We stood toe to toe with the Chaos King Mikaboshi and won. (Mikaboshi is the strongest aspect of Oblivion, who is the most powerful abstract being in the Marvel omniverse outside of the One-Above-All, as well as the origin and source of the Marvel Omniverse in the first place, and Oblivion is above Multiversal Eternity in both power and age).
In other words, he fought against the aspect of literal Nonexistence and managed to defeat it using nothing but physical combat and strength.
