One evil follows right after in the form of Cell, a completelyorganic android made of cells collected  from Goku, Vejita, Piccolo, and Freeza. With his tail, he can absorb the power of his enemies, and by absorbing Androids #17 and #18, he transforms into his "perfect" form, becoming incredibly strong. Like Goku, he enjoys a good fight, and puts on a "Cell Game," a martial arts tournament in which the outcome will determine Earth's fate. The Z soldiers swiftly fall to him, and unexpectedly, it is Gohan's turn to prove himself, and he shows that his power exceeds even his father's levels! Tragically though, he is too late to save Goku, who sacrifices himself yet again to protect the world. Seven years pass before another evil awakes. Gohan, Goten, and Trunks - Vejita and Bulma's son - go to school and continue their training. However, it isn't long before they learn of Babidi and Dabura, creatures who plot to revive a being called Buu and destroy all life just for fun. Before they can though, they need a large amount of energy, which they take from people, who then turn into their zombies. Vejita, still obssessed with being the strongest fighter, willingly becomes Babidi's zombie; in exchange for his considerable energy, Vejita now has the power to defeat even Goku and Babidi is finally able to revive Buu. As Buu goes on a destructive rampage, Vejita realizes too late his mistake and tries to atone by a suicidal act. However, even this sacrifice does not stop Buu, and in his anger, Goku reaches Super Saiyan 3 level! Meanwhile, Buu purifies himself and splits into two entities - one completely evil, and one completely good. Unfortunately, the evil Buu devours the good one and becomes even more powerful than before. Drastic measures are called for in this ultimate fight, and the DBZ warriors learn of a legendary "fusion" technique that may be their only salvation. Goten and Trunks fuse to become the arrogant Gotenks, while Goku and Vejita fuse to become the invincible Vejito! However, only with the cooperation of everyone on Earth can the DBZ team defeat Buu once and for all. Dragonball GT, the final series, begins 10 years after the end of the Buu saga. Gohan is married and has a daughter, Pan. Vejita has settled down and also has daughter, Bra. Goku is accidentally wished to become a child again, and the adventure begins again! He learns of the Black Star Dragonballs, which are scattered throughout space, and resolves to find these dragonballs to become an adult again. However, he only has one year to gather the Dragonballs or the Earth will explode! Goku, Trunks, and Pan blast off into space to search for the balls, crash-landing on various planets along the way and picking up new friends and battling new enemies. They run into Baby, the only surviving member of Planet Plant, which was totally annihilated by the Saiyans long ago. He seeks revenge on all Saiyans, innocent or guilty, and possesses the ability to take over his victims' bodies and acquire their power. While Goku and his friends return to Earth with all seven Black Star Dragonballs, Baby also lands on Earth and takes over the bodies of Trunks, Gohan, and Goten. After leaving his victims' bodies, he also leaves behind in their brains an egg which turns his victims into zombies. When he finally finds a suitable body - Vejita's - Vejita-Baby is formed and in a short time, nearly all life on Earth is under Baby's control. He uses the Black Star Dragonballs to create another Planet Plant. Vejita-Baby seems indestructible - not even the reformed Buu or Goku can stop him! Goku transforms into his uncontrollable giant-ape form to try to beat Vejita-Baby, and actually reaches an unheard-of Super Goku 4 power level! Meanwhile, a cure for Baby's control is found and people on Earth are released from his power. However, the Earth is on the verge of exploding; the DBZ team transports everyone to Namek. There they use the Namek Dragonballs to wish for Earth's restoration.            In the final adventure, the dragonballs are gathered once again and the dragon Shenlong is summoned. However, the DBZ warriors are in for a shock - Shenlong has become evil due to negative energy that was stored inside the balls when evil wishes were made. The evil Shenlong transforms into seven dragons, each representing a different dragonball, and disperse. Each dragon has its own element, and the DBZ fighters separate to find the dragons and revert them to their true forms: the dragonballs. But things are never that simple; Ii Shenlong, the dragon of the one-star dragonball, absorbs all of the reverted dragonballs and surpasses Super Goku 4! Goku counters by fusing with Super Vejita 4 to become Super Gojita 4, but the union is too unstable to be useful for long periods of time. In a desperate attempt, Goku collects energy from all over the universe to create a fireball great enough to destroy the evil dragon. He succeeds for a last time, and in the end, disappears with the good Shenlong into the sky. Over ten years of Dragonball came to an end in November 1997, but it's popularity has not faded at all. Audiences worldwide have spent over a decade with Goku and his friends, thrilling at his incredible adventures and laughing at his mishaps. An exciting mixture of dynamic characters, blistering battle scenes, and complex storylines has transformed Akira Toriyama's hit into a virtual icon of Japanese animation, recognizable throughout its staggering international fan base.
