Android 21 and 18

Android 18 (人じん造ぞう人にん間げん１８号ごう Jinzōningen Jū Hachi-Gō, lit. "Artificial Human No. 18"), originally named Lazuli (ラズリ Razuri)[4] when she was an ordinary human, is the older twin sister of Android 17 and Dr. Gero's eighteenth android creation, designed to serve Gero's vendetta against Goku. While her interests do not initially deviate from this expectation, her curiosity to activate Android 16, in spite of Gero's orders not to do so, leads Android 17 to take it upon himself to rebel and murder Gero. Eventually, Android 18 becomes a member of the Z Fighters, as well as the wife of Krillin and mother to their daughter Marron.

Android 18 is a slender, athletic and beautiful woman of above-average height and fair complexion. She has shoulder-length blonde hair, although its specific shade varied between light/golden[5][6][7] or platinum[5][8] that parts over her left temple, which she generally keeps tucked behind her ear. She consistently wears small gold hoop earrings on both ears. Her hair is apparently natural due to her not minding too much

Like her brother, Android 18 usually displays a cool and confident demeanor, especially in battle, although her sarcastic and biting humor is the most prominent trait of her personality. This is demonstrated when Goku takes notice of her assembly with the Dragon Team at the 25th World Martial Arts Tournament, leading to the retort "Look, he noticed. How cute." (In the Japanese version she says, "Took you a while idiot!"), as well as dryly saying "Spare me" when Krillin reveals to Goku that not only have they married, but also had a child. Shortly after this, she is asked by the World Tournament Announcer if her real name is legitimately "No. 18", to which she responds, "My father was pretty dull" (In the Japanese version, she replies that "It doesn't matter" before tossing the number at the World Tournament Announcer). Although she isn't characterized for this, 18 can be very curious if she is really interested in something, to the point of activating her comrade Android 16 and wondering what present she will give to her husband Krillin during a dispute of a wish with the others using the Dragon Balls. She often expresses herself in her cool and downplayed manner well into her marriage with Krillin, often smiling in a somewhat subdued fashion that conveys her very laid-back personality, in Super, however, she is often seen smiling.

Android 21 (人じん造ぞう人にん間げん２１号ごう Jinzōningen Nijūichi-Gō) is an Android whose template was Vomi. She appears as the main antagonist of Dragon Ball FighterZ when in her evil persona. Her intellect rivals that of Dr. Gero,[2] though she may be even smarter than he was.[3]

New Type Bio-Android (Human-type Earthling/Saiyan/Frieza Clan/Namekian/Majin hybrid) Gender Female Birth Date After Age 769 (creation or conversion)[1] Death: Age 830

Android 21 is described as a tall, curvaceous scientist with a very slender build, blue eyes and long bushy auburn hair. She wears glasses, has a gold ring on her left middle finger, and black nails. She wears a pair of hoop earrings, a sleeveless, short blue and red checker pattern high neck minidress with opaque black tights, matching black detached arm sleeves, and blue (left foot) and red (right foot) ankle heel boots with gold tips. She also usually wears a white lab coat (with the Red Ribbon logo on the left shoulder) with her outfit.

In her true form, Android 21 keeps her curvy body, her skin turns pink, her hair becomes white with a pink tint, her ears become pointed, her eyes changing depending on if her evil half takes over, and she gains a long prehensile tail. Her attire changes to a black tube top, keeping the black arm sleeves with gold bracelets at the ends, her boots become black, and also gaining white baggy pants. It's noted that she most resembles a Majin in this form. Her eyes slightly vary depending on which moral alignment she represents. In her good representation, she retains the eyes from her human form. In her evil representation, her eyes instead are more similar overall to that of a Majin.

Her appearance in her true form is the result of her having all of the traits of the Z Fighters, Frieza, Cell and Majin Buu rolled into one.

Due to her biology, Android 21 has a natural, compulsive instinct to feed (which grew out of control due to cells in her body going berserk). Like Majin Buu, she prefers sweets and confectioneries, her favorite being macarons. However, she has no control over her hunger and constantly fights to keep herself from turning others into treats and devouring them.
