Why does this just look like an edit of the fire dragon? That's because it is. I mostly just wanted to try and play around with fire here.

The hellfire is very similar to the fire dragon, and from a distance, it may be hard to tell which is which. But when close up, they are quite different. The hellfire dragon has spouts of fire constantly coming out of its body, not having hair as a tradeoff, and wings made of fire. While already more dangerous due to the defensive fire on its body, the flames that a hellfire dragon spews are far more dangerous than a normal fire dragon. Firstly, the refuse to go out. Only once their fuel source is gone do they go out. Secondly, they're magic flames. While some creatures, such as fire elementals, could normally harness the fire that a fire dragon spews all over them in aggression, a hellfire dragon's flames will burn these fire-absorbing creatures as if they were made of flesh. Other than this, hellfire dragons act very similar to normal fire dragons, and can even be found in fire dragon dens from time to time.
