Mario Finale is Mario's Final Smash in SSBTUF. Mario launches 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.
Mario never used the Mario Finale in any Mario game, but it is inspired by the fact that Mario can use many fire-related moves in his games.
