Power Pack

Power Pack is a superhero team consisting of four young siblings appearing in American comic books published by Marvel Comics. Created by writer Louise Simonson and artist June Brigman, they first appeared in their own series in 1984, which lasted 62 issues, and have since appeared in other books. Power Pack is the first team of pre-teen superheroes in the Marvel Universe and the first team of heroes in comics to feature characters of that age operating without adult supervision. In 2005, the title was relaunched as a series aimed at younger readers—though this was eventually declared a separate continuity from that of the original series and the mainstream Marvel Universe.

The team consists of four siblings: Alex Power, Julie Power, Jack Power, and Katie Power. The dying alien called Whitey, a scientist of the Kymellian race, transfers one of his four superpowers to each of the Power children so they can save their planet from the alien conquerors known as the Snarks. The children band together as the superhero team Power Pack. Along with fighting aliens and super-villains, the team's stories were known for focusing on morality debates and social issues such as child abuse, homelessness, drug abuse, bullying, and the ethics of using excessive or lethal force in combat.
