Magicant

Magicant is a new Stage introduced in Super Smash Bros. for Nintendo 3DS and Wii U from the EarthBound universe.

Stage Description
The stage has 3 platforms, sometimes Flying Man will appear and help the player who is near him, and then attacks the other players, much like a Assist Trophy.

Origin
Magicant (also referred as Your World) is a location in EarthBound. It is entered after gaining all the parts of Eight Melodies, and is entered by Ness alone. There, all memories breathe life, as Ness encounters family members, his past selves, defeated enemies (Everdred for example), and even snowmen long melted. The only way to exit from Magicant is by entering the Sea of Eden, Ness's subconscious, and defeating Ness's Nightmare, the essence of evil in Ness himself and has all of Ness's abilities. Its defeat allows Ness's subconscious to talk to him and let him absorb Magicant and to awaken his true strength, prompting a massive power boost.

In Mother, it is a location and is the haven of Queen Mary. When Ninten and friends arrive, the Queen is suffering from amnesia. After gaining all Eight Melodies this amnesia dissipates and she remembers she is actually Maria, and it is revealed that Magicant is simply a product of Maria's consciousness.
