Entropy is one of the four Kherubim Lords that crash landed on Earth over a millenia ago. In the middle ages, he ruled over the mystical city of Shangri-La. During this time Entropy allied with another of the Kherubim Lords, his brother Emp. Together they battled against Brannoch the Dark, a man possessed by a daemonite; the Kherubim's most hated enemy. Upon confronting one another, Entropy slew Brannoch. The daemonite possessing Brannoch managed to jump into a new host during the battle, taking over Entropy's lover, Gwynith. Entropy could not find the resolve to kill his lover which forced Lord Emp to carry out the deed. In the aftermath, Entropy became enraged and vowed to claim revenge on his brother.
After Emp founded the WildC.A.T.s, Entropy would appear to take revenge for the slaying of his former lover. Entropy attacked a cruise ship that Emp was on in order to capture him. Due to Emp's memory loss at the hands of Helspont, Entropy used his Orb of Power to restore Emp's memories. Before Entropy could collect on his old vow of revenge, the WildC.A.T.s appeared and stopped him. It is believed that Entropy died in a very large explosion resulting from the conflict.
Like most Kherubims, Entropy is an immortal. His long life span has allowed him to train in various combat methods. As a Kherubim Lord, he also possesses certain powers similar to his brother Emp such as super strength and energy manipulation. During his conflict with the WildC.A.T.s, Entropy was in control of an Orb of Power which greatly enhanced his natural abilities as well as allowing him to defy the laws of nature and probability.
