Chaos is fought as the final boss . Musical themes . While in the NES version Chaos used the standard battle theme , later editions gave him his own music , as well as increasing the difficulty of the fight . In the NES version his battle ' s music is " Battle Scene " , while in the WonderSwan Color version " Last Battle " plays . In " Theatrhythm Final Fantasy " the theme used in the Battle Music Sequence ( BMS ) is an arranged version of the " Chaos Shrine " theme , which can also be heard in the menus for the Chaos Shrine section of the game . Other appearances . " Dissidia Final Fantasy " / " Dissidia 012 Final Fantasy " . Chaos is the God of Discord and the main antagonist . He summons enemies from other universes to defeat Cosmos , the Goddess of Harmony , who has summoned heroes to fight Chaos ' s forces in an endless cycle of war . " Dissidia " and " Dissidia 012 " give conflicting explanations for Chaos and his relation to Garland , as the Cosmos Reports and Chaos Reports from " Dissidia " and the Reports in " Dissidia 012 " present a different origin . Chaos is a manikin created by Onrac researchers and Cid of the Lufaine to be used as a weapon against other nations . Raised by Cid and his wife until he matured , Chaos was taken away by the Onrac military and a manikin of his mother , Cosmos , was used to coerce him into obeying . When Cid and his wife attempted to rescue Chaos , his mother was shot , and in his hatred Chaos opened a portal to the Interdimensional Rift , which drew him , Cid and Cosmos into World B , where the events of " Dissidia " and " Dissidia 012 " take place . In this new world , the three were met by Garland who felt he and Chaos are linked . Cid made a deal with the holy dragon Shinryu for Chaos and Cosmos to war to perfect Chaos ' s power , at which point they will return home to seek revenge on Onrac . Chaos ' s memories faded over time , and by the time of " Dissidia 012 " his memories of his past with Cid and Cosmos are gone , the only fragments left coming to him in dreams . Garland tells Chaos that before Cid called him to World B to partake in the cycles and that Chaos is to send him back in time 2000 years to become Chaos himself . As the cutscenes of the original " Dissidia " were unchanged for " Dissidia 012 " , it may be that this cutscene ' s revelations were retconned by the Reports and are no longer canon , or that Garland ' s transformation into the " Final Fantasy " Chaos might have influenced the creation of the " Dissidia " Chaos via the memories used to create the deity . The truth of this relationship is left uncertain . In " Dissidia 012 " , Chaos returns as the God of Discord along with his previous warriors . A bestial form of Chaos , Feral Chaos , is introduced . This incarnation is the result of Chaos going berserk after winning too many times against Cosmos in a nightmare world Shinryu has imprisoned Cid in . When five warriors manifest in this nightmare world , they destroy Feral Chaos , shattering the nightmare and freeing Cid . As he dies , Feral Chaos regains his senses , and thanks the warriors for freeing his father . " Theatrhythm Final Fantasy " .
