Claus

Claus is a character in the Game Boy Advance video game Mother 3. He is the slightly older twin of the game's protagonist Lucas, and is easily more excitable than his younger brother. He only fights once in the game, and that's near the beginning. After this, his whereabouts are unknown until the very end of the game.

It should be noted that his name can be rearranged to his brothers' name Lucas.
