Damien is kind of an asshole. He serves as an antagonist in the way that he foils with the main character Asher. Similar to a rival. He feels that he's right in most situations and Asher is constantly screwing things up for him. He's constantly lashing out and has anger issues. He struggles with understanding everyone else's emotions and also tends to rule with an Iron Fist.

He's the ruler of Nightgrove and lets everyone know it. He's prideful, loud, angry, and arrogant. But, when things do get crazy when things do get lost and hopeless, he is able to find the good in himself and stand up for people.

Damien sounds angry, loud, and over the top a lot of the time. He's very condescending. I think I'd relate his voice the most to Bakugo from My Hero Academia. So yeah this role is a tough one.
