Moonsault Slash

The Moonsault Slash is an attack used by Charlie Nash in Street Fighter V. The attack can only be performed from the air and resembles an inverted Flash Kick. The EX Version features two Moonsault Slashes strung together, with Charlie using the momentum from the first kick to twist in the air and launch a subsequent Slash.

Tactics
The Moonsault Slash is one of Charlie's best tools to approach and pressure the opponent, with both the light and medium versions being quite safe on block. The heavy and EX versions of Moonsault Slash are far more unsafe, but deal much more damage and are quite good at air-to-airing attacks, something that the light and medium versions are somewhat poor at.

Trivia
The Moonsault Slash resembles the Genocide Cutter, an attack used by Rugal Bernstein, a character from SNK Playmore's The King of Fighters series.
