Cell

The Beginning

Cell is the ultimate creation of a scientist named Dr. Gero. Cell was cloned from several genes from the Z fighters of Earth, along with some from Nappa and Freeza. Since Cell possessed traits from other DBZ characters, he was called "perfect warrior". In his time, Android's 17 and 18 had been destroyed and he could not achieve his goal - perfection. He took Trunks' time machine and went to a time where the androids still existed.

Cell's existence is first hinted at when Future Trunks, Son Gohan and Bulma discover Cell's shed skin in a forest near a time machine. Cell is first seen when confronted by Piccolo, Who soon then learns his history of time travel, as well his plans to absorb Androids 17 and 18 to make his power more stable.

Semi-Perfect Form

Cell starts to absorb humans to get even stronger and finds the Androids. Cell easily brushes off Piccolo but is evenly matched with Android 16. But Cell manages to absorb Android 17 and become Semi-Perfect. In this form, he confronts Android 16 and badly damages him. Cell would then go after #18 before being stopped by Tenshinhan's Shin Kikoho. The android then fights the newly turned Super Saiyan Vegeta. He calls himself Super Vegeta. Vegeta easily beats Cell.

Perfect Form

After realizing that he could not beat Vegeta in this form, Cell uses Vegeta's Saiyan pride to trick him into letting him absorb Android 18 so that he would provide Vegeta with a more worthy challenge.

But little did Vegeta know that Cell's new form was more that what Vegeta's Ascended Super Saiyan form could handle. After he absorbed #18, he fought Vegeta again proving his theory on his Perfect Form. Vegeta was no match for Cell, forcing Future Trunks to step in to save his father.

Trunks turned to Ascended Super like Vegeta but powered up even more to Ascended Saiyan level two much stronger than Vegeta . Like the Super Saiyan form his father used, he became stonger but unlike him he became bulkier and slower. Which resulted in him being stronger than Cell but too slow to keep up so he loses the fight. Cell, disappointed at the Saiyans' display of power tells Trunks about a tournament that he will host to test his new found power called the Cell Games. He allows Trunks to live and tell the other Z warriors about this tournament and allows ten days for them to prepare. Cell makes this announcement to the world via news station so the strongest fighters in the world can come challenge him, and meet him in the ring that he created.

Cell Games

During the Cell games, Cell and Goku fight the first match and Goku, in the end, surrenders to Cell and tells him that he couldn't win. He tells Gohan to fight Cell, but Gohan is shocked to hear this. Later in the Cell Games, Gohan fails to defeat Cell and the android goes after the others by producing Cell Jr's. After Cell destroys Android 16 and crushes his head, this unlocks Gohan true power within, fueled with rage and Gohan turns into Super Saiyan 2. Gohan kills all the Cell Jr's with ease and fights Cell after. At first, Cell thinks it wouldn't make any difference, but soon realizes that he is fighting a losing battle and gets serious, but goes to no avail. Cell turns uses his power-weighted form to fight Gohan, but this lowers Cell's speed, a crucial mistake. Gohan easily defeats Cell in this form and Cell regurgitates out Android 18, turning him back into his second form. Cell then turns to drastic measures.

Death of Goku

After Cell loses his perfect form, he turns to self-destructing himself to take the Earth and the Z-warriors with him. No one attacks Cell because if they did, Cell would self-destruct. Goku goes to Gohan and tells him to take care of Chi-Chi for him and goes to Cell. He places a hand on Cell and teleports to Kaio-Sama's world unexpectedly and Cell is enrages by this. Cell then self-destructs and destroys the small world and taking everyone there with him, including Goku.

Cell's Resurrection

After the self-destruction, a small part of Cell survives and regenerates into Cell again, but this time Cell is back to his Perfect Form and he has achieved his Super Perfect Form, making him stronger than before. He teleports back to Earth to fight the Z-warriors once again, especially Gohan.

The Final Battle

Cell arrives back to fight Gohan and shortly after, he shoots through Trunks with a beam, enraging Vegeta and attacks Cell, but is overwhelmed by Cell. Cell is about to hit Vegeta on the ground with a chi blast when Gohan saves Vegeta by using his own body to block the attack. It damages Gohan's arm and leaves him with one arm to use. Cell gets ready to destroy the Earth by charging up a kamehameha, which he claims is strong enough to destroy the entire solar system, and fires it at Gohan. Gohan uses a Kamehameha blast with his one arm and gets into a beam struggle. Cell starts to overpower Gohan when just before Gohan was about to give Goku talks to Gohan through Kaio-Sama and tells Gohan to let his power explode and not give up. Cell gets ready to overpower Gohan when suddenly he gets hit by a small chi blast from Vegeta and gets distracted. Goku tell Gohan to use his full power and Gohan unleashes it to the Kamehameha beam struggle. Cell is caught off guard and is completely overwhelmed, obliterating him to oblivion, thus ending his existence on Earth.
