so this dude has no eyes [but can still sense his surroundings], a tailmouth that can breathe some sort of poisonous/radioactive gas, his tongue is super long, his paws function as hands, he has super sharp teeth, he has semi large ears, black hair that covers his face, and is about 8'10. he heals abnormally fast [kind of like Wolverine], and is mostly immune to acids, toxins, poisons, etc. they can still harm him, but they won't kill him.
usually.
his name is Coal.
