The peak of power would either be continent or planetary level with anything above it being in very specific scenarios. And a lot of the top tiers’ abilities aren’t necessarily destructive, they’re mostly complex stuff that no one in the verse can overpower head on.
Uhhh...
That tells be nothing.
Magic? SUPERSCIENCE! Weird science? 1900s Gothic monsters? Lovecraftian horrors? DC style superheroes? Marvel style? Post modern deconstruction superheroes? European ambient otome? D&D knock off isekai? Cyberpunk? Post Apocalypse zombie horror? Trapped in a VR game? VR game bleeds into the real world? Environmental disaster awakens mutant/magic?
Seriously.
Wtf is the SETTING?
I’m trying to think of up a balanced power for one of my Main characters, but I don’t wanna give him something too OP since actually relying on others is a turning point for him. For reference, he’s a guy with maxed out stats in a world where the top tiers all have broken abilities that are hard to fight against conventionally. Sorry if this is too vague, but any suggestions will help.
If you just want generic ideas, that require teamwork, Here:
Guardian: He gets stronger the more people he has to protect. The most work he takes on and the more responsibility he has, the stronger he gets. He is only weak and vulnerable when he takes time off to have a life.
Know Happiness: His power is to know how to make anyone happy. True Happiness. Who their one true love is. However, some people are broken. Sociopaths might have brain damage so they can never be happy. Some people might be happy committing murder and killing. But he knows everyone's vices and what pushes their buttons.
Universal Danger Sense: He knows when people are in danger. Everywhere. He then knows their location and how they are in danger. This turns into Minority Report really fast.
Healer: See Wrong Way to do healing magic
Support Guy: He does Buffing magic
Immune to Pain: In a world of Augmented Reality where people watch other people play arena style combat while wearing AR helmets, the combatants are taken out by direct stimulation of the pain centers. The MC has brain damage that makes him feel euphoria when the 'kill switch' kicks in, allowing him to keep playing when others would pass out. He is destined to become a World Famous Player, but it is a team sport.
