After the third Zentrium has been shut down, Megan and friends all celebrate. But soon they are preparing to go all out for their next objective: the Zentrium at the South Pole. Meanwhile Quantum and Webster go off looking for some fighting robots to fight. Not far from the location of the 4th Zentrium near the Sky Stronghold where Webster lives, they come under attack from Silver-04. Quantum and Webster have their hands full with Silver-04, and then Dark-05 joins in against Quantum! At this moment, Megan and Nick are hit by a snowstorm and get socked in on an ice floe at the South Pole. In the end, Quantum triumphs over his assailants but is seriously wounded in the process. In order to repay Quantum for his courage, Webster and the BirdMen urge Quantum to stay behind and rest his wounds. Quantum finally agrees.
