Everyone's got their favorite superhero, but none are as consistently badass as James Howlett. Sorry, Logan. Sorry again, Wolverine. With incredibly quick healing powers, an indestructible metal alloy grafted to his skeleton, and three claws that emerge from his fists, Wolverine quickly made an impact in the comic book world with his first appearance in 1974. He has since been the front runner of the X-Men, discovered his mysterious past with the Weapon X project, and joined the Avengers not too long ago. But really, it's those claws that make him liquid cool.
