Skills and Abilities
Strengths: Is probably the second strongest of his family, not that this is much to go by.

Special Abilities: All magic.
Weaknesses: Sunlight: They are not allowed to be exposes to any form of light. Even the tiniest touch of candlelight can severally harm them. This is why they are only allowed to leave at night, and why they chose to avoid any FireWing.

Unable to Leave: The demon children cannot leave Nightflare, for they are bound to her soul, and unless their physical body is destroyed, it will remain that way. They have to stay within a twenty mile radius of her. The loophole to this is that they can stay in the den, no matter how far away Nightflare is, but they cannot leave the den if Nightflare leaves their radius.

Magic Sickness: These demons can become incredibly sick if lacking in, surprisingly enough, socialization. Demons feed off of misery and souls, and if they aren't exposed to a host, they can quickly die. This is why the children try to stick very close to Nightflare, so they can feed off the negative energy coming from mortal dragons. If they are left without this nutriance for just three-twenty hours, they will die.

Recharge: Demons also become weak when inside of a mortal body for to long, so they are also physically weak, and would easally be beaten by even the weakest dragon
Combat Style: He will try to eat his opponent.
