Abilities: When Peter Parker was bitten by a radioactive spider, he gained the proportionate strength of a spider — making him considerably stronger, faster, more durable, and more agile than the average man. He also has enhanced senses that give him incredible battle instincts, allowing him to dodge and counter incoming attacks more effectively. Plus, you know, he can shoot webs from his hands and climb up walls.

Power scale: 7. In "Civil War," Spider-Man's first real fight, he handily defeated both Falcon and Winter Soldier. He even held his own against Captain America (although Cap was clearly holding back). Spider-Man has incredible potential as an Avenger, especially now that he has a super-suit built by Tony Stark with specialized abilities like "Instant Kill." But he's still inexperienced and he can get sloppy. In "Infinity War," he was easily smacked down by Thanos and was even restrained by Star-Lord, somehow.
