Android 18 | Secured and contained

Android 18, formerly Lazuli, is a cyborg and character in the Dragon Ball manga and anime series Dragon Ball Z. Dr. Gero kidnapped and experimented on Lazuli and her brother Lapis, transforming them into cyborgs to serve his vendetta against Goku. Though commonly called an android, Android 18 is actually a cyborg with human-based origins and bio-organic enhancements.

Android 18 is a fit and beautiful woman of above-average height and fair complexion. She has shoulder-length blonde hair, although its specific shade varied between light/golden or platinum 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 when Future Trunks sliced parts of it off during his fight with her (in stark contrast to her future counterpart, who in the English dub threatened him for cutting off portions of her hair and claimed it could not grow back). She has a fairly small chest in the manga, while in the anime, her chest was implied to be large enough that Master Roshi after their plane crashed took the opportunity to plant his face in her bosom and smother his face within, leading to her nearly killing him. In the Androids Saga when she is first activated by Dr. Gero, she wears a blue denim vest and skirt (with the Red Ribbon logo on the back of the vest) with dark blue tights, a brown belt, brown boots, and a black shirt that has white and black striped long sleeves. After her clothes were ruined in her battle against Vegeta, she changes to a western-style outfit consisting of a brown armor vest and skirt with dark navy leggings, a blue-green long sleeve turtleneck shirt, and brown cowboy boots. Later when the androids arrive at Goku's House and throughout the Cell Saga, she wears a black mini vest with a golden triangle pin, a white short sleeved undershirt with a pearl necklace, dark teal jeans with a golden chain, a brown belt, a pair of short black gloves with a gold bracelet on the left one, and black flats with orange socks.

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.

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. She often expresses herself in her cool and downplayed manner, often smiling in a somewhat subdued fashion that conveys her very laid-back personality, However, 18's sense of humor is not always tactful.

Like her brother, she developed hatred towards Dr. Gero for modifying them against their will, though interestingly, she still uses the name No. 18 instead of her original name Lazuli and in the dub even refers to Dr. Gero as her father, albeit sarcastically (as he was the one who gave her the name No. 18) when asked about her name during the World Tournament. It was this shared hatred and distrust of Gero that convinced 18 that Cell was only imitating 17's voice to trick her. Though she lacks her future counterpart's sociopathic and murderous personality, she does share her counterpart's love of shopping and interest in fashion, as well as taking care in maintaining her appearance and dislikes having her clothing or hair damaged in battle. In the anime, she is shown to dislike Chi-Chi's Chinese dresses while trying her clothes when the Androids come to Goku's House looking for Goku. This is in contrast with her future counterpart who had no problem with the Chinese dresses she tried on while shopping for clothes during The History of Trunks special, showing that she and her counterpart apparently have different tastes in fashion.

Despite her reserved and abrasive personality, she shown on several occasions that she can be proactive to develop bonds with people who may not be friendly in return. However, she still at times retains some of her original cool and sarcastic nature.
