Flying Shot

The Flying Shot is an offensive power shot in Mario Tennis: Power Tour. It is used by Sass in the story mode, and can be unlocked for usage by the player character upon having L2 Jump, L4 Muscle. Once activated, the user will perform two small hops, before leaping high up into the sky encased in flames and crashing down onto the tennis ball while the background turns purple, causing an eruption and shooting the ball towards the opposition's side of the court at an incredible speed. If the opponent returns this shot, they will instantly be blasted as far back as they can be from that position.

Origin
Due to Power Tour's similarities and references with the Golden Sun series, it is likely that the Flying Shot was based upon the Planet Diver move from said series.
