Subcon (species)

The Subcon are a peaceful fairy-folk that reside in the land of dreams (which is also named Subcon). During the events of Super Mario Bros. 2, the evil tyrant Wart took over the land of Subcon and imprisoned the Subcon fairies in a vase. After Wart was defeated, the fairies were released. They then picked up Wart's battered body and carried him off-screen where he was either disposed of, imprisoned in jail, or exiled to another land (perhaps even the dream world of Koholint Island in The Legend of Zelda: Link's Awakening).

Additionally, the Subcon fairies may have been the mysterious voices that called Mario, Luigi, Peach, and Toad to the dream world of Subcon, thus starting their adventures in Super Mario Bros. 2.

Name Confusion
The name of these fairies is subject to much debate. In the game's credits, the fairies were named Subcon, even though the setting of the game was also named Subcon. Since there are many mistakes in the game's credits (one being that the Subcon fairies appear in the enemies section), these fairies may not be actually named Subcon. However, if the name is incorrect, it should have been corrected in subsequent remakes of Super Mario Bros. 2 (like other mistakes). Since the name has not changed, this implies the correct name for the fairy-folk is Subcon, despite the fact that Subcon is also the name of the land they live in.
