Sonic Is Getting a New Netflix Animated Series — And It Isn't Sonic Prime Season 4

Sonic the Hedgehog is getting a brand-new Netflix animated series. Before anything else: this is not Sonic Prime Season 4, and Netflix and SEGA haven’t presented it as one.

What was actually announced

Netflix and SEGA announced, September 14, 2026, that a new Sonic the Hedgehog animated series is in development, alongside two other SEGA adaptations at Netflix — a Crazy Taxi theatrical film and a live-action Stranger Than Heaven film. The Sonic project is the one that matters most to fans of the franchise’s screen output, and it’s a genuinely distinct show, not an extension of anything currently airing.

The official description: “a high-voltage, comedic, yet emotionally grounded series built for kids who want to feel a little edge, a little attitude, and a lot of ‘that’s my crew’ wish fulfillment.” It’s aimed at an upper-preschool audience — younger than Sonic Prime’s target demographic — with Sonic and friends presented as heroes.

Is this Sonic Prime Season 4?

No — and here’s the evidence for that, since Netflix and SEGA’s announcement doesn’t address Sonic Prime directly one way or the other. Sonic Prime ran three seasons on Netflix and was, by the reporting around this new deal, considered a success. This new series has a different, specifically younger target audience, a different tone as described in Netflix and SEGA’s own language, and no mention anywhere in the announcement of Prime’s cast, its multiverse premise, or any continuation of its story. Nothing officially says “this replaces Prime” or “this is Prime’s next chapter” — it’s simply being introduced as a new, separate project, and treating it as a fourth season would be reading in a connection nobody has actually made.

One real thread does connect the two: Toru Nakahara, one of the two people confirmed developing this new series (alongside Carlos Stevens), previously produced Sonic Prime itself, as well as Paramount’s live-action Sonic the Hedgehog films and Knuckles. That’s continuity of a key creative figure across Sonic’s screen projects — not continuity of story or characters between this show and any of them.

What remains unknown

Netflix and SEGA have not announced: an official title for the series, a release date or window, an animation studio, a showrunner beyond Stevens and Nakahara’s development credit, a voice cast, an episode count, or which specific characters beyond Sonic himself will appear. Don’t treat any of those as settled until Netflix or SEGA say so directly.

How this differs from Memories and Beyond

Sonic the Hedgehog: Memories and Beyond is a separate, roughly 10-minute animated short SEGA is releasing to mark the franchise’s 35th anniversary, produced by Studio Giggex and distributed through SEGA’s own channels rather than Netflix. It features Sonic, Tails, Knuckles, Amy, Shadow and Rouge facing off against an upgraded Metal Sonic, and it’s not part of this new Netflix deal at all — different studio, different distributor, different purpose (a one-off anniversary celebration versus an ongoing series).

Where this sits beside the Paramount movies

Paramount’s live-action Sonic the Hedgehog film franchise is its own separate continuity, with its own cast and story, currently including a fourth installment in the works. Nakahara’s involvement in both that franchise and this new animated series doesn’t indicate any shared continuity between them — Netflix and SEGA’s announcement describes this as an animated television project, distinct from the live-action films in medium, audience and (as far as anything confirmed shows) story.

The bottom line

A new Sonic animated series is real and in development at Netflix, aimed at younger viewers than Sonic Prime ever was, with one familiar producer attached and almost everything else — title, date, cast, story — still ahead of it. It’s a new chapter in Sonic’s screen presence, not a continuation of the one currently on Netflix.
