Royce is a Lobotomy Corporation oc that i've evolved overtime while following Project Moon's other games and molding him to fit properly into its universe.
He self-indulgently came into existence when i got obsessed with the designs of the Apostles within lobcorp/ruina. It's essentially the concept of ; "What if the deemed "Heretic/Devil" wasn't spared from transforming into one of them?"

TECHNICALLY, he's categorized as an ALEPH, however (1: he's a little bit pathetic and too nice to use his strength to maliciously hurt people) and (2: the transformation fucked up a lot of his insides and general body formation, which gives him various health issues to deal with to balance things out.)
He is traumatized by his encounter with WhiteNight and has both developed a deep hatred for said abnormality while at the same time fearing its presence just as much.

Royce is deeply rooted in the concept of religious trauma, and the things it envelops.
