Goten used this attack during his match against Trunks in the 25th World Martial Arts Tournament. However, Trunks and the announcer dodged the attack, which then blasted a hole through the World Tournament waiting room.
The attack appears in multiple video games, such as Dragon Ball Z: Buu's Fury, the Budokai Tenkaichi series, and the Raging Blast series. It functions just like the regular Kamehameha, except in Dragon Ball Z: Legendary Super Warriors where it deals 25% more in damage while only being able to be used by Goten.
Naturon Shenron also uses the Kamekameha, but his version is just a mispronunciation, not uncontrolled like Goten's.
