Zero is an outerversal and omnipotent entity that lives in white holes in space (yes, they exist) but is capable of manifesting itself outside of space. When manifesting on Earth, he takes the form of a tall man with a white garment and a white mask with black Enochian symbols (which is considered the hidden language of angels). Zero has a habit of resurrecting the dead, particularly figures whose energies resonate with his, and has been doing so since 2023. Zero does not care about the consequences due to his omnipotence, he transcends angels, demons and reapers as well as his brother Oblivion also transcends these creatures. The fact that he wears white is actually a debauchery to the color white and its meaning.
