FFFFFFFFFWUT.

This is what happens when I'm hyped up on Cheetoes and Vault. A cracked-up Star Trek/Batman crossover. xD Spock is the Joker (for the lulz), Kirk is Harley Quinn (for too many reasons to name xD), Bones is Scarecrow (think about it), Uhura is Catwoman (does that really need explaining?), Sulu is Poison Ivy (lololol, it works), Chekov is Robin (because he is adorable), aaaand since the roles seem to be in reverse, Nero can be Batman (COMMON he already has the voice!). xD
Ffff, can't think of anything for Scotty, though. D:

_{And yes, I see the flaw in Chekov being Robin while Nero's Batman. Look at me care.}
