Future Tien

Future Tien is the alternate timeline counterpart of Tien. He is seen briefly in Dragon Ball Z: The History of Trunks and in the Dragon Ball Z episode "Ghosts from Tomorrow" during a flashback.

Background
Future Tien's life was exactly the same as his main timeline counterpart's life until the Trunks Saga. In August of Age 764, Tien watches as Future Son Goku uses the Instant Transmission to arrive on Earth and kills Future Frieza and Future King Cold (something Future Trunks' arrival in the main timeline alters). Two years later, in Age 766, Goku dies from a lethal Heart Virus, and is unable to be wished back due to the death being of natural cause. Tien is shown outside Goku's house when Goku dies.

On May 12 Age 767, two killer androids appear. Coming to the defense of Earth's inhabitants, Future Tien and the other Z Fighters engage the androids in battle. In the TV special prologue, Future Tien is shown in receiving a swift punch to the stomach by Future Android 18, and in Future Trunks' flashback in "Ghosts from Tomorrow", it is shown that 18 killed him by blasting a hole through his chest with her High-Pressure Energy Wave. Future Tien is the fourth Z Fighter killed by the androids; he dies after Future Yamcha and before Future Kuririn. The only survivor of the battle is Future Gohan, who dedicates his life to avenging his fallen friends. Future Tien was 34 years old when he was killed by the androids.
