Flinx is a member of the Phoenix Tribe, and will appear as a minifigure in Summer of 2014. He appears to be a child because of his short legs.
He is the son of Fluminox, thus making him Prince of the Pheonix Tribe. It is unknown if he was born before or after, Sir Fangar and the Ice Clan was frozen. He is under-estimated by many to be weak, as he is a child. In The Heart of Cavora he becomes the 9th phoenix in The Great Illumination.
