What it looks like:

The unicorn’s have a black body, which is rare for unicorns, and black eyes like buttons. Their skin is rare since it’s fireproof and they don’t feel the heat. Interestingly it has orange, red and yellow mane like fire to blend in with its habitat. Another rare trait for unicorns is breathing fire, this is because only a small amount of unicorns live in places with fire/hot places. The dark unicorn has red glowing eyes. 

Its habitat:

This species of unicorn are hard to find since they live in volcanoes. Some go out and venture into the depths of the burning forest. Weirdly they sleep on burning rocks. To them this is comfortable since the rocks only let off a good temperature of heat, hot and cold. 

What it eats:

They eat on hot rocks and drink lava. The lava enters a part of their body, which no other species of unicorns can do, to make it so that they can breathe it out. However the ones that live in burning forests eat the crispy burnt leaves. 

Powers it has:

When they are in a fight they can flow the lava up to their horn and out the tip. Their horn is very sharp so its like a needle going in and injecting lava into their opponent. They can also set their mane on fire or they can make the colours of their mane light up so it makes it look like its setting on fire to scare their opponent. When fire is near they can take control of the fire.
