Android Number 16 - “Jinzouningen Juuroku Gou”
Android Number 17 - “Jinzouningen Juunana Gou”
An enhanced human, Number 17 is technically a cyborg, rather than an android. Both he and his sister, Number 18, were once gang members who were captured by Dr. Gero and forced to undergo the mad scientist’s numerous experiments, in which he wiped their past memories of everything, including their names, and gave them great power by combining machine and man, creating two magnificently powerful cyborgs. Number 17’s last real battle in Dragonball Z takes place with Piccolo, a fight that ends in a draw (though it can be argued that the fight was never finished). The android is later absorbed by Cell and dies with him, but he is resurrected with the dragonballs. He lives alone in the forest for the remainder of Dragonball Z, until later in GT, when he returns to fuse with his clone (which Dr. Gero and Dr. Myuu built in Hell) and become Super 17, a being so powerful that he gives even Super Saiyan 4 Goku a run for his money.
Android Number 18 - “Jinzouningen Juuhachi Gou”
Though referred to as androids, both she and her brother Number 17 are humans enhanced by machines, or cyborgs. A bit calmer and more thoughtful than her brother, Number 18 takes a much larger role in the series. She marries Krillin later in Dragonball Z, and their daughter is named Marron (not to be confused with Maron, Krillin’s ex girlfriend from the Garlic Jr. Saga). Number 18 goes on to fight alongside Goku in GT and some of the movies as well.
Android Number 19 - “Jinzouningen Juukyu Gou”
Unlike 17 and 18, Number 19 is a true android, with no human parts to him, although he is man-like in appearance. He has a white face and a strange yellow hat with one sharp point on the top. He is somewhat chubby, and in the dub version, his voice is quite high-pitched to the point of annoyance. Number 19 has the ability to absorb another’s energy by sucking it into each red ball on his palms whenever a ki blast is fired at him, thus making him stronger and weakening the opponent in one move. He nearly kills Goku, who is weakened by his heart disease, until Vegeta steps in, saving Goku on the claim that only he has the right to kill Kakarotto. Android 19 tries to absorb all of Vegeta’s ki by grabbing his wrists and refusing to let go. Vegeta takes care of this by ripping off his hands, then finishes him off with his new lethal move, the Big Bang Attack.
Android Number 20 - “Jinzouningen Nijuu Gou” (Dr. Gero)
This android shell serves as a new body for Dr. Gero in order for him to carry on his life. After finishing Androids 17 and 18, the doctor created a robotic version of himself, which he calls Number 20, removed his brain from his own frail, aging human body and placed it in the powerful, immortal body of an android. Like 19 he can also absorb energy in through his palms, and is eventually killed by his own creation, Android 17, who kicks Dr. Gero’s head off and stomps on it.
