But Peter's goop makes one more resistant to getting Spider-Powers if MJ is any hint, unlike Banner's where his blood gives powers, so it's not comparable too.
Look, I know you want MJ to have powers, and if writers really wanted to, they could could retcon and say that the cure only supressed the Spider-Powers, and that they'll return after a while, and without the risk of her becoming a giant spider to boot, and if that happens, or something similar, then we have have a Spider-MJ, but otherwise, there's nothing about MJ getting Spider-Powers that made her different, Peter's goop delaying 'em aside.
Plus, if MJ were to get 'em, I'm sure Marvel wouldn't use Spider-Island, because MJ getting/keeping those powers from what is possibly from Peter's jizz is... Questionable, to say the least, would be hilarious though, but not something that should officially be happening.
Holy **** that's some Joker-like smile.
Seriously, MJ looks kinda scary, it's kinda like Peter in ASM#122, after Gwen died, Peter looked so pissed he was scarier without the mask, this MJ smiling like the Joker is in a similar situation
