A humanoid Digimon with a human soul, it is neither wholly light nor wholly dark, but wanders between the two. Unable to become either an angel or a demon, it is both angel and demon, bearing two opposing, mutually repellent powers within its body.
And yet, it became the first Digimon in history to fully control both light and darkness. With twelve wings, more than any other angel-type, it is said to rank among the strongest angel-type Digimon and is known as the god-demon of another dimension.
"Weren't you a guy in your previous life? Even if you weren't pure, why choose Mastemon? Wouldn't falling to darkness be better?"
"Mastemon is normally a DNA Digivolution, but because of my special circumstances, I can Digivolve into Mastemon on my own. Then I can split myself into pure light and darkness, and slowly figure out what to do with the human soul left over. That way, I can freely sleep with Angewomon and LadyDevimon, my two female versions!"
"...If other weaker Mega-level Digimon heard why you got stronger, they'd cry. They really would."
"Who cares about them? The more I think about it, the more I realize I'm a fucking genius."
