If Tomura Shigaraki, a character from the anime and manga series My Hero Academia, had a Domain Expansion ability similar to those in the series Jujutsu Kaisen, it could potentially be called "Decay Domination." This name reflects his Quirk, "Decay," which allows him to disintegrate anything he touches. In a Domain Expansion, he could create a vast domain where everything within it would slowly crumble and decay, amplifying the destructive power of his Quirk. The name "Decay Domination" encompasses the concept of Shigaraki's ability to dominate and control the decay of his surroundings.
