I think Doc Ock was one of my favorite Spidey villains growing up. Moreso than the Green Goblin I think. I just found him (and Mysterio) to be what I latched on to most while watching the old cartoon. A fun, neat looking bad guy with 4 mechanical arms!
I would imagine what I could do with those arms! Gym class would be easier, Climbing trees would be a breeze, and that bully kid at school wouldn't even be able to touch me!
