Sargon Troopa II was a primordial Koopa who dynastically ruled the throne of Koopalonia throughout most of his life in the 17th century B. C. His life and reign came to an end when Koopel, the Deikoopa of balance and karma, cursed him for his violent doings, but his ghost remains within his kingdom to this day. Sargon Troopa II is notably comparable to modern-day Koopas by his inability to walk on his hind legs.
