The Star Devourer, that is his current name.

This is the name given to him by those white-coated mad scientists in the Electronic Wizard Laboratory, and the reason is because of his abilities.

The Abyss Fragment that fused with him displayed some extraordinary characteristics before granting him his powers. It could temporarily absorb the essence and abilities of Extraordinary Beings, rendering them powerless for a certain period of time.

This characteristic fascinated the scientists in white coats, and they were eager to make it even more extraordinary and weaponize it. Therefore, as the main experimental subject of this project, he obtained the title of Star Devourer, which means he can devour everything from others.
