The Sonic the Hedgehog brand has more reasons to celebrate after the spin-off series Knuckles debuted on Paramount+. Following the release of two very successful theatrical films, the character was spun off for his own series after making his big-screen debut in the sequel. It has already proven to be a big hit for the streaming platform. Per a press release from Paramount, Knuckles was streamed more than 4 million hours for its debut. This makes it the most-watched original series on the platform of all time.
