Swaying, Snakelike Cats. Serpopards are 13 feet long and weigh 600 lb, with little gender dimorphism. They have feline bodies but long, serpentine necks topped by vaguely draconic heads. Their hairless paws have wickedly curved, retractable talons. A serpopard's neck is in constant motion, swaying like a cobra, allowing it to track foes on all sides and to strike in unexpected directions.
