He was an ancient demon of destruction, defeated & sealed away by angels. He was awakened by Maarkus Thompson to create a distraction, but was defeated by the Ancient Alliance and was infused in Jonathan Thompson. While in Jonathan, Smoke tried to take him over but constantly failed. Jonathan tried to reason with him about being good and succeeded. Being inside of Jonathan for a very long time, enabled Smoke to gain some of Jonathan's characteristics, abilities and personality. He aided Jon in his hero days and was the reason why Jonathan became evil and a member of the Anti-Five. When Jon reverted to his normal state so did he. Smoke vanished when Jonathan was killed by the Dragon Empire.
