Bulla is a fictional character in the Dragon Ball franchise. She makes her debut in "Buu's Reincarnation", the 290th episode of Dragon Ball Z, which premiered on January 24, 1996. Like Bulma and Trunks, Bulla's name is an allusion to an undergarment, the bra in particular (this pun is more apparent in the Dragon Ball manga, where the character's name is literally spelled Bra).
Bulla is the second child of Vegeta and Bulma, and thus is both a Saiyan and human by blood. She is born 1 year after the defeat of Kid Buu. She is close friends with two other descendants of the Z Fighters, Marron, the daughter of Krillin and Android 18, and Pan, the daughter of Gohan and Videl. Of the three girls, Bulla is the most exertive of her femininity, especially in comparison to Pan, who by Dragon Ball GT has grown into somewhat of a tomboy. Bulla's appearance in Dragon Ball GT appears as a more youthful retooling of a common look of her mother's (most memorably during the adventure on Planet Namek, as well as the Androids Saga), while her personality is geared closer towards that of her father.
Bulla is usually cheerful, eager to please, and is very fond of her father. Her father doesn't appear to make a point of encouraging her to train as he does with her brother, Trunks, but the two are quite close. In fact, Bulla may be the only person Vegeta demonstrates not hesitating to answering to, often bending to her wishes such as insisting he shave off his mustache because she feels it doesn't suit him, or taking her to go shopping.
Bulla makes an appearance in the Dragon Ball video game spin-off Budokai Tenkaichi 2, wherein upon the completion of Basic Training, she appears and attests that she has come from the future, and says "I'll take shopping over training any day," and also says "I'm not sure if I understand but do your best." She does state that her "parents were so lame." She also makes an appearance as the character who describes missions in the GT saga of the video game, Infinite World.
