So I have watched the Captain Harlock anime, and it's hard not to notice the scar across his face or the father-daughter relationship he has with his friend's daughter. And you are probably thinking "well yeah, because Tezuka made Black Jack before Leiji Matsumoto made Captain Harlock, since the former debuted in 1973 and the latter in 1978."
Yes, but according to Wikipedia, Harlock's first appearance was in 1953, in Matsumoto's work "adventures of a honeybee", link here: . Not that the reference to supposed debut date nor the connection to Black Jack are cited.
So, thoughts? Which had the scar first?
