Final Blaster

Final Blaster (, Final Blaster) is 's Final Smash in Super Smash Bros. Ultimate.

Overview
Kazuya, in Devil Kazuya form, fires a beam in front of himself. Should this initial beam make contact with an opponent, a cutscene will show up where Kazuya is in a hellish dimension while saying ("This will be your burial ground!"), and after the cutscene ends, several beams in a wide pattern will be launched in front of himself, which eventually converge into a final wide blast and launch any opponents hit. If it the initial beam misses, the move will fail.

Origin
Final Blaster first appeared in Tekken 7 as Kazuya's Rage Art during the final battle in story mode with his father Heihachi Mishima. The form he takes on is also based on the new Devil form he uses after being irritated over Heihachi's tenacity and ability to weather his attacks. The background change is based on the volcano stage Brimstone & Fire, a backdrop Heihachi personally chose for their fight.

Kazuya later uses a variant of the same move against guest character Shin Akuma from the series, who serves as a bonus boss fight after the main story mode.

Trivia

 * The model for Devil Kazuya used in the Final Smash is different from the model used in all other situations. This model is based on Devil Kazuya's appearance in the story mode of Tekken 7, which is more detailed and scaly than normal.
 * Final Blaster is the fifth Final Smash to pause the music during the move, the others being Konga Beat, Waddle Dee Army, Peach Blossom, and Daisy Blossom. Unlike those however, the music is not replaced by another jingle and is simply muted. However, it is hard to tell due to the sound effects and Kazuya yelling.
 * If voices and sound effects are set to 0 in the Settings, the music will not pause.
 * Despite his reveal trailer featuring subtitles during Final Blaster, subtitles do not appear ingame while using the move.
 * Burning Sword, Sacred Arrow, and Final Blaster are the only Final Smashes that start off with a cinematic but end in-game. The opposite holds true for Infernal Climax.
 * Along with, these are also the only Final Smashes from DLC characters in Ultimate to contain non-cinematic elements.
 * Masahiro Sakurai showed an early version of Final Blaster in a YouTube video and showcased several changes made before the final version:
 * The story mode for Tekken 7 was used to inspire Final Blaster almost 1 to 1.
 * Kazuya's wings during Final Blaster were initially too rounded and Sakurai suggested they be made more angular.
