It doesn't have sci-fi stuff. That's a good start.

Seriously though, if I'm gonna recommend a good place to start gathering some knowledge in abilities and shit, I'll throw them to those three series first.

Touhou is huge enough that it covers nearly all fields of superpowers, the Nasuverse is unique enough that the abilties mentioned there will give some insight for more clever applications of tried and true abilities, and Umineko demonstrates how to make incredibly OP, but well-written characters.
