Caius Ballad

Paddra Ballad-Caius, or Caius Ballad is the main antagonist of Final Fantasy XIII-2 who also appears in Lightning Returns: Final Fantasy XIII. Caius engages his fated rival, Lightning, in an endless battle in the realm of Valhalla, and follows Lightning's sister, Serah Farron, and his former protégé, Noel Kreiss, on their journey through time.

Caius was originally a Gran Pulse l'Cie charged with protecting the seeress Yeul as her Guardian.

In Lightning Returns: Final Fantasy XIII, Caius continues to serve as Yeul's Guardian, and he faces Lightning in battle once more.

His full name stands for "Caius of the Ballad clan, from the city of Paddra".
