This is the picture of Son Goku Genki Dama, a martial arts discipline that allows the user to borrow energy from grass and trees, from people and animals, from inanimate objects and the atmosphere. Genki Dama also known as Spirit Bomb, widely considered to be the strongest attack in the series, but depends on the number of organisms supporting its use.
