Power Pack is a fictional team of superheroes consisting of four young siblings appearing in American comic books published by Marvel Comics. They were created by writer Louise Simonson and artist June Brigman and first appeared in their own series in 1984. The series lasted 62 issues. The characters have since appeared in other books. Power Pack is the first team of preteen superheroes in the Marvel Universe and the first in comics to operate without adult supervision. The title retains a cult following and in 2005 was relaunched as a title aimed at younger readers—though this was eventually declared a separate continuity from that of the original series.
