A moonsault, moonsault press, or back flip splash is a professional wrestling aerial technique. It was innovated by Mando Guerrero. Much of its popularity in both Japanese and American wrestling is attributed to The Great Muta, despite it being used in North America by "Leaping" Lanny Poffo years before Muta came from Japan. In a standard moonsault, which is generally attempted from the top rope, a wrestler faces away from the supine opponent and executes a backflip landing on the opponent in a splash/press position but facing towards the elevated position. Though this move is generally attempted from the top rope to an opponent lying face up in the mat, myriad variations exist, including moonsaults that see the wrestler land on a standing opponent and forcing them down to the mat. The move is considered a higher-impact version of a splash, since the wrestler utilizes rotational speed. A less common variation sees the wrestler perform a moonsault on a standing opponent, with the torso of the wrestler striking the torso of the opponent (albeit upside down), forcing the opponent backwards and to the ground with the opponent on top of them, usually placing the opponent in a pinning predicament. Most of the variations listed below can also be performed on standing opponents. Danger and precautions When executed properly the moonsault is generally considered safe, but as with any aerial maneuver, there is inherent high risk when not executed properly. The wrestler performing the move often misses and lands on their stomach unharmed (such as Keiji Mutoh during Starrcade (1989), when he went for a Moonsault on Sting, but ended up missing; he was eventually able to land on his feet and land a kick). Mutoh underwent double knee replacement surgery on February 18, 2018, and has since then not performed the Moonsault. In an interview with Tokyo Sports, Mutoh told them that he was lucky to be alive after botching a moonsault. In an example of a moonsault gone spectacularly wrong, Eiji Ezaki, better known as Hayabusa, suffered a life-threatening injury on October 22, 2001, while working for the Japanese wrestling promotion Frontier Martial-Arts Wrestling. As Hayabusa began executing a springboard moonsault from the second rope, his feet slipped off the rope and struck the first rope below. As a result Hayabusa did not have enough height within which to execute the full 360° of the move, causing him to
