History
When he was an active professional Super Sumo wrestler, Raiden fought and won 700 consecutive fights, becoming the Super Sumo Yokozuna and gaining a reputation as the strongest wrestler of all.

Fall of the Hero Association Arc
Raiden was once again approached by a Hero Association scout with yet another offer to join their ranks, but the yokozuna once again refused their offer. This time Raiden revealed to the scout that he was already part of the Neo Heroes, which is the new hero organization that is set to replace the current Hero Association as the defenders of mankind.
