Transformers x Scooby-Doo Crossover Toy Set Drops Fall 2026

Hasbro is bringing together two legendary franchises with the Transformers x Scooby-Doo Mysterious Prime & Automutt action figure set. This unique crossover blends the transforming robots of Transformers with the mystery-solving charm of Scooby-Doo, creating a must-have for fans of either—or both—series.

What's Dropping

The set features two main figures: Mysterious Prime and Automutt. Mysterious Prime is a 6-inch figure that transforms from a robot into a Mystery Machine-inspired van in 19 steps. It also includes four interchangeable heads modeled after Scooby-Doo’s iconic characters: Shaggy, Fred, Daphne, and Velma. Automutt, on the other hand, transforms between a Scooby-Doo-like dog and a box of Scooby Snacks in just 6 steps. The set also comes with camera and flashlight accessories, adding to its playability and display value. Additionally, the set includes two ascots so Mysterious Prime can properly channel Fred or Daphne’s signature look. Mysterious Prime's interchangeable head sculpts incorporate character-specific details such as Fred's ascot and Velma's glasses, allowing the robot to represent different members of the animated cast.

When & Where

The Transformers x Scooby-Doo Mysterious Prime & Automutt set is available for pre-order now on Hasbro Pulse and Entertainment Earth. It’s set to officially release in September 2026 with a retail price of $57.99. Shipments are scheduled to begin around September 1, 2026. There’s no word yet on purchase limits, but given its collector appeal, it’s likely to sell out quickly once it hits shelves.

The Play

For collectors and fans, this set is a no-brainer. The crossover is a first for these franchises, making it a standout piece for anyone with a love for Transformers, Scooby-Doo, or both. Pre-ordering now ensures you’ll snag one before it potentially sells out. While it’s not explicitly marketed as a limited edition, its novelty and franchise appeal could make it a sought-after item in the future.

For resellers, the play is trickier. There’s no reliable eBay comp data yet, and the Fall 2026 release date means it’s a long-term hold. If you’re banking on flipping this, consider grabbing a few extras to hedge your bets. However, the real value here is likely in its collectibility rather than immediate resale potential.

Is It Worth It?

For collectors, absolutely. The Transformers x Scooby-Doo crossover is a unique blend of nostalgia and innovation, offering a fresh take on two beloved franchises. At $57.99, it’s priced competitively for a dual-figure set with transformation features and accessories.

For resellers, the verdict is less clear. While the novelty of the crossover could drive demand, the long lead time before release and lack of current resale data make it a speculative play. If you’re in it for the long haul, it might pay off, but don’t expect quick flips. For now, this one’s best suited for fans and collectors looking to add a standout piece to their shelves.
