Dioscuri

The Dioscuri, also known as the Dioscuri twins, appear in Fate/Grand Order (FGO) as a Saber-class Servant, possessing characteristics of the Avenger class. They are the twin gods of Greek mythology, consisting of the elder brother Castor and the younger sister Pollux, symbolizing the constellation Gemini. Castor harbors resentment for not being the son of Zeus, manifesting as an Avenger, while Pollux, as the daughter of Zeus, possesses immortality and masterful swordsmanship, appearing as a Saber. Despite being two separate entities, they are also a single heroic spirit. In FGO, the Dioscuri possess excellent NP gain and critical hit capabilities, along with skills that enhance their attack power. Their Noble Phantasm, 'Dioscures Tyndaridae,' is a single-target attack with invincibility pierce and defense ignore, making them ideal for high-difficulty challenges. Additionally, their design and personalities are popular among players, contributing to their high popularity in FGO.
