Chaos is the primary antagonist and the final boss of Dissidia Final Fantasy and Dissidia 012 Final Fantasy. He is the god of discord that opposes Cosmos, the goddess of harmony, both being equal in power. During Dissidia Final Fantasy, Chaos and his forces tip the balance of power in their favor, setting the stage for their victory. Dissidia 012 Final Fantasy explores this shift in power in-depth, and the actions taken by hero and villain alike that set the stage for the thirteenth cycle.
As the final boss Chaos is unplayable unless one hacks the game. An alternate form of Chaos, a bestial monstrosity known as Feral Chaos, is playable in Dissidia 012 Final Fantasy, and serves as the superboss.

Body of Dark, Heart of Light[]
Chaos was implied by a lot of warriors, especially Kuja who described him as the God of Discord opposing Cosmos to Cecil. But he was first seen during Cecil's night terror as he ascended the excruciatingly long staircase and saw the demon himself rising from his throne and confront Cosmos. He demanded to have Cecil serve as one of his promising pawns. Cosmos refused, so he incinerated her with a huge volley of flames! He then gazed at Cecil, paralyzing him and making him succumb to a small Dark Crystal to intensify his dark prowess consuming him!
It was implied by Kuja that he has the same Dark Crystal from Chaos! Cecil saw it in the Crystal World, and it was just his way on manipulating him, and having Kuja a leg up on the competition with the other warriors as he was the weakest and most narcissistic.
Dissidia Shadowgate[]
Chaos was seen during the Prologue as the 10 remaining warriors finally defeated the demon and ended the eternal conflict! The Edge of Madness was blasting apart upon his demise! Although the Behemoth does share traits to both Chaos and Kefka's God of Magic form including his horns, wings, markings, and some of his moves from him and Feral Chaos!
