Well, Damien was/is the main antagonist of the first Fanfic I was doing.. A little about him;

The second born of the dragon king,

Master of Draconion magic,

Guardian of the Gate of Lust for Spike’s bloodline,

Manipulative,

Fears only the dragon king himself,

He taught Spike how the life cycle of dragons worked, taught him how his gren slame was magical in nature and could produce hypnotic affects on anyone he walks within the vicinity of the illusionary flames.

A ability Spike tested by placing 5 of the main six into a unconscious state while completely disabling Twilight both Physically and mentally. Even denying her the ability to speak during their one sided conversation.
