Archdemon Lucifer

Archdemon Lucifer is a bird like being that was among the first, of many creatures to come, to be spawned within the darkest and deepest of pits in the Abyss.

Origins
Within moments of Matt Final Orion God Form creating the Abyss, a much larger and more powerful Lucifer struck out against its grand-creator. Matt, being an arrogant son of a bitch, decided to shrink Lucifer for striking against what is essentially it's creator/grand-creator.

His pride having been severely damaged, Lucifer swore vengeance against Matt and life itself, and set out to regain his lost power and size in order to bring about an Abyssal Ragnarök for the entire Gigaverse.

Anime Universe
Any of Lucifer's attempts of invasion into the Anime Universe was ultimately stopped by the barrier that is Fat Asuka. That is, until The 3rd Realm Ice Cream Truck passed by and Asuka ran her Fatass over there, thus leaving the pathway to the Anime Universe open. Though, this event did not leave Lucifer entirely unphased, having somehow been recorded to have said, "Uhhh," before walking right into the Anime Universe.

However, there was yet another barrier Lucifer had yet to face: Saitama. Saitama had punched his way up the hierarchy of the invading Abyss forces, until he reached Lucifer. Not wanting to risk his own life, Lucifer escaped back to the Abyss before Saitama reached the area that Lucifer had been in. Knowing there was another strong being only strengthened Lucifer's resolve to bring about an Abyssal Ragnarök.

Abyss Breath
A blast of Abyss essence. Much of his body begins to radiate a distinct bright blue, that is brightest in his feathers, following which, he "vomits" a dark cloud of abyss smoke, that is spewed toward the target. Lucifer then ignites the abyss smoke with astro fire. The astro fire then slowly turns into a focused, blue beam with overwhelming power, enough to slice through dwarf planets.

Ragnarok;Lucifer Mode
When Lucifer finally regains his true power, he will go on a rampage across the Gigaverse eventually dying out when there are only two living beings left. Too bad he's too much of a pussy to actually do any of this.

Galaxy Eating
Due to his very large size, Ragnarok;Lucifer requires gigantic amounts of energy to sustain him. Thus, along with his goal of exterminating of the Gigaverse, eating galaxies furthers his progress and supplies him with energy.

Gigaradiation Breath
Having been rendered as physically blind, Ragnarok;Lucifer is able to expel clouds of gigaradiation without any disability.
