Three years have come and gone, and the day of reckoning has finally arrived! The Androids are here, just as Trunks predicted, and they're wreaking havoc on an unsuspecting city! Goku and his friends must now put their training to the test, but are they ready to face these mechanical monsters?

Yamcha is held at the mercy of the ruthless Android 20, and Goku and the others must race to help their friend. Believing their power to be far superior, the Androids tempt Gokua 's rage by leveling half of the city! But therea 's one thing the Androids didna 't count on -- Gokua 's a Super Saiyan!

The battle with the Androids begins in earnest as Goku launches an all out assault against Android 19. The Super Saiyan seems to have the fight well under control, but something is horribly wrong! Gokua 's strength is mysteriously draining away! And Android 19 isna 't showing any signs of slowing down!

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 hea '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 19a 's fate, Android 20 runs for cover in the mountains! Now Vegeta and the rest of the Z-Fighters must find the diabolical Android and put a stop to his evil ways. The hunt is on!

Vegeta, Piccolo, and Gohan lead an exhaustive search through the mountains for the wily Android 20. But all is not as it seems -- the hunters are also the hunted! Android 20 lurks in the shadows, ready to strike, and it looks like Piccolo is his first target! Can the mighty Namek withstand the Androida 's energy-draining attack?

Our heroes make a startling discovery a " Android 20 is none other than the evil Dr. Gero himself! But this new revelation may have come too late, for the diabolical doctor has fled to his secret laboratory, where he intends to awaken two more killer androids! Can the Z-Fighters stop him in time?

The race is on, as the Z-Fighters engage in a frantic search for Dr. Geroa 's hidden laboratory! But rather than stop the androids before they're activated, Vegeta wants a challenge! And against Trunksa ' sage advice, hea 's bent on fighting the androids alone! Can Trunks dissuade Vegetaa 's suicidal course of action?

The demented Dr. Gero escapes to his mountain hideout and brings his killer androids to life. Without the help of Goku, who’s bedridden with a deadly disease, all hope seems lost. It looks like Dr. Gero will finally get his revenge against Goku. But wait! His evil creations have a vendetta of their own!

Vegeta faces off with Android 18 for a showdown on the highway. Even though Trunks and the others are there to help, the Saiyan prince insists on battling his opponent single-handedly! Will Vegetaa 's overconfidence against this android of unlimited power be his undoing?

In an earthshaking battle, the beautiful Android 18 brings Vegeta to his knees. But before she can deliver the final blow, Trunks steps in to help. Soon an all out war between good and evil begins, with the androids gaining the upper hand. Now the unhindered androids set their sights on the ultimate prize - Goku!

Struggling to recover from their fight with the androids, Vegeta, Trunks, Tien and Piccolo realize a grim truth: unless they can increase their powers quickly, they have no chance against the android trio. In a drastic move, Piccolo flies to Kamia 's place high above the earth and makes a most unexpected proposal...

The evil androids hit the road in hot pursuit of Goku but are delayed by some hyperactive hoodlums. Krillin and Trunks race to move Goku to a safer hiding place, while up in the clouds Kami wrestles with Piccoloa 's difficult offer. Everyone is scheming of ways to stop the androids, but will any of them work?

With the androids close behind, the Z-fighters retreat to Master Roshi’s house to plan their next move. And with Goku still in poor health, their list of options is short. Bulma makes a disquieting discovery - the wreckage of a second time capsule! Where did it come from, and more importantly, who was in it?
