I am Dr. Gero, chief engineer of the Red Ribbon Army. I developed a hatred towards Goku for defeating the Red Ribbon Army. I devoted the rest of his life trying to destroy Goku by creating a number of androids to do the job, but was later killed by Android 16 while I was creating him. With the help of Android 19, Android 20 was born. Now I am a superior killing machine. I will now lead off my androids to kill Goku and used the Dragonballs for world domination!
