Tommy Monaghan was born to Kathryn Monaghan, an Irish prostitute, in Gotham City. His mother had a habit of naming her children after the johns who impregnated her, but Tommy's father was a violent man who threatened to kill Kathryn if she named her unborn son after him. As a warning he burnt down her house, killing three of her children. Kathryn fled to the United States, and left Tommy with a Catholic orphanage in Gotham City. Tommy's father tracked her down and mutilated her. She later died. [1]
Tommy grew up in St. Killian's Orphanage under the guidance of Sister Concepta and Sean Noonan, the latter of which treated him like a son. He befriended Sean's nephew Pat, and the two remained friends into their adulthood. Tommy joined the United States Marine Corps, where he met Natt Walls. He and Natt became friends when Tommy took his side against two corrupt Marine recruits. They served together in Operation Desert Storm in Iraq and saw little action, though they did accidentally kill a group of British S.A.S. troops.
Upon returning to the United States, Tommy became a hitman, and he worked for several mafia families and government agencies. Though he killed for a living, he maintained a firm rule of never killing a good person. This rule came into play several times in Tommy's life as he had encounters with police officers and superheroes. Tommy himself became a superhuman when he was performing a hit on the head of the Dubelz Crime Family. One of the Bloodlines Parasites, the hideous Glonth killed his target, then attempted to kill Tommy by draining his spinal cord fluid. The attack left Tommy alive and able to read minds and see through solid objects. Tommy and Etrigan worked together to temporarily defeat Glonth and kill Joe Dublez. The death of the Dubelz patriarch, however, earned him the hatred of that family.[2]
Etrigan hired Tommy to help him remove Asteroth from power in Gotham City. Asteroth had gotten a religious group called the Choirboy Commandoes to guard him. Etrigan, being a demon of Hell, was not equipped to face them. Tommy was able to decimate the Choirboy Commandoes, as well as Asteroth's thugs, long enough for Etrigan to send Asteroth back to Hell. [3]
During another of Jason Blood and Etrigan's ongoing conflicts, Tommy's services were again purchased, this time by Blood. Tommy was to watch the aged wizard Merlin and kill him if he moved against Blood. Tommy did his job, shooting the man. Blood, after dealing with Etrigan's plot, skipped town without paying Tommy the two million dollars he promised.[4]
Pat Noonan was killed for not revealing Tommy's location to an associate of Moe Dubelz, Tommy declared vengeance on the entire Dubelz family, and he managed to kill every one of them.
The Arkannone, Hell's lords of the gun, were impressed by Tommy's ability to kill so effectively, and they sought to employ him as their earthly agent. He resisted, and the Arkannone sent the Mawzir after him. Tommy managed to kill the Mawzir and the Arkannone with the help of Etrigan. The incident had also led to his on and off relationship with a honest GCPD detective Deborah Tiegel.
Tommy's activities also catches the attention of Mr. Truman, a CIA Agent who despised Metahumans, who also attempted to enlist Tommy to special group in controlling and eliminating the Metahuman population under the interests of the United States; in which Truman ensured that if Tommy rejected his offer then he will be killed while appearing to be resisting a police arrest.[5] Tommy, however, undermined Truman by secretly recorded his conspiracy while under a wire tap and bringing incriminating against him with help from Deborah Tiegel and Green Lantern.[6]
Tommy had several encounters with superheroes and villains. His dealings with heroes often coming at odd ends over Tommy's career, such as Batman. But in some cases can be notably amicable. Amazingly out of those heroes that actually appreciated Tommy and becoming his confidant was Superman.[7] Regardless of Tommy's occupation, he proved himself as a hero when he helped the Justice League in eradicating a Bloodlines Parasite outbreak on their satellite headquarters.[8]
Tommy would again coming into another conflict with Truman over the protection of Maggie Lorenzo, a homeless woman who witnessed an escaped subject of Truman's experiment to duplicate the effects of the Bloodlines incident. Allying with Natt Walls and Kathryn McAllister (a defecting associate of Truman), Tommy destroys Truman's experiment and ultimately leading to a final showdown in which he and Natt were killed but not before killing Truman in the process.[9] Tommy's passing did not went unheard in the superhero community in which Superman was devastated by the news and admitted that he admires Tommy's moral courage in the extreme situation.[8]
