Hellfire wyrm

Hellfire wyrms are dragons sponsored by the hells to influence events on the material plane.

Description
Large bone spikes jut from the head and shoulders of these dragons, while smoke is continually emitted from their scales, seeming to flow like molten lava across their massive bodies. Their eyes burn bright yellow and they reek of brimstone. However, when they appear before humanoids, they usually take the form of a tiefling.

Combat
Hellfire wyrms prefer to manipulate people and politics from behind the scenes, however, if they should be forced into a combat situation, they excel at tactical maneuvers, able to turn enemies into friends and blast the rest with their powerful breath weapon. They also have the ability to temporarily summon Baatezu allies and burn anything that gets close to them.
