Android 20, also known as Dr. Gero, appears as a playable fighter in Dragon Ball Z Budokai 1, 2, and 3, as well as the Budokai Tenkaichi trilogy. In these games, he is characterized by his unique energy-absorption mechanic, allowing him to drain opponents' ki during battle. His storyline typically follows his role as the creator of the Androids and his quest for revenge against Goku.
Within the progression of the
Dragon Ball Z Budokai and
Dragon Ball Z Budokai Tenkaichi franchises, this character's representation evolved alongside the shifting gameplay engines. Debuting in the 2.5D fighting game
Dragon Ball Z Budokai (2002), his moveset featured signature techniques such as the Photon Wave and Bionic Punisher. He returned in
Dragon Ball Z Budokai 2 (2003) and
Dragon Ball Z Budokai 3 (2004), with the latter's expanded roster and refined mechanics being preserved in the European exclusive
Dragon Ball Z Budokai 3 - Édition Collector (2005).
The transition to the 3D arena-fighting style of the
Dragon Ball Z Budokai Tenkaichi (2005) series altered his playstyle, emphasizing spatial maneuvering and aerial combat. In
Dragon Ball Z Budokai Tenkaichi 2 (2006) and
Dragon Ball Z Budokai Tenkaichi 3 (2007), his defensive capabilities were highlighted through specialized counter-moves and barrier techniques. Across these titles, his campaign appearances recreate key historical battles from the Android Saga, particularly his encounters with Yamcha, Piccolo, and Vegeta, serving as a pivotal boss and unlockable roster addition.
