Due to his super hero duties as of late, Max has been failing school. His teacher while rummaging through his bag in search of his science project one of his teachers stumbles upon Steel. Initially planning to get Steel back Max realizes that the accidental deception is his only hope of a passing grade, passing with flying colors when the teacher is led to believe it's a electronic shoe warmer. The next day Extroyer learns of the Ultra-Link on display at the school and buys it, inspired by their last encounter Extroyer has created a device to 'unleash all of his powers at once.' Max calls in N-Tek to help stage a rescue mission and faces off against a monstrous chimeric fusion of Extroyer with all of his animal forms. After narrowly retrieving Steel in time Max is able to force Extroyer to surrender, escaping at the last moment by setting the adapter to self destruct. Back at school Max decides to make a honest attempt at a science project, while not looking as impressive as Steel the teacher decides to pass Max any way.
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.
