Re: Is he strong? Listen bud...
I do agree that Spidey has tons of untapped strength, but I'm wondering if you're not thinking about the issue where Spidey, Cap America and later the FF (Reed wears a projector hat!) beat Gladiator and a bunch of skrulls disguised as (shifting) members of the X-men? He didn't really take down Gladiator and the real x-men. That time.
I actually want to see a pure Spidey vs Gladiator fight now. Spidey would outsmart him, which would be a nice change of pace (not for Gladiator, he always gets outsmarted, but it's been a while for Spidey).
