I think officially, Spider-man is said to be able to 'press lift' anywhere from 10 to 25 tons.
But in a fight, Doctor Octavious claimed that he had measured Spider-man's strength level and he should not be able to break apart / defeat his tentacles. But Spider-man easily breaks them apart and replies that his new Mk. 4 Spider Armor enhances his strength allowing him to break them.
...Or at-least the fight went something like that. I don't exactly remember though since I'm working off of memory here.vidmate mobdro word counter
Anyway, how much stronger does the Mk. 4 Suit make Spider-man?
