Empireo

Also known as "MP", "EMP", "emps", "empeanus", "the wun tep man", "the deagle master", "the respectable awp-man" and "perry-perio"

Formerly known as "Empi".

 Known facts and history: 

Is very fond of his get-rich-quick scheme titled "The Smegmug".

Has, on several occasions, spent multiple hours describing in exhaustive detail all of the ways he wants to cum inside every single one of 2B's holes. At the same time.

Self-proclaimed "NieR master", complete disregard of his inferiority in this department. This behavior might mean Empireo has a tendency to be delusional. For the true NieR master, see SoBeta.

Can survive solely on cat food.

Has a band called "MP and the Rs"

 Current theories and speculation: 

Empireo backwards spells oeripme. If you look closely, there's a secret message; "O.E. RIP me". This is undoubtedly a secret message from Empireo, warning us that his life is in danger from whoever "O.E." is. So, who is O.E.? To understand that, first we need to look at the shortened version of Empireo's name: Empi. "Empi" when said aloud sounds like "MP", which also rhymes with "OE". If you put the letters together, you get MOPE. There's another clue in Empi's name too. What does MP stand for? Member of Parliament. And what does a Member of Parliament do? Democratically represent their electorate. The key word here is "Democracy". Now, if we cross-examine the word "Democracy" with the word "Empireo", we find they share many letters in common. If you remove the shared letters from "Democracy" you get "DCACY". Now lets remove the letters that turn up twice to get "DAY". What's the opposite of day? Night. What's it like at night? Dark. What does darkness and democracy both have in common? They both begin with the letter "D". So, let's add D to the word MOPE we had before, to get "MOPED". Could O.E. be related to a moped accident Empireo was involved in in Italy many years ago?

But the rabbit hole goes deeper.

If you look closely at the word "Empireo" the more observant might notice the letter "i" in the middle, surrounded by three letters on either side. Who else has the letter "i" in their name surrounded by three letters on each side? That's right, guhinim. So this begs the question, does guhinim like mopeds? If so, we may be one step closer to uncovering the mystery of O.E.

The investigation is ongoing.
