description: With the defeat of the Triple Triad and the aftermath of their attack on Valcav, it's time for Nick and his classmates to start a new semester on Inferno Island with a show of solidarity and peace: a parade.  But when a long-lost hero comes back with his army of robotic penguins to kill Nick’s father, any hope for peace is thrown on its head. If that wasn't all, Carter Academy and its villainous students are about to unleash a diabolical plan unlike any the world has ever seen.  And if Nick wants to save the world, his friends, and his family, he’ll have to find a way to power up unlike ever before, fight his way through not one but two secret bases, and defeat the most powerful hero on the face of the planet.
