A stalwart consigned to the endless cycle of battle, he enjoys dueling with stronger foes.

A knight sworn to face the Warrior of Light. He wields a powerful, adaptive weapon.—Dissidia Final Fantasy description
Garland is the fallen Cornelian knight who resides in World A. He kidnaps Princess Serah due to a “misunderstanding”, however, his true intentions were to create a time loop. As he tells the Warriors of Light on World A:
Do you remember me? I was once known as a knight of Cornelia. Two thousand years from now…you killed me. I am Garland. Oh, you did defeat me. But the four great forces saved me by sending me back through time! Once here, I sent the four Fiends into the future…where they shall once again use the four great forces to send me into the past! In two thousand years, I will remember none of this. But I will be reborn again here. So even as you die, again and again, I shall return! Born again into this endless circle I have created!
Yet, according to Dissidia, Shinryu summons him to World B, not Chaos. This is because he IS Chaos:
Garland: “Chaos…if this is to be our final battle, there is something I must share with you. That this conflict, which has endlessly repeated itself, is according to the Great Will. And I am the one who has made this world the battleground for harmony and disorder. You had no memory, so I guided you in accordance to the Great Will’s wish.”
Chaos: “It was just as I thought… You were the beginning.”
Garland: “No, Chaos…For myself…you are the beginning. Before the Great Will led me to this realm, when I was on the edge of death, it was you who sent me two thousand years into the past. You are me… and I…am you.”
From his admission, Garland arrived at World B after his first defeat against the Warriors of Light. But, what caused misunderstanding to abduct Princess Serah? Perhaps it was the endless cycle themselves. This would place his arrival to World B before the events of World A.
Yet, this creates a paradox; Garland would experience the events of World B before World A. Yet, Garland creates World A through World B. Could this paradox have some validity? A third scenario pictures his 2,000-year time travel, roughly after summoned by Shinryu. There, he and Chaos merge. However, it creates a similar paradox.
