Comic Book: Necessary Evil

Jacob and Miller had an ordinary life. At least they did before they found out that their mother was the Matriarch, the world's greatest supervillain, on the night of her death. They swore revenge on Ideal-Man, their mother's foe and killer. To achieve this goal, the brothers have enrolled in Necessary Evil, the school for supervillains and their mother's alma mater.
