@OverLordArgeist: Are you talking about Superior Spiderman or Spiderman in general, because the symbiote did increase his strength slightly. Not to the same ratio as Brock though obviously. He was able to man handle the Rhino for instance who was class 30 when Parker had the symbiote.
Depends on the Spider-Man. Classic Spidey didn't have any boost as the symbiote increases ability as it goes host to host. 90s - Modern Spider-Man on the other hand, had a slight increase from 10 to 15 tons I think it was + the organic webbing.
Hmmm. Did not know that. I would also like to include that the suite also add weakness to spider-man such as sonics and fire. All in all it may not be worth the boost.
BTW, I only saw the Rhino thing on the animated series where Parker almost kill Rhino due to the influence of the symbiote.
Well in the back in black story, he wore the suit and he was around 20 tons(Venom can do 25 I believe). I don't remember him having the weaknesses either. Not that it matters here, because Hisoka is not going to capitalize on it during this battle.
