Spoiler Warning: Spoiler details may follow.

Bio-Androids are a species of Android enemies in Dragon Ball Online. The original member of the race, Cell, debuted within 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.[1]

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. Fu possess all the DNA of Mira, as well as Towa, probably Mechikabura, as well as all of the other strongest fighters.

Life Cycle

Due to a lack of an official translation, some Dragon Ball Online content may not be entirely accurate.

The life-cycle of the Bio-Androids related to Cell.


Peculiar Egg (brown), Half-Adult Cell Egg (green), Cell Egg in Evolution (purple)

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.


Pure-Cell Larva Worker (green), Pure-Cell Larva Collector (purple)

A ki specialist Cell larva

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

Imperfect Form

Mutant First Form Cell (green) and Soldier Cell (purple)

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 green ones with blue skin are Multi-Purpose Cell. 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.


Bio-Androids like Cell feed upon other lifeform's bio essence which cell can absorb and incorporate into himself via his Tail which can regenerate thanks to his Namekian cells thus removing it will not inhibit his ability to feed or absorb others. Cell can either inject his tail into his victim's body to absorb their bio mass which causes them to shrivel up, leaving no trace of the victim but their clothing , accessories, or equipment they may be wearing or carrying. Alternately Cell can absorb the victim whole by expanding his tail, which is how he absorbs the Androids. Perfect Cell could also briefly absorb Goku during the Super 17 Saga presumably due to him regaining his perfect form after losing Android 18 thanks to the Saiyan Power boost from surviving his Unforgivable! self destruction, which presumably allowed him to retained tail's ability to absorb bio essence and other beings due to self destructing while in his Semi-Perfect form. However other sources indicate he loses this ability after absorbing Android 17 & 18. It is unclear if Cell or his offspring require any food or water to survive, though like Earthlings, Saiyans, and Namekians, Cell can digest a Senzu Bean.

Due to her Majin genetic heritage, Android 21 and her fissions' diet is omnivorous though consists primarily of sweets. Android 21 (when her evil persona or insatiable hunger consumes her) and Android 21 (Evil) will also turn other beings into food in order to absorb them, much like Evil Buu. However Android 21 (Good) refuses to turn others into food due to finding it morally reprehensible and for fear that she will eventually given in to her insatiable hunger. Like with King Gurumes Blood Ruby mutation, Android 21 and her fissions insatiable hunger effects her mental stability and it is implied her Majin cells were simply beyond the Supercomputer's ability to incorporate into her properly as their magical nature is presumably beyond the understanding of Dr. Gero's mortal science. However the Android Majin created by the Time Breakers in Dragon Ball Online lack this problem, indicating knowledge of Demon Realm science is required to create Majin Bio-Androids that lack insatiable hunger. Due to evil persona giving into her insatiable hunger, she like Moro sees other lifeforms as little more than food, though she prefers powerful natural born fighters as the clones she uses as a backup food supply to satiate her hunger test terrible due to their artificial nature. Additionally Android 21 (Evil) is capable of consuming inorganic materials such as the remote for the Wave Machine, though she notes that they taste disgusting.

Similar to Cell, Mira can absorb Damage Energy to grow stronger and in Mira's case his core can absorb it to restore his physical body if it is destroyed, though due to his immobility he requires Towa's assistance. Mira can also use Energy Absorption to absorb a target's power directly.

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 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.

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.


Main article: Dragon Ball FighterZ Android 21 is a new type of Bio-Android created by Dr. Gero's Supercomputer.[2] 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. While naturally good, 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. The evil side had created countless clones, including of Cell.

The evil 21 is able to absorb 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. 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.

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.
