Vomi

Vomi is the canonical identity of Android 21. She is introduced in Dragon Ball lore as the wife of the evil Red Ribbon Army scientist Dr. Gero, the mother of their son Gevo, and the grandmother of Dr. Hedo. Long before the Android Saga, Vomi was a brilliant researcher who worked for the Red Ribbon Army alongside her husband, Dr. Gero. Together, she and Gero had two sons. One of them, a Red Ribbon soldier named Gevo, was killed in the line of duty. This profound loss heavily impacted the family, driving Dr. Gero to model Android 16 after their deceased son. Vomi is the human template for the bio-engineered character Android 21, who first appeared in Dragon Ball FighterZ. While Vomi died long before the Android Saga, her DNA and likeness were later used by Dr. Gero to create Android 21.
