Mario Finale 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, opponents that come in contact with the vortex are knocked slightly to the side, and are thus forced to travel with it. Opponents that are in the center of the vortex are more easily trapped by it. The Dojo!! suggests to move to one side of the level and use it while in mid-air. Mario recoils slightly when he does the attack, but he is unaffected by gravity until the move ends, so it is mostly insignificant. If opponents are behind Mario, they will still be pulled into the attack.
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. The move is capable of hitting about 7.5 times a second, although this is unlikely due to the speed the fireballs spin at and the knockback delivered. Despite being a powerful Final Smash, it has one major flaw: if the opponents are far away from Mario, they can avoid the attack by jumping over it (especially high jumpers such as Fox or Yoshi). However, it makes up for it by inflicting damage on a wide range of multiple enemies and pushing them back quite some distance without allowing recovery, possibly even dragging opponents off the side.
The maximum distance of the Mario Finale reaches approximately from the edge of Final Destination to the spot right before the blast line. Since opponents are dragged along the length of the attack, it is best to not initiate from the end of a stage.
In Super Smash Bros. 4, the move has gained a new graphical effect with more "accentuated" fire. It also deals more damage and dramatically slows down opponents now, making it much harder to dodge the attack, especially at close range. However, it is harder to pull opponents into the rest of the Final Smash if they are behind Mario.
In Super Smash Bros. Ultimate, the move slows down opponents more, and for longer, at the beginning of the attack. However, it has substantially decreased knockback, which makes it KO foes around 25% later and worsens it overall. To nullify this, the range and damage (each hit doing 0.5% more) of the move was buffed in a patch, making it significantly more powerful and take stocks a bit earlier overall.
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.
Break the Smash Ball and unleash Mario's Final Smash. Mario will fire a devastating blast of fire in the direction he's facing. The attack covers a wide range and travels far, so it's best to fire this from one side of the stage to the other. The damage is impressive, and it can actually carry foes right off the screen!
When Mario gets his hands on a Smash Ball, he can activate this Final Smash. Flames spiral outwards in two intertwining stream, catching opponents in the wide blast with ease. It deals plenty of damage, and can also push foes off the screen entirely. Fire it from an elevated position to take full advantage of its vertical range!
Mario Finale vaguely resembles the attack Ultra Flame from Super Mario RPG: Legend of the Seven Stars. The attack involves Mario shooting a barrage of swirling, powerful fireballs that damage all the enemies on the screen. The move otherwise has no clear origin but rather takes inspiration from Mario's pyrokinetic abilities.
