Battle of Gods Arc
Bulma, Trunks, and Vegeta go on a family trip and are in route to an island far from home. Vegeta — perched atop their plane — laments that he isn't training, which causes Bulma to send their plane into a series of dives in order to "train" him. After a variety of maneuvers, which consist of diving into the ocean and flying the plane though a dense forest, Bulma is surprised that Vegeta is still unmoved. As the family relaxes in a gift shop, Bulma notes that Vegeta has changed positively: having given up his precious training to spend time with his family. Vegeta shrugs her remarks off, stating that he was merely keeping a promise he made to Trunks.
The family stops to eat, which Bulma notices calms Vegeta greatly. However, while they are eating an octopus, Vegeta gets sprayed with ink. Angered, Vegeta begins to power up, which shatters nearby glass. Bulma and Trunks quickly whisk him away to prevent more damage from being done. That evening, the family find themselves on the beach. Trunks spots a cruise ship crossing the bay and Bulma mentions that she could rent one to have her birthday party on. That night, the family attends a beach party. Bulma and Trunks search the crowd for Vegeta, but only to watch the angered Saiyan fly away.
Bulma decides to have her birthday party on a luxurious cruise ship and invites all her friends to the party. During the birthday party, the argument between Majin Buu and Beerus turns in a fight with the Z-fighters. Beerus effortlessly defeats the Z-fighters. Just as Beerus is about to finish Vegeta, Bulma walks up and slaps him for ruining her party. Beerus retaliates in similar fashion. Seeing Bulma get struck infuriates Vegeta; he explodes and powers up immensely.
After Goku becomes a Super Saiyan God and starts fighting Beerus, Bulma decides to follow them and takes a Capsule Corporation ship. In the ship, Bulma along with the Z-fighters watch Goku and Beerus fight. During the clash between Goku and Beerus, the ship's engine is damaged, making it difficult for Bulma and the Z-fighters to catch up with Goku and Beerus. Bulma tries fixing the ship's engine in order for it to fly faster, becoming steadily annoyed by the numerous requests for Bulma to fly faster. The ship reaches the island where Goku and Beerus continue battling.
After Goku and Beerus take their battle into Earth's atmosphere, Bulma flies the ship to the atmosphere. However, the power emanating from Goku and Beerus causes the ship to start malfunctioning.

Bulma's ship breaks down due to the shockwaves and begins plummeting towards the cruise ship. The ship is about to hit the cruise ship, but Whis uses telekinesis to stop the ship from crashing down and lands it safely on the water near the cruise ship.
After Goku is defeated and Beerus suddenly falling asleep, Whis informs a flabbergasted Z-fighters that the Hakaishin is tired, and explains that while Beerus won't wake up in a good mood, he'll likely forget about the destruction of Earth. Whis also informs the Z-fighters to make sure they have pudding the next time he and Beerus arrive, to which Bulma assures, but demands that the Earth will not be destroyed if Beerus does not like the pudding. Whis responds that Beerus will be quite angry if he does not like it regardless, which annoys Bulma.

Sixth Universe Arc
When Goku and Vegeta return to Earth with the news of the Super Dragon Balls, Bulma is initially surprised. The two, along with Whis and Beerus, want to know if Bulma can make a Dragon Radar that can detect the presence of these larger wish orbs. Bulma decides that, if the Super Dragon Balls are the same as the normal Dragon Balls, only larger, she should be able to make a radar that can find them by increasing the sensitivity of it. She comes up with a simpler idea, however: collecting Earth's Dragon Balls and summoning Earth's Shenron to wish for the location of the Super Dragon Balls. Beerus commends her for the idea, seeing her as more than a middle aged woman; on reflex, Bulma slaps Beerus, but is forgiven due to her idea. As Beerus orders Vegeta to go find the Dragon Balls, Bulma watches her terrified husband fly off in amazement.
After Vegeta comes back with the Dragon Balls in tow, Bulma is the one who summons the dragon forth. While Beerus says Vegeta gets the job done quickly as his errand boy, Bulma reproaches the Hakaishin for this, and commends Vegeta for his hard work, rewarding him with a kiss on the cheek. As Shenron is summoned, Bulma steps up to ask Shenron for the location of the final Super Dragon Ball. However, she realizes things won't be this simple as the wish is beyond Shenron's powers. Because of this, she decides to go with the original plan to make the Super Dragon Radar. When Goku realizes he forget to wish the North Kaiō back to life, Bulma simply tells him to forget it.
Later that night, Bulma treats Goku, Vegeta, Beerus, and Whis to a feast of beef stew. When Beerus reprimands Goku by shouting, Vegeta covered Bulma's ears to prevent damage. She also takes note that Champa could have either wished for food, or the duplication of Earth, if the Super Dragon Balls can grant any wish. Beerus however, simply states the Dragon Balls are the excuse that the Hakaishin need to fight. The next morning after Beerus' departure, Bulma is awake and hard at work creating the Super Dragon Radar. She remembers vividly the expression Beerus had before he left, worried about the wishes he'll make. Distrusting Beerus, and wanting to collect the seven Dragon Balls before him, Bulma contacts her sister,Tights, to bring Jaco to Earth. When Jaco is initially resistant, Bulma threatens to send Vegeta to attack Galactic Patrol headquarters, forcing him to agree. When Goku tests out the radar only to find no response, Bulma explains that Earth is at the edge of the Universe, and to find the Dragon Balls, they'll need to spread out to the center of the Universe to find them, determined to not let Beerus have his way.
