10 Scientific Secrets Of Spider-Man Only Geeks Will Love
3. Spidey Possesses Durability Far Beyond His Slight Frame
Spider-Man is far more durable than his 167 lbs frame might suggest. His skin and muscles are far denser than a normal human's, his bones are stronger and more resistant to breaking, and Peter is able to survive impacts and events that might severely injure or kill a regular person. These include falls of several stories or being struck by opponents with super strength.
The Wall-crawler has survived direct hits from lasers, grenades - pumpkin-shaped and otherwise - gases, explosions, and punches from foes up and down the strength scale. He has even survived multiple punches from the Hulk and a beatdown from Colossus and Magik when they were imbued with the Phoenix Force in Avengers Vs. X-Men #9. Parker actually has to be careful not to tense his stomach muscles when non-powered foes are hitting him, as a boxer broke his wrists hitting Spidey in his tensed stomach early in Spidey's career.
This is not to say that Peter is invulnerable. He’s far from it, actually. While a needle would have a hard time piercing his skin, a sword would definitely do the job. Parker's skin is tough, but he is not made of Kevlar. Significantly hard blows can definitely ring his bell and he can be injured and hurt, but there is no character more famous for bouncing back from the brink than Spider-Man.
