The Joker

Strengths
♦ Utterly Unpredictable
♦ Runs on a damaged energy core, he's constantly leaking radiation that causes other machines to malfunction when in close proximity
♦ Constantly making modifications/adjustments to his build, adding elements of his victims to his own soft & hardware...
(he does this impulsively, regardless of whether or not these souvenirs are an improvement)

Weakness:
♦ Utterly Unpredictable
♦ Monologues

♦ The Joker Gear wears an ancient piece of clothing supposedly worn by the Original Joker.

♦ It's theorized that the Joker gear is in actuallity, a failed attempt to make the original Batman Gear

This is it for the Gotham Gears!! (for now) Hope you cats enjoyed  I've got some other projects to tie up, and then we'll see about getting you a scarecrow and such...
