Zom's creator is a mystery but it is known that he was created only to destroy. After his creation he rampaged untill a powerful magic user fitted him him with The Crown of Blindness and The Manacles of Living Bondage and trapped him in a jar. Eons later, Dr. Strange was confronted by Umar and the only way to defeat her was to release Zom and use his power against Umar. This worked but Starnge then need the help of The Living Tribunal to destroy Zom. A tiny fragment of Zom was recaptured in the Jar and is under Strange's watchful eye.
Marjor Story Arcs
World War Hulk
During World War Hulk, Dr. Strange called upon Zom after having his hands smashed by Hulk. Dr. Strange accomplished this feat and was taken control of by the entity who ultimately ended up being defeated by The Hulk and was exorcised from Strange's body by Hiroim.
The Chaos War
During The Chaos War, Zom returned as a thrall of The Chaos King and was given control of Doctor Strange's body once again with help from his new Master. The Chaos King gives Zom and the Abomination the mission to find Marlo Jones, and get a spark of Death out of her. To do this Zom uses Strange's boby to lure the Hulks to earth and tricks A-bomb into reveling where Marlo is hiding.
Together, Zom and The Abomination attacked the bewildered Hulk and his allies and then flew away on the backs of demons to Marlo's current location. Zom and The Abomination were later seen descending from the sky, ruining a tender moment between Betty Ross and the newly resurrected Glenn Talbot.
A fierce battle broke out between the group, who had now added Jarella, Talbot, Hiroim, Doc Samson and countless undead soldiers from various time periods equipped with Ion Cannons to the fold, and Zom found himself fighting Skaar and Hiroim who, together, managed to take Zom down using The Old Power.
That is until The Abomination summoned another trump card, in the form of Brian Banner wielding the power of The Devil Hulk, to aid them in their struggle. Zom later managed to subdue his opponents and get his hands on Marlo and forced her to unleash Death, whose power Marlo used to kill Zom and The Abomination.
Zom is one of the most formidable mystic entities in existence, referred to far exceed even Umar in terms of sheer mystical power, and thus presumably her brother Dormammu as well, if not by quite as much. The Living Tribunal once stopped him, although Zom greatly feared the Tribunal.
His head was adorned by a long tuft of hair, like a topknot, which apparently acted as a perception shield, masking his presence from other sorcerers.
