Well. Beowulf is actually a pretty funnily written character..
He has been described numerous times as being alot like kamina from gurren laggenn..and then the fandom and mike z added bits of macho man to him..
In addition to that he is literally a wrestling version of the literary figure beowulf. He fought the undefeatable gigan grendal in order to win the championship belt.. Hrunting is beowulf's sword name but with him it's a chair. On another note when Beowulf left his castle to fight one last time he died in the book fighting a dragon. So possible spoilers.
His name is beowulf and he wears a wulf pelt hoodie so there is a wolf pun there. And this possibly also a referance to japanese wrestling tag team get wild who did the same thing with pelts but irl.
Mike saying he's not kanji actually gives alot away..Kanji plays like a traditional grappler character..with attacks and mix-ups used to control space and lead to command throws..with no actual wrassling moves involved..Most of his referances seem different from that play style or wholly original.
and just saying there are many many many many wrestling moves to never be seen in a 2d fighting game..and so many that deserve it.
