Chimera

The Chimaera (キマイラ) is an Emblem Heartless that is found in Kingdom Hearts Final Mix. The Chimaera's limbs appear to be made of seemingly random items; they also are very unproportional to each other. Inside of its head tank are three masks, representing Lock, Shock, and Barrel. Chimaera can only be found in Halloween Town.

Strategy
They frequently call upon Gargoyle Heartless as their health decreases, which is mostly only equaled by Behemoths, so be prepared for a tactical battle.

Chimaerae are the only Heartless in Kingdom Hearts Final Mix to drop a Blaze Stone.

The Chimaera isn't an easy enemy. It has tactics to explode and cause wide ranges of damage and can create four new enemies. Having party members cast support spells can be useful such as Aero and Cure. Thunder and Blizzard also will come in handy when fighting this creature, but the most important thing is to come prepared defensively but also with a weapon powerful enough in order to actually damage him.

Whenever the Gargoyle Heartless arise use spells or minor attacks to take those out first before getting back to the Chimaera as those enemies can become pesky while you try to hurt the larger beast. The Chimaera has attacks that can throw Sora back when he tries to attack so watch out. One of the reasons the Chimaera is so deadly is that it can inflict high damage and in a wide range causing multiple party members to get hurt. Support spells, again, are very important.

To increase the chance of the Chimera dropping a Blazing Drop, reflect the bolts it shoots out at you when it's passed out nine times. Cast Aeroga for best effect.

Etymology
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.

Trivia
