Fan CastingSonic: Lost World

Description of Knuckles the Echidna (Voice Role):

A loner by nature, Knuckles is independent, headstrong and serious, yet gullible and short-tempered to a fault. He is entirely devoted to his duty, spending most of his time on Angel Island protecting the Master Emerald, and rarely cares for anything that is of no importance. When his friends and others are in need of his help, however, Knuckles can always be relied on being willing to leave his post and prove himself a faithful and good-hearted hero. He is also one of Sonic the Hedgehog's oldest friends and rivals. Though usually depicted as the guardian of the Master Emerald, he was originally described as the guardian of Angel Island's seven Chaos Emeralds.
