Eis Shenron shoots the energy blast by turning his hand into a modern blasting cannon, with the Dragon Ball inside his arm emitting the ki. In the Japanese version, he says "Fire" as he shoots the blast, but in the English dub, he merely shouts "Hold this for me".
Appearances in games
In Dragon Ball: Xenoverse, it appears under the name Ice Cannon and is Eis Shenron's Ultimate Skill. It can also be obtained by the Future Warrior as a reward in DLC Parallel Quest Event: "The Shadow Dragons" which is part of the GT Pack 2 DLC. In the game, the user performs a quick spin before charging an icy cold ki blast to freeze whoever it hits. When performed by the Future Warrior, it is fired from the Warrior's left palm due to the lack of Eis Shenron's arm cannon.
