"Say hello to your doom, Cell!!"
First, Future Trunks throws his opponent up in the air and points both his hands up in the air. Then, he charges a large dome of yellow energy around himself. From this energy dome expels a gigantic Finish Buster up at the opponent, inflicting an enormous amount of damage.
Future Trunks uses this attack to destroy Future Cell in his imperfect form in his alternate timeline. Thanks to his training from the present timeline, Future Trunks easily outclasses Future Cell and knocks the Android down into the ground. When Future Cell attempts to attack with his tail, Future Trunks catches it and throws Future Cell up into the air. Future Cell then prepares a Kamehameha in hopes of defeating Future Trunks, but Future Trunks counters and destroys Future Cell with the Heat Dome Attack before he could fire his Kamehameha, declaring that the nightmare is over. With the Androids defeated and peace finally restored in his timeline, Future Trunks thanks Goku and the others for everything they have done for him. Future Trunks also uses this attack to destroy Future Dabura and Future Babidi to prevent them from awakening Future Majin Buu.
Appearances in gamesEdit
Heat Dome Attack is named in the Budokai Tenkaichi series, where it appears as Super Saiyan Future Trunks' (without sword) Ultimate Blast. It also appears in Dragon Ball Z: The Legend, Dragon Ball Z: Burst Limit, the Raging Blast series, Dragon Ball Z: Ultimate Tenkaichi, Dragon Ball: Tap Battle, Dragon Ball Z: Battle of Z, and Dragon Ball Z: Dokkan Battle.
It is also used by Future Trunks in Dragon Ball Z: Shin Budokai - Another Road, Dragon Ball: Zenkai Battle Royale, and the Japanese arcade game Dragon Ball Heroes. In Dragon Ball Heroes, the attack can be combined with two Kamehamehas from Goku and a player avatar; the combined attack is so powerful that it blasts the opponent into space. Additionally, as a Super Saiyan 3, Future Trunks uses the attack against Majin Buu in the second promotional video for Dragon Ball Heroes. In Dragon Ball: Xenoverse, it appears as Future Trunks and Xeno Trunks' Ultimate Skill. It can also be obtained by the Future Warrior as a reward in Parallel Quest 26: "Warriors' Annihilation - Future Chapters". Super Saiyan Trunks' equipable Z-Soul, "Vanish forever!" (based on his final words to Future Cell) increases the power of the Heat Dome Attack and all stats temporarily increase when the Heat Dome Attack is used. This Z-Soul mistakenly refers to the technique as both Destruction Bomb and Heat Dome in its in-game description.
