''Teenage Mutant Ninja Turtles: Smash Up'' is a 2009 PlatformFighter for the {{Wii}} and PlayStation2, based on the long running ''Franchise/TeenageMutantNinjaTurtles'' franchise, developed by Creator/GameArts (who were also one of the companies behind ''VideoGame/SuperSmashBros Brawl''), with help from ex-Team Ninja employees. Unlike most TMNT games, this one is a general representation of the franchise, with very little explicit nods to any particular continuity beyond the art style (taken from the CGI film) and voice cast (which is that of the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 series]]).

!!This video game provides examples of:
* BatFamilyCrossover
* CompositeCharacter: In a way, ''everybody'' is, having the looks of the 2007 film (sans Shredder, Fugitoid, and the Utrominator), voices from the 2003 show, while having some traits of the 80s characters.
* {{Expy}}: While he's officially taken from the 4Kids series, the devs often refer to the Utrominator as the game's "Krang character".
** He could also be an expy of Ch'rell from the 2003 show.
* DownInTheDumps: [[VideoGame/RabbidsGoHome Junkyard]]
* DownTheDrain: Sewer
* FollowTheLeader: The devs are absolutely shameless about hoping to strike cloning gold ("[[SuperSmashBros Smash-Up]]"?) The franchise's done this before under {{Konami}} with ''TeenageMutantNinjaTurtlesTournamentFighters'', which capitalized on ''VideoGame/StreetFighterII''[='=]s sucess.
* GameBreakingBug: If you try to change the gameplay mode between rounds in multiplayer, the game can get screwed up and either have you play the wrong mode or some freakish amalgamation of modes. It's possible to begin playing a timed match (which is won by the last person standing or the person with the most lives when time is up) and the winner of the timed match is the player with the most kills rather than the last person standing. In essence, this bug causes ''the wrong person'' to win a match.
* GuestFighter: The VideoGame/RavingRabbids, which was the source of much outcry by fans. There's also the Junkyard level. While the turtles frequently find themselves in junkyards across their own franchise, this particular one is taken from ''VideoGame/RabbidsGoHome'', complete with the Rabbids' tower. So if you've watched, say, [[http://www.youtube.com/watch?v=T4Vjjo3IDWk this video]], you'd almost mistake it as a ''Rabbids Go Home'' fighting game.
* GuideDangIt: One of the game's characters (Ninja Rabbid) and one of the game's levels (Underground) are ''physically impossible to unlock'' unless you go online and look up two separate cheat codes. Keep in mind that the game is pretty shy on characters and stages to begin with by modern standards.
* JungleJapes: Jungle
* LimitedSpecialCollectorsUltimateEdition: The game comes with a comic detailing the whole story, which adds an explanation for at least one stage in the game, as well as a prologue detailing the Fugitoid talking about his misfortune.
* MascotFighter
* PlatformFighter
* RoleReprisal: Interestingly, this game brought back the 4Kids cast from the 2003 series. This and ''WesternAnimation/TurtlesForever'' marks the final vocal appearance of the 4Kids cast.
* {{Wutai}}: Castle
