I don't want to see heroes losing their powers. It's really dissatisfying for me to watch. The first time I saw when heroes losing their powers was Power Rangers Ninja Storm TWICE! Heck I don't like it when Death took out the Alucard Weapons from the videogame called Castlevania Symphony of the Night(unless you cheat your way to keep them).
Can't they're be a conflict without losing or in exact term crippled, nerfed, drained their powers AFTER ALL THE HARD WORK, TRAINING, AND PERSERVERANCE(not to mention the timeskip, aging up to teen, giving them upgraded designs) the heroes been through?!
I can accept happily ever afters taken away, or falling from grace situations like the Ghostbusters did, and/or losing control of vast powers in an apocalyptic way then people hate you now, but not nerfing, draining, a hero's powers.
Why can't have a similar situation like(a ticking time bomb on a watch/powers or abandoning the hero work by removing a watch/weapon then put it back later on/regain them) Kinda like when Ben Tennyson did or what Hector from Castlevania Curse of Darkness did respectively.
Or holding back your vast powers on your own free will without the nerfing. Coz if you don't hold back there will be conscequences like your loved ones will suffer, doomsday weapon activates, timer accelerates via a threat?
Or said weapon/power will not work unless a special key, ritual, upgrade is needed like Jonathan Morris carrying the Belmont Vampire Killer from Castlevania Portrait of Ruin.
