Developers Foresight / Fighting Games

• From Blaz Blue Chrono Phantasma onwards, the Mirror Match theme — Blood Pain II — will also play for Jin vs. Hakumen matches. By this point in the series, this is more of a Late-Arrival Spoiler.
• Dragon Ball FighterZ
  • Typically, when Android 18 uses her Accel Dance super, Android 17 joins her. If she is on the same team as Krillin, however, her husband will join her instead.
  • Beerus's level-3 super has two different animations. Typically, it consists of Beerus flicking his opponent on the forehead, like when he first fought with Goku on King Kai's planet. If the attack does enough damage to KO Goku Black or Fused Zamasu, however, the animation is changed to Beerus erasing Black and/or Zamasu from existence as he does Present Zamasu in Dragon Ball Super.
  • If Gotenks is on the same team as Piccolo when using his Charging Buu-Buu Volleyball attack, Piccolo will join in.
  • If Adult Gohan is not on the same team as Gotenks, his Ultimate Kamehameha super will change into the Brothers Kamehameha, which he fires with Goten by his side^note Goten can't join in if Gotenks is on the same team, since he's fused. Additionally, if Super Saiyan Goku^note And only Super Saiyan Goku, no other version of Goku will work is on Gohan's team while Gotenks isn't, Goku will join in and turn it into the Family Kamehameha.
  • Depending on the combination of team compositions and stage selection, extra cutscenes may play before a battle begins or after a battle ends that pays tribute to key events in the series. For example, if Goku and Frieza are the lead characters on their respective teams when starting a fight on Planet Namek, a cutscene will open of Frieza murdering Krillin, triggering Goku's transformation into a Super Saiyan. If the stage is transformed into its destroyed version as a result of a Destructive Finish, and Goku wins against Frieza in the end, another cutscene will play of Goku flying away, Frieza launching one final attack on Goku, and Goku countering and killing Frieza.
• Dragon Ball Xenoverse 2: DUAL Ultimates are powerful combo attacks with which your hero uses one of a given character's strongest moves in tandem with that character (for example, the Kamehameha with Goku). Android 16's is Hell's Flash — and 16 has to detach his hands to use it. However, when your hero uses it, they mimic the initial pose... but fire the earth-shattering blast from their open palms instead. The same happens if they use Eis Shenron's Ice Cannon, which is ordinarily fired from his left arm shifted into an Arm Cannon.
• In Fist of the North Star: Twin Blue Stars of Judgment, Kenshiro's "Hokuto Zankai Ken" super imposes a time limit on his victim, in which they lose the round via classic Hokuto pressure point hitting when said timer runs out. However, when done on Souther, nothing will happen to him at all when the timer runs out and he even laughs about it, reflecting his dextrocardia immunity to Hokuto Shinken.
• Garou: Mark of the Wolves: If you selected an alternate color for your character, then they will be depicted with said alternate color in all pixelated cutscenes. Hand-drawn CGs do revert to the default color, however.
• The Grim Adventures of Billy & Mandy:
  • Every playable character has a different quote for when the final boss fight begins.
  • Should the player choose to play through story mode while wearing an alternate costume, Mandy will be wearing one of her own alternate costumes during the part where the player has to control her and make her beat up Billy during the end credits.
• The console versions of Guilty Gear XX Accent Core up to Plus R include a bonus "GG Generations" option which changes the game's mechanics slightly to resemble previous games. "GG" mode changes how Instant Kills work so that they can be repeatedly used and escaped from via onscreen button prompts. If the victim misses the inputs they eat an immediate unfailing Instant Kill. Yet Order-Sol's Instant Kill "Dragon Install Sekkai" is a long and complicated button combination, and the actual IK portion only triggers if the victim's health is low enough, so how did the dev team work around this? When Order-Sol's in "GG" mode, performing a successful IK here triggers his EX form's IK, "All Guns Blazing."
  • May's Instant Kill in Xrd (where she blasts her opponent into the sky with one of the Mayship's cannons) gives May unique dialogue when she uses it on Johnny, the owner of the Mayship. Also, Dizzy's Instant Kill (where she diverts an incredibly powerful Kamehame Hadoken before Necro can vaporize her opponent with it, and her opponent surrenders after seeing the ensuing mushroom cloud in the background) gets absolutely no reaction from Bedman (who's in a coma throughout all his fights) but gets one from his bed mecha, and Elphelt using her Instant Kill (where she fires a special bullet at her opponent that makes them fall in love with her) has dialogue from a Mirror Match Elphelt lampshading how she's being seduced by herself.
  • Xrd in general has a surprising amount of this. Each character has a different reaction to Dizzy's IK, for example. Certain character combinations will trigger special dialogue under certain conditions as well - Sin's IK has special lines that only ever trigger when facing Dizzy, Sol, or Ky. Faust's dialogue is noticeably more hostile whenever facing Zato, someone he has a very bad grudge against. Elphelt has a special winquote that only triggers when defeating Sin.
  • In Strive, winning a fight as Goldlewis Dickenson will have him pull out his stopwatch and remark on how long it took to beat his opponent, with his lines corresponding to how much time has actually run down on the fight timer. However, setting the time limit to endless will instead amusingly have him say "Zero seconds! Wait, that's not right. Is my watch broken?"
• In Marvel vs. Capcom 3, the Kattelox Island stage normally has Tron Bonne in the background next to Tiesel Bonne, cheering on the fighting. If Tron Bonne is one of the fighters, though, she will disappear from the background and Tiesel will cheer her on instead. One step further: If two Trons fight each other, Tiesel will appear confused and stare at the two of them trying to work out what's going on. If Tron is defeated, Tiesel will hunch over and look depressed for the rest of the match... unless another Tron enters the match (either by the enemy player using her as well, or using the Multi Man card in Heroes and Heralds), which will cause him to be confused for a while before starting to cheer again.
• Skullgirls: One detail that was actually voted for by the fans concerns Beowulf and Black Dahlia: Beowulf has a "Hype" mechanic where he uses certain follow-ups and taunts to get the fight's audience pumped up to make his moves stronger, which is indicated by an invisible audience cheering him on. However, if he is fighting in Black Dahlia's night club against her, the audience will boo at him instead; they're not going to cheer for their employer's opponent when she can hear them.
• Slap City:
  • Each character has their own win quotes after a Vs. match depending on who you beat. This also applies to many of the alt skins (as they are different characters using the same moveset). There is also unique dialogue for winning a team match and a 4v4 match. They even have lines for the scenario in which a person in a vanilla character skin set beats someone using an alt skin set of the same character.
  • Princess Remedy and Frallan canonically used to date in their own series and can marry in the first game. As a nod to that, If Princess Remedy and Frallan are in the same match, and one grabs the other, they can press the taunt button to do a special "throw" (it's them kissing). Also, if specifically both of them are on the same team and win a match, there's not only unique dialogue, but a unique victory animation, neither of which plays if Remedy teams up with Frallan's alt character, Nuna.
• In Street Fighter IV, the Small Airfield stage has Balrog ("Boxer") appear in the door of one of the planes. If Balrog is one of the fighters, Vega ("Claw") will appear instead. If both Balrog and Vega are fighting, M. Bison ("Dictator") will appear instead. This is also also a reference to how these three characters had their names swapped around between the Japanese and English version^note Respectively, Boxer, Claw, and Dictator are known as Mike Bison, Balrog, and Vega in Japanese, hence the use of nicknames.
• Super Smash Bros.:
  • Super Smash Bros. Melee will properly display the name of Giga Bowser on the jumbotron of the Pokémon Stadium stage should he somehow appear there. Additionally, otherwise unused announcer voiceclips will be spoken if Giga Bowser wins a standard match (provided that the game doesn't crash) or if the game is hacked so that Giga Bowser can be selected from the standard character select screen. There's even a separate clip for Giga Koopa, as Giga Bowser is named in Japanese (though the game calls for the wrong clip depending on the set language; if it's set to English it will call for Giga Koopa and vice versa).
  • Super Smash Bros. for Nintendo 3DS and Wii U has the Spirit Train from The Legend of Zelda: Spirit Tracks as a stage, with Link operating it. But if either Link or Toon Link (or Young Link in Ultimate) is selected to fight, then Alfonzo will be driving the train. Similarly, the Dream Land 64 stage still has the "King Dedede sometimes floats by in the background" element that it had in both the original Super Smash Bros. and Melee, but unlike those two games, Dedede is playable now, and if he's selected to fight, that background element simply won't appear.
  • Super Smash Bros. Ultimate:
    • Assist Trophies and Poké Ball Pokémon will not spawn from their respective items if they already have a presence on the stage. Alucard will not spawn on stages with reflections or mirrors due to him being a half-vampire.
    • Palutena's Guidance for Cloud mentions how his Finishing Touch attack deals high knockback despite only doing 1% damage. However, if the current match is a Stamina match (where knockback matters much less), Pit will remark that he doesn't need to worry about that.
  • Palutena's Guidance in general will have differences depending on if its opponent is using a male or female variation, or if the alternate color is someone different like Alph or the Koopalings. Similarly, Snake can't make a CODEC call about Ike in his Radiant Dawn visage; it has to be the Path of Radiance version which featured in Brawl.
  • Despite Master Hand only being playable through hacking the game or in the penultimate battle in World of Light, the Pokémon Stadiums will still feature its name in the screen. Similarly, it will also appear in the Boxing Ring screen (its title being "The Puppeteer").
• In the obscure 90's fighting game War Gods, Pagan's "Medusa's Head" fatality involves her pulling out the gorgon's head, which turns the opponent into stone then blasts them to pieces. But if her opponent is Tak, who's already a Living Statue, the "turning into stone" part won't work on him and he'll taunt the head instead. Medusa still blasts him to pieces.
