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 anger and 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.
Appearances in Video Games
Big Tree Cannon was named in the Budokai Tenkaichi series, where it appears as Kid Trunks' Ultimate Blast in his Super Saiyan form. It is also Gotenks' Ultimate Blast in his base form and one of his Blast 2 attacks in his Super Saiyan and Super Saiyan 3 forms. In the Raging Blast series, Gotenks' usage in his base form has the attack's color changed to blue. It also appears in the Butōden series and Dragon Ball Z: Supersonic Warriors 2, named Kiai Ho and V Cannon respectively.
- The technique's Japanese name, Bikutorī Kyanon (ビクトリーキャノン), can be translated as either "Big Tree Cannon" or "Victory Cannon". The Bikutorī Kyanon translated as "Victory Cannon" is used for Gotenks' Mouth Energy Wave technique in the Budokai series.
- The name of the technique also plays a word joke with its user's name, Trunks and "Big Tree Cannon".
