Tornado

Tornado is ' Final Smash in Super Smash Flash 2. It was confirmed on July 29, 2018, in the Beta 1.1 release announcement video.

Overview
When performed, Tails boards the Tornado biplane. With the help of a reticle to trace its direction, it then comes flying by on the stage from one side to the other, dropping bombs in its path. each of them dealing 20% with moderate knockback, being hit by the biplane itself deals 36% with incredible knockback. Tails flies from the sides three times before ending the Final Smash with a pose.

Origin
The Tornado is a plane constructed by Tails prior the events of Sonic the Hedgehog 2, where it made its first appearance. Since then, it has been featured in many other  games. It is typically piloted by Tails, while Sonic or other characters walk on its wings. The plane is owned by Sonic himself, and as such he has also been seen to be the pilot at times. Often in the Sonic series, it is shown towards the end of each game where it usually arrives just in time to save a character from falling to his or her death. It has since become a staple icon of the series.

The Tornado that Tails uses in SSF2 is based most closely on the Tornado's original appearance in Sonic the Hedgehog 2, though its aesthetic design is closer to that of the Tornado in Sonic Adventure.

Trivia

 * Prior to v0.9a of the SSF2 Demo, the Tornado was used as Tails' revival platform.
 * Prior to Beta, this Final Smash worked much differently; Tails would instead fire cursor-controlled bullets and bombs from the Tornado at a foreground perspective.
