The Comet Squad is finally starting to click: Kid Comet and Pink Pulsar out front, Mikey as the man behind the keyboard. But the cracks that formed on their last adventure are starting to open up, and their biggest enemy, the evil genius Mastermind, is still out there somewhere. Just when the team feels like it might fall apart for good, students at Ronald Reagan Middle School start developing superpowers. All signs point to Mastermind's dangerous superpower pills. Now, the Squad must face their toughest mission yet: fixing their friendship and stopping Mastermind... before his new "superkids" spin totally out of control.
