Frankly, 90% of the time the origin is just a meaningless distraction. Superheroes with gimmicky superpowers are pure premise. Do we really need to know WHY Beast Boy is green and can change into animals? He's green and can change into animals. Why? Because he's Beast Boy. I'm not saying that having a history and a past is bad, but like, we care about the Uncle Ben and responsibility and blah blah hero's burden, academic poor geeky, etc etc part of Spider Man's origin story. But do we really care that he was bitten by a radioactive spider? It's just a tag line that was used to sell shit back in the Atomic age of scientific marvel.
