A dude from the Warhammer 40k universe. Twentieth son of some magnificent shiny dude who's in charge of everything, the primarch of the Alpha Legion of SPEEHS MARINES along with his twin brother, Omegon. Everyone has an obsession in pretending to be him because his legion is specialized in manipulation, covert operations and pretending to be Alpharius.
Random dude:" I am Alpharius!"
Another random dude:"No, I am Alpharius!"
