The only reason there are teen supes like Spider-man early career is because almost all pulp and comic heroes were white guys of indeterminate man age until like 1957. Teenagers were side kicks, although sometimes the side kicks were more focused on for the storytelling.

Anyway, just read different books. Go read Maximum Carnage, Pete’s about 30 in that book. Or go read Some thing like Once and Future if you want real age diversity.
