*Launch is a woman with a strange disorder which causes her to switch between two different personalities each time she sneezes. Her first personality is a blue-haired woman, who is sweet, pure-hearted and cheerful and always ready to help. Her other personality is a blonde-haired woman, who is angry and trigger-happy and commits crimes for money and is quick to respond with gunfire when angered. Neither of Launch's personalities remembers the other's actions or anything they said, that is until the King Piccolo arc, which is evident when she remembers who Krillin was when he died.

Launch's outfits change often, but almost all include a red ribbon in her hair. Launch's initial appearance consisted of a light-green belly-baring crop tank top, yellow shorts with a red belt, brown fingerless gloves and red shoes with the Nike insignia worn with green socks. Launch's primary appearance changes during the General Blue Saga to a pink tank top and a black pair of pants with white knee pads. In the 22nd World Martial Arts Tournament, she wore a black shirt with green pants. In the King Piccolo Saga, she wore a purple sleeveless top with gray pants, a brown belt, and a brown sash. During the 23rd World Martial Arts Tournament, she wears a red dress with pink boots. Her bust measurement is 82cm, her waist measurement is 57cm, and her hip measurement is 83cm.

This version of Launch has blue hair and big, blue eyes. The innocent persona of Launch is pure of heart as she is quite capable of riding the Flying Nimbus with Goku in the anime. Her personality in her good form is similar to Bulma.

Launch is happy to carry out her work for Master Roshi, never realizing that he is constantly trying to grab, poke, rub, or catch a glimpse of her butt, breasts, panties, or bra. However, many of his schemes are foiled, if not by his own mistakes. When Launch's nose gets tickled and she sneezes, it causes her to change into her violent half. Launch has a very sensitive nose that, when irritated by even the smallest things, can result in a sneeze. Her sneezes are often provoked by things such as pollen, pepper, dust, and other common irritants.*
