Dr. Gero finally makes it to his laboratory, with Krillin in hot pursuit. Tien Shinhan, Piccolo, Vegeta, and Trunks soon locate him and break into the lab, although, by this point, Dr. Gero has already awakened Android 17 and Android 18. Although initially appearing loyal, the duo demonstrate their independence when Android 17 destroys Gero's remote, ensuring that he cannot deactivate them should they disobey him, and Android 18 attempts to activate Android 16, a fully mechanical model deemed a failure by Dr. Gero. Android 17 then kills Dr. Gero, by severing and then crushing his head. In an act of desperation, Trunks launches a Buster Cannon at the androids, hoping to destroy Android 16 before he is activated. Although the entire lab is decimated, both Androids and 16's pod remain intact, and he is awakened anyway. The trio then decide to carry out their initial orders, and set out to kill Goku. However, their plans are disrupted when Vegeta intervenes, challenging the three androids to a battle. After Android 16 refuses to fight, Android 18 steps up to face Vegeta.
