Fighter 83 (ランラン老師, Ranran Rōshi; "Lang Lang Roshi") is a fighter who lost in the Elimination Round of the 21st World Martial Arts Tournament. He is a master of the Lion-style Kempo (獅子牙流の拳法家, Shishi kiba-ryū no kenpō-ka).
Fighter 83 made it to the final elimination round which would have resulted in being in the tournament, but he was set up against Goku. He thought Goku's stance was weird because it left all of his area's open, but then was quickly defeated from Goku throwing him out of the ring.
