You are all a part of the process... the output of the evolutionary plan conceived by the Crystals I created. In other words, this is all my work... The Crystals, the Maenads, and this new moon. This is why I am called the Creator!
- —The Creator
The Creator (クリエーター, Kuriētā?) is the main antagonist and final boss of Final Fantasy IV: The After Years. It occupies the True Moon, which it utilizes as a vessel for interstellar travel. The Creator is the last surviving member of a species which once prospered on the distant edge of the universe, but ultimately destroyed its own civilization.
Concerned about whether or not evolution was a necessity and wishing to conduct experiments regarding the evolution of life, it created a host of Crystals capable of recording the history of a world and distributed them upon planets which held the promise of life, including the Blue Planet. The Creator and its Subterrane are even stronger than Zeromus's. Edge remarks that Zeromus's moon "has nothing" on the Creator's.
Cecil glimpses the Creator in a vision telling him it has found a new form, namely for the Maenads, and that he is unable to comprehend its existence. The Creator appears to Cecil as a featureless glowing orb of green light.
The Creator mass-produces and dispatches the Maenads to recover the Crystals of the Blue Planet. It deems the planet's races evolutionary failures whose continued existence cannot be permitted, and, like the worlds of other inferior races, attempts to devour the Blue Planet with the True Moon, which is revealed to be the remains of a space fleet once manned by the Creator's race.
The party gathers and sets out to stop the rapidly approaching moon. Within True Moon's depths the party destroys Crystals protected by other worlds' life forms — bosses from throughout the Nintendo era of the Final Fantasy series. The group encounters the Creator encased in a cocoon-like shell and after the shell is destroyed, the Creator emerges and explains its true nature, then attacks in earnest. The party battles it for a while before it loses its sanity as the cocoon they had destroyed had been keeping it in check. Without the containing machine, the Creator undergoes a series of mutations before defeating the party.
Back on the Blue Planet the people left behind are busy fighting off moon-crazed monsters when they realize Cecil's group is in danger. They send their prayers to the True Moon joined by the wishes of the party members still aboard the Lunar Whale. The Crystals they picked up shortly before the fight awaken the five warriors, and after using one or more Crystals on the Creator, they defeat it. The vessel begins to collapse from the stress of the battles and the core's destruction.
The party attempt to flee with the Creator in close pursuit and Maenads helping to hold it off. After several encounters the Creator is defeated when the last Maenad unleashes a Meteor spell that destroys them both. The Creator's final words are "Thank you", implying the Creator only undertook its quest due to insanity brought on by its civilization's destruction, and had the craze broken when the Maenad awakened it.
As the sole survivor of a civilization much more advanced than any other known civilization, the Creator is immensely powerful. It created many Crystals that were scattered around many worlds, which had the ability to allow any civilization to prosper and also collected data. Many of the Crystals contain data from creatures of many games of the series, which shows the vast reach of his extent. Using the data collected from Rydia, the Creator created the Maenads. It is far more powerful than Zeromus and can use devastating magic, and even control a Moon with its power.
When weakened the samples collected from his core allow it to transform and become more powerful, but The Creator loses its sanity in the process. In its final form the Creator becomes a deformed monstrosity with access to several powerful abilities, such as control over high level magic, blasts of energy, regeneration, and duplication, albeit these copies and its own final form are so unstable they damage themselves over time through Metastasis. Only a Meteor spell from the Maenads is powerful enough to destroy it for good.

The Creator is the game's final boss fought in four different forms. The first form is concealed inside a protective pod / life support system. In the second form, a feminine humanoid with a rabbitlike head and a degenerated, bloblike appearance emerges from the pod, connected to various tubes. In the third form, the humanoid transforms into a slender, androgynous form with long hair. In the final form, the Creator's upper body resembles a winged female angel, wearing a strip of cloth, attached to an immense, monstrous lower body. In the 2D versions the creator's lower body is a mass of random monstrous bodyparts trailing a series of organic cords, while in the 3D versions the Creator's lower body is more fishlike, with a single, larger trailing cord. The last form starts as a scripted battle, but after a cutscene, the player can defeat the Creator.
The Creator has a total of three battle themes. The first is "Master of Creation", which plays during the battle with its core. The second, "Straying from Evolution", occurs when the party faces its evolving forms. "The Battle for Life" plays when Creator takes on its final phase.
