Shapeshifting has always sounded like it would be a trip. Teleportation or similar also sounds super fun, and could have actual practical applications.

I guess you didn’t set a limit on how OP it could be, so I could just go for genie wish granting. Although, I can only imagine how zero challenge on literally any activity would fuck with my mental wellbeing.

Not flying, super strength or laser vision. Too much like tools we already have.
