"So it's agreed--as part of your parole, you'll become principal of Cape High," Mastermental says.

"No, it's not agreed," Nico snaps. He takes a deep breath, forcing himself to calm down. "It is not agreed, because none of the super parents will want their children taught by a super villain. Ask them! I'm sure they're all listening right now--heck, I'm betting this little interview is on Super TV right this instant."

This is how it starts, for us, the super kids, the cape brats, the students of Cape High.
