Android 18

Android 18 (人造人間18号) is a fictional character in the Dragon Ball manga series created by Akira Toriyama. Android 18 makes her debut in Chapter #349 "The Androids Awake!", first published in Weekly Shōnen Jump on November 12, 1991.

She and her twin brother, Android 17, were forcibly turned into cyborgs by Dr. Gero to serve his vendetta against Goku. The main-timeline version of the character has very little to no interest in fulfilling Gero's orders and becomes a major character in the series after marrying Goku's best friend Krillin.

In an alternate future timeline, Android 18 is a ruthless killer who started a reign of terror along with Android 17 over Earth that lasted for twenty years until they are both killed by adult Trunks.

Creation and conception
Android 18, along with Android 17, were conceived after Akira Toriyama's former editor Kazuhiko Torishima expressed disapproval with Androids #19 and #20 as villains. Following their introduction into the series, Torishima soon afterward became dissatisfied with her and 17 as well, resulting in the creation of Cell. Toriyama stated that he was pleased with Android 18 because she was a type of girl he had not drawn before, and that he liked her slanted eyes. In 2014, he revealed her real name was.

Yūsuke Watanabe, who wrote the screenplay for the film Dragon Ball Z: Battle of Gods, had originally written the film to take place at Android 18 and Krillin's wedding, but Akira Toriyama wrote it to take place at Bulma's birthday party. Watanabe thought Toriyama made the change because he wanted fans to imagine the wedding for themselves. In promotional material for Battle of Gods, Toriyama drew her with purple hair.

Voice actors
In the Japanese version of the entire Dragon Ball anime series and subsequent related media, Android 18 is voiced by Miki Itō.

In English, Android 18 is voiced by Meredith McCoy in the Funimation dub of Dragon Ball Z and Dragon Ball GT except for Dragon Ball Z Kai, where she is voiced by Colleen Clinkenbeard. However, since Battle of Gods, Meredith has returned to the role. In the Ocean Group dub of the Cell arc, 18 was voiced by Farrell Spence, and later by Willow Johnson in the Buu arc. In Bang Zoom! dub, Android 18 is voiced by Tamara Ryan.

Abilities
Despite being referred to as an Android or Cyborg and commonly regarded as such, Android 18 is practically neither. Bulma stated while looking at 17's blueprint that he and 18 were human-based, but just about everything has been enhanced with bio-organic components. Her only mechanical parts are the emergency deactivation controller, a self-destruction device (removed), and a small perpetual energy reactor that provides her with inexhaustible energy and stamina.

Dragon Ball Super reaffirms this, with Gohan stating that the androids have been modified on a cellular level to be superhuman. Furthermore, Gero's experiments on her do not impede her ability to reproduce, as evidenced by her giving birth to a healthy daughter, Marron.

In Dragon Ball Z
Prior to their introductions and present in both timelines, Androids 17 and 18 were converted into androids by Dr. Gero with the intent of murdering Goku. In the main timeline, Android 18 is activated by Dr. Gero along with Android 17 after he returns to his laboratory following his unsuccessful attempt to defeat Goku's allies. After Gero is killed by Android 17, Android 18 activates Android 16 following surviving a blast meant to kill her from Trunks and the three begin their quest to find and kill Goku. When they encounter Vegeta, Android 18 decides to fight him and easily bests him in battle, receiving only damages to her clothing and breaking his arm. When Trunks, Tenshinhan and Piccolo become involved, she and Android 17 easily defeat the trio. Before leaving to continue her quest, she kisses Krillin on the cheek. The androids go to Goku's home and do not discover him there, leading them to journey to Master Roshi's house, but they do not find him there either due to his having departed not long before. 18 watches Android 17's battle against Piccolo, at one point becoming impatient and offering her assistance to her brother's decline, until Cell arrives, who reveals his intent to absorb the pair. Piccolo is dispatched by Cell and Android 17 is absorbed, Android 18 nearly being convinced to be absorbed as well by Cell's impersonation of Android 17 until he mistakenly mischaracterizes him. Androids 18 and 16 are given time to escape thanks to Tenshinhan holding Cell back. She and Android 16 hide on an island after this, where she refuses to leave his side and watches Vegeta's fight against Cell before Krillin approaches her with a remote to turn her off. He destroys it, realizing his love for her, and Android 18 is soon afterwards absorbed by Cell who blinds everyone with, allowing him to reach his final form. For the next ten days, until the Cell Games tournament that Cell sets up following his disillusion with the strength of both Vegeta and Trunks, 18 remains trapped and unconscious inside of his body. However, a strong blow from Gohan causes him to regurgitate her. After Gohan defeats Cell, she is healed and declines Krillin's advances for the time-being, despite him using the Dragon Balls to have her self-destruct device removed.

In the timeline that Future Trunks comes from, 17 and 18 are mass murderers whereas the main timeline versions of the pair never killed innocents. They are identical in appearance to the versions of the two in the present timeline, Android 18 wearing the ensemble she wore in the main timeline upon her activation by Dr. Gero. Within the months of their release, shortly after the death of Goku, they kill their timeline's versions of Piccolo, Vegeta, Krillin, Yamcha, Tien and Yajirobe, Gohan managing to escape. Several years later, they kill Gohan and then nearly kill Trunks three years later when he confronts the pair during one of their killing sprees. When Trunks returns from the past, now vastly stronger than he was in their previous encounter as a result of his training, she shows interest in finally ending his life after he confronts her and Android 17, but is killed by him instead.

Seven years later in the main timeline, she has married Krillin and has a daughter with him named. She convinces Krillin to participate in the 25th Tenka'ichi Budōkai for the money along with her. Thanks to a lack of interest in being exposed as super-powered, she disguises her strength in hitting the Punching Machine, hitting it lightly and thereby altering who she is matched to fight. During the competition, she competes against Goten and Trunks when the pair enter the competition as, having stolen the identity of another competitor. After the duo reveal themselves by transforming into Super Saiyans, Android 18 wins the match by default, advancing to the next round against Mr. Satan, who she outclasses in strength, but throws the fight nonetheless after she secretly arranged to have the prize money shared with him so as not to ruin his reputation. After Majin Boo is released, thanks to the energy used by both Goku and Vegeta while the two fought, Android 18 joins the others in searching for the Dragon Balls to resurrect everyone killed by Vegeta and resides at Dende's while taking refuge. After Boo finds them the following day, kills the majority of people on Earth and escapes the Room of Spirit and Time, leaving Gotenks and Piccolo inside, Android 18 is killed alongside her daughter when they are simultaneously turned into chocolate, being eaten by him afterward. She is later brought back to life and gives energy to Goku's Genki-dama, successfully destroying Majin Boo. Ten years later, 18 is last seen attending another Tenkaichi Budōkai.

In Dragon Ball Super
in the film Dragon Ball Z: Battle of Gods, Android 18 is present at Bulma's birthday party, attempting to fight Beerus following him being enraged by Boo taking his pudding, but being defeated with a single strike to the neck; in Dragon Ball Z: Resurrection 'F', she shaves Krillin's head before he goes off to fight a resurrected Freeza, being killed after Freeza destroys the planet but having her death undone when the timeline is reversed. After the events of the last two films, she informs Krillin of a supposed space picnic, leading to his investigation into the matter and she later travels off Earth to watch the tournament between the fighters from her universe and those of Universe 6. After Trunks returns from the future, he discovers Android 18 and Krillin's marriage, meeting 18 again and preparing to engage her before she greets him. Android 18 later wants to get a gift for Krillin and unsuccessfully tries using the Dragon Balls. Android 18 scolds Krillin for being injured by a bullet while he is reluctant to train with Goku, later citing her as a factor in his choice to resume training.

Android 18 and Krillin are approached by Goku and Gohan to join the Tournament of Power, 18 agreeing due to the 10 million Zeni reward and revealing Android 17's location. During the tournament Android 18 chooses to fight on her own, defeating Universe 9's Sorrel, Universe 4's Shosa, and Universe 11's Tupper. Rozie and Ribrianne launch a combined attack at Goku that Androids 17 and 18 deflect, the two then battling Rozie and Ribrianne. Android 18 knocks Ribrianne out of her transformation and she reverts to Brianne, who catches Android 18 in an energy trap while her comrades from Universe 2 send their love to her and enable her transforming back into Ribrianne but with an increase in size. Android 18 concedes that she is finished before hearing Krillin screaming her name from the sidelines and breaking through Ribrianne's trap. With assistance from Android 17, 18 blasts through Ribrianne's giant form and eliminates her. Universe 3's Paparoni and Koichiarator merge to form Anilaza and Goku, Gohan, Vegeta, Frieza, 17, and 18 attempt coordinating their attacks against the being. Anilaza attempts to eat 18 before Goku intervenes, and Anilaza corners Android 17 with a series of beams that lead him off the ledge of the arena. Android 18 jumps off and grabs him, telling him that the rest is up to him before kicking him back to the arena while descending to her own elimination. She apologizes to Universe 7 for being eliminated and tells Android 17 he better not lose.

Shortly after the Tournament of Power, 18, along with 17, help the Z fighters fight off henchmen that Moro has sent to Earth. She, along with the other allies, lends Goku some of her power in order to finish off Moro once and for all. Years later Android 18 is approached by Piccolo to follow him to the new found Red Ribbon army base and along with Gohan, Piccolo, Krillin, Goten, and Trunks. There she participates in the battle against Cell Max, a revamped version of Cell created by Dr. Gero’s grandson, Dr. Hedo.

Reception
Android 18 is a generally well-liked character, praised for her status as the sole female character to physically compete with the male cast for a time as well as her personality. In a 2004 poll among Japanese fans, Android 18 was voted the tenth most popular character in the series. Her relationship with Krillin has also been met with favorability among commentators. Sheldon Pearce of Complex dubbed her the "most compelling" of the androids and credited her with keeping Krillin a relevant character after her introduction. David F. Smith of IGN believed the subplot of the relationship between Android 18 and Krillin helped to keep the Cell arc "a little more interesting". Smith ranked the development of the relationship #6 on his list "Dragon Ball Z: Top 10 Plot Twists". However, Android 18's role in the franchise past the Cell storyline has been met with mixed reception. Android 18 was ranked #4 on Santiago Rashad's list "Top Ten Misused Dragon Ball Characters" who felt that she was underused barring two later films, Bio-Broly and Battle of Gods, and that she was possibly used less due to not being a Saiyan. Aaron Hubbard of Moviepilot observed her shift from fighter to mother and wife as "unjust" given that she had been a threat to the protagonists in her first appearances, though still thought highly of the character. Chris Homer of The Fandom Post felt Android 18's "getting in the spotlight" was one of the decent moments in the Super 17 storyline.

Android 18 is a popular subject for cosplay activities by Dragon Ball fandom. Japanese mixed martial artist Itsuki Hirata has cosplayed as the character on at least one occasion. She was the visual inspiration for the Fatal Fury and The King of Fighters character Blue Mary. American mixed martial artist Ronda Rousey revealed in 2015 that she wanted to be Android 18 when she was a child.
