Eclipso

Eclipso was a supervillain and an enemy of the Justice League of America. He was originally the Spirit of Vengeance, until he rebelled and became evil, using his demonic form to possess various humans.

At that point, Spectre became the new Spirit of Vengeance, and Eclipso had became a demon. During the 20th century he possessed a man named Bruce Gordon; taking over his body every time an eclipse occurred on Earth, hence the name Eclipso!.
