Louise Simonson is an American comic book writer and editor. She is best known for her work on comic book titles such as Conan the Barbarian, Power Pack, X-Factor, New Mutants, Superman: The Man of Steel, and Steel. She is often referred to by the nickname "Weezie". Among the comic characters she co-created are Cable, Steel, Power Pack, Rictor, Doomsday and the X-Men villain Apocalypse.

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.
