Juggernaut

It's Juggernaut from the X-men comics. Juggernaut is on another rampage through the city. You can be one of the Avengers and/or X-men that's trying to stop him. Heck, you can be one of the fantastic four members if you want. The only thing is Juggernaut can't be reasoned with, as he only wants to rampage and destroy everything in sight, and he cares little about who gets hurt.
