Ryder is noticeably taller than Teddy, at 5"9 and he weighs 151 lbs. Ryder has jet-black hair, which naturally sticks up the way it does. Because of his Valerionite blood, Ryder's hair has a strong resistance to gel, so even maximum-strength gel cannot keep Ryder's hair slicked back at all. Ryder has brown eyes. Ryder, much like Teddy, gets criticism on his rather unruly hair from the adult humans but humans Teddy's age think his hair is cool-looking.
