So the TV tropes page for Captain ersatz says golden bay is based on batman. Any comments from you, the expert on this obscure early Japanese character?
THAT’S A FALSEHOOD. BALD-FACED UNTRUTH. Golden Bat existed before Batman.There IS a character based on both GB and Batsy, though, and it’s the Korean bootleg hero known as GOLDEN BATMAN (I’m not kidding, look him up)
