Roy is a very proud warrior and dreams of being the best swordsman in all of the land of Smash. His biggest rival is Marth, who holds similar dreams, and they are always butting heads. They share the same relationship as Goku does with Vegeta. If one trains, the other doesn't let up to keep up with the other or to surpass them. He can come off as selfish and arrogant, but he does respect others and he does cherish friendship.
