Trunks starts the attack by extending his arms to both sides of himself and forms two golden energy spheres. Then, he brings his arms in front of him and holds out his hands with his index fingers pointed outward like a child pretending to use a gun, and fires a large golden energy wave at the opponent, inflicting a high amount of damage.
Trunks (who is with Goten in a Mighty Mask disguise) first uses the Big Tree Cannon in an attempt to blast Android 18 out of the sky during the final match of the 25th World Martial Arts Tournament, but to his dismay, she dodges it. He also uses the attack along with Goten's Kamehameha to attack the solidified Bio-Broly in the movie Dragon Ball Z: Bio-Broly, though in this usage, its color is changed to blue.
