Hideous Zippleback

The Hideous Zippleback is a two-headed snakelike dragon. One of it's heads breaths out flammable gas, and the other ignites it. A Zippleback's heads have two different personalities. When the two heads argue, the entire dragon stalls out, leaving it open to attack.

Appearance
Hideous Zipplebacks are very long and serpentine in stature. They have short legs, and short, triangular shaped wings. Both their heads and tails are split in two. Instead of sharp spines down their backs, they have flat 'plates'. They can interlock their necks with these, in the same manner as a zip, hence their name zippbleback.

Abilities
Each head has a different ability. One head breathes a sickly green gas that, if inhaled by humans can make them feel dizzy and nauseous. The other head emits an electrical spark, which can ignite the gas. With this, they can be tactical ambush predators, or they can go out in a full offensive, by biting their tails and rolling in their fire for a devastating, high speed attack.

Strengths and Flaws
They work as a team, and are masters of ambush attacks. However both heads have a different personality. This means sometimes, depending on the dragon, they may not get along well with each other. One head controls one side of the body, so if they are not in agreement, they can 'stall out' and become incapabable of coherant movement.

Habitat
Woodland Areas, perfect places for them to hide in the shadows.

Preferred Training Methods
Both heads need to be given attention at the same time, to avoid bickering and jealousy. This is why most Zippleback riders are a pair, and those with one trainer have a lot of difficulty.
