Knuckles[b] is an American television miniseries created by John Whittington and Toby Ascher for the streaming service Paramount+, based on characters from Sega's Sonic the Hedgehog video game series.

Production began in London, England, in April 2023, with Sonic film director Jeff Fowler directing the pilot and further casting announced.

Ged Wright, Brandon Trost, Jorma Taccone, and Carol Banker directed the following episodes.

[6] For the show's plot, the writers decided to reuse the buddy comedy approach from Sonic the Hedgehog (2020), which was favored by the crew.

Rather than having one of the characters serve as the straight man of the duo, the writers wanted both Knuckles and Wade to be "wildcards in a buddy comedy" due to its comedic potential.

[6] Additional cast members were confirmed, including Cary Elwes, Stockard Channing, Christopher Lloyd, Paul Scheer, and Rob Huebel in June 2023.

[8] In February 2024, it was announced that Ben Schwartz and Colleen O'Shaughnessey would reprise their roles as Sonic the Hedgehog and Miles "Tails" Prower in a guest star capacity.

[23] Visual effects providers for the series include Industrial Light & Magic, Fin Design,[13] Rising Sun Pictures, Outpost VFX, and Untold Studios.

[29] Ben Travis of Empire said, "It all looks suitably cartoonish fun, all anchored in Idris Elba’s gravelly vocals in the title role.

"[30] Charles Pulliam-Moore at The Verge commented on the series' six-episode length by saying that it "feels less like a full-on spinoff show and more like a solid chunk of storytelling meant to hold fans over,"  but added that its "brevity" and "flash action pieces" might make it a success.

The series' debut also had a positive effect on the other Sonic titles on the service, with viewership up 278% over the previous daily average.

The website's critics consensus reads, "Pairing Idris Elba's terse echidna with a befuddled Adam Pally, Knuckles could use some extra punch to appeal more broadly beyond youngsters but hits just fine as light family entertainment.

She commended the visuals, performances, comedy, and story and concluded her review by saying, "It's got some heart, too, which is always good, and unlike its prickly protagonist, it doesn't take itself too seriously.

He praised the performances of Elba and Pally as well as the chemistry between their characters, the action scenes, comedy, and use of licensed music, and wrote, "Knuckles is a fun, chaotic bonus level that nails everything that made the Sonic movies great, earning a well-deserved fist bump.

They wrote that while the series "functions largely as a streaming-only clone of the first film, it displays a personality missing from the mainline movies by veering into welcoming absurdism and whimsy.

They felt that lacking Jim Carrey from the Sonic films "to help carry the load" led to an inferior product with no discernible target audience in mind.

He similarly felt that the series failed to reach its full potential, directing criticism at the lack of focus on the title character and the uninteresting villains.
