I very much like OP characters. The problem is, if you truly want to make a story with an OP character, you can't write it in the same way a traditional action story might take. If the MC is truly OP then your MC never truly fights; he/she only performs one-sided beat downs. If there's an actual fight, the MC isn't actively participating in it.
Because of that, the tension in the story has to come from elsewhere. For example, if the MC is trying to hide his abilities, which is often a staple of the trope, then the difficulty arises with the MC trying to manoeuvre everyone else away from the conflict so he can act discreetly.
So if you want to make a story with an OP MC, you need to be able to highlight what's stopping the MC from acting.
Now, a common problem I notice with OPMC stories is that they try and put someone else on the same footing as the MC to try and make actual tension in the fights. This has two problems. Firstly, if all antagonists are able to compete with the MC, then the MC no longer feels OP, breaking the initial premise of the story. Secondly, it greatly reduces what you can do with the other supporting characters. After all, they need to be much weaker than the MC to keep the premise up, but then they become nothing more than damsels in distress.
After
@CharlesEBrown Brought up Superman, I started thinking a bit more about it. I wouldn't classify superman as an OP character, because I feel like all his opponents are meant of a similar strength to him. And if superman does have allies (I'm thinking stuff like justice league) then he's of a similar power level to his allies. Hmm. He might make for a good case study on OP MCs, even if we don't consider him one.
