It's weird that this version has edited out Darkshine's obsession with the perfect defense of a beetle's impenetrable chitin body. An outer shell, muscle-like in its power, capable ot defending from any attack with absolute shiny blackness. They seem to have spared his dignity a bit this time.
damn son, so the manga isn't even gonna try to explain how the beefcake trained so hard that he not only lost all his hair but also turned black. And just like that, the only mythical "OOOH, BRACK PEOPRLE" turns out to be a scrawny Japanese dude

He might've lost his hair the same reason Saitama did, or he could've just shaved it off for some reason. Some bodybuilders do that.
As for his color... i'm guessing tanning and lots of oil.
