"Eclipso wreaks havoc and chaos by possessing others to carry out its evil deeds and feeds off the hatred and desperation of its victims' corrupted souls."

Cindy finds a black diamond, formerly owned by William Zarick (aka The Wizard). It contains an ancient entity that is the incarnation of the Wrath of God and the Angel of Vengeance: Eclipso (Nick Tarabay). When activated, the diamond comes alive and emits a blue-purple glow.

In S2E01 there is a flashback where Eclipso possesses Bruce Gordon, who uses the diamond to kill Rebecca McNider, the 10-year-old daughter of Dr. Charles McNider (aka Dr. Mid-Nite).

Cindy thinks that she can control Eclipso and enlists it as her ally. However, in S2E02 it possesses her and kills her stepmother, Bobbie Burman.

Who will be Eclipso's next victim?

Yolanda (aka Wildcat)? Beth (aka Dr. Mid-Nite)? Or...

"He is the devil in the shadows."
