Mog is Eiko's pet Moogle in Final Fantasy IX. Unlike the other Moogles Eiko lives with in Madain Sari, Mog has a special fur "collar" around her neck, as well as a golden pom-pom. Mog is very timid, and considered a coward by the other Moogles of the village; as a result, she often runs away even when Eiko is in trouble. The Moogle accompanies Eiko wherever she goes, usually by shrinking herself to hide in Eiko's clothes. According to Eiko, she and Mog were born on the same day and had been thence inseparable. They share Ribbons as a sign of their friendship, which Eiko hopes they can wear together when they are older. Due to her youth, Mog cannot communicate well with anyone except Eiko and the other Moogles.
Mog is first seen with Eiko in Conde Petie, as the two attempt to steal food. They flee into the Conde Petie Mountain Path, but Eiko becomes stuck on a tree branch. The player party catches up with the pair, and Quina Quen immediately singles out Mog as a consumable object. While the Qu chases Mog back to Madain Sari, the remaining party members help Eiko down, and together they follow Mog back to the summoner's village. Mog is later recovered at Madain Sari, Quina having turned his/her attention to fish. Mog also appears as a Tetra Master card.
In Mount Gulug, when Eiko is at the mercy of Zorn and Thorn when they attempt to extract her Eidolons, it is revealed that Mog is actually the Eidolon Madeen in disguise. Mog then goes into a Trance and urges Eiko to use her special ability Terra Homing which seemingly eliminates Zorn and Thorn. After the brief battle, Madeen tells her former charge that she will always be with her, before disappearing entirely. Despite this, the eidolon leaves Eiko her Ribbon, which Eiko can equip as an add-on to learn the Summon Madeen from.
The support ability Guardian Mog, is a unique ability that only Eiko may learn from a Ribbon or a Madain Ring. With the ability equipped, Eiko is cleansed of all status ailments she may have been inflicted with during any particular battle, before the Experience Points and Ability Points are distributed to party members (except for the Knocked Out status). Strangely, even though Eiko can learn the ability early in the game, it does not function until the party receives the first Ribbon item.
