Max and Steel decide they need the Turbo Star to defend Earth from Makino, who is now back with his armada and on his way to Earth. And when Dredd offers him the pieces if he can come up with the third piece, Max must first locate the missing piece and then decide if Dredd can be trusted.
16 year old Maxwell "Max" McGrath is thrown into a new life after moving with his mother to the small city of Copper Canyon. There he meets new friends, bullies, and super-villains hunting him for his TURBO energy.
Max must now join N-TECH, a secret organization his late father Jim McGrath started, to defeat Trans-Human Industries from taking over the galaxy with their sinister leader Miles Dredd. Max's powers are hidden and regulated with the aid of his Ultra-Link friend Steel, who is a project of his father, to prevent Max from going critical and Steel transforms into Max's multiple armors for whatever terrain battle is present.
Along the way, with the aid of N-TEK led by Max's uncle Ferrus, both will uncover the mystery behind many of Steel's lost memories and what really happened to Max's dad.
