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 time.

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.
