Bronco is very much a replica of his father, Colt. He has a lovely, dense coat composed of rich, earthy tones and highlights of ochre when in direct sunlight. Like most, his markings darken on a gradient from his feet to his spine, fading from a dusty golden-beige along his underside and legs to a warm chocolate which coats his sides and darkens to a toneless black along his spine. Like most others in the Blackthorn family, he too sports a dorsal stripe which begins at a point above and between his eyes and trails down his spine to the tip of his brushlike tail.

His eyes are the shade of hot bourbon. He has numerous facial wounds, most notably two scars across the bridge of his muzzle from canine teeth, a missing left ear, and four parallel clawmarks across his temple from a cougar.

He has a large frame, but has recently lost a great deal of weight and muscle mass. His sides sink in around his hips, and his coat looks like it's two sizes too big for him.

In adolescence, Bronco had grown to surpass his expected physical bench-markers, but has not yet filled out the frame which promises a great deal of potential, if size were to be envied. At a glance, he appears big-boned with long, thick legs and and broad shoulders, but his frame makes him appear slightly short in the torso, given the fact he has inherited his father's body type- but also his mother's long legs. He has yet to build the musculature which will lend him strength and soften the angles of his joints, but his winter coat lends him some support, and in the spring he will likely shed out to reveal the toned muscles of an active wolf undergoing strength training.
