While making their way across the Snowlands, Megan and her party come across the badly wounded King and Fighter. Akina takes the injured robots back to Dr. Coy's lab. At Just as Megan reaches the Zentrium stronghold, Giant-Robot and Silver-05 appear. Zeus goes into action, but the battles are fierce.

Despite a series of booby traps, Megan turns off the fourth Zentrium. However, Mango gets frozen solid when he heroically steps between Megan and a freeze gun. Meanwhile, OmicronPsy transforms Dark-General into a new robot that can take two Zentrium chips, independent of the Emperor's Zentrium. Dark-General is sent to the Sky-Stronghold to defend the fifth Zentrium.
