Hasbro’s Transformers division has turned Optimus Prime into a teal and lime green dead ringer for the Mystery Machine, and given him a robot dog who folds down into an actual box of Scooby Snacks.
Images of the crossover leaked a full day via toy site TFW2005 ahead of Hasbro’s official reveal, and fans split on it fast. Some called it long overdue for the franchise, while others thought Scooby came out looking more like Muttley than Muttley does.
Meet Mysterious Prime and Automutt
Mysterious Prime is the headline figure here, a 6-inch robot that folds into a dead ringer for the Mystery Machine in 19 steps. He comes with four swappable heads modeled on Fred, Daphne, Velma, and Shaggy, along with a camera, a flashlight, an orange ascot for Fred, and a green one for Daphne.
Automutt, his sidekick, folds from full dog mode into an actual Scooby Snacks box in six steps.

The full set is expected to run $49.99 and go up for preorder through Hasbro Pulse and other retailers this week, with a release planned for Fall.
Based on the images, the set is teal and lime green from bumper to boots, and it wears Fred’s orange neckerchief like it was born with it on, though that still doesn’t explain why its best friend folds into a box of dog treats.
It slots neatly into a run of Hasbro’s other recent mashups, since the company already has a second wave of Transformers x NFL figures out, along with an Optimus Prime and Megatron pair pulled from 1984’s Transformers: The Movie.

Hasbro continues to expand its licensing efforts elsewhere too, from an AI studio built to let outside companies use Transformers and GI Joe characters, to an anime sending Scooby and Shaggy on a monster hunt through Japan.
