The Chimera is a peculiar creature that seems to be made of various random materials. Its torso, which bears its large Heartless emblem, is made of strips of grey and light grey metal. Its hips, which are connected to the torso by a thin, red, chain-like piece, are very small, and are made of the same material as the torso. Its legs are very thin and have the same material as the torso, and its feet are two small jars filled with a murky, green liquid. Its left arm is very large, almost reaches the floor, is made of the same material as its torso, and ends in a metal, four-fingered hand.
The Chimera's right arm is shorter and is comprised of bellows-style segments alternating color from pale yellow to light blue. Its hand is an odd, red contraption with yellow joints that ends in a large, silver, pincer-like appendage. Its head is a massive jar filled with the same murky, green liquid as the feet along with three spherical heads. One head is orange and resembles a smiling jack o' lantern, the second is white and seems to be frowning, and the third is pale blue with angular, spiral eyes. Around its neck, the Chimera wears a black collar with red spikes.
In genetics, a Chimera is a single organism that has multiple and distinct cell populations; simply put, it is a creature made of multiple creatures.
The Chimera appears at the Manor Ruins, but will not always spawn when Sora enters the area; if it does, it will appear after a few waves of Wight Knights are defeated. Whether or not is has been activated already, the nearby Red Trinity serves as a visual indicator of the Chimera's presence, as it disappears if the room is set to spawn the Chimera, though this only applies if the Red Trinity has been claimed already. Another way to know that the Chimera may spawn is if a Wight Knight appears under the archway near the river.
A strong physical defense build is essential when preparing to fight the Chimera, along with the highest-strength Keyblade on hand. The Chimera has tactics to explode and cause wide-area damage, and can create four new enemies (Gargoyles). Having party members cast support spells such as Aero and Cure can be useful. Thunder and Blizzard are also handy for offense.
The Chimera has two different sets of HP: one when first encountered and a second, longer set when the three heads fly out of the jar it carries. Depleting the second HP bar ends the fight, but its defenses are extremely high at this stage; the trick is to repeatedly strike the colored heads that bounce around, knocking them back at the main body and dealing much higher damage than regular attacks are capable of. If the second HP bar hasn't been depleted after a set time, the heads will fly back into the jar and Sora must take out the first HP bar again.
A good strategy is to take out the surrounding Gargoyles first; casting Gravira or Graviga on Chimera just as it is summoning them will hit both the Chimera all four of its minions, knocking off most of their HP right off the bat. A single Thunder spell should finish them off; alternatively, leave them for your allies to take care of and focus on Chimera at this point.
The Chimera has attacks that can knock back Sora and the party so maintain safe distance where possible. The main threat lies in its high damage and wide-area attacks, thus optimized defense and high-strength party-wide healing are a strong asset for the fight. Its attacks are, however, fairly easy to dodge. Stay in the air and hit it with aerial combos to avoid its shockwave attack, and dodge roll out of the way of its flying corkscrew strike, to keep damage to a minimum. It tends to corkscrew when low on health in its first HP bar, so knocking its health down to zero with a rapid flurry of attacks is also a solid option.
To increase the number of Blazing Stones the Chimera drops, reflect the heads it releases nine times, and it will drop one for free. This is easiest to perform successfully when the Chimera is atop the rock; it will always jump there to summon its Gargoyle minions. Cast Aeroga for best effect in deflecting the bouncing heads more easily.
