Suntsitzeagal

Suntsitzeagal (commonly referred to as The Nidhoggr) is the collective force of all the stupidity, despair, and dying imagination of every sapient being in creation. Its essence surrounds all universes, waiting for when they become stagnant so that it can invade the universe's weakened state and steal all life and vitality from it, leaving behind a withered, broken husk of a universe.

Omni 01
Sunt hasn't interfered in the actual Omni 01 universe yet, but in many timelines that "I" has had split from Omni 01's main timeline he has appeared. He also often devours pocket universes surrounding Omni 01 in order to get closer to the actual universe.

Erudite 01
Sunt almost arrived in Erudite once, when the Moroitos Empire there was at the peak of its power. He had actually started devouring the universe, as many planes (especially the plane aptly named "Creation's End") show signs of. However, the combination of the Demons destroying the Moroitos and a brave hero physically banishing him from Erudite and strengthening the boundaries of the universe were able to stave him off.

Power
Sunt's power source is the stupidity and death of imagination occurring throughout all of creation, sped up by their despair. As he is in a constant battle with I|The Titan King "I", his powers vary greatly. He is always able to devour universes, prying one those weakened by stagnation to feed on the energy of everything within. The result of this is a universe full to the brim with choking dust, with the shattered remains of some planets all that's left of what was once a universe full of life. At the peak of his power, he also has many other abilities, though these are mostly instinctual and are always used towards his goal of devouring all of creation.


 * Sunt is a Level 9 being. He can devour entire multiverses and the materials needed for the other Titans to return life to the universe. Materials from an alternate universe or few are needed in order to fully revive a universe devoured by Sunt.


 * Sunt can take control of any being he desires, whether it be a Titan or a mortal. He can create an avatar for himself in order to further his goals in a certain universe.


 * Sunt can technically breach the fourth wall itself and recognize that Omni 01 is actually a multi-user wiki, though he is not smart enough to do this.
