Pyra and Mythra made their debut in the Xenoblade Chronicles 2 game. They are known as Blades, living weapons, and are specifically of a type called Aegis. Pyra and Mythra are the same Blade, but they have their own identities, each with a different look and personality.

The Mythra amiibo figure is available exclusively in the Pyra + Mythra 2-pack set.
