Trunks' moves in Dragonball Z. It is a scaled down version of Vegeta's Final Flash. It is therefore safe to assume that either it was taught to him by Vegeta or he developed it after watchin his father preform Final Flash. The user starts by extending both arms to either side of himself, where two golden energy balls are formed, then the arms are brought forward to meet in front, where a large golden energy beam is fired at the opponent. Trunks uses this attack along with Goten's Kamehameha to destroy the solidified Bio-Broly in the movie Bio-Broly. It is also used by Gotenks in Budokai Tenkaichi 2 and 3.
