Tlalocoatl

The Tlalocoatl, also known as the rain dragon, rain serpent, or Maztican dragon, is a creature unique to the continent of Maztica. The feature that most distinguishes tlalocoatls is the fact that these dragons have two heads and no tail. One head is the head of a serpent and the other is a jaguar head. These creatures are usually bluish in color and have turquoise scales on the upper part of their bodies.

Combat
Each head of the tlalocoatl has a breath weapon. The serpent head may breathe a cone of ice crystals and the jaguar head breathes a cloud of water vapor which can be scalding steam. Tlalocoatls can also wrap themselves around an opponent to cause constriction damage. In addition to their other abilities, tlalocoatls have limited spellcasting capabilities.

Ecology
Tlalocoatls aren't extremely greedy but do appreciate valuable objects including cocoa beans, coral and gold dust. These creatures are often servants of the rain god Azul and help to bring rain to Maztica.
