Future Bulma

Future Bulma is the alternate timeline counterpart of Bulma that appeared in Dragon Ball Z TV Special 2, and the very end of the Cell Games arc. She is the widowed mother of Future Trunks. Besides her son, she was the last surviving member of the Z Fighters in her respective timeline. She played a small and largely unseen very important role in the Trunks arc all the way through the Perfect Cell arc, creating the Time Machine that made Future Trunks go back in time in the first place, and warn everyone about the Androids. Future Bulma returns in Dragon Ball Super, but is kill by Black Goku when her son tries to go back to the past in order to get help.

Background
Up until the Trunks Saga, Future Bulma's biography was exactly the same as that of her mainstream present counterpart, Bulma. In August of Age 764, she watches Future Son Goku traveling back to Earth via his Instant Transmission technique and kills both Future Frieza, and Future King Cold.

Two years later however, Future Bulma is seen outside the Sons' house as Future Goku sadly dies from a incurable heart virus which didn't have a cure, while holding the six month old Future Trunks in her arms. Six months follow Goku's tragic death, two killer androids attack on May, 12 Age 767. All of the Z Fighters except for Future Son Gohan are murdered by the robotic killing machines, and thus a new apocalyptic age dawns on the planet Earth.

Thirteen years later, after Gohan is killed, Bulma devised a plan to defeat the Androids that are attacking their world: She would send her son back in time and solicit Past Goku's help in defeating the Androids, since he never even got a chance to fight them at all in her time. It took some convincing, but Future Trunks eventually agreed, but for his own reasons (whereas Future Bulma merely wanted the satisfaction of knowing that at least one timeline was saved, Trunks intended to find a weak spot in the Androids, so that he may not be able to revive those already dead, he could at least save those still alive). Finally, four years later in Age 784, the time machine would be completed, and Trunks would make his voyage into the past.

Personality
Due to the apocalyptic world that she raised her son in, she seemed much more loving, caring and serious than her mainstream counterpart, who was happy and easy going. Like Future Gohan, she too enjoyed the peaceful times as she chose to relax and continue working on her time machine even in times of crisis. She was easily the wiser of the two remaining Z Fighters, attempting to convince Future Trunks to not attack the Androids head on, and instead use the time machine. Because even though he was a Super Saiyan, but so was Gohan, and he failed.

However, following the Androids defeat, aspects of her old personality resurfaced, such as her teasing her son about having a new girlfriend when he abruptly requests that she go inside due to him sensing Future Cell nearby, Despite this, she stops upon realizing the seriousness of the situation, complying with Trunks' request, showing that the peace following the Android defeat has not dulled her ability to handle herself in dangerous situations.

In Dragon Ball Super, she still retains her serious demeanor. She tells Trunks that no matter what happens to her, he must travel into the past and enlist the aid of Goku and the others. Moments before her death by the hands of Black Goku, she still tells him not to worry about her and go on, showcasing both her determination and willingness to die if it means saving their timeline.

Appearance
Future Bulma appears exactly like her counterpart, by having long hair. But she seems to wear different clothes every now or then. In a flashback by her son, while he describes how his timeline is to the Z Fighters, Future Bulma is seen with her hair in a bun, but has cures coming out of it. In the manga, she is seen smoking a cigarette, but this is edited out in the anime. Once her son comes back from helping Goku out during the Cell Games arc, just like her counterpart. Future Bulma is seen with long hair again, but after her son finally kills Future 17 and 18, She is shown to have cut her hair short, just like her counterpart.

Anime Filler
Later, when Future Trunks returned from the past, Bulma was both astonished, and not astonished at the fact that Goku died anyway by sacrificing himself to save the planet (her exact words were "That sounds just like Goku"). She was completely astonished at how Vegeta had defended her son when he died. Later, when the Androids were on the move again, Future Trunks went to fight, and this time, she believed in him, and merely asked him to be careful.

Finally, as Trunks was preparing to go back in time once again to tell his friends that he managed to beat the Androids. But Future Cell in his first form attempts to steal his time machine. Future Bulma is seen teasing Trunks about a new girlfriend, but quickly goes inside when she sees how serious her son is. Future Bulma is seen looking out of the window at her son about to battle Future Cell. In the manga, she is lastly seen happily running to her son to hug him after he comes back from the battle with Future Cell.

Future Trunks arc
In the Extra Edition 1 of the manga, Future Bulma's past during the conflict between the Future Z Fighters and Androids is shown. She ends up detecting someone has gathered the Dragon Balls and races to the battlefield in her airplane with baby Trunks in tow, picking up Future Gohan as he was leaving to search for the Dragon Balls before Future Piccolo died. She informs them someone has gathered the Dragon Balls, and they race to stop them as they need the wish for Future Gohan's plan to use them. Unfortunately, they arrive too late and find the Future Pilaf Gang have been turned into infants including Future Mai who notices Trunks. As the Dragon Balls fall to the ground as stone instead of scattering across the Earth, she and Future Gohan realize that Future Piccolo has been killed.

Seventeen years in the future, a man named Black Goku goes on a rampage and causes the humans to verge on the brink of extinction. He is encountered by her son, Trunks, but he fails in defeating him. Bulma suggests to Trunks that they should receive help from Goku and Vegeta in the past. In the matter of six months, Bulma managed to gather enough fuel for a two-way trip to the past for the Time Machine. However Black Goku attacks the lab, destroys some of the fuel and kills Future Bulma in front of Future Trunks, vaporizing her with a point blank range Ki blast to her face. Her soul was destroyed when Future Zen-Oh erased the timeline to kill Zamasu. However, she is still alive in the timeline created by Whis where Zamasu would be stopped by Future Beerus.

Trivia

 * In the manga, she smokes a cigarette. However this is edited out in the anime.
 * Future Bulma's invention of the Time Machine is the second time an invention of Bulma's has unintentionally endangered both the Earth, and the universe due to it violating the natural order of the universe, despite her noble intentions. The first technically speaking was the Dragon Radar which allowed the Dragon Balls to be overused and become overloaded with negative energy giving raise to Black Smoke Shenron and the Shadow Dragons in Dragon Ball GT. Fortunately, due to Kami's death the Dragon Balls of her timeline were rendered inert, averting their potential overuse giving rise to the Shadow Dragons in Future Bulma's timeline.
 * In DBZ Xenoverse, it is mentioned that she is running the day to day operations at Capsule Corporation, and is supplying Toki Toki City with her inventions. In Xenoverse 2, it is also implied by Whis that the Future Bulma's company provides ingredients and dishes from Earth for Conton City as well in addition to other products. It is also implied in the series that Chronoa is one of their company's big customers as she likes to order the latest technology due to her own fascination with technology.
 * However, she is not the only incarnation of Bulma to assist the Time Patrol as her Dragon Ball Super main timeline counterpart visits Conton City in Xenoverse 2 and constructs the Hero Colosseum using data she collected during her first visit to the city.
