Being a superhero sidekick isn't as fun as you think. You do all the work, beat the bad guys and save the planet, only for your grown-up partner to get all the credit. Junior Justice is sick of it, so he and his sidekick pals, Flygirl, Dinomite and Goo, have decided to form their own super team.

But before they can start saving the world they'll have to prove to the adult heroes that they're more than just sidekicks. And once the evil Dr Enok discovers his favourite pet Goo has left him to join a super team, the world might need saving sooner rather than later!
