Origin

Power Boy was raised in the planet ruled by Darkseid known as Apokolips, the place where he once lived was the slums of Armegetto, however he would be later taken from his home because Darkseid had plans for him. One was to train him and the other one was to use him as a weapon.

It was then that he discovered his abilities to create great power from his hands thanks to the emotions he felt, for example love and hate. He also discovered that he could use the same ability with the emotions of other people.

Meeting Supergirl...without her knowledge

Some years later, Darkseid would capture and brainwash the newest incarnation of Supergirl in an attempt to use her as a weapon against Superman and the Earth.

It was during this time that Powerboy saw for the first time Supergirl, it was love at first sight which leaded him to go to Earth in an attempt to meet her.

DC's missing year

After the events of Infinite Crisis the DC Universe jumped an entire year of continuity. It was during this "lost year" that Power Boy would join along with Little Barda the Teen Titans.

After the death of Superboy (Connor Kent), the fact that Cyborg (Victor Stone) was in a coma and Robin (Tim Drake) was in a trip around the world with Batman (Bruce Wayne) and Nightwing (Dick Grayson) left the Teen Titans in a time of crisis. Beast Boy decided to start a membership drive for new and old members to join the almost broken team.

However just after the encounter with the newest incarnation of Infinity Inc. and the death of one of their members thanks to the new Blockbuster, Powerboy and Little Barda left the team.

Supergirl

Some time later and after failing to get a secret identity, Supergirl would try to join the Outsiders. It was during a mission that went very wrong that he would be saved by Powerboy. The atraction between the two of them was obvious and after a few missions together (not as members of the Outsiders) they started to date.

However the most they spent together, the most possesive Powerboy became about Supergirl. Also in an attack of jealous he hit Supergirl saying that it was all her fault and that he was just saving her.

When she woke up he found out that he was obsessed with her and had a wall of images of her, after that he explained to her about his origin, his powers and the reason he attacked her. Supergirl didn't care and after burning his hand with her heatvision she told Powerboy that their thing was over.

Death

We see Powerboy some time later as a member of Cyborg's new Titans East team. Along with Little Barda, Lagoon Boy, Son of Vulcan, Anima, Hawk and Dove they started a training session.

The objective of the training is that everyone had to team up to defeat Powerboy who was the powerhouse of the team.

After a little confrontation with his team-mates and being thrown into a forest nearly the rest of the team find a dead and burned Powerboy stabbed in a tree, after that the rest of the team is attacked by a mysterious force which leaves the rest of the team in the floor unconscious and maybe even dead. Powerboy is the only character that is confirmed to have died after the attack.
