Alex is the son and first child of Margaret Power and James Power, an inventor who once made a device which (unbeknown to him) could destroy large parts of the universe. The alien race known as the Snarks came looking for the device and thus came into conflict with the Power kids, whom moments before had received amazing powers from Whitey, an alien who died trying to warn the Power family of the nearing danger of the Snarks. Alex was given the power of anti-gravity, which enabled him to make himself and other persons/objects weightless.
His younger siblings also gained super powers: Julie could fly, Jack could manipulate his body density and Katie could disintegrate matter and then fire energy balls. Alex adopted the code-name Gee (most likely as in G-force). Although they four of them now had amazing powers, they could not stop the Snarks from kidnapping their parents and taking them of into space for further study of the humans.
All seemed lost until the smart-ship (named Friday) of the now dead alien Whitey told the Power kids he could follow the Snarks and try helping them rescue their parents. The foursome went of to outer space, in hot pursuit of the Snarks. After an intense battle the Power Pack found their parents on the Snarks mother-ship, where able to save them and flee the forces of the Snarks. After-wards, Alex' parents didn't have any memory of the Snarks or their kidnapping. The four siblings decided to keep their powers a secret to their parents and the world, and thus Power Pack was born, world's youngest superhero team.
Alex Power was created by writer Louise Simonson and artist June Brigman and first appeared in Power Pack #1 (1984).
Power Pack soon established itself as a young superheroes team, with Alex being their unofficial leader. Mainly because he was the eldest. They had their own costumes and often teamed-up with other heroes, working with larger superhero teams, like the X-men and the Fantastic Four and they even became a trusted sight for the amazing Spider-man. Early in their careers, the team befriended Franklin Richards, who came looking for the team after he had precognitive dreams of Power Pack getting attacked by the Snark prince Jackal. These dreams turned out to be a reality when the team was in fact attacked by the Jackal. Power Pack, aided by Franklin, fought the Jackal in a lengthy battle and won. After this, the team accepted Franklin as a member of the team, codenamed Tattletale.
While Power Pack was doing battle on the Snark planet, the team went through their first 'power switch'. Team members could 'trade' their own power for one of their brother's or sister's. Alex gained Katie's old power, the disintegrating power. He could disintegrate objects and fire energy balls. Besides the fact that they could now change powers at will, the team also found out that they had a more then uncanny ability to heal faster then any normal human could. The next time the team switched powers, Alex got his original power back, but started calling himself Zero-G instead of Gee. Alex and his brother and sister's went on to battle many more menaces like the supernatural Bogeyman, but also more earthly subjects as drugs-dealers and robbers.
After many, many adventures the Power Pack team decided to take it more easy and start living their normal lives again. This worked out for most of the time, except when Alex briefly returned to the superhero life, aiding the New Warriors. Alex was recruited by both Bandit and Hindsight in order to help stop the Sphinx and rescue the time displaced Warriors. He borrowed all of the team's powers, making Alex stronger then ever and naming himself PowerPax. He initiated a power-transference from his siblings in order to be a greater help to the Warriors without the need to involve the rest of the Power Pack. Afterwards, he returned their abilities back to them and promised not to take them again, but was later forced to reclaim them again to aid in the Warriors' battle against the Soldiers of Misfortune. Eventually, Alex explained to Julie and Jack his reasons for taking the Pack's powers into himself, which angered his siblings, especially Jack. During Alex's tenure with the Warriors, he had encounters against Spidercide, a brief fight against Psionex (with then Night Thrasher and Rage on said team at the time), Protocol and the Soldiers of Misfortune, and both the Sphinx and Advent. Alex's final mission with the Warriors was when they fought the Dire Wraith, Queen Mother Volx, (who had already stolen the Torpedo suit from Mickey Musashi, Power Pack's Smartship Friday, and Rom's Neo-neutralizer). The team succeeded in destroying her plans (along with the Dire Wraith as well), but at the cost of nearly destroying Friday, Power Pack's old smart-ship and friend.
The 2000 mini-series
Soon after this peace returned to the Power's house. Alex was attending high school and started noticing the girls around him more and more. It looked like a time of peace for Alex, in which they could fight as the Power Pack team, but also enjoy their normal lives. To protect their identities Alex and his brother and sisters now whore masks whenever they appeared as Power Pack. The team had to return to their old alter-ego's again when the Snarks attacked their home. A battle was fought but the kids managed to defeat them once again and save the day.
Alex has been identified as one of the 142 registered superheroes who are a part of the 50-State Initiative and reported training at Camp Hammond. Alex is now known as Powerhouse.
While both Alex and Jack where attending a birthday party for Franklin Richards Alex was invited to join Mr. Fantastic's new Future Foundation, a group of some of the best young minds. Alex contributed to forming the chemical that would allow the Thing to turn human and also fought alongside the Thing and Human Torch when the Baxter Building was invaded from the Negative Zone. He was there when Johny Storm, aka the Human Torch seemingly sacrificed his life in order to stop the invading army from the Negative Zone to reach earth. Alex is now a member of the team that replaces the Fantastic Four after the Human Torch's death, named the Future Foundation. He was joined by a group of young students, as well as the now smart Dragon Man.

After this, Reed Richards, standing on the brink of all creating together with his family and the Future Foundation, decided to restore all of the multi-verse and asked eveyone if they wanted to help him with this task.

Alex aksed for her help and, with not much consent, teleported Julie onboard of Future Foundation ship.
