Gaming Things We Think Are Cool!! - Games that have 'special appearances' from other game characters.
That's what this page is about.
Rules for inclusion on this page:
#1 - Only cases where the guest character is either a playable character, or an enemy, boss or interactable opponent, count. No straight-up cameos!
#2 - They must be from separate series- Ryo Sakazaki in Fatal Fury Special counts, for instance, but Hibachi in DoDonPachi Resurrection doesn't.
However, it's OK if they're in the same story continuity but originate from different series (like Street Fighter and Final Fight).
#3 - Games that are crossover games to begin with (Fighters Megamix, Super Smash Bros, etc.) don't count.
However, certain exceptional circumstances (such as Cole in Street Fighter x Tekken) will be considered.
Rules for page presentation:
#1 - English titles first, Japanese titles second.
#2 - Presented in chronological order, except when dealing with a series (i.e. Oneechabara/Aero Fighters)
We'll run through all remaining titles in that series, then go back to year order.
#3 - We'll only be listing initial/relevant release platforms and years, for space concerns.
#4 - We've divided things into 1980-1994 (previous page), 1995-1999 (this page), 2000-2009 (next page) and 2010-Present (final page).

X-Men: Children of the Atom
(Arcade / Saturn / PS1 / PC, 1994, Capcom)
To fight against Akuma / Gouki in 1-Player Mode, use Manual Block, win every match without continuing or losing a round, land the First Attack in every round, and end every match with your Hyper X attack- it must connect, and you must get the maximum number of hits from it at least once. If successful, Akuma / Gouki will challenge you before Juggernaut. [Source]
To play as Akuma / Gouki as Player 1, on the Character Select screen, move the cursor to Spiral and wait for three seconds. Then, press Left, Left, Left, Left, Right, Up, Right, Right, Down (you should end on Silver Samurai). Wait three seconds on Silver Samurai, then press and hold Light Kick, Heavy Punch and Heavy Kick. Akuma / Gouki will be selected for you.
To play as Akuma / Gouki as Player 2, on the Character Select screen, move the cursor to Storm and wait for three seconds. Then, press Right, Down, Left, Left, Left, Left, Down, Right, Right (you should end on Spiral). Wait three seconds on Spiral, then press and hold Light Kick, Heavy Punch and Heavy Kick. Akuma / Gouki will be selected for you. [Source]
All these codes should work in the home versions too.
Marvel Super Heroes
(Arcade / Saturn / Playstation / Xbox 360 / Playstation 3, 1995, Capcom)
Japanese revisions only!
In the arcade version, have the machine set to Free Play. Hold 1P Start and the 1P Coin Switch, then quickly press Medium Punch, Light Punch, Left, Light Kick, Medium Kick [Source]
... Admittedly, I can't get this working in MAME! This is the only code I've found, though. In any case, you can use MAME cheats to play as Anita (in any region, too). If you can help us with this code, please get in touch!
In-game, Anita uses Thanos' name image, pre-fight profile pic and win image/quotes. Her attacks also summon Donavan's Dhylec sword, Akuma / Gouki, and Lei-Lei from Darkstalkers.
In the Japanese Saturn and Playstation versions, first beat the game, unlock Dr. Doom (on the Character Select screen press Up twice, holding it on the second press, then press Light Kick, Medium Kick and Heavy Kick one by one, holding each one down as you press it) and Thanos (on the Character Select screen press Down twice, holding it on the second press, then press Heavy Punch, Medium Punch and Light Punch one by one, holding each one down as you press it), then on the Character Select screen press Up, Right, Down, Lfet, Up, Right, Down, Left, then hold Up and press Light Punch, Medium Punch and Heavy Punch one by one, holding each one down as you press it. For all these codes, do not move from where you start before entering the code or it won't work! [Source]
After doing this for the first time, save your game data and Anita, alongside Dr. Doom and Thanos, will be available from the Short Cut menu.
In both versions, Anita has her own pre-battle profile picture (as seen above on the left, from the Saturn port- this art is loosely based on this piece by CRMK, used in the jacket for the drama CD Vampire Hunter Legend: Donovan, The Fated Traveller- thanks to @HokutoNoShock for finding that for us) but only the Playstation version actually puts her name below her life-bar (as seen above on the right). She still has Thanos' win-screen and quotes.
In the Xbox 360 and Playstation 3 ports as part of Marvel Vs. Capcom: Origins, Anita is a character you can unlock by using 150 Vault Points, and is then selectable by pressing Back (360)/Select (PS3) on the character select screen. She even has her own moves list and hints and tips! These ports also confirm Anita was intended to be a test character. As this port is based strictly on the arcade version, she doesn't have her own pre-battle profile picture.
Yacopu is an unplayable sub-boss in the Neo-Geo MVS arcade, Neo-Geo AES home console, Neo-Geo CD and Playstation 2 versions.
In the Saturn port, highlight Vs. Mode then press and hold L, R and Y on both controllers. While holding those six button down, press Start on Controller 1. This will unlock Bonus-kun, Rouwe, Felden and Yacopu to play as (as shown on the left, screenshot from this port). [Source]
In the Playstation port, beat the 1P Mode with every character then hold down L1, R1, L2, R2, Triangle and Up and select 1P Game to unlock all the boss characters, as listed above. [Source]
When fought as a boss, Yacopu will start the first match much like he is in Trip World, with basic kicking attacks- in the second round, he will morph into his opponent. This doesn't happen when playing as him in the Saturn and Playstation ports, it's a special move instead.
Bentley Bear is available from the start.
(Sorry for the poor screenshot- Jaguar emulation is messy!)
Space Invaders '95: The Attack of Lunar Loonies
(Arcade, 1995, Taito)
Sayo & Silver Hawk
from Kiki Kaikai (Sayo) - Arcade, 1986, Taito

Sayo is partnered with a new character, Miyo, who has never appeared before or since.

Zero Divide 1 & 2
(Playstation, 1995 / 1998, ZOOM)
Beat the game as all eight characters to unlock XTAL, then beat the game as XTAL without using a continue. On the Character Select screen, hold L1, L2, R1 and R2 together, then press Select, then Start. [Source] Zero Divide 2: The Secret Wish:
Beat the game once on any setting to unlock Eve and Nox, then beat the game as Eve to unlock NECO and MODOKI. [Source]
(Screenshots here come from Zero Divide 2: The Secret Wish, mostly because we're lazy and it took way less time to do it this way. If you really want to see NECO in the first, here's a Nico video, knock yourself out.)
Street Fighter Alpha: Warrior's Dreams
Street Fighter Zero
(Arcade, 1995, Capcom)
Guy and Sodom are available from the start.
When fighting Guy, his stage uses a remix of Slum Alleyway, the Round 1 theme from Final Fight, and so does his ending.
When fighting Sodom, his stage uses a remix that combines Trashcan Strasher and Slim Subway Smash from Final Fight, and his ending uses a remix of Tool-Grabbing, the continue screen music from Final Fight
Guy also appears as a playable character in future games in the series- Alpha 2, Alpha 3, Super Street Fighter IV, Ultra Street Fighter IV.
Sodom also appears as a playable character in future games in the series- Alpha 2, Alpha 3. Amusingly, he retains his US/EU SNES Final Fight name, Katana, in the US/EU versions of Street Fighter Alpha 2 for the SNES!
Street Fighter Alpha 2
Street Fighter Zero 2
(Arcade, 1996, Capcom)
Rolento is available from the start.
When fighting Rolento, his stage uses a remix of Something Putrid by the Bay, the Round 5 theme from Final Fight.

Street Fighter Zero 3
(Arcade / Game Boy Advance / PSP, 1998, Capcom/)
Portable (Game Boy Advance & PSP) versions only!
In the Game Boy Advance version- where the screenshots above are taken- beat Arcade Mode on Difficulty Level 2 (JP) or 4 (US/EU) 7 times with 7 different characters to unlock her or, on the title screen, press Left, Right, Down, Right, L, L, A, L, L, B, R, A and Up which unlocks all other characters, [Source]
In the Playstation Portable version, Maki is available from the start.
She is based on the version of Maki that appeared in Capcom Vs. SNK 2.
PSP version only!
Ingrid is available from the start.
We ummed and ahhed about including Ingrid here, but we figured she wasn't really a Street Fighter character- first scheduled to appear in the crossover game Capcom Fighting All-StarsL Code-Holder, then dumped nto Capcom Fighting Evolution / Jam after All-Stars was cancelled- so she's technically an orphaned guest character, having no real game to call her own.
Bonus-kun is an unplayable sub-boss in the Neo-Geo MVS arcade and Playstation 2 versions.
In the Neo-Geo AES home console and Saturn ports, having a second player enter the game will add both Bonus-kun and the final boss Fernandez (Fernandeath in Japan) to the character select screen.
When you insert a coin, hold either Left or Right before pressing Start. On the Character Select screen, press Left twice then press Start. [Source]
It's tough to see, but the text on the bottom of their skis read 'SUPER OYAJI DON & DAN' and the one facing the screen changes every time you have a bad crash and tumble over.
Rival Schools - United by Fate
Shiritsu Justice Gakuen - Legion of Heroes
(Arcade / Playstation, 1996, Capcom)
In the arcade version, either hold Start as you begin the game after the machine has been operating for four weeks and move the selection cursor up or down until it's off the grid, or enter Test Mode, go to Sound & Voice, then using Player 2's controls, press Up, Up, Down, Down, LK, HP. This unlocks Hyo and Raizo. Next, in Test Mode, go to Input, then using Player 2's controls, press Up, Up, Down, Down, then switch to the Player 1 controls and press LK, HP. Hold Start as you start the game, and Sakura will be selectable. [Source]
In the PS1 port, Sakura is available from the start.
Saturn/Playstation version only!
In the Playstation port, unlock Galts (beat the game as Chiyomaru and& Tessan), Helion (beat the game as SHADE) and Super-8 (beat the game as Devilotte) to unlock Warlock, then beat the game as Warlock without using a continue to unlock Zero-Gouki (Untested!) [Source]
In the Saturn port, either beat Arcade Mode on any difficulty from Difficulty 4 upwards without continuing, or beat Arcade Mode 99 times, to unlock Zero-Gouki. [Source]
Although technically not a guest character as such- aside from an appearance as a card in Cardfighter's Clash he hasn't appeared in any other games- he's very obviously supposed to be Akuma/Gouki and even plays like him (dude, Raging Demon's totally in this game) so... It counts, I guess?
Sengoku Blade: Sengoku Ace Episode II
(Saturn, 1996, Psikyo)
Saturn version only!
(This means Marion is not in the Playstation 2 port, as part of Psikyo Shooting Collection Vol. 2: Sengoku Ace & Sengoku Blade, either).
In the Saturn version, beat the game once on any difficulty with every character (this includes Ayin- go to the Random icon and press Up, Up, Up, Down, Down, Down, Up, Up, Up, Up, Up, Up, Up to select him). This cannot be done in two-player mode! One-player only! Once every character has a checkmark on their icon, highlight the ? on the Character Select screen and press Up to select Marion (press Up twice to select Ayin again). [Source]
Suiko Enbu - Outlaws of the Lost Dynasty / Suiko Enbu: Fuuun Saiki
(Playstation / Saturn, 1996, Data East)
Playstation / Saturn version only!
In the Playstation version- titled Suiko Enbu - Outlaws of the Lost Dynasty and only released in Japan- on the title screen for Special Mode press Up, Down, Left, Right, Down, Up, Right, Left, L2 and R2 to unlock Mizoguchi in 2-Player Mode. [Source]
In the updated Saturn version- titled Suiko Enbu: Fuuun Saiki, also only released in Japan- Mizoguchi and Yungmie are available from the start and can be played in both Arcade and 2-Player Vs. Mode (this is where the screenshots above come from).
This is unconfirmed but it would appear Mizoguchi cannot be unlocked in the US Saturn version- titled Dark Legend- as no code can be found, and trying to put the Playstation version's code doesn't work.
Super Fire Pro Wrestling X Premium
(SNES, 1996, Human)
Clear World Championship Mode and save the game, then clear the Neo Heroic Belt in Title Match with the same wrestler you cleared World Championship with. This will unlock all these characters.
Please note these screenshots come from an earlier fan translation of the game, so they are using slightly different names- the ones shown in text on this page are the correct names.
(Screenshots and information provided by Jake- thanks!)
Dead or Alive
(Arcade / Playstation / Saturn / Xbox, 1996, Team NINJA/Tecmo)
Complete the Story Mode with all 16 characters to unlcok Helena, then complete Story Mode with Helena. This will also unlock her stage, Nassau Station.
Also known as Nicole, SPARTAN-458 is not based on any particular Spartan from the Halo series, but while her appearance in Dead or Alive 4 is not considered canon, she is canon in the Halo universe!
As she could not appear in future Dead or Alice games, Rachel's fighting style (as she appears in Dead or Alive 5 Ultimate) is loosely based on the one used by SPARTAN-458. [Source]
Dead or Alive Paradise
(PSP, 2010, Team NINJA / Tecmo)
Receive the Zack's Challenge item in the hotel, then go to the Casino, challenge Rio to Blackjack, and win with 1 Blackjack. [Source]

She would also get a starring role in her own anime, Rio: Rainbow Gate![Source]

She pilots the Dino 246, the same ship from Pulstar.
While Blazing Star is technically a sequel to Pulstar anyway, it's easy to miss she's supposed to be from that game, and the game was developed by Yumekobo instead of Aicom, so... We're counting it?
