The latest TMNT Smash Up trailer introduces Donatello and ... uh ... some other people. Man, we have been out of touch with Ninja Turtles for a long time. Who are all these people? We recognize Karai from Tournament Fighters (you may recognize her from the comics or whatever), but we totally had to look up "Nightwatcher," who turns out to be Raphael in a costume. That's really weird.

The good news is that even if you don't follow the TMNT cast of thousands, the characters look fun to play. A turtle superhero! A woman with a sword! A robot! Totally great. And if you do know the characters, hey! There they are! See the trailer after the break.
