Mario Tornado

Star Spin, known in Japan as Star-Shaped Rotation (回転星型, Kaiten Hoshigata), formerly the Mario Tornado (マリオトルネード Mario Torunēdo), is 's down special move in Super Smash Flash 2. It first appeared in Super Smash Flash as 's down aerial attack and used it in the SSF2 Demo since the first v0.1a up until v0.4a where it got a homing kick but couldn't be used as a recovery move. In both games, Mario and Luigi spin around rapidly for a short time, they end the attack by punching upward, knocking away trapped opponents.

In Super Smash Flash, the move is slightly quicker than the Super Smash Bros. Melee version. In Super Smash Flash 2, the move possesses considerably more knockback than it's counterpart in SSF, and can now be used for recoveries as it makes Mario hover in the air and move around with ease. It is also one of the best momentum canceling moves in the game. This move slightly differs from the normal Mario Tornado in that Luma from Super Mario Galaxy comes out of Mario's hat during the ending strike to deal extra damage.

Fire Mario's variant is the Firewall Star Spin. It replaced the Fire Mario Eruption in v0.5a of the SSF2 Demo. The move is mostly similar with the difference is engulfs Fire Mario's arms with fire and delivers the final blow with his fists exploding to give more damage. Unlike the regular Star Spin, in v0.9a, Luma doesn't appear at the end of the move.

It is unknown if Luigi will use this move in SSF2, or use the Brawl version of the move instead.
