So for those who don’t know, the Power Pack is a team of 4 super powered pre-teen siblings, created by Louise Simonson and June Brigman and first appearing in Power Pack Power Pack #1 in 1984. The Power Pack have shown up again some revivals and new appearances over the years, most notably with the All-Ages series in the 2000s, but they have sadly not been adapted at all in other media, outside of the failed 1991 pilot and a few cameos and mentions.
I think there’s a lot of potential for a Power Pack series, more specifically an Animated Series. As for the series’ premise, it would be typical, following the adventures of the 4 siblings (Alex, Julie, Jack and Katie), as they faced off against threats old and new, while also dealing with their regular civilian lives. Your typical superhero team series. Maybe with some guest appearances by other marvel characters as well.
