While monitoring the works of his mystic unit of the Voyagers, Vincent noticed them summoning something powerful. It turns out to be a demon Mini... A rather HUNGRY demon Mini. So hungry, that she almost immediately attempted to eat everything in sight. Vincent's Minis managed to subdue her and gave the Mini a proposal: if she behaves, then she can eat as much as she wants. Thus, that is how Damona came to be.
As stated before, Damona is hungry. REALLY hungry. She'll eat anything and everything that is edible. If Roza didn't have her in check, she might end up eating everyone! Thankfully, she's in check about just in case that would happen. As for her personality, she acts pretty much like a child, curious about anything she sees for the first time. Sometimes asking about its taste.
In battle, her eating habits are shown just how tremendous they could be. She'll gladly take a bite out of anything or anyone that looks delicious. She's pretty ravenous. Don't believe me? Her Ultimate Move will prove it to you.
Dark Crunch: (Dark|Physical) Chomps onto the opponent with a ravenous bite. May cause the opponent to flinch.
Spirit Sap: (Spirit|Special) The user drains the life force of the opponent to restore their own health.
Shadow Blast: (Spirit|Special) Fires a spectral blast at the opponent. May lower their Attack.
Drag Down: (Dark|Physical) The user brings the target down to their level with a fierce attack. This move eliminates any raised stat the target has.
Ultimate Move: Shadow Maw (Dark|Special) Damona opens her mouth to pulls the opponent in a vacuuming force, resulting in them trapped a dark dimension... which is actually Damona's stomach. They have to do enough physical damage for three turns to break free, or they'll suffer a OHKO.
