Member of Team Mansion. Ranked last in jump maps. Obsessed with girls but picks fights with guys. Hated by everyone (even the viewers), but he's the only one who doesn't realize it. A total simp. Doesn't get discouraged at all even when girls give him the cold shoulder. He's ugly but acts like he's handsome and shows off. A typical loser. His skill level is so low he can barely clear the easiest jump maps.
