Dragon Ball Z - Season 7 (2000)

Attacked from within by a crippling virus, Goku is helpless against the maniacal Android 19. But just when it looks like the end for Goku, Vegeta appears on the scene! And he's got a few big surprises in store for the Androids!

In his first fight as a Super Saiyan, Vegeta takes control of the battlefield and defeats Android 19 in convincing fashion! Unwilling to share 19's fate, Android 20 runs for cover in the mountains!

Vegeta, Piccolo, and Gohan lead an exhaustive search through the mountains for Android 20. But the hunters are also the hunted! Android 20 lurks in the shadows, ready to strike, and it looks like Piccolo is his first target!

Our heroes make a startling discovery: Android 20 is none other than Dr. Gero himself! Before they can act on this new knowledge, the diabolical doctor flees to his secret laboratory, where he intends to awaken more killer androids!

The race is on, as the Z-Fighters search frantically for Dr. Gero's hidden laboratory. But rather than stop the Androids before they're activated, Vegeta wants a challenge. Despite Trunks' warning, he's chooses to fight the Androids alone.

Dr. Gero escapes to his mountain hideout and brings his killer androids to life. Without the help of Goku, all hope seems lost. Dr. Gero appears one step closer to ultimate vengeance, but his evil creations have a vendetta of their own!

Vegeta takes on Android 18, but finds himself seriously outmatched.

The Z-Fighters are totally decimated by the androids.

Vegeta, Trunks, Tien, and Piccolo realize a grim truth: unless they can increase their powers quickly, they'll have no chance against the androids. In a drastic move, Piccolo flies to Kami's Lookout and makes a most unexpected proposal!

The androids hit the road in pursuit of Goku, but they're delayed by some hyperactive hoodlums. Krillin and Trunks race to move Goku to a safer hiding place, and Kami wrestles with Piccolo's difficult offer.

Trunks must face the fact that he cannot change history and save his timeline.
