Big Tree Cannon

Trunks extends both arms outward to his sides, gathering energy into two separate spheres in each hand. This wide charging stance closely resembles the way Vegeta prepares his Final Flash, reflecting Trunks' Saiyan lineage and fighting instincts. He then snaps his arms together in front of his body, points both index fingers outward, and releases a concentrated golden energy wave. The firing pose resembles a child mimicking a finger gun, giving the technique a distinctly playful quality despite its destructive power.

Trunks first fires the Big Tree Cannon during the 25th World Martial Arts Tournament while disguised as Mighty Mask alongside Goten. Stacked on Goten's shoulders under a single costume, Trunks uses the technique in an attempt to blast Android 18 out of the ring during their final match. Despite the power behind the attack, 18 dodges it cleanly.

Film Usage

In the Dragon Ball Z film Bio-Broly, Trunks combines his Big Tree Cannon with Goten's Kamehameha to create a joint energy wave against the titular villain. In this appearance, the beam's color shifts to blue rather than its typical gold.

Gotenks, the fusion of Trunks and Goten, has access to techniques influenced by the Big Tree Cannon, including the Revenge Cannon mouth blast. The technique appears throughout the Budokai Tenkaichi series, Supersonic Warriors 2, and Xenoverse titles as one of kid Trunks' signature special moves. Its visual connection to Vegeta's Final Flash through the wide-arm charging pose reinforces the father-son parallel that runs through the Vegeta family's fighting style.
