Future Vegeta is the alternate timeline counterpart of Vegeta who appeared in the alternate timeline in which Future Trunks and Future Gohan lived. This version of Vegeta makes his only appearance in the brief opening scene of Dragon Ball Z: The History of Trunks, and in a flashback during an episode of Dragon Ball Z. Future Vegeta was the lover of Future Bulma, and the father of Future Trunks.
In Age 766, Future Goku had been stricken down by a deadly Heart Virus that had no cure. Future Vegeta, along with the other Z Fighters and company await the news of Future Goku's health. However, Future Goku passes away, leaving Future Vegeta shocked about Future Goku's death and finds himself very upset due to the fact that he will never get his chance to defeat his rival in battle. Six months later on May 10th, 767 Age, the Androids attack and Future Vegeta is killed by Future Android 17.
- It is debatable how Future Vegeta died as in the special he is shown being killed by a hard kick to the stomach by 17, but in the episode "Ghosts from Tomorrow" it is shown during a flashback that he dies after being struck by an energy wave while stuck in the ground. However, in both instances, he retains his Super Saiyan power and abilities.
- Future Vegeta was 35 years old when he died.
- Given that the main timeline version of Vegeta stayed on Earth to one day fight Goku and the androids, and seemed to hold little regard to his family initially, it is unclear why his future counterpart would remain on Earth in the years after Future Goku's death. It is possible that he (and his main timeline counterpart by extension) always did care for Bulma and Trunks deep down, regardless of how unwilling he was to admit it. It is also possible that he was either stranded or just generally directionless after Goku's death, but the reason is not explicitly stated.
- Goku died a mere 6 months before the androids arrived. Vegeta was there 2 and a half years while Goku was still alive.
- In hindsight, Future Vegeta's death at the hands of the Androids even as a Super Saiyan could be interpreted as a very strong foreshadowing of an important plot developments: that Future Gohan and Future Trunks (both who only attained the first Super Saiyan transformation) would fail miserably in their respective fights against the Future Androids, and never would have found the next super saiyan transformation.
