A Warrior Stone is a gemstone that represent the spirit of each warrior culture. These stones were created by the Zordonians using the power of the Warrior Pearls to defend Earth from the threat of invasion led by Luxos during the Medieval Age, and now they are used to power the Warrior Morpher (PR:WP) in the series Power Rangers: Warrior Power. In the series' Sentai equivalent, Mamoru Sentai Grand Senshi, these stones are called the Senshi Stones.
