Crash gives me the most trouble out of all the Jocks for drawing. I got two fellas among the Jocks who are short and stout. Distinguishing between them without making Crash look like a frickin alien instead of a mutated dead human is pretty hard.
Exploding pus bubble skin for maximum damage. If he ever goes Uber, it'll spew acid instead of just deadly bacteria.
(I did originally draw him with an acid-eeking grated stomach, but I decided there were too many iterations of that already in the group and didn't match his personality anyway)
