Just a quick warmup sketch~
Aniki's big in-character weakness is that he cant focus on his super-human strength if he is... distracted. So to build some tolerance to it, he altered one of his vigilante outfits into a wrestling one so he could try his best head to head with various half-naked sweaty people, definitely something that would distract him~
He didnt realize how tight some of the other opponent's outfits are however, seems like a bit of an unfair advantage over him in this case...
