Scooter's Mysterious Prime Quick Review: Official Collaborations Never Stop! Following Strange Things, this time it's a completely unrelated Scooby-Doo collaboration, complete with the catchy name Mysterious Prime. The vehicle mode is a faithful recreation of the Mystery Machine from the show, featuring classic green, blue, and orange patterns. Unfortunately, the windshield isn't made of transparent material. The transformation mechanism is simple, with only basic articulation; its design can be described as lazy. The biggest highlight is its head-swapping mechanism. The four main character head sculpts are stored in a chest-mounted rotating disc, allowing for free transformation by opening the backpack—super fun, but with very obvious drawbacks. Aside from the unsightly mechanical faces, the inability to rotate the neck is a major flaw. Fortunately, the head-to-body connection point is the same as the official Headmaster from a few years ago, adding a bit of playability. Of course, we can't forget the Automutt mechanical dog. It's fun, but the design and structure are incredibly rudimentary. It lacks any articulation, and even when transformed into a snack box, it offers no interaction with the main body, which is truly disappointing. Compared to the previous Strange Things, it pales in comparison. Even when catching a deer, you need to know how to remove its antlers; I really hope the official team doesn't waste such a brilliant idea!
