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 (Quixotic Tutelar)
 * Poppi QTπ (Quantum Technochampion π) (optional)

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