Knuckles the Echidna is captured in a compact, stylized vinyl sculpture. The figure stands at about 90 millimeters tall, featuring Knuckles' signature red fur with a lighter chest area and peach-toned muzzle. Sculpted quills sweep back from the head, giving a bold silhouette. The character wears oversized white gloves with defined fingers and the classic knuckle detailing. The pose is dynamic yet balanced, suggesting readiness and strength, with one leg planted and a slight lean that conveys determination. The finish is clean and glossy, with crisp paint lines along the edges to emphasize the character's bold color contrast. Overall, it combines a cute, collectible charm with the recognizable features fans expect from Sonic's protector.

Knuckles the Echidna is the stoic guardian of the Master Emerald, entrusted with protecting it from those who would misuse its power. Raised on Angel Island by the echidna tribe, he embodies strength, determination, and a strong sense of duty. For years he has lived in isolation, focusing on his mission to safeguard the emerald and maintain balance in the island's ecosystem. Despite his stern exterior, he is brave, loyal, and quick to help friends when danger arises. He can glide short distances and climb surfaces, using his spikes as part of his fighting style. Over time, his path crosses Sonic the Hedgehog's adventures, testing their rivalry into friendship as both learn to respect each other's motives. Knuckles' role often centers on perseverance, guardianship, and the tension between tradition and curiosity.
