Hasbro has partnered with Warner Bros.' Scooby-Doo franchise on a new Transformers set called Mysterious Prime and Automutt, priced at $58 and available for pre-order on Hasbro Pulse, with shipments expected around September 1 Engadget.

Mysterious Prime converts from a robot mode into the Mystery Machine van, the franchise's signature psychedelic ride, while Automutt transforms from a box of Scooby Snacks. The set ships with four swappable heads for Mysterious Prime, each modeled on one of the human Mystery Inc. members — Fred, Velma, Daphne, and Shaggy — plus a small plastic camera accessory, a nod to the gang's amateur-detective toolkit Engadget.

The product listing on Hasbro Pulse confirms the same $58 price point and pre-order status as the Engadget report, with the two sources aligning on release timing and pricing Hasbro Pulse.

Mechanically, this is standard Hasbro crossover territory: a licensed IP mascot reskinned around Transformers' core conversion engineering, sold through the direct-to-consumer Pulse storefront rather than general retail at launch. The swappable-head gimmick is notable from an engineering standpoint — it lets a single figure body service four distinct "human" identities without requiring four separate toolings, a cost-efficient way to extend a crossover's perceived value without expanding the parts count materially.

This is not Hasbro's first foray into novelty licensed mashups for the Transformers line. The company has previously released NFL helmet-themed robots, an Evangelion-inspired crossover, and a World Cup soccer ball-shaped Transformer, according to Engadget's reporting Engadget. Scooby-Doo joins that lineage of oddball collaborations that trade on nostalgia recognition rather than narrative continuity with the core Transformers mythology.

The broader context here is a licensing strategy that has become fairly durable across the toy industry over the past decade: pairing a mature, high-recognition mechanical property like Transformers with equally durable but tonally unrelated franchises, betting that the novelty itself drives adult collector interest more than any attempt at internal lore consistency. Mysterious Prime and Automutt make no pretense of fitting into Cybertronian canon; the appeal is squarely the incongruity of a shapeshifting alien robot disguising itself as a cartoon mystery van.

Worth flagging: pricing at $58 for a two-figure set places this comfortably in premium collector territory rather than impulse-purchase toy-aisle pricing, consistent with Hasbro's recent pattern of positioning novelty crossovers as adult-collector items sold direct through Pulse ahead of any wider retail rollout. Whether that pricing holds if or when the set reaches mass retail remains an open question the current sources do not address.

For collectors and industry watchers, the September 1 shipment target sets this alongside Hasbro's broader fall product cadence, though no additional Scooby-Doo or Transformers crossover items have been confirmed alongside it based on currently available reporting.
