* FanNickname: Von Kaiser's [[OneHitKill One-Hit KO]] attack in "Title Defense" mode has been given the name The [[VideoGame/FatalFury Von Kaiser Wave]] by many Punch-Out and Fatal Fury (And consequently, [[VideoGame/TheKingOfFighters KOF]]) fans.
* HeyItsThatVoice: Bear Hugger is voiced by Richard Newman (who coincidentally lives in Bear Hugger's home province of British Columbia), who is well known for playing [[WesternAnimation/BeastWars Rhinox]], another big guy. Not only that, he voiced a certain [[WesternAnimation/StreetFighter M.Bison]] who said [[MemeticMutation "yes".]]
** Also the voice behind: "[[Manga/DragonBall THE CAPTAIN'S COMING TO GET YOU!]]"
** He also voiced [[WesternAnimation/MyLittlePonyFriendshipisMagic Cranky Doodle Donkey.]]
** Piston Honda is voiced by Kenji Takahashi, who also voiced Abel from ''VideoGame/StreetFighterIV''.
*** Spanish players may also recognize the voice of Don Flamenco being Juan Amador Pulido, a Spanish voice dubber for such roles as Tom Tucker and Cleveland of ''WesternAnimation/FamilyGuy'', Shadow the Hedgehog from ''SonicX'', Gabriel of ''Series/{{Dexter}}'' and The Captain of ''WesternAnimation/{{WALL-E}}''.
** Charles Martinet provided pretty much all the voices in the SNES ''Super Punch-Out''. He is more recognizable as the voice of Mario and Luigi (among others).
** TakashiNagasako [[RoleReprisal reprises]] his role as DonkeyKong in the Wii version. He is also well known as the Japanese voices of [[Manga/DragonBall Dodoria]] and [[SonicTheHedgehog Big the Cat]].
* In the NES version, a camera held by an audience member at the top-right corner of the screen will flash when Bald Bull's bull charge can be countered.
* Little Mac (or someone that looked like him) [[http://www.unseen64.net/2009/05/26/super-punch-out-snes-beta/ was]] going to be the player character in the SNES Super Punch-Out!! before being replaced by the blond boxer for unknown reasons. Nintendo has [[FlipFlopOfGod flip-flopped]] over whether this character is Mac with a makeover or an entirely new boxer for several years.
* NoExportForYou: Inverted. Japan didn't get a release of ''Super Punch Out'' for SNES, except for a very limited edition in March 1998.
* TalkingToHimself: Great Tiger in Title Defense mode makes several illusions of himself between rounds. They hang out on the ropes talking like they're on break.
** In a more straight example, Doc Louis and Mr. Sandman are both voiced by the same guy.
*** These two characters are also the only ones that refer to Little Mac as "Mac baby".
* In an interesting coincidence, the initial barrage of punches Mike Tyson hammers you for in the NES version lasts 91 seconds, the amount of time it took Tyson to knock out contender Michael Spinks in 1988.
* The only boxers to appear in all three console versions of the game are Bald Bull, Super Macho Man, and Mr. Sandman. Due to Arcade Super Punch-Out being a MissionPackSequel, no boxer has appeared in all games.
* WhatCouldHaveBeen: The GuestFighter for the Wii game was originally gonna be [[SuperMarioBros Princess Peach]], but was dropped because of the possible UnfortunateImplications. See [[http://kotaku.com/5320198/punch+out-devs-talk-graphics-difficulty-nixed-princess-peach-idea here.]]
** Mac in ''Super Punch Out'' is blonde and tan for unknown reasons but beta footage shows him looking far different.
** Bear Hugger was originally going to appear in ''Mike Tyson's Punch Out'', but was replaced with King Hippo.
