Android 19

Intro Android 19 is Dr. Gero's nineteenth creation, designed to serve Gero's vendetta against Goku, who overthrew the Red Ribbon Army as a child. Out of all of Dr. Gero's Androids, 19 is by far Dr. Gero's most loyal and obedient creation. He is committed to Dr. Gero's quest for revenge against Goku and was very eager to face Goku himself. He is also apparently very intelligent as he was able to convert his creator Dr. Gero into Android 20, an energy absorption model like himself. He is quite confident in his abilities and appears to take pleasure in his opponent's suffering such as when Goku was weakened by his Heart Virus. However he relies too much on the data gathered by Dr. Gero's Remote Tracking Device which only follows Goku and the Z Fighters' battles of the Vegeta Saga and Trunks Saga, leaving 19 overconfident after defeating Super Saiyan Goku who 19 was only able to defeat due to the Heart Virus and unprepared when facing Super Saiyan Vegeta who had been training.
