Neron[]
Neron is an otherworldly demonic figure, allegedly the ruler of Hell and possibly adjacent dimensions as well. He has personally taken a hand in the affairs of mortals, focusing on disrupting Earth's superhero population. He seduced acolytes by tricking them into accepting a candle, upon the lighting of which, they would gain their fondest desires - in exchange for their souls, of course. Neron used this tactic to empower several members of Earth's super-villain population, giving them additional power, which they would then use to fight their heroic adversaries. Neron's plan ultimately failed as he was unable to predict the purity of heart of Captain Marvel. Neron later went on to combat the newly formed JLA.
