Khaos

"If I had any single regret for the countless horrific events that have transpired in my wake...It's that I'm dying."

- Khaos, moments before being sealed away. Khaos (カオス, Kaosu), more commonly known as Supreme Light Dragon (最光竜, Saikōryū), was once a Dragon of great power, and was known as Dragon King (竜の王, Ryū no Ō), ruler of all Dragons. However, during the great Dragon Civil War, thousands of Dragons betrayed his rule, and with the help of many powerful Mags, as well as many sacrifices, managed to seal away his soul, as his body decayed overtime.

He was recently "revived" by Eva Kiesler, who found his soul, sealed away, and granted him a humanoid body as a vessel, classifying him as a sort of unique case of a Compacted Dragon. Khaos currently remains in her company, until his full power is restored slowly, until he can turn back into his complete Dragon form and break free of his human body, and become Dragon King once more.

Personality
"Right now, you aren't even insects to me. Insects go unnoticed after all. I'll call you the appropriate term, an overgrown monkey."
