The series starts off with six kids finding out that their parents are supervillains who work for the crime organization The Pride. The kids--whose ages range from sixteen to ten--decide to flee their families and band together instead. However, their parents are tracking them and one of them is a traitor. It's a very original Marvel story. Instead of buff Avengers-types, there are a bunch of bumbling teenagers who barely manage to scrape by in their fights. They survive off of junk food, hide out in junkyards, struggle with leadership, and come to terms with their parents' crimes. Vaughan provides the story with a lot of heart, and makes it one of the funniest and heartbreaking graphic novels I have ever read.
