A Flying Man is one of the many fictional characters in the Mother series. It appears in both Mother and EarthBound, with minor roles in the storyline, in each game's Magicant. Flying Men are found inside a house, and they are five in total. If talked to, a Flying Man will join the protagonist's party until he is defeated, as long as no other Flying Man is already there. Once defeated, he will be buried at his home and will never be able to be revived.
Super Smash Bros.
The flying man appears on the Magicant stage in Super Smash Bros. for Nintendo 3DS as a stage hazard which will help whoever touches him first with flying cross chops that do decent knockback and damage. The Flying Man can be defeated though another one will spawn soon after. In addition, a grave appears when they are defeated and there is a max of 5 of them per match similar to how they acted in the game.
