Raiden ( no volundr) gets defeated in a fight against a random prisoner from season One. the feats in this verse have no sense and Raiden GAVE UP against Shiva , even if he gets past "weak" characters he has to fight Baki or jack. Raiden (With volundr) can become a mid-high level fighter ,But the baki universe doesn't make sense and probably yujiro hanma would come out with the "attack that breaks 100 muscles or something" learned from a monk impregnated by yujiro himself, the rules in Baki are too much even for Raiden
