Universe

A character's universe refers is the series of games (the franchise) he or she is tied to. For instance, Link is the main hero in games from the Legend of Zelda^TM series; thus, he belongs to the Hyrule universe. Falco is a supporting character in the StarFox^TM series; thus, he belongs to the StarFox universe.
