Knox is a phoenix that dreams, as most fire elementals do, of becoming a star. Literally. He's generally quite friendly and loves his friends.

He can regenerate as long as his skull touches fire, and considering a phoenix bursts into flame upon their death this isn't usually a problem. However, if kept underwater until just his skull remains, he could theoretically be kept on someone's shelf as a trophy. Just be careful that one of his friends doesn't find out, because an unwary nemesis may find themself with a surprise case of arson and one less trophy skull.
