Mario Finale

Mario Finale, known in Japan as Mario Final, is 's Final Smash in Super Smash Flash 2.

Overview
When performed, Mario creates fire in his hands before launching two fireballs that travel forward. They spin around each other as they travel and quickly grow in size before reaching their massive maximum size. Opponents caught in the fireballs are dealt multiple hits of 3% flame damage each with weak knockback that drags them along their path. If performed at the correct time and direction, it may end up dragging opponents toward the blast line.

Origin
Mario Finale resembles the Ultra Flame attack 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. Aside from this, the move has no clear origin, but rather takes inspiration from Mario's pyrokinetic abilities he obtains after collecting a Fire Flower.

Trivia

 * The move was originally a part of Fire Mario's moveset, where it could be used after fully charging his neutral special move, Super Fireball. However, Fire Mario was completely replaced by Mario Finale in v0.9b of the demo.
 * Mario Finale was one of the two special moves that were 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, required manual charging while Genki Dama is charged automatically.
 * Prior to v0.5a of the demo, when Fire Mario fully charged a Super Fireball and released it, it would become a much smaller version of Mario Finale. Though it was not nearly as powerful as the new one, Fire Mario would not have to transform back into regular Mario.
 * In v0.8a, a bug gave Mario Finale an advantage in 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 performed the attack in midair.
 * In v0.8b and v0.9a of the demo, Mario Finale could be cancelled if an opponent shielded the attack. This makes the whole attack disassemble.
 * Prior to Beta 1.2, the sprite of the rotating fireballs was that of the Speed Burner from Mega Man X2.
 * the sprite of this Final Smash from v0.8 is used in v0.9b
