Mike Miller, a sniper released after 35 years, receives a freeze tank from Galactor to eliminate the Science Ninja Team. After satellites near the south pole are destroyed, the team investigates. Joe and Ken pursue a tank, but Joe is frozen in the G2 car. Ryu attempts to save Jinpei but freezes the G-5 as well. Mike hesitates to shoot Jun, missing because he sees his long-lost daughter, and his weapon overheats. The G1 ignites the tank, killing Mike. He reveals he took bullet cores to prove his comrades are alive and explains his hesitation. Ken reflects on their non-lethal approach aboard the God Phoenix.
