Mario Finale

Mario Finale is Mario's Final Smash in Super Smash Bros. Battlers. It consists of Mario launching a powerful two-streamed blast of fire, which hits many times. It expands vertically as it moves away from Mario. As the blast moves away from him, opponeth the vortex are knocked slightly to the side, and are thus forced to travel with it

Each time a fireball hits an opponent, it does 3% or 2% damage, depending on whether it was the larger fireball or the smaller one.

Origin:
Mario Finale likely originates from Mario's attack "Ultra Flame" from Super Mario RPG: Legend of the Seven Stars. The attack involves Mario shooting a barrage of powerful fireballs that damage all the enemies on the screen. Mario Finale may also be inspired by Mario's long history of pyrokinesis (such as throwing fireballs, as well as his side smash being fire-based). Many fire-based attacks Mario had in the games he appeared are derived from his ability to shoot fireballs.

Trophy Description:
Mario with a Smash Ball, unleashing his ultimate attack. The twin dragons of flame he releases wallop all characters in range. The flames spread up and down, so it's best to release them from the edge of the screen at an appropriate height. His flaming eyes are proof of his excitement for this explosive attack.
