Power Pack

[close] Alex (age 12), Julie (10), Jack (7), and Katie Power (5) were bright, normal American children living with their parents in a beachfront house in Virginia. Their father, Dr. James Power, was a brilliant physicist who discovered a process to generate energy from antimatter with the assistance of a converter, of which he made a prototype. An error in his formula, which could have caused a chain reaction and destroyed Earth, was discovered by Aelfyre "Whitey" Whitemane, a member of the Kymellian race, who resemble humanoid horses. A similar accident destroyed the Kymellians' home planet.

Whitey tried to stop the experiment by warning the Powers, but was mortally wounded by his enemies, the reptilian Snarks, in the process. The Snarks kidnapped Dr. Power and his wife, Margaret, hoping to obtain the secret of antimatter. Whitey rescued the Power children and told them what was happening. Before dying, he passed his powers to them to complete his mission.

The children, with the help of Whitey's "smartship", a sentient starship called Friday, managed to stop the antimatter test by stealing and destroying the converter and rescued their parents from the Snarks. They decided to continue being superheroes and to hide their powers from their parents. Alex took the codename Gee, Julie became Lightspeed, Jack became Mass Master, and Katie became Energizer. They wore costumes made for them by Friday, which were actually Kymellian spacesuits. The costumes, which were constructed of unstable molecules and stored 'Elsewhere', could materialize and disappear on voice command.
