Anime where the MC is the only one with a superpower?

I’m looking for anime where the MC possesses a unique ability which makes him overpowered and/or alone, like Boku dake ga Inai Machi and Steins;Gates. It can be a psychological anime or a comedy, as long as it’s a real, serious ability, but it’s important that the MC’s the only one with a power. (not Code Geass for example)
