Aired on March 25, 1992

Bulma arrives to find that Android 20 is actually Dr. Gero. The scientist uses an energy blast as a smokescreen to flee and activate Androids 17 and 18, which knocks Bulma away. Trunks saves his mother and his younger self before following Vegeta to prevent him from confronting the Androids directly. Meanwhile, the group attempts to locate Gero's laboratory before he does. The narrative focuses on whether they can reach the facility in time to stop the scientist's plans. The outcome of this race against time remains uncertain as the characters split up to address the immediate threats and the larger conspiracy involving the newly activated androids.
