Spiderman has spider powers. This is because he was bitten by a radioactive spider, which gave him the abilities of a spider. These powers include enhanced strength, agility, and the ability to climb walls. Spiderman also has a "spider-sense" which alerts him to danger. Additionally, he can shoot webs from devices he created called web-shooters, allowing him to swing through the city and catch criminals. Overall, Spiderman's powers are all related to spiders, hence the name.
