Android 18

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. However, 18's sense of humor is not always tactful, as she jokingly expressed to Future Trunks that she wanted reimbursement for him killing her alternate universe counterpart, much to Future Trunks' displeasure. This is a rare instance where Android 18's humor was anything but tactful, as per her usual timing. This failure is likely due to Android 18 being unaware how murderous her counterpart was and how much Future Trunks had suffered because of it, as she likely would have been more sensitive had she known the full extent of the destruction and suffering caused by her and her brother's counterparts. She is also shown to be rather prideful, though not to the same extent as her brother had been during the Imperfect Cell Saga.

As an older sister and delinquent, and later as a wife and martial artist, Android 18 is shown to be outwardly commanding, insisting that she and her brother 17, and later she and Krillin, have to make strides to improve the family's financial situation, insisting Krillin to join the Tournament for the prize money, forcing Mr. Satan into a deal about giving her 20 million Zeni to the point of destroying his property and cowing him into multiplying the prize money a hundred-fold, wanting Shenron to grant her wish for a present for Krillin, and initially saying that she would only fight at the Tournament of Power if she gains a large sum of money for it although she later decides to enter because she suspects that the tournament is not really a game.

Appearance: When she is married to Krillin and living at Kame House, she wears a pale blue buttoned-up denim vest, white jeans, red hoop earrings along with a red bracelet on her left hand, and black flip-flops. Her blue eyes had a slightly darker coloration than last time. Later, at the World Martial Arts Tournament and throughout the Buu Saga, she wears a black shirt with white and black striped long sleeves, blue jeans, a brown belt, and black flats with orange socks. It is noticeable that this outfit incorporates between her first outfit in the Androids Saga and her third outfit in the Cell Saga as the shirt, belt, and color scheme is taken from her first outfit, while the jeans and flats are taken from her third outfit.

At the end of Dragon Ball Z, she cuts her hair shorter which resembles Bulma's bowl-cut hairstyle from the Majin Buu saga and wears fashionable business attire. Her outfit is a red sleeveless shirt, pale yellow business pants, the pale gold hoop earrings she had initially worn during the Androids and Cell arcs, the same gold bracelet on her left wrist which she had worn during the Cell arc, and brown flats. She also wears the pearl necklace that she previously wore during Imperfect Cell Saga and the Cell Games.

Her main look in the Peaceful World Saga was retained for Dragon Ball Super: Super Hero and wears her tracksuit in the Universe Survival Saga but with minor changes being the change to above ankle length gray with pink stripes jogger pants and a new pair of black sport shoes. Her jacket is magenta, her trousers resembling a sports capri which is light grey with pink linings. She also retains her grey shoes with white soles and fuchsia pink socks.

For the Universe Survival Saga, she wears a pink tracksuit identical to Gohan's during Frieza's invasion of Earth, and grey shoes with white soles.

In Dragon Ball GT, while being the servant of Baby and later cured with the Sacred Water, she wears a red long sleeve turtleneck shirt, black pants, silver hoop earrings, pearl necklace and red flats. Her short hair had finally grown out and was styled into a short bob.

In the Super 17 Saga, she wears a purple business suit jacket with a pink short sleeved undershirt, purple business pants, gold hoop earrings, pearl necklace and red heels. She also retains her hairstyle from the end of Dragon Ball Z. While facing her twin brother for the second time, she was later seen without her business suit jacket and the pearl necklace on her neck as a black strapless bra is shown underneath her pink short sleeved shirt after she angrily rips half of her shirt while taunting her twin brother to kill her.

At the end of Dragon Ball GT, she was seen wearing her pink short sleeved shirt, reddish brown pants, and red flats.

Krillin's courtship of 18 beyond was not shown but it is clear, by the time Majin Buu surfaced, that 18 had consented to marry Krillin and even had a daughter with him.
