Heart virus

From Dragon Ball Wiki, the ''Dragon Ball'' encyclopedia

Goku passes away due to the Heart virus.

The heart virus is the deadly, incurable virus that Future Goku contracts in November or December of 766 Age, and unfortunately dies from in Future Trunks' alternate timeline. Six months following his death, the androids appear and murder all of the Z Fighters with the exception of Future Gohan, thus sparking the events of The History of Trunks as well as the Trunks, Androids, and Cell sagas.

[edit] Main timeline

In the main timeline, Future Trunks arrives from the future and gives Goku the antidote to the virus. However, his presence in the past causes history as he knows it to change drastically. One major change is that Goku does not contract the heart virus when he was originally supposed to, but instead it appears six months later during his fight with Android 19 in May of 767. Goku is saved from death by Vegeta and taken home to receive the antidote. A few days later, the virus is successfully cured, and Goku re-joins the fight against the androids and the new threat, Cell.
