From
DC Comic Database it looks like he should have a Healing Factor special power and maybe a Pain Induced Laugh Special Attack or Maniacal Laugh Special Attack.
6 seems a little high for him as he seems like he's just punching people. Sure it says superstrength, but I can't see him being like Colossus strong or Wonder Woman Strong. Perhaps an attack of 5 might be a little better.
I don't know how much of a badass he's supposed to be in the comics as I have never heard of him until this thread. So ignore me if I'm off base with my comments.
If you bump his defense to 4, then between that and his move of 7 getting him to good position (either height or getting a first attack and climbing), that might be enough to represent his agility, as well as having 5 lives. So you might be able to lose Stealth Dodge.
If you get rid of Stealth Dodge, I would think you can fit in Healing Factor power since it at least seems pretty iconic for him on the DC database. You could also give him maybe a Maniacal Laugh Special Attack of 3 with a range of all figures within 2 clear sight spaces of him.
I think the Progressive Psychosis looks kind of neat, I don't know how iconic it is, but if it is, then it looks cool.
So just my 2 cents here,
Life 5
Move 7
Range 1
Attack 5
Defense 4
Cost?
Progressive Psychosis
Maniacal Laugh Special Attack
Healing Factor
Super Strength
