Woptars serve as the primary mount in the Utawarerumono world instead of horses. They look similar to raptors, and their name is presumably a pun on the word 'raptor.' They are scaled with a cream underbelly, and most have a light green back. Other color variations do exist as Benawi has a Woptar with a white back he always rides, Kurou's has a dark green back, and King Orikakan rode one that was dark purple.
There appears to be a subspecies as the ones in the northern kingdoms are covered in feathers, presumably to keep warm.
