Poppi

Poppi is a character in Xenoblade Chronicles 2. She is an Artificial Blade constructed by Tora due to him being unable to become an actual Driver. He made three versions of her:
 * Poppi α
 * Poppi QT
 * Poppi QTπ (optional)

Poppibuster is not considered a version of Poppi and can only be used by Drivers other than Tora.

Poppi makes a brief appearance after the defeat of Z. She is seen at the Cloudkeep after being freed, running up to Nia. They later view a photograph of an older Rex, Pyra, Mythra, and Nia herself with their children, as well as their friends as Aionios splits back into the worlds of Bionis and Mechonis, and Alrest.
