An alaskan firedragon is a certain type of fire breathing dragon native to Alaska. Much like the sasquatch or big foot, loch ness monster and others, the dragon is claimed to exist by some, while others are skeptical.
Mike: Yo man, I saw an alaskan firedragon flying over Cook Inlet!
Jon: You sure you didn't smoke to much dope?
Mike: No, I swear to god I saw It!!
