World of Chaos

The World of Chaos is a Heartless that is found in . It serves as the final boss of the game, at the End of the World. It is a titanic battleship to which Ansem bonds himself to for his final attack, and consists of several armaments and cores that must be defeated in order to expose Ansem. As it only appears after the final save point, it is one of the eight enemies in Kingdom Hearts which do not have entries in Jiminy's Journal.

Kingdom Hearts
Following his second defeat to Sora, Ansem transports him, Donald, and Goofy to the Endless Abyss, where the Door to Darkness waits to be opened. Ansem appears before them again, now fused to a gigantic Heartless battleship; he captures Donald and Goofy, trapping them in room of Darkballs and Invisibles, respectively. Sora is forced to fight the now gigantic Ansem on his own, until Ansem is forced to retract himself into the ship. After Sora releases his friends and destroys the ship's Core, Ansem is exposed and forced to fight the three heroes together. Eventually, the heroes destroy the World of Chaos, and when Ansem calls upon Kingdom Hearts to aid him, he is obliterated by the light that sleeps within it. Riku's body is returned to him at this point, but unbeknownst to him, it still contains the surviving traces of Ansem's mind.

Design
The World of Chaos is a titanic battleship and easily one of the largest Heartless seen in the Kingdom Hearts series, and is on par with the Groundshaker in sheer magnitude. It seems to be almost entirely organic and made of twisted, discolored flesh. Its body is very long and flat on top. Its face is on the front tip of its body, and its main core is located on top of its body towards its rear. The core is covered by a twisted, dark pink cage. On top of this cage are Ansem and his Guardian, now much larger—though still small in comparison to the World of Chaos—and heavily altered in appearance. The World of Chaos is colored in a mix of faded pink, cyan, brown, and yellow. Two leg-like protrusions are attached to the battleship's underside. The foremost one, underneath the Heartless's face, is long, thin, and triangular. The rearmost one, underneath the main core, is a wide, thin arc. A long, rocky "tail" sprouts from the World of Chaos's back.

The battleship's Face is demonic and sports a long, pointed chin and a bulbous forehead. Its mouth is filled with large, white fangs and its eyes are fairly small, glowing yellow, and surrounded by black rings.

The Main Core of the World of Chaos is a bulbous, deformed, blue organ covered in violet growths of varying sizes. The most prominent of these growths has a faint silhouette of a skull on it, with the eye sockets, nasal socket, and gaps in the teeth being white. Two smaller growths near the top of this main one are oriented in a way that resembles a Mickey Head symbol. The World of Chaos's various Room Cores are all circular and red with grey edges. They have small yellow spots placed randomly on them and have a thin, blue-green, teardrop-shaped additive floating above its tip and below its bottom.

The smaller of the World of Chaos's two artillery organs are comprised of two jagged, blue tentacles with blue-white tips that clamp together. They are yellow on the inside and grown from purple bumps on the World of Chaos. The larger artillery organs are more ornate, being blue with turquoise additives and smoother edges. They are pink on the inside and grown from large, purple bumps with turquoise patterns on them.

The name of the World of Chaos represents the chaos and destruction brought to the worlds by the Heartless. The former part of its name could also be a reference to the immense size of the Heartless.

Ansem and World of Chaos
During the battle, Ansem wields a large double-bladed Soul Eater halberd. In addition to its own attacks, the World of Chaos itself can summon or throw Bit Snipers.

A shirtless, much larger Ansem has merged with this living Heartless ship, so cast Aeroga and lock onto him. Fly around and inflict damage to him from various angles. Fly away to avoid his Dark Laser technique, then lock onto him again once it is over. Taking him out will send Sora into another part of the ship.

After Sora has defeated the Room Cores, Face, and Main Core, Ansem breaks the seal on himself. He can now use his powerful Great Darkness technique. Simply follow the same strategy as the last battle, cast Aeroga and lock-on.

Room Cores
Appearing during the final battle with the World of Chaos, are three Room Cores that are prisons consumed in darkness. At the beginning of the battle, Donald and Goofy are imprisoned in separate ones. Each of them is within a pitch black zone with the Heartless emblem on the floor, filled with Pureblood Heartless.

Cores are only able to be attacked by destroying all the Heartless in each room.


 * Room Core: Use Graviga to take out vast amounts of Shadows at once. When Sora beats the last one, a sinewy strand appears in the center of the room. Hit it with a combo to be released from the black zone.
 * Room Core (II): When the Artillery are eliminated, a portal appears. Fly into it to rescue Goofy. This battle is similar to the first Room Core battle: simply defeat the Darkball Heartless (which drop MP orbs). Destroy the glowing Room Core itself to free both Sora and Goofy out of there.
 * Room Core (III): The defeated Face reveals another portal. Fly in to rescue Donald. This is an easier fight, since the whole party is back together. The only problem is, the room is full of airborne Invisibles. Beat them with physical attacks, then attack the red Room Core to exit.

Artillery
Artillery are bluish, organic cannons that are part of the World of Chaos. The larger versions are more powerful. When they are destroyed, attacking the World of Chaos becomes a more manageable task, but another set respawns after a set time.

Face
The Face is on the front of the World of Chaos. Sora and Goofy must defeat the Face before rescuing Donald during the Final Battle. Cast Aeroga on Sora and attack with combos, but keep MP to cast Curaga, etc. When the Face's HP is depleted a portal will appear.

Main Core
The Main Core is the "heart" of the World of Chaos, reached after Sora has been reunited with Donald and Goofy. There is not much strategy to this fight. Simply remove the artillery around the area, then attack the organic mass at the center until it is destroyed.
