reminding myself that superhero fiction exists outside marvel/dc
Consider the following:
JJBA
Zorro
Super Sentai (and arguably kaiju in general)
Mega Man
Inspector Gadget
Hellboy
Sentinels of the Multiverse
Sailor Moon
@KommaChameleon
Miraculous Ladybug
Ben 10
Kamen Rider
Guilty Gear is another I should remember; it is a universe principally concerned with tons of unlikely powers and ridiculous costumes but with enough divergence from our world to feel like those kinds of powers changed the status quo.
Also, closer to home, TMNT.
