When you,vegeta,trunks,krillin and piccolo and turn found doctor Gero's lab which was deep in the mountains. Trunks used a ki blast to blast the door open when you guys entered doctor Gero Activated Android 17 and Android 18 but when you guys broke into his lab Android 17 steals the remote from him. Much to Gero's horror, Android 17 then crushes the remote and tells Gero that he will not put them to sleep again. Gero yells at Android 18 not to activate Android 16, but Android 17 punches Gero through the chest from behind. While Gero is confused, he pulls his hand out and decapitates Gero with a kick. He calls Android 17 and Android 18 pieces of junk. Android 17 runs over near the door and destroys Gero's head as you guys watched.
Android 16 was now activated and Android 17 asked if he was built to kill Goku and Android 16 responds with a monotone voice. "Yes." Android 17 says that he hates following Gero's programming, but that as machines they need a sense of purpose. The trio then rises into the air and flies away. But They all stopped at the mountain side of the road Android 18 sees you guys and asked Android 18 to handle vegeta but he refused saying his only purpose was to kill Goku so Android 18 sighed and she said she'll deal with one of you.......she picked you.
Android 18 had unlimited energy since she was an android you than managed to hit her into a rock and fire a ki blast at her when the smoke clears, Android 18 is still standing. She is damaged and her clothes are torn. Android 18 removes off her jacket, smiles with a quite surprise expression and gently pushes a some strands of her blond hair behind her ear
"Wow actually, wow I can't believe a human is able to somewhat hold there own against me even if I'm holding back" Android 18 smiled slightly in amusement
