I think Acts of Vengeance was the one time I recall Graviton being used to a closer approximation of his actual potential.
Yeah, when Loki took over Electro as well. Electro is like having Ronnie Raymond as Firestorm. You need the Professor to even remotely be able to allow the character to achieve what he can. Firestorm in theory could be a top 5 power class but he's not.
Electro is kinda the same thing. I still hate the black rubber suit and blue skin though.
I get the electric zap mask is silly. It was a product of it's day but something a bit more of an homage could've been done.
