This man's a real one.
Brennan Wiliams, AKA GreatBlackOtaku, currently known as Mace in the WWE, has always been a pretty well respected figure on 4chan. Posted on /sp/ for a while, has mentioned reading /cgl/ cringe threads, browses /a/, and prior to actually being a pro wrestler he was obsessed with monday night raw and posted on /woo/ (420chan's /pw/ precursor).
One time he came on with a trip on /vp/ after challenging people to competitive pokemon on twitter, and whuped everybody's ass.
Currently he's an indie vtuber alongside his pro wrestling career. Has a... unique model.
Still, really cool guy. He's a father, too. If there's anybody who could push a Hololive/WWE collab, it'd be him.
