Cell saga

It is now 3 years after the arrival of the mysterious boy. He had told Goku that they were supposed to train for the arrival of two strong beings, cyborgs (Jinzou Ningen), created by Dr. Gero. They did as the mysterious boy told them, they trained hard for three years. They waited for the arrival of the two cyborgs in the place that they were said to be, and there they meet C-19 and C-20. C-19 is the last of a series of creations to destroy Goku. Along with the scheme, Dr. Gero requests C-19 to make him (Dr. Gero) into a cyborg so that he would become stronger, and so Dr. Gero is transformed to C-20. The Z Warriors meet with C-19 and C-20 and the two sides engage in battle. Goku leaves the battle because of his heart disease and leaves the battle to Vegeta. The cyborg is destroyed and Dr. Gero is shattered. Despite the grave defeat, Dr. Gero's cybernetic programming enables him to self-repair, so that he may live to fight again.C-20 then works on developing a better cyborg model. Meanwhile, he unleashes two of his other creations, C-17 and C-18. C-17 and C-18 get annoyed of Dr. Gero. As a result, C-17 kills Dr. Gero. C-17 and C-18 leave the lab and unleash C-16. But as it turns out, C-16 is a peaceful cyborg. (This can be shown through his love towards the wild animals.) As time passes, the Z Warriors become aware of the new cyborgs as they battle again and again but always reach a stalemate. However, the Z Warriors are still not match for the cyborgs because they are robots, and therefore do not tire in a long battle while the Z Warriors eventually run out of energy. Goku suffers a heart attack in one battle and retreats. Trunks, who was sent back in time by future Bulma with medicine to heal Goku's heart so that Goku would live to kill the cyborgs and thus change the future, gives Goku the medicine. Goku is saved, but the Saiya-Jins still do not continue to fight the cyborgs. Instead, they train in a chamber to get stronger. Meanwhile, Piccolo fuses with Kami-Sama, his half father, to become stronger (His story is told in the DragonBall series.) We then learn about Cell, a creation made by Dr. Gero’s computer, it’s not really a cyborg, because he’s made of Cells from all the Z warriors. In one of the futures, all created by the Time Travel machine, Trunks has stopped the cyborgs using the emergency stop device, so Cell, who needs the cyborgs to become perfect, can’t find them, so he kills Trunks and use the Time Travel Machine to come in our present. But he needs to make a reverse mutation to be able to enter the time travel machine, so when he arrives on earth, he needs to transform again, and it takes him many years, then, he devours the souls of the unlucky civilians he passes to become stronger. Dende, a Namek child, replaces Kami as guardian of the DragonBalls. C-16, C-17, and C-18 go to seek Goku to destroy him. Piccolo finds the androids first and begins to fight them. Cell is able to feel Piccolo’s Ki, so, he flies to find C-17 and C-18. Finally, he meets with them. To our heroes' surprise, they learn that C-17 and C-18 know nothing about Cell. Cell and C-17 threaten to kill each other. C-17 heads out to fight him. But, he does not stand up to Cell and is easily defeated. This is when our heroes learn the great powers of Cell. C-18 is now worried, but C-16 flies out to fight Cell. To everybody's amazement, C-16 is able to stand up to Cell. However, he is still destroyed. Cell now heads for his goal and devours C-17 with his tail. Cell now changes into Cell form 2. With the power of C-17 combined to his, he becomes stronger than ever. Then, Vegeta comes out of the time and spirit room, and fight Cell, but he thinks that Cell isn’t strong enough, so he lets him absorb C-18. Cell now changes into Cell form 3, and becomes "Perfect Cell", and he's now stronger than Vegeta so Cell beats him up a little. Then Trunks take his turn but he isn’t as strong as Cell. Cell leaves, and tell them about the Cell Game, a tournament he wants to organise to see if people can be stronger than him. After Cell is gone, Bulma collects the body parts of C-16 and repairs him. He is re-programmed to fight on the Z Warriors' side. Our heroes now head out to the Cell Game. Mr. Satan attempts to fight Cell, claiming to be the strongest man in the world, but does no damage to Cell. It is now Goku's turn to do battle with Cell. A battle that is so fast, that a regular person cannot see it with the naked eye. At first, the two just play around and give the other hopes, but later on, they fight for real and this proves to be a very hard battle. Goku does a Kame-Hame-Ha to Cell that blows away his head and arms, but Cell, with Piccolo's power is able to grow out a new one. After this things look bad for Goku, and so he gives up and tells his son, Gohan to fight instead. Gohan does as his father tells him, but is still not fighting with his maximum power. Cell tries to make Gohan angry so he can release his powers by expelling from his body 7 Cell Juniors, miniature blue duplicates of Cell. These Cell Juniors are beating up all of Goku's friends while he is just watching everything. C-16 tries to destory Cell by self destructing, but Bulma had taken away the bomb inside him and so Cell kills him. After he is dead his head is still able to talk. And so C-16 asks Mr. Satan to throw his head towards Gohan so he can talk to him and so he does (this is the only real thing that Mr. Satan does in this tournament). When C-16's head arrives at Gohan's feet, he talks to him and tells him that some people will never understand with words, and to let out all of his hidden powers. At this Cell walks towards Gohan and steps on C-16's head, which finally kills him. The death of C-16 triggers his anger, an enraged teenage Gohan powers up and reaches Super Saiya-Jin level 2. Gohan then destroys all the Cell Juniors and fights Cell easily, while not even Goku was able to keep up with them (The Cell Jrs.). In a following battle, Cell is kicked and C-18 is spit back out. (She is unconscious.) Cell turns back into form 2 and is defeated. But, he activates his self destruction mode so that when he dies, the world will blow up with him. To save the Earth, Goku teleports Cell out of Earth and on Kaioh-Sama's planet, where Cell blows up. Thus, Goku, Kaioh-Sama, Bubbles, and Gregory die as well. The Z Warriors mourn the loss of Goku, but cheer at the victory over Cell at the same time. A fireball flies out of nowhere and pierces through Trunks. Upon Trunks' death, Cell, in form 3, appears. He tells that when he blew up, a brain cell survived. From the cell, other cells multiplied and he was once again formed. Cell happily laughs as he tells that he is amazed he is able to rebuild himself into form 3! Then, Cell threatens to destroy the earth. Now it is up to Gohan to try to save our planet. With one arm (the other injured when he went to let a fireball meant for Vegeta hit him), Cell prepares a fireball. He fires and Gohan is not able to fire back. A stalemate is meant, but with Kaioh's help, Goku is able to talk to Gohan and encourages him. So Gohan finally fires back. Meanwhile, Kuririn protects the unconscious C-18 and Yamcha, Tein, and Vegeta attack Cell in hope that this will Gohan distract Cell. With the help of the now dead Kaioh, Goku, also dead, is able to communicate with Gohan and encourages him to use all his power to defeat Cell. Gohan overpowers Cell and Cell is disintegrated by Gohan's fireball. (But, Satan takes credit for Cell's death because of his lies to the reporters.) At the end, the warriors gather the dragonballs to bring those killed by Cell back to life. However, Goku is still dead because he was already brought back to life once and cannot come back again, but tells that he is okay and is now with Kaioh. C-18 awakens and flees. However, everybody learns here that Kuririn has developed a crush on C-18! At the end of this series, there is a short memorial about the life of Goku. And there is peace on Earth.
