Mario Finale

Mario Finale known in Japan as Mario Final (マリオファイナル, Mario Fainaru), is Mario's Final Smash in SSF2. Once released, Mario will launch a pair of spinning flames that grow larger and larger as it goes off screen dragging any opponent on its path. It can be a OHKO if performed correctly.

Trivia

 * Prior to version 0.5a of the SSF2 Demo, before Fire Mario got brawlified, when he fully charged a Super Fireball and released it, it would become a mini-version of the Mario Finale, and though not near as powerful as the new one, Fire Mario would not have to transform back into regular Mario.
 * In v0.8a, a bug gave the Mario Finale an advantage that it could be used as many times as the player wanted without reverting Fire Mario into his regular form, as long as it was used on the ground. However, it could only be used for racking-up damage and it would rarely drag the opponents off-screen. This bug could not be used if Fire Mario performs the attack in midair.
 * Mario Finale is one of the two special moves that are considered "Final Smashes within Final Smashes", the other being Genki Dama from Super Saiyan Goku. Both attacks are used by Final Forms and could only be used once per transformation as they drain the users' energy and revert them to their regular form. Mario Finale, however, requires manual charging while Genki Dama is charged automatically.
 * The sprite of the fireball is the Speed Burner from Mega Man X2.
 * In version 0.8b and 0.9a of the demo, Mario Finale can be cancelled by an opponent if he/she put up his/her shield when it hits. This makes the whole attack disassemble.
