Paradox Scholar in the Wasteland

This is a research record of a scholar after time travel. He is very strong, has dual powers, and is conceptual, but that is not the point. The point is he's cold. He uses the [Achilles Paradox] to reject anything that comes close. He uses the "Liar's Paradox" to negate all ongoing rules. He used [The Ship of Theseus Paradox]...... If you can stand a protagonist who never changes for anyone, you might like this record
