Perceval is a Rare Blade in Xenoblade Chronicles 2. He can grant tremendous power to his Drivers, Rex, Nia, Zeke or Mòrag, and their allies. Perceval uses the dark element, wields a Chroma Katana, and acts as a Tank in battle. He carries two battle standards on his back, and fire-like energy spills out the back of his head.
It has been implied that in a previous life, Perceval was far more ruthless than he is in the party. With the more benevolent and merciful nature of the party, the current Perceval no longer seeks to kill an opponent. Instead, he finds that spending the rest of a life in a prison to be a more merciless punishment than killing someone. However, he has strong preferences for working alone and has trouble accepting the help of others.
