All of this shyt depends on the writer
like any of these rules we have for characters are based on whatever writer decided those rules should exist. Either to get out of a problem or create one. The reason we think one character is stronger than the other is all based on writing and who made those decisions in editorial.
Take Superman. Him being able to fly, the daily bugle, jimmy olsen, and his weakness to kryptonite were all inventions of the radio show because they needed to create drama and characters and something for sound effects. Batman’s “no kill” rule was born out of the comics code. Robin was created purely so batman could have someone to talk to rather than having it all be inner monologue.
And that’s not to take away anyone’s fun either. Just we know too much now and have seen behind the curtain.
