The Big Tree Cannon (ビッグ 木砲, Biggu Kihō) is an energy wave attack used by Trunks Brief.


Trunks extends his arms to his sides and forms two golden energy spheres. He then brings his arms to his front and fires a large golden energy wave at his opponent, inflicting a high amount of damage.

It is likely that it was either taught to Trunks by Vegeta or that Trunks developed it after watching his father perform the Final Flash.


Dragon Ball Z

Trunks used this attack in his match against Son Goten at the 25th Tenkaichi Tournament. Later, Trunks (who was with Goten in a Mighty Mask disguise) used this attack again in an attempt to blast Artificial Human No. 18 out of the sky.


Trunks used this attack with Goten's Kamehameha to destroy the solidified Bio Broly in Dragon Ball Z: Bio-Broly, but the color was changed to blue.
