Pure Fire was a crow who enjoyed swearing and starting arguments, and spent most of his time pooing on other birds repeatedly without mercy. Most birds see him as a "jerk", but occassionally, others would join him in bullying other birds. He was also mostly seen in the cities, however, he is known to have appeared in the hills a few times, as well. He enjoyed ridiculing people and destroying nests and eggs.
He usually takes part in conversations that he has no business in and starts making sarcastic and/or inappropriate remarks, usually resulting in a full-fledged fight. He was seen doing this several times, before finally disappearing sometime prior to the islands.
It is unknown why or when he disappeared. Some have claimed to see him only very rarely, but he didn't respond to anything, which may suggest it's another "Pure Fire".
