Golden bat in the Champion Red manga Golden Bat: A Mysterious Story of the Taisho Era's Skull
if your curious i grabbed the manga name from mangadex
anyways i like how you can tell it's based on his 60s iteration yet designed in such a way that he legit looks terrifying i like how this iteration goes all in with the "Heroic Lich" angle (as i've personally called him a lich based on his OG backstory) as he looks like something that you legit do not want to encounter in the slightest
i also like that despite being a golden skeleton he has clearly defined musculature also add the fact that his eyes are extremely detailed despite looking empty he looks more like a villain then a protagonist (which works in his favor)
i also like how they went full in with him being basically a vampire basically giving his human the ability to grow wings and such overall pretty good design (the main human Ryuji Tsukishiro meanwhile also has a pretty good design)
