Archdemon Mammon

What even is this? Supposedly, Archdemon Lucifer is it's father. What the hell? It's a surprise that he could even find someone to intercourse with. Well, it's a thing, no matter how much we don't want it.

History
It began existing as the youngest archdemon once Lucifer got some action. It's speculated that the birth of this thing either was the cause of the destruction of The Proto Realm or it just accelerated the process. I mean, just look at it, it must have been ugly as a baby. That kind of ugly has gotta be universe destroying right?

Anyways, whomever Lucifer got down and dirty with must have been a very good hearted person, because unlike the rest of the Archdemons, Greed did not attack it's creators. This sole reason is why Lucifer abandoned it, and fled back to The Abyss; after all, it is tradition to attempt an attack on your creator in The Abyss.

(You know, now that I read over this again, something doesn't feel right. Well, nothing I can do. On with the article!)

Powering up in Hell
Archdemon Mammon received a vision or something that showed him Ragnarök;Lucifer mode. Needless to say, it scared the hell out of him... so he went to Hell to power up in preparation for that day.

Ragnarök;Mammon Mode
When If Archdemon Lucifer ever regains his full power, he will go on a rampage across the entire Gigaverse until there are two living beings left. And considering Mammon is the closest thing to an Antithesis that Lucifer has, Mammon will be the one to try and stop him. No clue if it will actually work tho.

Gigaradiation Sterilization
A cleansing fire is expelled from Ragnarök;Mammon, which then can completely remove any nearby gigaradiation from existence as well as damage anything related to the Abyss, also he doesn't get hurt even though he's from the Abyss technically. Pretty OP if you ask me.
