Bulma Briefs, a human scientist and inventor, begins her journey as a teenage girl hunting Dragon Balls to wish for an ideal boyfriend. Her fateful meeting with Goku in Mount Paozu sparks their quest to gather the mystical orbs, catalyzing the series’ overarching events. As heiress to Capsule Corporation founder Dr. Brief, she wields unparalleled technological prowess, pioneering inventions like the Dragon Radar for tracking Dragon Balls and DynoCaps for compact storage. Demonstrating genius early, she surpasses her father’s skills by age five, repairing alien spacecraft and crafting energy weapons as a child. In the Saiyan and Frieza sagas, she reverse-engineers Raditz’s scouter to gauge power levels and spearheads the mission to Planet Namek using a restored Namekian ship. Her innovations facilitate allies’ resurrection and Earth’s Dragon Ball restoration. Later, she devises a shutdown remote for Androids 17 and 18—destroyed before use, altering timelines. In a dystopian future, she builds a time machine for her son Trunks to avert Goku’s death and the Android apocalypse. Her rapport with Vegeta shifts from pragmatic coexistence to marriage, bearing Trunks and Bulla. While Vegeta maintains emotional distance, their bond tempers his aggression, with Bulma grounding his volatile nature. In *Dragon Ball Super: Super Hero*, she aids Piccolo and Gohan against the Red Ribbon Army, strategizing to summon Whis and later recruiting former foes Dr. Hedo and Gamma 1 into Capsule Corp. Bulma’s scientific feats span repairing Android 16, engineering the Super Dragon Radar to detect planet-scale orbs, and designing a Blutz Wave generator for Vegeta’s Super Saiyan 4 transformation in *Dragon Ball GT*. As Capsule Corp’s CEO, she equips the Z Fighters with battle armor, aircraft, and advanced tech. Marked by vanity, pragmatism, and fierce loyalty, she evolves from a self-absorbed teen to a matriarch steering Earth’s defense. Her flair for fashion yields ever-changing hairstyles and outfits, often flaunting Capsule Corp logos. Though noncombatant, she outwits threats repeatedly until briefly consumed by Majin Buu. Later, she pivots to logistical support and diplomacy, negotiating with cosmic beings like Beerus and Whis to safeguard Earth. Her birthday celebration in *Battle of Gods* becomes a clash site, where challenging Beerus provokes Vegeta’s defiant outburst. Rooted in *Journey to the West*’s Tang Sanzang reimagined as a tech-driven unifier, Bulma anchors the franchise’s narrative framework, propelling pivotal plot turns through innovation and alliance-building.
