"Icefire", is a character from the graphic novel / comic book "The Pony Express" by Arielle Namenyi.
"Icefire is a cold, stringent stallion that is the leader of his herd. He is very oppresive and strict about his rules and will not take "no" for an answer. He expects everyone to listen to him, and those that don't will be punished. Even though Icefire is a very harsh leader, he is too powerful for anyone to try to stand up against him."
