Leagueman is Kyuuta's Net Navi, which rightfully fits him since his father is a professional baseball player. Leagueman takes the pitcher position when playing Net Baseball Games, and is a force to reckon with when he uses his signature move to gaurantee a strike-out!

Leagueman seems more suited for playing baseball rather than actual net battling. ^_^;
