Jiren

ジレン

Jiren the Gray is a member of the Pride Troopers, a superhero team from Universe 11 that takes part in the Tournament of Power. Toppo, the leader of the Troopers, describes him as the strongest man in Universe 11. Whis goes so far as to state that Jiren is a mortal whom even a God of Destruction cannot defeat.
When Jiren was a child, his home village was attacked by a villain, resulting in the deaths of his parents. A man who later became his teacher rescued Jiren. As Jiren grew stronger, he acquired new companions. Eventually, the villain returned. Jiren and his companions believed they could win, but they were ultimately defeated, along with Jiren's teacher. Jiren attempted to rise again, but was abandoned by the fellow surviving students he had always trusted. Jiren realized that the weak could do nothing but obey the strong, which is the reason for Jiren's obsession with power.
