In Dragon Ball Z, all Z fighters die in the future timeline of Trunks. This is the reason why the Saiyan prince decides to travel back in time to warn everyone about the impending arrival of Androids 17 and 18, created by the evil scientist Dr. Gero and the Red Ribbon Army.
In the future timeline of Dragon Ball, Goku dies from heart disease, preventing him from fighting against the androids.
While Vegeta, Piccolo, Tien Shinhan, Krillin, Master Roshi, Yamcha, and Chaoz fall in battle against the two androids, Gohan – the only survivor – faces a devastating defeat at the hands of these powerful foes.
Eventually, Trunks travels back in time using the time machine built by his mother, Bulma, to warn the Z fighters about the events that transpired in the future.
However, there is an event that many people overlook. The existence of Cell in the current timeline is a direct result of this biological android, who, in his initial form, absorbed Trunks’ time machine to travel back to the past and potentially confront Androids 17 and 18, given that he achieved his perfect form.
This situation suggests that even Trunks himself dies in the future timeline, leaving only one survivor from the original timeline: Bulma.
It’s no coincidence that the most important person in Dragon Ball is the only survivor.
Those who admire the series often highly value the role that Bulma plays in Goku’s journey. If it weren’t for Bulma, there would be no Dragon Radar, no spaceship to travel to Planet Namek, and no time machine required for Goku and Vegeta to achieve their Super Saiyan transformations.
There is a future timeline where, despite any changes, Bulma remains the only survivor. We understand this fact more profoundly when considering her character, but she is indeed a rare asset in a universe filled with powerful and formidable beings.
