Spirits are a "family" of enemies in Xenoblade Chronicles. They are only found in the Memory Space and are meant to represent Shulk's journey and as such are in the likeness of his fallen foes. They are the four last enemies fought before the final battle against Zanza.
Additionally, there is an entry on the enemy name table for a spirit version of Disciple Lorithia. However, no corresponding model exists in the game's files, and the entry lists the model for the Asara Telethia instead.
