Launch is a heroine of the manga and anime Dragon Ball and one of the standard secondary heroes of the series. Launch suffers from advanced schizophrenia which causes her to shift between a soft-spoken kind-hearted personality and a brash borderline sociopath personality, for unknown reasons the personality switchs affect her hair color, with the kind-hearted Launch having black hair and the wild rogue having blonde hair. While kind Launch is certainly safer to have around she is a pacifist who can not bring herself to do harm to others, anarchist Launch though can and will annihilate anyone who tries to hurt Goku, Krillin or any other of her friends. Launch's brash personality is also a hardened criminal however her thefts are usually foiled by her kinder-side who returns the money, car etc., confused as to why she had them in the first place. Neither personality seems to acknowledge the other exists despite attempts to inform her of such.
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 tank top, yellow shorts with a red belt, brown fingerless gloves and red shoes with the Nike signia 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 82 cm, her waist measurement is 57 cm, and her hip measurement is 83 cm.
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 breasts, bottom, underwear, 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.
In her bad form, Launch has blonde hair and thin, green eyes. Goku, Master Roshi, and Krillin are all deeply afraid of her bad side after she shoots them all with a machine gun. Afterwards, all of them run behind a boulder several meters away in fear, after being victims of her first assault, when it seemed like she would sneeze, and carefully observing her during dinner, ready to run away at the first sign of a sneeze. Somehow, she always appears to have a machine gun on her. Her personality in her bad form is tough, arrogant and serious.
Her transformations come in handy during the 22nd and 23rd World Martial Arts Tournaments, when she would clear the crowd and allow her friends to get up in front. Additionally, in the later episodes of the series, she seems to be more in control of her blonde form, whereas her earlier transformations in the series turn her into a berserk maniac with no control and no memory of any of the gang. In fact, later on in the story, she begins to control her blonde form completely and this is confirmed when she is shown to care greatly for Goku and the others, and even cries after Krillin's death, though she is still more aggressive than her other half.
Launch's blonde counterpart was the highest wanted criminal in Brown Country. One day, after turning into her blonde self when sneezing in a bar, she robs a train, getting the police to chase her. During the chase, she accidentally sneezes, bringing her back to her weak and innocent form. Launch is saved by the young martial artists Goku and Krillin, while they are on Master Roshi's order to find him a woman. Goku and Krillin think the police officers are just impersonators, and Goku knocks them unconscious while Krillin hides. Launch is brought then to Kame House, where she is introduced to the turtle hermit Master Roshi. She agrees to stay with them so she can train with them and lay low from the authorities finding her. Roshi gives Launch some clothes which he calls a "fighting uniform", but is actually lingerie. Then, just as they are about to begin, a bee comes and tickles Launch's nose, making her sneeze into her bad side. She does not like what she is wearing, and angrily shoots Master Roshi, Krillin, and Goku. While she is shooting them, she then sneezes again and apologizes for shooting at them, and explains that she changes personalities whenever she sneezes.
Once they moved to the Training Island, Launch decides to just cook and clean the house instead, since she does not like fighting. Two days after recovering from the poorly prepared puffer fish, Krillin and Master Roshi sleep in the living room while Goku and Launch sleep together in the same bed. In her good side, she sneezes while in her sleep. One morning, Launch (in her bad side) finds Goku in the same bed as her, and shoots at him. Pushing him too far, Goku fights back and knocks Launch out with a kick to the face. Another time, Launch is eating dinner with the gang when Krillin begins to put pepper on his food, causing Launch to sneeze. She shoots at them, causing them to run away. Launch spends the next eight months cooking for Goku, Krillin and Roshi as they prepared for the 21st World Martial Arts Tournament while at the three try to avoid Launch's angry blonde side. Launch stays at the house while the three go to the tournament.

Soon, Launch's bad form comes out and takes command in Kame House, which then comes to an agreement to not shoot Roshi as long as he does what she says. One time, Master Roshi gives her some food, which tastes awful. She is about to shoot at him when Turtle, who came back from vacation recently, brings Launch back to her good form by rubbing her nose with a weed. After returning to her normal form, some Red Ribbon Army troops led by Captain Dark show up, demanding the Dragon Balls Goku had left behind. Roshi easily defeats them, but one threatens to shoot Launch if he does not give up. Turtle luckily turns Launch back to her bad form by once again by rubbing her nose with a weed, resulting in her beating the soldier herself. Later on, Launch joins Yamcha, Roshi, Bulma, Turtle and Krillin to go help Goku fight the Red Ribbon Army at their main base, but by the time they got there, all the troops were single handedly defeated by Goku.

While getting annoyed with him Launch tries shooting him with her machine gun, but Master Shen is able to catch all the bullets with his hand not hurting him. Next, Launch is able to get the crowd into the front row by shooting a gun up in the air, causing people to get scared and move.

However, after the match is over, she compliments both of their skills and joyously wants to go out to eat to celebrate.

She manages to blow up one of the chasing police cars with her Rocket Launcher and outruns the other one. Later, she joins Tien and Chiaotzu, who are training by a waterfall, and screams Tien's name, bringing him out of his concentration.
