Trunks, a Saiyan-Human hybrid and firstborn of Vegeta and Bulma, grew up under Bulma’s care in Age 766 while Vegeta’s attention emerged post-Cell Games, gradually strengthening their bond. Rigorous training from his father instilled a competitive, confident demeanor rooted in Saiyan pride. By age eight, Trunks unlocked Super Saiyan independently, stunning Vegeta during a gravity chamber session. In the Majin Buu arc, he competed in the 25th World Martial Arts Tournament, claiming the Junior Division title by defeating Goten—both bending rules with Super Saiyan forms. Later, disguised as "Mighty Mask" with Goten for the adult division, their ruse was foiled by Android 18. Confronting Majin Buu, Trunks joined pivotal battles, witnessing Vegeta’s self-destructive sacrifice and training alongside Goten under Goku to master the Fusion Dance, creating Gotenks. Though their fused Super Saiyan 3 form faltered against Buu due to overconfidence, it underscored their potential. His appearance evolved from a dark green gi with orange accents in childhood to casual attire like a yellow jacket and jeans in *Dragon Ball Super*. By *Super Hero*, he sported a taller frame, blue hair, a purple vest, black shirt, blue jeans, and red-outlined shoes. Personality-wise, he balanced Vegeta’s pride with Bulma’s assertiveness, demonstrating fierce loyalty to family—particularly protecting sister Bulla after initial disappointment at her birth. Inheriting Bulma’s technological knack, Trunks identified biotech gear in *Bio-Broly* yet prioritized martial arts over Capsule Corp duties. Non-canon films like *Broly - Second Coming* saw him clash with Broly’s clones, while Japanese versions highlighted playful antics, including taunts and irreverent gestures. In *Dragon Ball GT*, Trunks assumed a mature role, donning a black long-sleeved shirt, tan blazer, and brown boots. Partnered with Pan to retrieve the Black Star Dragon Balls, he wielded the Brave Sword until Baby’s possession briefly twisted his actions. Despite Pan’s provocations, he maintained patient composure. Contrasting his future self—raised in a war-torn timeline under Gohan’s guidance—the present Trunks’ peaceful upbringing forged his boldness. Future Trunks’ wariness, shaped by loss, highlighted environmental impacts on their psyches, though both shared tactical ingenuity against foes like Dr. Myuu and Baby. Trunks’ arsenal includes energy projection, flight, and fusion techniques. Attacks like Burning Attack and Galick Gun were sharpened under Vegeta’s tutelage. While he did not attain Super Saiyan 2 or 3 solo, Gotenks accessed higher forms and unique moves such as the Super Ghost Kamikaze Attack. Childhood admiration for Mai evolved into mutual affection, adding personal layers to his combat-driven life centered on family loyalty.
