Bulma

Bulma has a temperamental personality while being very tomboyish and girly at the same time. While known for her extreme intellect, Bulma is considerably spoiled and vain, using her great beauty as an excuse for her selfish behavior. Her selfishness prevented her from being able to ride the Flying Nimbus. While in stressful conditions, she becomes frightened easily and gets angry toward everyone including her allies. Bulma tends to have a great deal of concern over her hygiene, frequently complaining when circumstances prevent her from taking a bubble bath or replenishing her beauty supplies, even when her hygiene is the least of her worries such as being stranded in the wilderness.

Despite her temperament, Bulma often displays friendliness and helpfulness towards others. She tends to approach major situations rationally, often making crucial decisions on her own, and she tends to be very persistent in achieving her goals. As she gets more mature, Bulma focuses on becoming a great scientist and helps out by creating and fixing inventions that help the Dragon Team and her family. She is shown to be very witty, usually teasing her friends, a part of being happy and easy-going. In the Japanese version, she even refers to Goku and Krillin by the Japanese suffix "-Kun," indicating she is very close to them. Bulma enjoys strawberries,[8] attractive boys and bubble baths. While dealing in certain social dilemmas, Bulma would sometimes have to deal with using her sex appeal to get what she wants. Though she shows a strong dislike to perverted men, she herself got infatuated towards any attractive guy she saw even in her early adulthood, even during the time she was dating Yamcha, whom she claimed she was in love with and intended to marry. On a related note, regarding her being infatuated with any attractive guy she saw, sometimes her infatuation can cause her to flirt with a guy in a very crass manner, as demonstrated by when she encountered General Blue before learning his true sexual orientation where she grabbed his arm, licked it, and also meowed like a cat. However, she loses interest in him due to his lack of commitment to her and becomes more committed to her relationship with Vegeta. At times, she doesn't watch her mouth, which gets her into trouble. On a similar note, she also had a severe lack of tolerance towards Yamcha being approached by other women when she was still dating him, as she initially broke up with him when she thought Yamcha was cheating on her for Hasky, and when Maron attempted to flirt with Yamcha a second time, she stormed over to the two and proceeded to furiously scold Maron (though the latter bit ended up backfiring when Chi-Chi's timed arrival to scold Maron resulted in Maron expressing at amusement at the "two middle-aged ladies" [referring to Bulma and Chi-Chi] and caused the two to get into a furious argument over their ages).

Despite their rocky start and quarrelsome natures, Bulma tends to have a unanimous relationship with Vegeta, which increasingly improves after they get married. Bulma tends to take control over Vegeta and often berates him for his rude behavior, yet she takes pleasure in teasing him. Although they can argue often and despite him being a former enemy to the Z Fighters, Bulma is very devoted to Vegeta and truly loves him, even taking great pride at being his wife. After becoming a mother, Bulma is a very loving one towards her son and daughter, even though she demonstrated some irresponsibility when she took Trunks to the Androids battlefield when he was a baby, but she later learns from this mistake.

Bitter breakup and her marriage to Vegeta notwithstanding, Bulma and Yamcha still love each other dearly as childhood friends, enough so that the former unhesitantly wept in the latter's arms as he comforted her at the news of Vegeta's death battling Buu. By the time of Super, Bulma clearly still considers her ex an important part of her life to invite him to every one of her frequent celebrations, and happily lets him hold baby Bulla (though Vegeta was less than amused when the lovable oaf inadvertently made her cry).

One of Bulma's most interesting relationships is her friendship with Goku, having known the Saiyan for the majority of his life and becoming his first, and one of his closest, friends. Initially, she expressed frustration and annoyance towards his lack of hygiene, manners, and knowledge of the world and sought to only use him as protection whenever they encountered serious trouble when looking for the Dragon Balls. But soon, Bulma came to warm up to and care for Goku as a dear friend, their relationship being akin to that of an older sister-younger brother. As they grew up together, Bulma would assist Goku whenever he needed it and often showed great concerned for him whenever a task seemed too big or if he was in danger of being killed, though she would still get annoyed with his immature tendencies and forgetfulness and Goku has often shown to fear her temper to the point of being submissive and obedient to her. Even after they had both become adults, Bulma remained good friends with Goku even though she expressed irritation at him often being quick to fight someone and his habit of not taking things seriously enough. Despite this, Bulma's faith and trust in Goku whenever it came to combat has shown to be absolute to the point where she often displays more confidence in him than even her own husband, Vegeta, such as the battles with Majin Buu as well as Goku Black and Future Zamasu. Bulma's companionship with Goku also extends to his family, being a good friend of Chi-Chis and showing a great deal of warmness to his sons Gohan and Goten, even after the former grows up.

As she got older, Bulma was shown to have some irritation towards her fellow Z-Fighters for constantly relying on the Dragon Balls to revive people when dealing with a threat. This eventually came to a head when Piccolo, Goten, and Trunks were sealed inside the Hyperbolic Time Chamber when fighting Super Buu, where she called them out on their stating they'll revive Goten and Trunks with the Dragon Balls in case they get killed, especially when Goten and Trunks were children (also calling the rest of the Z-Fighters cowards in the Japanese dub), after Krillin suggested that Piccolo, Goten, and Trunks commit suicide and then revive them.

Though she is not a fighter, Bulma can be violent when angered and defend herself if need be. Several characters such as Krillin, Gohan, Goku and even to some extent Vegeta, are shown to fear her violent temper. When it seemed Frieza had been destroyed by the Large Spirit Bomb Krillin freaked when he remembered they had left Bulma all alone on Namek and Krillin even suggested that an angry Bulma is more terrifying than Frieza. Much later, Goku freaked out when he realized he had forgotten it was Bulma's birthday and even suggested she might be more terrifying than Beerus. Also, Vegeta adamantly refused to go training with Goku during Bulma's pregnancy because he feared she would never forgive him, although it's more likely that Vegeta wanted to be there for Bulma in this unsure time.

Even though she has noble qualities, she puts too high of an emphasis on her appearance, which is possibly one of the reasons why the Nimbus Cloud wouldn't allow her to ride on it. As she grew older, she became so paranoid about losing her good looks that she went so far as to collect the Dragon Balls simply to make herself look 5 years younger, as in Dragon Ball Super: Broly, she had already collected 6 out of 7 of the Dragon Balls. It's also implied that she'd done this a few times before.

She even angrily slapped the God of Destruction Beerus for ruining her party (however this was partially due to her belief that Beerus was a friend of her husband's). Fortunately, all Beerus did in response was to simply slap her right back, causing Vegeta to angrily attack Beerus in order to defend his wife. Over time, even Beerus came to fear her temper and often tries to avoid saying anything that will anger her. When she finally comes face-to-face with Frieza after his revival and confronts him along with the Dragon Team and Jaco, Bulma bravely confronts Frieza, to the point of even addressing the tyrant impolitely and rudely. However, her confidence and bravado were shown to due to her belief that Gohan and the other Z Fighters were stronger than Frieza and quickly lost her bravado (to the point she began speaking politely to Frieza) when Gohan and Piccolo pointed out that Frieza had become far stronger than he was previously. She even attempted to get Frieza to wait for Goku, but when Frieza agreed to wait only ten seconds for Goku to appear, she lost her temper and called him a stingy jerk (and in the Funimation dub even said "Screw you!" to Frieza and called him names, such as bastard and scumbag). On that note, in the Japanese version, she was shown to use very coarse language at times, with a very notable example of this being the aforementioned interaction with Frieza, where she demanded bluntly that Vegeta and Goku return to Earth immediately due to Frieza having returned from the dead, while describing him as being an "evil, rotten, [censored]ing asshole", with Frieza taking offense to the last part of the description (the Funimation dub tones this down to have Bulma refer to Frieza as an evil scumbag instead). Similarly, she also was shown to use rather rude and politically incorrect terms regarding specific people during her youth, which is best demonstrated with her first meeting with General Blue in the full-color manga. After the latter refused her advances in a manner that indicated he wasn't into girls at all, she proceeded to call him a fag (a slur used against homosexuals) in response (this was toned down in the VIZ translation to simply have her say "phooey, must be gay.")I
