Madeen (summon)

Madeen, also known as Maduin, is a recurring summon in the Final Fantasy series, first appears in Final Fantasy IX.

Final Fantasy IX
Madeen is disguised as a moogle named Mog, who lived and grew up with Eiko Carol in Madain Sari. When Zorn and Thorn kidnap Eiko and take her to Mount Gulug, Mog comes out of Eiko's pocket and goes into Trance, revealing herself as the eidolon Madeen.

Madeen urges Eiko to use her special ability, Terra Homing, which eliminates Zorn and Thorn. Afterward, Madeen reminds Eiko she will always be with her before disappearing entirely. Madeen is never referred to as a male eidolon, even after abandoning its female form, so this is the only game in which it is assumed to be female.

Eiko can learn to summon Madeen for 120 AP from the Ribbon add-on, which is obtained as part of the story when Madeen is first revealed to Eiko. Madeen's summon attack is Terra Homing that deals Holy-elemental damage. Madeen's spell power increases with Eiko's level (see Summon (Final Fantasy IX) for damage formulae), and costs 54 MP to summon.

Final Fantasy Tactics Advance
Madeen can be learned from the Cheer Staff by the Summoner class. It uses the most MP of all the summons in the game, taking 36 MP and needing 300 AP to master. This summon deals Holy-elemental damage to all targeted enemies, and has a Magic Power of 52. It is stealable through the ability Steal: Ability, and is also susceptible to Return Magic and Absorb MP.

Final Fantasy Tactics A2: Grimoire of the Rift
Maduin is a Holy-elemental esper, and similar to its Final Fantasy Tactics Advance appearance, deals Holy damage to all units within a large area, and is learned by the Summoner from using the Cheer Staff. It requires 350 AP to master and 24 MP to cast.

Crystal Defenders
Madeen appears in this game not as a summon, but a boss.

Dissidia Final Fantasy
The description of Maduin's Fang refers to the Final Fantasy IX Madeen as Maduin, marking the first and only time he shares the same name with Maduin from Final Fantasy VI in the same Final Fantasy title.

Final Fantasy All the Bravest
Madeen is the sole eidolon that Eiko can summon in Final Fantasy All the Bravest. It performs Terra Homing when summoned.
