A devout pacifist, Mighty just wants to help out where he can. Unfortunately, most of the time that leads to fighting. He joined the Freedom Fighters because of the opportunity to travel -- Mighty wants to see the world someday -- given that it's not been ravaged or destroyed by Eggman's actions. He can't stand for the endangering of innocents, and, as such, will gladly put his pacifism to the side to fight for what's right.
