History: (Comics) Billy, was a boy who wanted to be the greatest villain of all, and began his self taught class in being a villain, by competing with heroes his own age. Billy (Harm) kept a "Book of the Blood", his own database of the powers of the heroes he's battled with. His parents, Burt and Ellen fear him. There boy is a super-villain in training, and he is good at his job. Harm was not a normal child, his father citing an incident with his son, carries with him, a scar on his neck, that one inch closer to the left, would have severed his jugular. They wanted there boy to be disciplined or disappear, they were afraid, and they were justified. As Harm returned home one night, he found his mother and father waiting for him, his father, trying to express some discipline and enforce a curfew, was met by the chilling return comment of, " Father. I allow you and mother to live."

In his first appearance, we see Harm, single handily beat Arrowette. Physically, returning one of Arrowette's arrows back through her own arm. Leaving Arrowette to pass a message to her friends and other teen superheroes alike, "stay out of Harm's way."

After hearing of Harm's warning, Superboy took off on his own to find Harm, and take him out himself, must to the disagreement of Robin and the rest of Young Justice. Unfortunately, Superboy was a little too late, as he caught up with the beaten Wonder Girl and Secret. In his (for lack of better term) Harm-mobile, Harm, again, beat not 1 teen hero, but 3. Using electricity to finish Secret, Harm kept Wonder Girl off-guard by slamming her face first into a bridge. Wonder Girl's only save turned out to be Superboy himself as he tried to take on Harm by himself, only to fall before Harm, seconds later . Harm, using some sort of special gas, which filled the lungs of Superboy, making him an easy target to knock out and defeat. With some parting shots with Wonder Girl, Harm left the heroes, so that he could avoid any contact with the police. Harm was victorious.

The next time, we see Harm, is as he, already broken into the Cave, seemingly kills Red Tornado, by ramming him through with his sword, only to take him, and reprogram him, to help in his plot to kill the Pope. Leaving a clue as to where Young Justice could find him, Harm carried out his plan, to only be stopped and confronted by Young Justice. Again, Wonder Girl fell beneath the power of Harm. But it came down to a one-on-one battle with Robin that ended in Robin's defeat, but a mistake on his part, and a save by Arrowette sent Harm over the top of a cathedral and into the body of Impulse, who was carrying the bomb, that Harm himself planted within the body of Red Tornado. Using the bomb's explosion, Harm, again escaped the team, but did not accomplish his mission of destruction.

Billy, returning home, was met by his father, whom he again challenged to discipline him, and again, intimidated his father, and mocked him again. This time though, his father had another thing in mind. As Billy entered his bedroom, his father, pulled the trigger, and shot his son, straight through the chest. Billy crawling from the bedroom, was met by his father, smoking gun in hand and tears in his eyes. "I promised you mother, I'd handle it." Burt, then apologized to his son, and again, pulled the trigger. The last panel we see is "Blaam".

Harm would later return (Young Justice #14) during the "Day of Judgment" crossover. The events of Hell freezing over, would give Harm an escape from death itself. Secret herself also felt the ramifications as Suzie herself in front of her Young Justice teammates completely froze over. Before the team could ask on it, Secret's ice form exploded reveling Harm. Explaining that Hell had frozen over, Harm again went into dominating the Young Justice team, eliminating Superboy and Wonder Girl. After a few minutes of Secret pulling herself back together, she found out that she recognized Harm. Harm and Secret are brother and sister. Both dead. Harm killed by his father. Secret a sacrifice by Harm. Secret quickly send Harm flying out of the cave. Outside of the cave Wonder Girl and Superboy double teamed Harm, giving Robin and the Super Cycle an open shot. Secret screaming "This time... we die together", quickly launching herself into the mountain and into Harm, creating an avalanche that covered them both. After hours of waiting for either Secret or Harm to appear from the avalanche, Impulse went in and scouted out the area but couldn't find any sign of either Harm or Secret. Harm's current location is unknown. Secret was found to be in custody of the A.P.E.S. and was rescued from there grasp (Young Justice #17).

(RPG) *Full origin details in In The End Pt. 1 and In The End pt. 2*Acolyte chose to bring Harm back to life to be the new God, but upon failing was cast aside for Doomsboy. In a fight with the clone, Harm was beaten to the point that he lost his memory and in his injured state joined the Titans. Shortly after he got his memory back and helped the Titans to overthrow Acolyte earning his place on the team with his former enemies...okay he's actually serving his jail time by being a member of the Teen Titans and if he steps out of line the All Purpose Enforcement Squad(A.P.E.S) will throw him in jail so fast it'll make his head spin. But chances are that won't be a problem since he's fallen in love with the one who found him when he was injured, Wonder Girl. They're friendship steadily grew into a relationship and she's become almost his lifeline as far as keeping him a good guy.

After a series of incidents with him trying to fight his dark side, Wonder Girl couldn't take it anymore and dumped him. Seeing that he had no other alternative, Harm performed a ritual designed to get rid of all of his demonic connections. While this worked and him and Cassie did soon get back together it also left him vulnerable. Soon he left to the mountains of Tibet, to find the White Mage, who trained him in the use of basic white magic giving him a means of defending himself and resuming his superhero life as Harm.

Updated History: After the events of Into The Fire and Decisions Decisions Harm felt that he had to go back to Hell to get his demonic connections back. But of course things didn't go exactly as he planned and he ended up getting his powers back and much more. Instead of merely getting his connection to his previous demon sponsors, after two years of torture in Hell, Satan gave Harm a new body composed of the former sponsors. No longer human, Harm tries to keep his demonic body trapped away in a human shell (The equivalent of holding a telephone book inside of a tennis ball), so far only a few people know Harm's now completely demon, Duo, and recently Cassie.

Powers: Super strength, speed, healing abilities, energy blasts, and growing knowledge in magic.

Weaknesses: Harm is almost always in a state of pain as long as he's in his human form as well as having a harder time fighting his primal urges now that he's a demon.

(Previous information updated OYL)

Updated History: After a series of events(see One Step Closer and Harm:OYL, Harm ended up meeting his half sister, Mortem who was the previous of the six before him and after an inevitable fight Harm came to the conclusion that he was sick and tired of villains that'd been taken out coming back for more getting stronger each time (IE: Rip, Vicious, Hellfire) and the easiest way to take care of that would be going against the Titans' "no killing" rule. Though this decision is a well kept secret, only known by Duo and Secret.

Also because of the way of the Eldrich(Mortem's people), defeating her put Harm in charge of the human hating race effectively stopping an invasion that would have happened soon. Soon afterwards Harm ended up getting fired from his old job at the music store but being offered another one by the DEO(Department of Extranormal Operations) which involves hunting and if need be, killing demons. Though he has a strict no humans policy as far as that goes.

Updated Weapons: Purgatory- Previously Mortem's sword, inside of it is encased a demon that will absorb the soul of anyone who touches the sword besides Harm, Wonder Girl, Duo and Secret. The same effect happens if enough blood is shed with it.

Updated Weaknesses: While Harm is getting a better handle on his demonic form (enough that he can be unconscious without changing), he's still having some issues keeping it back if he's fatigued enough.
