When Tanker Station 22 is attacked by the Fire villains, the workers send a message to Hero Factory. Concurrently, new heroes Nex and Evo are being presented by Mr. Makuro, who cautions that the upgrade process used to make the two Heroes is not ready to apply to existing Heroes yet. Alpha 1 arrive at the station and begin to fight with the attackers. Furno is ordered to go on reconnaissance, and discovers that the villains are drawing power from the fuel. Breez manages to save the workers by transporting them via Drop Ship while Fire Lord is distracted by Stormer and Furno. Stormer orders the team to retreat, but they are blocked off from the Hero Craft by the villains. Surge breaks away from the others and the villains chase after him. Back at the Hero Factory, Alpha 1 convince Makuro to upgrade them, and head back to the refueling station. During the fight, Furno requests back up from Zib, who sends Nex and Evo. Nitroblast and Drilldozer are subdued, but Fire Lord flees to absorb more fuel. As the Heroes close in, a ship ejects Jetbug and knocks Fire Lord away. Stormer apprehends Fire Lord, and Surge jumps out of the ship, telling the others how he took control of the ship. When they return to Hero Factory, Surge is upgraded and commended for his actions.
