Goku, the strongest Saiyan, is nearly defeated by a heart virus. How did he, who battles gods, get so vulnerable?
The Heart Virus attacks Goku’s heart. Senzu Beans can't cure it, leaving even Goku powerless against its grip.
In Trunks' future, Goku dies from the virus. But Trunks saves him in the main timeline with a crucial antidote.
Fans suggest Goku got the virus from Yardrat, Namek, Earth's forests, or Dr. Gero’s plan. Its origin is a mystery.
The virus resembles myocarditis, showing Goku's vulnerability. Trunks' antidote hints at future medical hope.
