Dragon Ball Z : Season 4

Dr. Gero believes that Androids 17 and 18 will be the keys to his victory, but problems arise. For one, his run-in with Krillin just leads the other Z Fighters right to him. However, by the time they arrive, Dr. Gero is in his laboratory and activating the two Androids. He orders them to destroy the Z Fighters, but 17 and 18 display a lack of obedience. They quickly turn on their creator. Meanwhile, Yamcha and Chi-Chi watch over a struggling Goku. He looks bad, but what he's dreaming is even

Lots of surprising things await the Z Fighters at Dr. Gero's laboratory. For one, Android 17 finishes Dr. Gero. Also, Android 18 finds a pod containing the dormant Android 16. Trunks unleashes a powerful energy blast in an attempt to destroy them all, but to no real effect. Once 16 is activated, he reveals his mission is to kill Goku. 17 and 18 decide that would be fun and take 16 to find Goku – ignoring the Z Fighters in the process. Vegeta, though, hates being ignored and pursues to get a

Android 18 accepts Vegeta's challenge for a fight. Krillin, Piccolo, Tien and Trunks soon arrive to the battlefield. Vegeta doesn't want their help and Android 17 promises to stay out of the fight if they do. He also notes that Vegeta is very strong, but doubts by enough. He is soon not alone in thinking that. Piccolo notices that Vegeta grows weaker, while 18 doesn't. The results speak for themselves, as Vegeta soon takes a beating. Trunks races into action to save his father – triggering an

Trunks has leapt into battle, and has been joined by Piccolo and Tien. Krillin, however, is too afraid to do anything but watch. Though Android 18 doesn't need the help, Android 17 is no longer bound by his earlier promise and also enters the fray. Their combined might easily crushes the Z Fighters. They don't kill them, though, and soon leave with Android 16. With the sick Goku their target, what can possibly be done now?

The Z Fighters' sole good news right now is that they are still alive. Vegeta storms off to train harder and vent about his humiliating defeat. Piccolo also leaves, but is not forthcoming about why. Krillin, however, figures it out – he is going to ask Kami to reunite into one, powerful being. Kami is not surprised by this development, but he needs time to think about it. Tien decides to head off on his own, while Krillin and Trunks race to reach Goku's house. They have to get him and the

Kami has much to consider. He and Piccolo reuniting could possibly save the world, but the latter's past doesn't prevent frightening possibilities from being overlooked. Meanwhile, Goku is barely stable now and needs time to recover. Unfortunately, the three Androids aren't willing to give him the time. The Z Fighters evacuate him and Chi-Chi, and they fly to Master Roshi's island. Also, thugs learn what the Z Fighters already knew – Androids 16, 17 and 18 should never be provoked.

The three Androids are on their way to Goku's house – unaware that no one is there to greet them. Meanwhile, during the flight to Master Roshi's island, Goku has horrific nightmares – nightmares that are all-too close to reality. Also, Trunks and others discuss his future, his time traveling and the constant changes. The answers create some headaches and things Trunks never considered. However, while flying by, something unusual is found on the ground below. An investigation reveals that it
