''Teenage Mutant Ninja Turtles: Smash Up'' is a 2009 PlatformFighter for the UsefulNotes/{{Wii}} and UsefulNotes/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: Most of the cast, save for the Shredder, Utrominator, and Fugitoid, are based upon their appearances from the [[{{Film/TMNT}} 2007 movie]], but with the voice actors of the [[WesternAnimation/TeenageMutantNinjaTurtles2003 4Kids cartoon]].
* DownInTheDumps: [[VideoGame/RabbidsGoHome Junkyard]].
* DownTheDrain: Sewer.
* {{Expy}}: While he's officially taken from the 4Kids series, the devs often refer to the Utrominator as the game's "Krang character".
* 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.
* JokeCharacter: The controversial Rabbids are this for obvious reasons. None of them can take a hit well and they don't have anything to really compensate for that weakness.
* JungleJapes: The stage aptly named "Jungle" which is like JungleJapes but without the japes.
* 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.
* SpotlightStealingCrossover: The game was made as a bit of a [[MilestoneCelebration anniversary]] title, but mostly features characters and concepts from the 2003 cartoon and 2007 movie.
* {{Wutai}}: Castle.
