Galaxy Gun (ギャリック砲, Gyarikku Hou,) is one of Ryun's signature moves, a beam similar to Kamehameha and Galick Gun. It is capable of destroying large planets if enough power is put into it.
To utilize it, Ryun curls his fingers and places both his hands together at chest level facing the same direction (so that the palm of one hand is on the back of the other exactly like Vegeta's Galick Gun) and then, once enough ki is gathered, he thrusts both hands forward to fire a powerful blast of energy. The result is a concentrated, red-colored energy beam that emanates from his hands and body, moving with speed. The blast can also be used with just one arm.
The potent Galaxy Gun has several different colors. The power of the different types of Galaxy Gun also varies widely. Redish-purple is its standard and original color. When Ryun is in his Super Saiyan 4 and 5 transformations, his Galaxy Gun is crimson-colored. The attack was invented by Ryun over a two month period spanning the time just before his fight with Haifeiru. By drawing his latent ki into the palms of his hands, Ryun was able to expel an explosive beam of chakra.
- Super Galaxy Gun: is a full-powered Galaxy Gun capable of destroying whole planets if charged, and weakening their foundations and causing enormous destruction even when it's uncharged. It was performed by Ryun while in the Great Ape and Golden Great state and may have only been able to be performed by those transformations, as Ryun himself never used the move.
