Bbbl, a Northern Mustafarian, belonged to the clan that was under the leadership of Father [Kkkt]. During 14 BBY, Bbbl participated in a scouting mission. Their objective was to investigate the location where a fiery object had crashed on the planet Mustafar. Despite an initial lack of findings upon arrival, Bbbl identified the Sith Lord Darth Vader, who used telekinesis to hurl a boulder. This caused the Mustafarian to fall into the lava.
On the planet Mustafar, Bbbl, a Northern Mustafarian, was a member of a Mustafarian clan that was being led by Father [Kkkt] during the Galactic Empire era. In 14 BBY, the clan observed a fiery object crash onto their world. Prompted by this, Kkkt dispatched a scouting party to investigate the crash site. This group included Bbbl, another Northern Mustafarian named Sssp, and two Southern Mustafarians, one of whom was Rrrn.

The group reached the supposed crash site, riding lava fleas, but found no wreckage. Sssp theorized that the object had likely disintegrated upon landing in one of the lava flows, and suggested they return to Kkkt with this information. At that moment, Bbbl used binoculars to spot a dark figure, who turned out to be the Sith Lord Darth Vader. Vader immediately used telekinesis to hurl a boulder at Bbbl, causing the Mustafarian to fall off their lava flea and into the lava of Mustafar. In the ensuing skirmish between Vader and the remaining members of the scouting party, only Rrrn managed to escape and report the incident to Kkkt.
Bbbl, like other Northern Mustafarians, wore armor along with a breath mask to protect themselves from the harsh environment of Mustafar. During the scouting mission, Bbbl was equipped with a Mustafarian blaster rifle and a pair of binoculars.
Bbbl's first appearance was in the twenty-second issue of the Star Wars: Darth Vader comic series. This issue was written by Charles Soule, illustrated by Giuseppe Camuncoli, and published by Marvel Comics on October 17, 2018.
