Phoenix

Phoenix
The Phoenix is a creature of unknown properties that may have been alive since the age of the dinosaurs. It was once theorized the Phoenix is immortal, but this was only proven false by Daniel's team as they had fought and killed the Phoenix. It is unknown if there is only one Phoenix, or if there was once multiple Phoenixes. There may be different Elemental Phoenixes, for Paige Chamberlain was possessed by a Wind Phoenix shortly before it vacated her body. Although the Phoenix cannot age, it is not indestructible. It can die, but a Phoenix can and will reincarnate itself if it so chooses. The Phoenix is capable of unimaginable destruction, and if kept unchecked, can put the whole world at risk.
