Originally, the series featured a group of six kids whose parents routinely met every year for a charity event. One year, the kids spy on their parents and learn they are "the Pride", a criminal group of mob bosses, time-travelers, dark wizards, mad scientists, alien invaders and telepathic mutants. The kids steal weapons and resources from their parents and learn that they themselves inherited their parents' powers; Alex Wilder, a prodigy, leads the team while Nico Minoru learns she is a powerful witch, Karolina Dean discovers she is an alien, Gertrude Yorkes learns of her telepathic link to a dinosaur, Chase Stein steals his father's fistigons (fire gauntlets) and x-ray goggles, and young Molly Hayes learns she is a mutant with incredible strength. The kids band together and defeat their parents and atone for the sins of their parents by fighting the new threats trying to fill in the Pride's void. Later, they are joined by the cyborg Victor Mancha, the shape-shifting Skrull Xavin, and the plant-manipulator Klara Prast.
