know that her bio and playstyle have references to Zone-Tan's creation and short appearances, such as having a demon slaying mother, welding a size-changing key as a weapon, and, of course, having her pet tentacle monster Lemmy help her out in the fight.
  • In the PSP rerelease of Street Fighter Alpha 3, Capcom Fighting Evolution's Ingrid was a hidden playable character.
  • The Super Puzzle Fighter and Super Gem Fighter featured Super-Deformed versions of Street Fighter and Darkstalkers characters. However, both games had one character that wasn't from either series. Puzzle Fighter had Devilotte from the Giant Mech Fighting Game Cyberbots appear as a secret character, while Gem fighter had Tessa from Red Earth.
  • Mischief Makers' Marina Liteyears made a playable appearence in the Japan Only Rakugaki Showtime. She can even use her trademark shaking abilities after picking up a Smiley Ball
  • Nitroplus Blasterz Heroines Infinite Duel features Saber in all of its versions while Homura and Heart Aino are available as Downloadable Content in the console versions.

    Action 

    Action-Adventure 
  • In The Cat Lady, you actually get to meet Joe and Ivy from Downfall. Similar to the Street Fighter-Final Fight example, both Downfall and The Cat Lady share the same universe.
  • In the alien invasion game Under the Skin, one of the areas your alien prankster attacks is Raccoon City and your antagonists in that area include Jill Valentine (the Resident Evil 3 version of her).
  • The Wonderful 101 has Bayonetta, Jeanne, and Rodin as hidden playable characters.
  • Rumble Roses's Reiko wasnote  a multiplayer skin on Metal Gear Solid 3: Subsistence.

     Beat 'Em Up 

    First/Third Person Shooter 

    Dating Sim 
  • While they're not technically fighters due to the game being a Dating Sim, Namco High includes three characters from Homestuck (Jane Crocker, Terezi Pyrope, and Davesprite) due to the author being a major part of the development. All three are referred to as "weird exchange students" in the character info.

    Hack and Slash 

    Minigame Game 

    MMORPG 

    Platformer 

    Puzzle Game 

    Racing Game 

    Rhythm Game 

    Role Playing Game 

    Sandbox 

    Shoot 'Em Up 
  • Armed Police Batrider has guest appearances from what the Attract Mode calls "Raizing All-Stars"—five Mahou Daisakusen charactes and two Battle Garegga characters (each with two ships to their name).
  • Gunbird 2 featured Aine and Morrigan as hidden characters (the latter being only in the Sega Dreamcast version, which was published by Capcom).
  • In Blue Wish Resurrection Plus, Eden's Edge/Eve is available for play. In the creator, X.X's next game, Eden's Aegis, Eve and Ridmie from Eden's Edge and Green Wind respectively are available for play if certain conditions are met.
  • Paul Phoenix and Heihachi Mishima of Tekken in Xevious 3D/G, of all things.

    Sports Games 
  • New International Track & Field is a sports game for the Nintendo DS. The characters are big-headed and Super-Deformed, and overall it has a kiddie aesthetic. It was also published by Konami, who thought it a good idea to put a bunch of their characters in it. These vary from the fitting, such as the mascot of their Pro Baseball series with similar styling, to the somewhat out there but not terrible weird, like Simon Belmont and Sparkster, to completely family-unfriendly characters like Pyramid Head and Evil Rose.
  • The Gamecube version of NBA Street 3 has Mario, Luigi and Peach as playable characters to make up for the console's lack of online play. Plus, all versions of the game have the Beastie Boys as a secret team.
    • SSX On Tour also had the trio (Cube only, obviously.)
    • SSX 3 also had Stretch, one of the characters from NBA Street, as a secret character, as well as all the characters from the previous games.
      • And in that same game, the secret character Churchill debuted as a Quake III: Arena custom skin. Yes, it's true!
      • Stretch's inclusion in SSX 3 mirrors SSX riders Zoe and Moby's status as unlockable characters in the original NBA Street, along with Tracey from Sled Storm. Also in that game? R&B group 3LW.
      • Also Zoe and Psymon were playable in Sled Storm.
  • Also notorious for this: the Tony Hawk's series had some weird guest skaters. Some are from Activision's game catalog (the Doom guy, Guitar Hero characters), others licensed by the company (Spider-Man, Wolverine, Shrek), and musicians as well (Billie Joe Armstrong, Travis Barker, MCA). The rest are there just for fun, fictional (Darth Maul and Jango Fett; Eddie; Bigfoot) or not (Benjamin Franklin?!).
  • Similarly, Mario Hoops 3-on-3 featured a White Mage, Black Mage, Ninja, Moogle, and Cactuar from Final Fantasy, due to Square Enix being the developer. Mario Sports Mix featured the same guest characters, plus Slime from Dragon Quest, and added Behemoth as a boss.
  • NBA Jam featured anyone and everyone from the designers to President Bill Clinton as hidden characters.
    • Of particular note is that the NBA asked Midway to remove Raiden, Scorpion, Sub-Zero and Reptile of Mortal Kombat fame from later revisions of NBA Jam Tournament Edition because they were not at ease with MK being Rated M for Money. You read that right.
    • Then again, a notable guest in Electronic Arts' installment is Isaac Clarke from Dead Space. Apparently, either NBA has issues with characters from fighting games and yet has no problem featuring a character who gets graphically chopped up by necromorphs or the times have changed on the subject of video game violence since the Mortal Kombat controversy.
    • They seemed to change their minds on this early, as Raiden and Shinnok are playable in NFL Blitz. Scorpion and Sub-Zero also made appearnces in ‘’MLB Sluggers’’, but that was made by a different company.
  • Virtua Striker 3 and 2002 has a Sonic team consisting of the hedgehog and his friends. Yuji Naka is also an announcer and coach of Sonic’s team.
  • NHL 12 features an All-Legend Team, made up of NHL greats like Wayne Gretzky, Mario Lemieux, Gordie Howe, Ray Bourque, among others. You can even put them on your favourite teams, presenting interesting situations all around.
  • Jak, Daxter, Ratchet, Clank, Kratos, Sackboy, Kat, and Toro have all made appearances in some of the later Hot Shots Golf games.
  • The Surf's Up video game had Elliot from Open Season as a secret character.
  • Of the 20 newcomers Mario & Sonic at the Rio 2016 Olympic Games introduced, Sticks the Badger is one not to originate from a video game. She came from the Sonic Boom cartoon. She's even from a different continuity from the other Sonic characters.

    Stealth-Based Game 
  • Among the original students that wander the school in Yandere Simulator, there's Pippi, the mascot of the rhythm game osu!. She even plays osu! in the game! However, just because she's from another series doesn't mean she's immune to the wrath of the school's local Yandere...

     Strategy Game 
  • One mission in Warcraft III is infamous for having a Hydralisk you can add to your forces. The character models for Terran Marines and Zerglings are also available.
  • Interestingly, Plague Inc, a game about killing humanity with diseases, got its first official Guest Fighter in the form of the Simian Flu from Dawn of the Planet of the Apes, which was a result of a partnership with 20th Century Fox.

    Survival Horror 

     Wrestling Games 
  • Limp Bizkit frontman Fred Durst is a playable character in WWF Smackdown: Just Bring It! Rumor has it, this was one of the conditions for allowing the developers to use the song "Rollin'", which was Undertaker's entrance theme at the time, in the game.
    • The more recent WWE games feature hidden "legends"; in other words, popular wrestlers from WWE's past.
    • WWE SmackDown vs. Raw 2011 also features Rob Van Dam, who hadn't been in WWE for a couple of years prior to the game beginning development and, indeed, signed with TNA shortly after its release. He's listed as a "Free Agent", not as a Legend (the only other characters so designated are the Red and Green demonstration models, Paul Bearer, and the Undertaker's druid). Apparently, the dev team were just really big RVD fans and wanted to use him in the game very badly.
    • WWE '12 featured the returns of Brock Lesnar and Eddie Guerrero.
    • WWE '13 featured Mike Tyson.
    • WWE 2K15 features Sting, the first wrestler to be featured in the game despite never actually having wrestled for WWE.
    • WWE 2K16 features not one, but two versions of the Terminator.

     Vehicular Combat 
  • Twisted Metal
    • Rob Zombie shows up as a driver in Twisted Metal 4.
    • A Warhawk from the the game of the same name is the Final Boss in Twisted Metal: Black. Serves also as a Call Back, as the original Warhawk was developed by the same team that did the first two Twisted Metal games and Black.
  • While not "characters" per se, Rocket League features a few "guest cars: first is the PS4-exclusive Sweet Tooth from Twisted Metal, and DLC later added the DeLorean from Back to the Future. And with the announcement of an Xbox One version, a variation of the Warthog from Halo and the Armadillo from Gears of War join the roster.
  • Beyond Games' Motor Mayhem included three characters from Ultra Vortek, a mediocre Mortal Kombat clone: Volcana, Grok, and Buzzsaw

    Non Video-Game Examples 
  • In a non-Video Game example, one episode of Celebrity Deathmatch had Beavis And Butthead fight against each other. While both shows were on MTV, Celebrity Deathmatch focused on parodies of real celebrities fighting to the death, not animated cartoon characters, making their match rather unexpected.
  • Hayden Moss is known for competing in Big Brother, but he also competed in Survivor: Blood vs Water. He got in because his then girlfriend was a former Survivor contestant, and former Survivors competing against loved ones was the main gimmick of the season.
    • Fellow contestant Gervase Peterson references this in one of his voting confessionals.
    This isn't Big Brother, it's Survivor. We do things different here.
    • In a related example, Big Brother 17 contestants Jackie Ibarra and Jeff Weldon first appeared in The Amazing Race.
    • Big Brother 15 contestant Caleb Reynolds appears as a contestant on Survivor's 32nd season.
  • Miyamoto Usagi is known for his frequent appearances in Teenage Mutant Ninja Turtles media. His appearance in the 1987 cartoon (In which he was actually called "Usagi Yojimbo") was a set up for his own cartoon that was never made due to Creative Differences. He's more accurately portrayed in the 2003 cartoon. His world is the setting for a few episodes, characters like Tomoe and Gen appear, and Usagi is as close as a brother to Leonardo.
  • The Simpsons episode "A Star is Burns" had Jay from The Critic guest star. It's the only episode to not have Matt Groening's name in the opening and closing credits, as he felt that it was a 22-minute advertisement for The Critic.
  • Queen's Gate Sprial Chaos, an ecchi redesign of the Queen's Blade series, has had a girl from pretty much every major fighting game featured as a playable character. This includes Lili, Mai, Mina, Cham Cham, Iroha, Dizzy, Noel, Kasumi, Ivy, Taki, and Phyrra. The only girl not from a fighting game is Wonder Momo.
