Brave Cannon is an energy sphere technique used by Trunks in Dragon Ball GT, and Tapion in video games. First, the user puts his two arms on his right side and charges a large, powerful ball of ki. Then, he throws the ball at his opponent, causing an explosion which inflicts a large amount of damage.
Trunks first used it on Planet Luud to destroy the tiles Mutchie was throwing at him and Goku. He later used it to kill Mutchie while he was absorbing Goku's energy. It is very similar to the Finish Buster used by Future Trunks.
