Welcome to Gladstone's School for World Conquerors, a top secret academy for the children of the world's greatest super villains to learn the trade. Join us as Kid Nefarious, Mummy Girl, Martian Jones, Ghost Girl, and the infamous Skull brothers unearth the School's and their parent's hidden past.

School's back in session at Gladstone's School for World Conquerors, but everyone's favorite supervillains-in-training have more to worry about than making the dishonor role. Eager to avenge their parents, Kid Nefarious, Mummy Girl, Martian Jones, Ghost Girl and the Skull Brothers took out the Red Stormbreaker...only to learn that he was the only one who could stop Shiran, a cosmic destroyer who's set to eat the sun in just a few weeks. Will they be able to make it out in one piece, or will the Skull Brothers kick the hornet's nest with them in it?

Kid Nefarious, Mummy Girl, Martian Jones, Ghost Girl, the Skull Brothers, Man-o-War, and The Speed Spectre are on a Cosmic Quest to gather the armor that will allow them to defeat Shiran, aka the "Storm of Death," who's set to devour the sun in just a few weeks. But before the "Maleficent Seven" can stride into the eye of the storm, they'll have to take on the vile Scorpio Kane and his gang of muscle-and-menace for hire, all while hoping their parents won't figure out that they're not actually on a field trip. It's their biggest battle yet. Can Kid Nefarious and company prevail, or is it lights out for them...and everyone?
