Terminan

Terminans are people who live in the land of Termina - widely believed to be a parallel world to the world of Hyrule. The people in this world are almost exact duplicates of the citizens of Hyrule. The only game where Termina is playable is Majora's Mask. One theory suggests Nintendo simply re-used sprites they already had from Ocarina of Time, as well in the real world they do say everyone has a twin, so Termina is not necessarily a parallel dimension as simply another country.

Examples of duplicate persons

 * Talon - as Mr. Barten in the Milk Bar.
 * Malon - Appears as Romani and Cremia. (Cremia is the equivalent of the older version of Malon, as Romani is the equivalent of the younger Malon.)
 * Ingo - Appears as all three of the Gorman Brothers.
 * The Happy Mask Salesman? - This one is a strange character as he seems to be able to traverse between Hyrule and Termina whenever he wants.
 * Koume and Kotake. But not as Twinrova.
 * Princess Ruto - Appears as Lulu in the the Zora band, The Indigo-Gos

There are three possible reasons why the Sprites are the same as in Ocarina of Time. 1. To make Termina seem more friendly to players of Ocarina of Time by bringing back familiar faces. 2. To make Termina seem like a parallel world from Hyrule. Or 3. The game designers were lazy, so they just smacked on old characters from Hyrule into Termina.
