Pride.
The user is an anomalous entity of reality, a broken rule beyond all understanding of the world, a singularity. The rules of logic are merely ignored, the fabric of reality ripped and torn to pieces. The user's body and mind are warped through this ability, making their physical attributes of an unreachable magnitude, and their body completely unstoppable and uncontrollable, as they can't be manipulated by anybody.
I think that this ability relates to pride as it is the quality of having an excessively high opinion of oneself. Therefore, I decided to make the user a singularity, as they regard themselves as completely unique. They cannot be tied down by any rules because they think that they are above them, making them free. Lastly, the user has physical attributes of an unreachable magnitude because they think that nobody can compare to them, making them the strongest of all.
