Hey, sweet to see this going somewhere!

So, I was playing around in Photoshop anyway and made this (totally not my drawing btw, I just traced and colored someone else's excellent work):[hider=Bug Arm™][img=http://f.cl.ly/items/1k0k3d0m0Y0v0A3V0g3j/Bug%20Arm%E2%84%A2.jpg][/hider]

It occured to me that it might be fun to play a mutant like the dude above, but I'm obviously unsure of which mutations you'd be cool with, if any. I'd like to hear what you have in mind.
