Bron Dooku, formally addressed as His Grace, Bron Dooku, Count of Serenno, was a Human male individual affiliated with House Dooku. He was the offspring of Adan and Maite Dooku, and also the grand-nephew of the notorious Count Dooku.
Around 13 BBY, Bron Dooku's birth occurred within House Dooku, a powerful and influential house situated on the planet of Serenno. His parents were Count Adan Dooku and his wife, Maite Dooku. His mother eventually passed away, leaving Adan to be the sole caregiver for Bron. During his father's time in power, Bron routinely accompanied Adan on journeys aboard their family airship, the Windrunner. His father instructed him in politics and the importance of realistic and pragmatic thinking as part of his preparation to inherit the title of Count.
In 3 BBY, Bron was present on Alderaan to commemorate the twenty-fifth anniversary of the Alderaan Ascendancy Contention. He encountered Leia Organa at the reception and expressed his admiration for her beauty.
Later that night, he was in his bedroom, part of the suite he shared with his father, when he was disturbed by the loud argument taking place between his father and Bail Prestor Organa. Upon leaving his room to investigate the source of the noise, he witnessed Jahan Cross, an Imperial assassin, shooting and killing his father. Organa swiftly pulled Bron to safety as security forces began their pursuit of the killer of Bron's father.
After his father's passing, Bron accompanied the other House Lords on the Windrunner to determine his future. He then encountered Jahan Cross, who he recognized as the son of Ambassador Cross. During the Bloodskull's attack, Aveca Dunn kidnapped Bron, but Cross rescued him. Bron was then brought to Otoh Dooku, where Hovus Jorrick, Borgin's security chief, and his guards watched him until Cross and Candra Tymon arrived to take him. Jorrick's guard and Boba Fett pursued them until Fett launched a missile at his shuttle, seemingly resulting in Bron's death.
However, Bron had actually been transported to Alderaan to be raised by Bail Organa until he was ready to claim his title and position as Serenno's regent, should he choose to do so.
Throughout Star Wars: Agent of the Empire—Hard Targets, Bron Dooku's eyes were depicted as blue. However, the cover of Agent of the Empire – Hard Targets 5 showed them as brown.
