Generally speaking, most long term comics fans know that Bob Kane is probably the biggest piece of shit in the history of the industry. Went out of his way to make sure that Bill Finger and Jerry Robinson could not be given credit for creating Batman. And then he’d show up to conventions in a limo, dressed in three piece suits and walk around acting like he invented the whole idea of comics. The fact that Batman Vs. Superman officially credited Bill Finger as the co-creator of Batman in the credits was a HUGE deal. And it only happened because the legality of the deal Bob Kane wrote up behind Bill Finger’s back expired. Something about it only being effective as a licensing statute for a certain number of years. Bob Kane took it that far. He made sure Bill Finger would never be given credit while Bob was alive. Piece of shit. He’s like the example of how not act as a creator.
This is who Bob Kane created:
That’s his original idea for Batman.
Everything else was Bill Finger.
