The next step in human evolution is your genetics; you have evolved well past human limits, becoming as close as a normal human can get to being a mutant without being one. While others rely on fancy superpowers, you have pure strength to get you by. Your strength and durability have been raised well beyond normal human limits, allowing you to crush a building with pure, unadulterated power. People with fancy magical powers never train, so one good hit could knock them over like a deck of playing cards. This is not just limited to giving you strength; you also possess enhanced durability and speed, allowing you to keep up with those who are stronger than you by a slight margin. You are fast enough to outrun fast cars and those who have been enhanced with the powers of a spider and precognition.
Despite not being supernatural, you also possess the ability to nullify supernatural powers that are targeting you, walking straight through magic that very well should kill you.
