The concept of a high school for budding superheroes is a common theme... but here is a place for all the would-be supervillains to get their start!
There's an outline of the Academy, buried in a bunker deep below an ordinary and quite innocent high school, with notes on some of the teachers and students. The students are graced with full write-ups and stat blocks, the teachers merely get an outline of their (decidedly crazy) personalities and teaching style. The supervillain community, not usually noted for its generosity, has funded the Academy generously.
Several adventure seeds are also provided. Two are aimed at regular superheroes, one in particular at those attending a high school for young 'heroes; whilst two more are intended for supervillain-focused games. One of these involves students at the Academy, the other puts the party as supervillains invited to an open day.
It's a neat idea, and one which could develop into an interesting part of your campaign.
