- “A mysterious little creature, he makes himself useful by transforming into a weapon for Serah. No one knows much about this strange animal who calls himself her guardian. People were led to believe that moogles don't exist, and those who meet him for the first time assume he is merely a stuffed animal. Although shy at first, once he opens up, he is quite the chatterbox, teaching Serah and Noel all about the world and its history.”

Mog (モーグリ, Mōguri?) is a supporting character in Final Fantasy XIII-2 accompanying Serah Farron and Noel Kreiss on their journey through time, teaching them about the game's mechanics, and acting as Serah's weapon in battle. In Lightning Returns: Final Fantasy XIII, Mog leads the Moogle Village in the Wildlands of Nova Chrysalia.
Although officially called "Mog" some official material calls him The Moogle or just Moogle, for example in the EU wallpaper. In the Japanese version of Final Fantasy XIII-2, Mog is referred to as "Moogle" and rarely called "Mog". His entry in the Datalog of Lightning Returns: Final Fantasy XIII suggests his real name is not Mog and that he doesn't know his real name.
Mog originates from the Ocean of Time, a place abundant with moogles. While playing hide-and-seek with his friends Mog was sucked into a paradox, losing his memories of his home, friends, and family. Mog drifted into the Void Beyond and during his travel encountered a chocobo chick and many other various creatures in many humorous encounters, including those with five flan, a Centaurion Blade, an Imp and his Ahriman friend, and the Proto fal'Cie Adam.
In Final Fantasy XIII-2, Mog can not only transform into Serah's weapon, but can execute the Mog Clock pre-battle system and detect hidden treasures on the field with Moogle Hunt. Mog can be thrown by Noel or Serah toward out-of-reach areas through the Moogle Throw command. (more...)
Screenshot of Inside Sin from Final Fantasy X. For the game's final dungeon, the party enters Sin itself, intending to find the spirit of Yu Yevon and destroy it. In the deepest area of Sin's innards, the party finds Jecht, who speaks to Tidus and Auron before transforming into Braska's Final Aeon, the current core of Sin that must be destroyed to force Yu Yevon from its body. This final area where the Final Aeon is fought is a recreation of Zanarkand's blitzball stadium called "Dream's End", floating over a ruined Zanarkand and a field of lava. The emblem of the Zanarkand Abes hovers over the stands, and lights up in fire when Braska's Final Aeon shifts to its second form.
Dream's End returns in Dissidia Final Fantasy and its prequel Dissidia 012 as the representative arena of Final Fantasy X. At the end of his storyline in both games, Tidus fights Jecht here.
