Right, in no particular order.....The hooded clawSkeletorMum-raThe JokerMutley (not really a vilian but brilliant anyway!)
I seem to recall that Mum-ra was jacked when he was on the juice. It never lasted long though; he should have just stayed on the sauce forever! Think about it... old decrepit mummy takes something and transforms into vigorous hulking monster with bulging muscles. Tell me some bodybuilding fan didn't write that stuff.
Yeah Mum-ra was cool as fuck, Im not saying his obvious roid usage affected me but when I was about 7 I swapped my "Chips " police bike for a syringe!!
