Omnius is an entity that possesses ultimate power, with abilities that cannot be nullified. He is resilient, unyielding, enigmatic, Charred and Eternal, and has complete control over the universe's energy and every aspect of reality. He can manipulate time, control dimensions, control the void, read and control thoughts, and erase enemies from existence. On the other hand, Sans is funny, makes puns, and relies on magic attacks and teleportation. He is outmatched in every aspect by Omnius, who possesses incredible magical and physical strength, and cannot be erased, as his abilities are far too powerful. In this battle, Sans would be no match for Omnius and would ultimately fall to his overwhelming power and control over the universe.
