Mercurians have adapted to living on the closest planet to the Sun in a number of ways. Their skin tone is a shade of pink that can be likened to a permanent deep sunburn, and they are completely hairless. Their internal temperature can reach to very high levels, and they can control their body heat with practice. They can absorb and project this heat either by touch or by proximity. This heat can also be used for healing purposes, such as medically soothing a sore ankle. If ever needed, they are able to do an offensive attack by shooting fireballs from their mouths.
