After her activation by Dr. Gero, she appeared on skirt and blue vest, a black undershirt with black and white striped sleeves, brown boots and dark blue stockings. Thereafter, she wore black flats, black gloves with gold bracelet on the left one, a white undershirt, black vest and blue jeans.

The human names of Android 17 and Android 18 respectively are, “Lapis” and “Lazuli” which was coined from the name of a blue precious stone (Lapis Lazuli) that is valued for its deep blue color. However, she never revealed her birth name in the original Dragon Ball series, but after joining the Z Fighters and helping them defeat Super Perfect Cell, she was called “18”.
Android 18 possesses a humorous, confident and cool attitude, but the most visible of her characters is her strong sense of humor. Her sense of sarcasm was evident when Goku noticed her presence with the Z Fighters at the 25th World Martial Arts Tournament, which made her say, “Look, he noticed. How cute”. Also when she was being introduced by the World Martial Arts Tournament Announcer, she was asked if her legitimate name is “No 18”, she gave the funny reply, “My father was pretty dull”.
