Bio-Androids are a species of Android enemies in Dragon Ball Online. The original member of the race, Cell, debuted with in Dragon Ball Z. The race was recreated when the clone of Cell, Cell-X, moved to a cave behind a waterfall on Papaya Island and spawned many Cell eggs which hatched into variations of Cell's forms.



The original Bio-Android Cell is composed of the cells of Saiyans, Namekians, and members of Frieza's race that he may have passed to his offspring, clone, and clone's offspring. It is unknown what cells the Dragon Ball Z: Attack of the Saiyans Bio-Androids and Genome are made from, since they are not confirmed to be related to Cell. Because of the Bio-Androids' organic nature, they are the only known Android model to be able to be sensed via Ki Sense.

Additionally, it is implied that Cell-X and it's Bio-Android offspring lack Goku's DNA.

The New Type Android 21 possess the DNA of the Dragon Team, Frieza, Cell, Majin Buu as well as numerous Human-Type Earthling researchers.

The demonic Bio-Metal Mira is primarily of the Earthling and Demon Realm races, but also possess the DNA of several other races.

Bio-Android Eggs

The sentient eggs of Cell-X which appear in Dragon Ball Online are spiky, have one eye, small wings, and are colored brown, green, or purple. They eventually hatch into Larval Bio-Androids.

Larval cells

Larval Bio-Androids

The form that most members of the race takes when they are first born, this from eventually matures into an Imperfect Cell. They are colored brown, green, or purple in Dragon Ball Online.

Imperfect Form
Imperfect cells

Imperfect Bio-Androids

A form displayed by Cell in his original appearance, this is Cell's mature form without having absorbed the Androids. Future Cell was stuck in his Imperfect form due to the destruction of the Androids of his timeline. Imperfect Bio-Androids are also grown versions of Larval Bio-Androids in Dragon Ball Online; they are colored green or purple. The Attack of the Saiyans enemies Sandman, Yorgan, and Failed Experiment are slightly modified and recolored versions of Cell in his Imperfect From. In his normal states, Genome is in an imperfect form.

In Xenoverse 2, Perfect Cell is shown to be able to birth mature Imperfect offspring identical to his Imperfect form in appearance and personality. He creates one while training the Future Warrior as an instructor to act as a sparing partner to better gauge the Warrior's power.

The species is revived when Cell is brought back by the Time Breakers as "Cell-X". Cell-X headed to a cave on Papaya Island, where he spawned many Cell eggs which hatched into variations of Cell's forms. Cell-X has his children collect more energy for him.

Xenoverse series

Main articles: Dragon Ball Xenoverse and Dragon Ball Xenoverse 2 Cell and the Cell Juniors appear as historical figures and Chronoa allowed Cell's alterations to history remain as part of the official history like she had with Future Trunks' as Cell's Time Machine played a critical role during the conflict with Goku Black and Zamasu. Additionally, Cell was ultimately killed by Gohan while Future Trunks prevented Future Cell from stealing his Time Machine and Present Cell was never completed in the main timeline as he was killed by Future Trunks and Krillin.

However in one Parallel Quest in Xenoverse 2, Cell's Time Machine goes off course and ends up during the Cell Games resulting in Imperfect Cell encountering Perfect Cell and the Cell Juniors. Imperfect Cell is pleased to discover the Supercomputer was right about his perfect form, while Perfect Cell looks down on his Imperfect self even calling him an idiot for ending up in the wrong timeline. Imperfect Cell even hopes to absorb Perfect Cell in the hopes he will become more perfect and manages to defeat his Perfect self and the Cell Juniors with the assistance of the Time Patrol but Time Patrollers interrupt the mission and Super Saiyan 2 Gohan and the mission ends once he is defeated thus it is unknown if Imperfect Cell was able to absorb Perfect Cell and if it would have made him more perfect as he believed. While training the 2nd Future Warrior as an Instructor, Perfect Cell is shown to be able to give birth to clones of his Imperfect form (similar to Cell-X though the result is an Imperfect Cell identical to Cell's imperfect form) which he uses to help train the Future Warrior during one lesson.

"You know, who was that strange little youngster? I'm suddenly overcome with a great sense of unease... The power signature is neither demon nor human. It feels... constructed. Hmm. This is disturbing. If the scientific knowledge that can create a life force that powerful exists, I want it in my army!"
— Lord Slug comments to the Future Warrior after an encounter with Cell Jr. in Dragon Ball Xenoverse 2

Lord Slug senses several powerful warriors while training the Future Warrior and decides to investigate it as part of their next lesson. They encounter a group of Cell Juniors which Lord Slug tasks them with defeating before sparring with the Future Warrior himself. After completing the lesson, Lord Slug is filled with uneasiness by the power of the young Bio-Androids which he notes is neither demon nor human, before concluding it feels artificially constructed. However he notes that if scientific knowledge exists that can create a life force as powerful as theirs then he wants it for his army, implying that he wishes to obtain it to create his own Bio-Androids like the Cell Juniors (as he does not encounter their progenitor the original Bio-Android Cell whom he would probably recognize as a threat, thus explaining his uneasiness as he fears it may potential be a power beyond his control) though he is right to be disturbed by the power Bio-Androids possess as he likely recognizes that it could potentially exceed his own causing him to view them as a potential threat while desiring their power in his army if it can be bent to his will (just as with the Future Warrior). As they are partially Namekian and evil, Slug might also fell some kinship towards them as he also expresses a desire to recruit strong Namekian warriors into his Demon Clan.


Main article: Dragon Ball FighterZ Android 21 is a new type of Bio-Android created by Dr. Gero's Supercomputer. Using the cells of powerful fighters and Earth's most brilliant scientific researchers, Android 21 exceeded the power of Cell and became the leader of new incarnation of Red Ribbon Army. However Android 21 was good natured and instead used her brilliant mind to restore Android 16 in an attempt to recreate the family she had lost in her previous human life which she often fantasized about. Unfortunately, the incorporation of Majin Buu's cells caused her to develop an insatiable hunger and an evil split personality that cared nothing for anyone but herself and saw all other beings as food for her to hunt. With the aid of the reconstructed Android 16, Android 21 worked to develop a way to use the soul linking system developed by Dr. Gero to link with a soul strong enough to help suppress her cravings. However the evil side had created countless clones of the Z Fighters, Nappa, the Ginyu Force, Cell, and Kid Buu which she unleashed upon the Earth, while the Earth's fighters were incapacitated by power suppressing wave machine that had been developed by Dr. Gero. Additionally 21 revived Nappa, the Ginyu Force, Frieza, and Cell using the Namekian Dragon Balls which were then linked with artificial souls (though in the Enemy Warrior Arc, Frieza is accidentally linked with a human soul allowing him to free the other villains from 21's control before allying himself with Cell and the Z Fighters due to the threat posed by 21).

In the first two arcs, Android 21 succumbs to her evil side completely and kills Android 16 for opposing her evil plans before she is ultimately destroyed by Goku and his allies. However in the Android 21 Arc, when the evil side activates the power suppressing waves it causes her good side to resurface and with Android 16's help she manages to bond a human soul with Android 18 as part of a plan to help suppress both her urge to feed and her evil side. She joins forces with the soul, Android 16, 17, and 18 in order to eliminate the clones, though 17 and 18 notice her growing hunger and during one of her episodes Android 18 asks the soul to link with 21 to stop her, leading the soul to help her good side repress her evil side. Android 16 reveals that they planned to have her link with soul in the hopes that it might be able to suppress her evil side and urge to feed which resulted from some of her cells going out of control, causing the twins and the soul to agree to help 21 understanding her plight. However when they are confronted by the original Cell, Android 21 decides to join the fight to protect 16, 17, and 18. Though she manages to defeat Cell, the soul is unable to suppress her hunger. When Android 16 tries to stop her from absorbing Cell, she kills him (though her evil side is apparently resurfaces). The death of 16, causes her good self to resurface. Her grief and guilt over 16's death causes 21 to subconsciously use fission to split into her good and evil halves. The evil 21 having inherited most of her power, absorbs Cell which causes her to transform into a more powerful form that inherits Cell's spots and causes her skin to become darker. The good 21 though weaker remains determined to stop her evil half joining forces with the linked soul, 17, 18, and the Z Fighters to stop her. Though she is able to suppress her hunger, Good 21 fearing she will one day lose control, decides to sacrifice herself to help her newfound friends destroy her evil half ending the threat both posed. In honor of her sacrifice, Goku decides to ask King Yemma to reincarnate her soul as he had with Kid Buu's, implying 21 would be reborn as a human like Uub.

Due to the incorporation of Majin Buu's cells, Android 21 possesses traits similar to female Majins though with additional traits such as hair (due to the influence of her Earthling and Saiyan cells), a tail (due to the influence of Frieza's cells), and pointy ears (presumably due to the influence of her Namekian cells). Due to her Namekian, Majin, and Bio-Android Cells she possesses extremely powerful regenerative capabilities. She can grow stronger via turning people into sweets and consuming them, though due to Majin Buu's cells being unstable she develops a destructive and insatiable hunger that causes her to lose control of herself. While her evil side embraces her hunger which causes her to slowly descend into madness, her good side recognizes the danger her and her evil counterpart's hunger poses to other and does everything she can to stop it from consuming her, even if it means sacrificing her own life in the processes. If Android 21 and Cell are on a team, she notes that both she and Cell are Bio-Androids, though she is a different more advanced type of Bio-Android as she is both powerful and extremely intelligent (as shown by her reconstruction of Android 16, her knowledge of cloning, and the use of Dr. Gero's technology) making her far more dangerous as a result. Her high intelligence is likely the result of her being created from the cells of various scientific researchers as it is implied her purpose was to lead a new incarnation of the Red Ribbon Army to conquer not only Earth but galactic conquest as well as Evil 21 does not dismiss the idea though it remains secondary to satisfying her hunger.

Ironically, Cell was in a sense lucky Majin Buu was not around before he was completed, otherwise he too may have suffered from the same insatiable hunger as Android 21 which was her greatest weakness as it effected her mental stability due to the uncontrollable nature of Majin Buu's cells as demonstrated by Android 21 and the Kid Buu clones.


Semi-Perfect Form

Main article: Form Change The Semi-Perfect form is a form that is only used by the original Cell, as it is a midway between Imperfect and Perfect that can only be obtained when he absorbs one of the Androids.

Genome as a Perfect Bio-Android after using the Super Class-up

Cell attains a perfect form after absorbing Android 17 and Android 18. Cell Juniors (the offspring Cell) and Cell-X Juniors (the perfect offspring of Cell-X) also have perfect form since their birth. After using the Super Class-up, Genome possess a perfect form.

Cell's counterparts Present Cell and Future Cell never achieve their Perfect form in the manga or anime, but both take it in video games.

Saiyan Forms

Main articles: Super Saiyan, Super Saiyan Third Grade, Saiyan Power, Super Saiyan 2, Berserk, and Super Fu Bio-Androids who are part Saiyan can utilize their Saiyan traits to achieve new forms.

Thanks to his Saiyan cells Cell can utilize the Super Saiyan form and it's third grade. He uses the Super Saiyan form when powered up and fighting.

After surviving a near death experience Cell achieves his Super Perfect form, which is his version of Super Saiyan 2. It is a significantly more powerful version of Cell's Perfect form. Although all of Cell's other forms changed his appearance drastically, this form only increases his energy output to a degree where his "skin" becomes a lighter shade and his aura crackles with bio-electricity.

The demonic Bio-Metal Mira gains the Super Mira form through anger thanks to his Saiyan cells. Upon absorbing his creator Towa, Mira gains a form that resembles a tailless Super Saiyan 4 with silvery white fur presumably due to the influence of his Saiyan cells. Fu inherits the Super Mira form from Mira whom is his genetic "father" as Fu is Mira and Towa's artificially created genetic offspring. Damira also inherits Mira's Super Mira form as a permanent transformation triggered by Dabura and Mira's EX-Fusion.

Mira also gains the form by destroying his power limiter that keeps his enegy from overloading his body though in doing so he runs the risk of meltdown triggering him to self destruct which Towa theorizes could destroy the universe possibly even breach dimensions destroying the Multiverse or other timelines forcing Towa to consider working with the Time Patrol to subdue Mira to avert disaster.
