1. Someone like Champion of Cyrodill, who can beat everybody with a sword. Like in other games that are very badass and can kill armies with their fists. But are mortal, but they skill levels make them unstopble.
2. Someone like Voldemort or Sauron, that can kill 20 enimies with a single weapon slice and are immortal because of some kind of universe rule or object.
3. Someone like a Dragon. Who can make cities fly with a Fus RoH Dah
4. Citie Busters like in Dragonball. Those who can destroy cities (such as Mehrunes done in LORE) with an energy ball of the size of an insect.
5. Someone who can change the things with a think because of what their represent. For example, since Azura is the Deadric Prince of dusk and dawn, she can change the day time as she wants as well Hircine, that can summon like 10.000 animals to atack a city. Or like the Olimpian gods in God of war, that can use water and sky as they want because of what they represent.
6. Someone with the powers similar of Galactus, Alduin looks alot like Galactus because of his powers. When he tried to eat the planet, alot of major powers needed to act agaisn't him. Such agaisn't Galactus. This level they can control alot of the things that surround them on an insane scale.
7. Some one like Pre-Retcon the Beyonder of Doctor.Manhathan. But this is a very ridiculous and imporbable because they can control mater and the universe that surround them with what they can think. Sithis of the monomyth would be the closest to this.
8. Someone like Chuck Norris, well how can i describe Chuck norris powers?
"Sithis exist because i demanded."
