The Guardians

The Guardians are a group of people chosen to combat the evil of The Dark One. Each one is an embodiment of a different element and are seen by those who know the legends as the reincarnations of the original chosen ones. They serve as protagonist in the Yu-Gi-Oh! 5D's: Force of the Guardians series, alongside the Signers.

The Legends
Many times throughout the Earth's history, an evil being known only as The Dark One would rise in the form of a human an try to rule all the world. To combat The Dark One and return balance to the universe, the "gods" would select one who they felt best represented one of the core elements of the world and of life itself to serve as the world's Guardian. This chosen one would fight, ultimately to their death, to defeat The Dark One and end his reign. This would continue until thousands of years after the first appearance of The Dark One, where all the powers of the Guardians would combine to destroy The Dark One once and for all.
