Cell dubbed The Perfect Warrior is an Android of great power who possesses all the cells of the greatest fighters of all time
Cell is a creation of Dr. Gero and is composed of the DNA of several of the Z fighters and villains from the series. As a result of this creation, Cell is able to use moves that the Z fighters can use such as the Kamehameha. When he was born, he found that in order to be completed, he would have to absorb Androids 17 and 18. Since when he awoke both were dead, he killed Future Trunks and used his time machine to travel back to when both Androids were still alive and began his conquest to achieve his perfect form.
Cell was created by Akira Toriyama, the original mangaka and writer for Dragon Ball Z. It is said that Toriyama had to go through several designs before he was satisfied with the way Cell looked in all of his forms.
Cell announces that his martial arts tournament The Cell Games will be held on live television. Soon afterwards The Z Fighters arrive in their most powerful forms (With the exception of Gohan who was in his Mastered Super Saiyan form as well as Vegeta and Trunks who were not in their Super Saiyan forms). As they arrive Goku announces that he will face Cell first much to Cell's confusion as he "wanted to save the best for last" however nonetheless Goku says he will still fight Cell first but immediately after this is said Mr. Satan (Hercule) arrives with his students Caroni and Piroshki to face Cell. Caroni first attempts to attack Cell from above however Cell quickly sent him higher with an enormous energy attack. Caroni proceeds to fall on the ground and immediately concedes realizing that Cell is in fact tremendously powerful, Piroshki then makes the mistake of rushing towards Cell head-first but he is easily flicked backwards by Cell's aura which overwhelmed Piroshki. Both fighters realize they are no match for Cell and attempt to warn Mr. Satan not to fight him however Mr. Satan quickly confronts Cell and launches a slew of quick punches and kicks that do not even faze Cell who proceeds to flick Mr. Satan into the mountains and after he himself realized he is no match for Cell he fakes to have intense stomach pains in order to avoid fighting Cell, he then proceeds to claim that the techniques displayed in the battle against Cell and The Z Fighters are simple "tricks" or better yet and more specific "illusions".
Goku in his Full Powered Mastered Super Saiyan form engages Cell in an intense battle where he seems to be able to be able to keep up with Cell as the two trade blows and unleash explosive energy in a climatic battle. Much to Goku's surprise Cell used familiar techniques such as the Kamehameha Wave and the Death Beam, as the fight continued Cell eventually became bored of being confined to a tiny ring and proceeded to destroy it turning his fight with Goku into an all-out and complete battle with no rules applied just to make things more interesting for him. As the fight progressed Goku used all of his power and effort going so far as to fly to the sky and begin powering up a very powerful Kamehameha targeted at Cell who was standing on the ground and Cell was noticeably afraid as he claimed that if Goku fired the blast he would destroy the Earth, The Z Fighters also began to fear that Goku may have become seriously desperate to defeat Cell with Krillin saying "Goku's crazy but he's not that crazy". Goku then used the Instant Transmission technique to teleport right in front of Cell and discharged the blast on him which blew more than half of Cell's body off and it had vaporized most of Cell's body. During this time The Z Warriors rejoiced as they believed Cell was defeated until he quickly regenerated and seemed content to continue what he called "A spectacular match" however after seeing this Goku realized that if he continued he would destroy the Earth or he and Cell would die fighting. Goku proceeded to shock everyone by forfeiting the match and reasoned that there was actually someone who could defeat Cell, Goku shocked everyone by stating that Gohan is the one who can defeat Cell and is the one he picked to fight Cell next and the Z Fighters were clearly upset and utterly furious most noticeably Piccolo and Vegeta and typically Cell was amused.
It took quite a while for Gohan to eventually agree to fight and most noticeably for him to become serious. Gohan fought just as well as Goku did and as a Full Powered Super Saiyan he managed to hold his own however The Z Fighters were obviously worried with the exception of Goku who had full confidence that his son could defeat Cell. As Gohan's fight with Cell continued, Gohan continuously told Cell to stop fighting pointing out that the violence was pointless however those words were heard by deaf ears as Cell ignored Gohan's words completely as Gohan began to tell Cell that his latent power if unleashed could seriously kill Cell and destroy everything however that statement only further interested Cell who began to torment Gohan so that he would become angry and unleash his true power so that Cell could see what he could truly do much to Gohan's own horror. Finally not being able to bear watch Cell torture Gohan, Android 16 rushed towards Cell as he wrapped his arms around his torso and threatened to use his self destruct device to kill Cell and himself (suicide) however Krillin quickly informed Android 16 that the self destruct device had been removed long ago by Bulma during repairs. Cell then proceeded to completely destroy Android 16 with the exception of his head that rolled over the battlefield, Cell the continued to say that even if Android 16 had used the bomb it would not have affected him much even though Cell was fearful when he discovered what Anrdoid 16 was intending to do.
After this Cell did the most bizarre act he has so far as he created 7 miniature blue versions of himself from his tail which he called The Cell Jr.'s and after they were born he ordered them to attack and severely beat The Z Fighters but not kill them, he did this so that he could anger Gohan in order for him to show him his true power as Cell found that Gohan's own physical pain will do no good so he decided to see what the pain of the people he cares about will do. Each Cell Jr. nearly had the same power level as Cell. Only Piccolo, Vegeta and Future Trunks in their Super Saiyan 2nd Grade forms managed to fight them and gain the upper hand for a while however they were eventually brutally beaten up by the Cell Jr.'s and even Goku who was weakened from his battle with Cell was severely beaten. Gohan was forced to watch his friends and family be beat up by the malicious minions of Cell as he quickly became truly angry however it was not enough to cause his true power to surface. Cell noticed Gohan's anger and quickly ordered the Cell Jr.'s to kill everyone, Hercule then discovered that the head of Android 16 could still talk, Android 16 then told Hercule to toss near Gohan and Hercule reluctantly did as he was told as Anrdoid 16's head was tossed between Gohan and Cell.
Android 16 proceeded to give words of encouragement to Gohan telling him that sometimes it is okay to fight in order to protect loved ones and protect the nature and animals he loved. Cell overheard the conversation as he claimed that they were good words of advice and then crushed Android 16's head under his foot. This act of cruelty finally caused Gohan to snap, Gohan now enraged to the very limit ascended to a Super Saiyan 2, a slightly tearful Super Saiyan 2 Gohan proceeds to mercilessly kill all of The Cell Jr.'s and Gohan's act quickly impressed and pleased Cell. The amazed and astonished Z Fighters watch in awe except Goku as Gohan now as a Super Saiyan 2 battles the powerful android Cell.
As the fight progresses Gohan gains complete control over the battle much to Cell's irritation and frustration. In a moment of intense rage and frustration Cell powers up and reaches his maximum power and delivers a hard punch to Gohan's face and two everyone's amazement who believed Cell was fighting at full power when he fought Goku moments ago Gohan was not even phased by the punch and with simply 2 punches he nearly incapacitated Cell. Cell quickly began to show fear when Gohan began to effortlessly dodge all of Cell's attacks, easily overpower him and even counter Cell's most powerful Kamehameha at blank point range with his own Kamehameha and when Goku quickly told Gohan to finish him off, Gohan showed a truly sadistic manner and persona as he refused to do as Goku said and proceeded to say that "Cell needs to suffer more" as he began to show slight enjoyment in Cell's suffering. Gohan began taunting Cell much to Cell's humiliation, in a state of uncontrollable rage Cell transformed into his Power Weighed form making the same mistake Future Trunks made by trading his speed for power making him unable to hit Gohan, Gohan ceased his dodging and kicked Cell in the face and then delivered an extremely hard kick to Cell's stomach, the kick was hard enough for Cell to regurgitate Android 18 causing him to revert to his Semi-Perfect form.
Enraged at the outcome of the battle, Cell threatened to destroy the Earth as he began to self destruct. After seeing this Goku stepped in being the only one who knew what to do, Goku used the Instant Transmission as he teleported himself and Cell to King Kai's planet that was then destroyed along with them. In a state of anguish the Z Fighters knew that Goku did what he did for the planet however suddenly a strong wind began to blow as a powerful force was felt everywhere and the force revealed itself to be Cell who was back to his Perfect form only more powerful and in a Super Perfect form, Cell then launched a death beam as it impaled Trunks through the chest, killing him in the process. Cell was able to return to his Perfect Form because the cells in his brain restored the memory of his Perfect Form. Cell had become much stronger because of his Saiyan cells and he was so strong that he referred to himself as "Ultimate Perfection" known by many fans as "Super Perfect Cell". Gohan was actually pleased to see Cell return hoping to avenge his father however Vegeta suddenly charged towards Cell in rage after seeing Trunks his own son killed, Vegeta now a Super Saiyan launched a merciless barrage of energy blasts that had no effect on Cell who simply stood there and proceeded to knock Vegeta to the ground with a simple blow that nearly killed him, in a rare moment Vegeta apologized to Gohan as Cell decided to finish Vegeta off as he launched a powerful energy blast however Gohan quickly jumped in the way as his arm was heavily damaged and broken and rendered useless. Cell pleased at the sight leaped back and began to power up for a Super Kamehameha that he claimed would destroy the entire Solar System, Gohan now had lost all hope and was ready to die.
Goku suddenly began to communicate with Gohan from Other World giving him words of encouragement enough for Gohan to power up and launch a single hand Kamehameha and he engaged Cell in a Kamehameha struggle as neither was pushing the latter' energy blast back. Goku continuously encouraged Gohan enough for Gohan to use his full power in the struggle however it was still not enough as Cell's power began to grow even more, all of the Z Fighters except Vegeta attempted to help Gohan by launching attacks however they were knocked away by Cell's energy. As all hope was lost and Cell began to overpower Gohan he was on the verge of winning Vegeta mustered up all of his pride and powered up to the maximum limit as a Super Saiyan and he launched an energy blast that momentarily distracted Cell who lost concentration and was knocked of balance, Gohan seeing the open opportunity immediately overpowered Cell and ultimately defeated and killed him as Gohan's Kamehameha pushed Cell's Kamehameha back until such time that Cell was completely vaporized by Gohan's attack and the world was now in peace.
Cell's main power is to absorb other life forms to add to his own energy and body. He uses this mainly to absorb the people of Earth once he first arrives in the timeline. After that, his power of absorbtion is used to capture and absorb Android 17 and then Android 18. He is also capable of ejecting miniature and equally powerful versions of himself from his tail, but only in his perfect form. Possessing cell's from the Z fighters, Cell has use of techniques seen all throughout the series including the powers from several villians such as Freiza and Nappa. Cell also has the power to activate a self-destruct sequence in his body that would blow up an entire planet. Other noteable techniques that Cell possess include:Instant Transmission (Shunkan Ido)-Cell acquires this technique from Goku after Cell self explodes, destroying King Kai's planet.Solar Flare (Taiyo-ken)- Technique originally used by Tenshinhan, Cell uses it to aid in absorbing Android 18. Multiform Technique (Shishin no Ken)-Technique in which the user splits into four, Cell uses this while fighting Goku. Telekinetic Abilities- Cell has shown the ability to move easily move large objects with his mind.
Imperfect Cell - Cells initial form, which is the form he has before he absorbed any of the androids. While in this form, he can absorbs many humans for energy in this form. Even though this is Cell's initial form, it was strong enough to kill Future Trunks and steal his time machine to travel back in time to where the Android 17 and Android 18 were still intact. Cell has green skin on the arms, legs and twist. In this form, Cell has two wings. Cell also has long tail which is can be used to attack his opponents, but mainly used to adsorb human beings and the Androids.
Semi-Perfect Cell - Cell achieves this form after absorbing Android 17. Cell's body mass increase and has a figure that is more human-like, he even has an actual mouth. Cell still has his tails but he loses his wings. After absorbing Android 17, his power greatly increases but his power was still no match against Vegeta in his Saiyan form. Knowing that he cannot defeat Vegeta with his Semi-Perfect form, Cell uses Saiyan's nature as advantage and tells Vegeta that will get stronger if Vegeta lets him go and absorb Android 18. Vegeta allows him to escape and Cell proceed to absorb Android 18 who was still trying to escape from Cell.
Perfect Cell - His completed form, he achieves this form by absorbing Android 18. As promised he continues to fight against Vegeta but it turns out Vegeta was out his league. When Vegeta became unconscious Future Trunks tried to defeat him as well but it turned out to be futile as well. His wing grows back but his tails gets shortens. The tail is now located on his back, removing the ability to absorb other beings, but from where his tail is located Cell can produce miniature version of himself called Cell Jr. which is weaker than him but still strong enough to give hard time to the Z fighters. In his new form, his body consists colors of black, green and white. His face became close to human's face as well. Confident in his power Cell starts The Cell Game which game all the fighter ten days to train. In the end only one who could defeat him was Gohan.
Super Perfect Cell - Cell's strongest form, which he ironically achieves this after reforming from blowing himself up sacrificing Goku. Despite spitting out Android 18, Super Perfect Cell is identical to Perfect Cell with the addition of a lighting charged aura, similar to that of a Super Saiyan 2. Even though he was easily beaten by Gohan in his Perfect form, his Super Perfect form gave him more power, making harder for Gohan to fight against him. So proud his form, he threatens to destroy the entire solar system with his ki beam. Later he was defeated by Gohan's Kamehameha blasting in to little pieces until there was no trace of him left.
Cell appeared once more in Dragon Ball Z a few episodes after the end of the Cell Saga. He is seen in hell with other villains from the series torturing the gatekeepers of Hell to let them escape. He also makes an appearance in Dragon Ball GT when other villains from the past have been resurrected.
