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).
This video game provides examples of:
- Bat Family Crossover
- Composite Character: Most of the cast, save for the Shredder, Utrominator, and Fugitoid, are based upon their appearances from the 2007 movie, but with the voice actors of the 4Kids cartoon.
- Karai in particular, with having the 2007 movie appearance, but the 2003 cartoon's villainous role and familial relationship to the Shredder.
- 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
- Spotlight-Stealing Crossover: The game was made as a bit of a anniversary title, but mostly features characters and concepts from the 2003 cartoon and 2007 movie.
- That said, with the exception of the Utrominator, the cast is primarily main characters who originated in the 1984 Mirage Studios comics. None of the 2007 movie-exclusive characters appear, nor are any 2003 Ensemble Darkhorses like Hun or Agent Bishop present.
- Wutai: Castle.
