Dr. Gero finally makes it to his laboratory, with Krillin in hot pursuit. Tien, Piccolo, Vegeta and Trunks soon locate him and break into the lab, although Doctor Gero has already awakened Androids #17 and #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. In an act of desperation, Trunks launches a large ki blast 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.
