Description
Trunks hails from an alternate future where Earth descended into apocalyptic ruin after Future Androids 17 and 18 were activated. These androids systematically exterminated most defenders, including Vegeta, Piccolo, and the Dragon Team, leaving Future Gohan as the sole survivor. Raised by his mother, Bulma, and trained under Gohan's mentorship, Trunks witnessed Gohan's death at the androids' hands. This tragedy triggered his transformation into a Super Saiyan, a pivotal moment in his development. He then became Earth's sole protector until journeying to the past in a time machine seeking a solution.

Physically, Trunks is a slim yet well-built young man with light skin and blue eyes. His hair color transitioned from lavender/purple in earlier appearances to a consistent blue in *Dragon Ball Super* media, including *Broly*. In *Broly*, he wears a light blue denim jacket featuring the Capsule Corporation logo, dark gray pants, and olive-green boots, contrasting with his Cell Saga battle attire resembling Vegeta's armor.

Personality-wise, Trunks exhibits seriousness, caution, and politeness, traits forged in his harsh, war-torn upbringing devoid of Vegeta's influence. Unlike his more arrogant present-timeline counterpart, he prioritizes pragmatism over Saiyan pride, often opting for decisive actions like eliminating threats swiftly (e.g., killing Frieza and King Cold without hesitation). He holds deep respect for his mentor Gohan and his mother, Bulma, and later demonstrates resilience against existential threats like Goku Black and Zamasu.

In *Dragon Ball Super: Broly*, Trunks appears briefly but significantly. He alerts Bulma that Frieza's soldiers stole six Dragon Balls from Capsule Corporation, initiating the plot to recover them. This leads Goku, Vegeta, Bulma, and Whis to the ice continent confrontation with Frieza and Broly. While not directly involved in the battle, Trunks is present during the Earth aftermath, underscoring his connection to his family and their protective efforts.

Trunks' history involves multiple timeline interventions. After defeating the androids and Cell in his future, he later returns to the main timeline seeking aid against Goku Black and Zamasu. During this conflict, he manifests the "Super Saiyan Rage" transformation and channels collective human energy into his sword—the Spirit Bomb Sword—to wound Fusion Zamasu. Ultimately, his timeline is erased by Future Zeno, leading him to relocate to a new timeline with Mai.

His familial relationships are central: he is the son of Vegeta and Bulma, the older brother of Bulla (Bra), and the nephew of Tarble. In his original timeline, Bulla was never born due to the androids' reign. His dynamic with Vegeta evolves from initial disdain to a mutual, albeit reserved, respect during the Goku Black conflict.
