Deimos "The Shocking Sorcerer"

Since he was a child, Deimos knew he was different. He would be able to hold a light-bulb in his hand and make it shine brighter than it ever had, until the filament exploded. He hails from the cosmos, and has otherworldly erratically lightning that sprouts from his form. Little is know about him, save for the fact that he is not of this world, and should be revered as a challenging opponent...
