Background / History

Bulma is the younger daughter of Dr. Brief and Mrs. Brief, and Tights's younger sister. She first meets Kasso at the family estate while he is asking her father to manufacture a Gravity Chamber. Seeing Kasso leap onto a roof more than ten meters above the ground astonishes both sisters 30.

Her scientific education advances far ahead of her age: she states that she had learned university-level material by five. She nevertheless continues attending school because she wants a complete life experience, rather than because she needs the coursework 122 138.

Appearance

• Childhood: Light blue hair, a round face, and a doll-like appearance; stands just over a meter tall, approximately Ausbie's height 30.
• Young adulthood: Described as beautiful, elegant, and refined when Kasso returns after eight years 75.
• Later appearance: Has a curvaceous figure and is shown wearing a white shirt during her first meeting with Chronoa 415.
• Spirit Fruit effect: Temporarily becomes muscular after consuming a Spirit Fruit 171.

Personality

Bulma is proud of her intelligence and quick to challenge anyone who doubts it. When Tights questions whether she can build Kasso's radar, she dismisses the concern and completes the device within half a day. She also makes her help serve a personal goal: securing flight lessons from Kasso 42.

Her training reveals persistence beneath her pampered upbringing. Although she eventually realizes that she does not enjoy cultivation itself, thoughts of Kasso keep her practicing for years. His recognition matters deeply to her; after learning to release energy, she says that she trained for so long to hear his praise 43 75 80.

She is outspoken with Kasso, scolding him and confronting him over his prolonged absences. Her assertiveness coexists with playful teasing and affection for her family, particularly Ausbie and Trunks 64 75 100 284 295.

Abilities & Skills

Scientific Genius

Bulma combines extensive theoretical knowledge with practical invention 42 122 190.

• Develops several possible radar designs as soon as she examines a Dragon Ball, including a backup approach if wave detection fails 42.
• Understands spacetime theory through her family's Hoi-Poi Capsule technology and immediately identifies problems in Philia's Time Machine prototype 190.
• Co-develops a working Time Machine with Philia; its energy ore is purchased from the Austin Chamber of Commerce 287 309.
• Recognizes Dr. Gero's scientific ability and reputation, judging his intelligence capable of rivaling her father's 192.

Dragon Ball Radar Construction

Bulma locates the distinctive waves emitted by Dragon Balls and builds a device that detects their positions 42.

• Completes her first documented radar in half a day for Kasso 42.
• Recreates the radar years later from her previous experience when beginning her own Dragon Ball search 75.
• Is considered a potential maker of a radar for the Super Dragon Balls, but is absent from that spacetime. Dr. Brief builds the completed Super Dragon Ball Radar instead 472 475.

Ki Manipulation and Flight

Kasso teaches Bulma to cultivate, control, and release ki 43 80.

• Creates a white energy sphere with one hand after a single day of energy-control instruction 80.
• Learns the Flight Technique after years of physical preparation 75 80.
• Demonstrates that sufficient combat power alone does not automatically confer flight: at 150 combat power, she still needs direct instruction 75.

Physical Strength and Combat

Bulma becomes capable of handling threats that would otherwise obstruct her travels 65 75.

• Lifts heavy machinery one-handed and captures robbers at approximately 30 combat power 65.
• Resolves numerous dangers during her Dragon Ball journey; Goku initially admits that her skills exceed his own 75.
• Sees through Pilaf's tricks, preventing the circumstances that would have led to Goku's Great Ape transformation at his castle 75.
• Has no interest in entering the 21st World Martial Arts Tournament despite her strength 75.

Equipment / Items

• Dragon Ball Radar — Her invention for tracking Dragon Balls; used by Kasso and later in her own search 42 75.
• Senzu Beans — Support her physical training. Kasso leaves her ten beans when departing Earth and later replenishes three that she has used; only one remains after years of training 45 65 75.
• Communication Bracelet — Receives Capsule Corp's report of a second Time Machine and projects its photograph for Trunks 220.
• Time Machine — Built jointly with Philia and used to visit Trunks's future timeline 286 287.
• Black card — Gives Kasso a card containing enough money to support Goku's family for several lifetimes; Kasso later passes it to Chi-Chi through Goku 148.

Relationships

• Kasso — Teacher, boyfriend, and eventually husband. Their relationship begins with an exchange of radar construction for ki lessons; his long absences frustrate her, but she remains attached to him 42 75 194 286.
• Tights — Older sister and fellow wife of Kasso. Bulma misses her during her extended travels and frequently teases her about her feelings for him 100 171 286.
• Dr. Brief — Father and scientist. He respects Kasso's training arrangements and later urges his daughters to spend more time with their mother 43 529.
• Mrs. Brief — Mother. Bulma's attachment to her parents makes the prospect of leaving their world with Kasso difficult 30 455.
• Ausbie / Little Biel — Close friend and fellow wife of Kasso. Bulma initially asks her for flight lessons and often hugs or clings to her 40 100 126 529.
• Philia — Scientific collaborator and fellow wife of Kasso. They build a Time Machine together 287 529.
• Goku / Son Wukong — Companion during her Dragon Ball search. He admires her early combat ability 75.
• Future Trunks — Son of her alternate-timeline counterpart. He calls her “Aunt Bulma,” while she develops a strong, almost maternal attachment to him 220 243 284 295.
• Future Bulma — Alternate self whom she affectionately addresses as an older sister. They bond warmly, and Bulma admires her achievement in building a Time Machine alone under apocalyptic conditions 286 287 295.
• Vegeta — Future Bulma's partner and Trunks's father, not Bulma's husband in Kasso's timeline. Bulma rejects the idea that she would fall for him; this timeline's Vegeta instead marries Launch 195 530.
