Teenage Mutant Ninja Turtles: Smash Up is a 2009 Platform Fighter for the Wii and PlayStation 2, based on the long running Teenage Mutant Ninja Turtles franchise, developed by Game Arts (who were also one of the companies behind Super Smash Bros. 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 2003 series).See also Teenage Mutant Ninja Turtles: Tournament Fighters.
This video game provides examples of:
- Bat Family Crossover
- Composite Character: 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.
- Down in the Dumps: Junkyard.
- Down the Drain: Sewer.
- Expy: While he's officially taken from the 4Kids series, the devs often refer to the Utrominator as the game's "Krang character".
- Game-Breaking Bug: 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.
- Guest Fighter: The Raving Rabbids, 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 Rabbids Go Home, complete with the Rabbids' tower. So if you've watched, say, this video, you'd almost mistake it as a Rabbids Go Home fighting game.
- Guide Dang It!: 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.
- Joke Character: 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.
- Jungle Japes: The stage aptly named "Jungle" which is like Jungle Japes but without the japes.
- Mascot Fighter
- Platform Fighter
- Role Reprisal: Interestingly, this game brought back the 4Kids cast from the 2003 series. This and Turtles Forever marks the final vocal appearance of the 4Kids cast.
- Wutai: Castle
