Necrodolor

Necrodolor is a demon, one of the first ever created. It was an underling of Oni, and the bloodline of the original Dark God, and currently plots to seek revenge against the Tanoshi and AngelWing Dynasties for destroying it's masters.

Appearance
Necrodolor, in it's first witnessed form, is a black sphere of smoke, with three glowing blue eyes, purple, electricity like beams orbiting it, which can become tentacles or tendrils, and a red, diamond shaped core. This core can remain active, even after the body is entirely destroyed.

History
One fateful night, as Novum and Yoki watched the radar, as something seemed suspicious, a small breach was made in the solar system, and what breached was an unknown being. It could not even be classified in a state of matter. Then, the day came when contact was made. A cloud of black gas, with blue eyes and surrounded by purple lightning, descended. It downed several defense fighters and carriers, destroying the bridge between Aureus Regnum and Dragonic Heaven. During the climax of the battle with Oni, the being revealed it was Necrodolor, servant of all darkness. It revealed it suffered from a punishment, causing it to feel all the emotional pain of everyone in every universe. It was nearly killed, but Necrodolor managed an escape. At some later, unspecified point in time, Necrodolor supplied Kuro, its original master, and lord of darkness, with a connection to one of his descendants, a Shadow Minion of Kage. The Dark God was freed, and he unleashed a reign of terror throughout reality itself, Necrodolor leading the Earth invasion. Necrodolor was s spared when Kuro attempted to absorb each of his underlings, due to the curse Necrodolor suffered from. Necrodolor was soon knocked unconscious, and was the only active antagonist to survive. Its current whereabouts remain unknown.
