Azure's 6th dragon- Helldragon Necros or Necrosan as his full name.

Left Side (with Azure): Ghost form
Right Side: Bio (true) form.

"Long ago, I asked someone who was sneaking around my home if they were afraid of me. They said no. I asked them why. They told me I was beautiful."
~Necrosan, citing how he became Azure's dragon.

Resides over: Darkness

Abilities:

-Dead Zone: Everything within a set radius around Necrosan is encompassed in darkness; the Dead Zone. In this zone, he has control over the thoughts of things ranging from nature to the dead, which he can raise if there are any. He manipulates and magnifies their thoughts of malice and hatred, pulling them under his influence. Within the Dead Zone, all plants and wild animals with a weak life force wither and die. He can also steal the life of beings under his control and use it to amplify his own.
-Decrepit Blood: Necrosan's blood, which is blackish-purple in color, can be used as a biological weapon. Toxic and disease-ridden, he uses it by vomiting it at his enemies, aiming for open wounds specifically.
-Noxious Breath: Necrosan exhales a very foul odor, due to his decayed body. He can use this to knock out and incapacitate enemies.
-Vampire Breaker: Necrosan drains the life force of all of his minions and channels it into a concentrated ball of energy between his tusks and maws. The ball is fired as a long-range energy weapon.

Random note: Necrosan's mouth is indeed closed in this picture. The front portion of his lower jaw is broken and just kinda dangles there. :/
