Super Duper Sumos for Nintendo Game Boy Advance
In Super Duper Sumos, three 18-year-old Sumos travel to the modern world
with ancient powers to defend the innocent and battle the evil Ms.
Mister and her cohorts. You can choose to play as Booma, Defender of
Peace; Kimo, Defender of Honor; and Mamoo, Defender of Truth. The Sumos
are supersized heroes in a normal-sized world and use their special
powers--"Gluteus Maximus," "Honorable Thunderball," and the "Sumo
Squeeze"--to double in size and destructiveness in order to fight evil.
