Transformers Boy's Converting Optimus Prime Costume

The Outfit With a Truck Hiding Inside

Is he a robot? Is he a truck? Is he somehow both at the same time? With this Boy’s Transformers Converting Optimus Prime Costume, your kid becomes the ultimate playground legend. This is no ordinary robot costume—it actually coverts. One minute he's a towering Autobot leader. The next? Full semi-truck mode on the sidewalk, blocking imaginary traffic and collecting imaginary tolls.

It’s the kind of costume that makes every other kid say, “Wait—your costume turns into a truck?!” And just like that, your little hero becomes the most powerful force in the neighborhood (with the aerodynamics of a foam rectangle).

Product Details

This officially licensed costume comes with a printed jumpsuit covered in detailed Optimus Prime graphics, closing with a hook-and-loop fastener at the back. Foam wrist cuffs and boot covers feature attached tires and slide on over shoes with an elastic band. For a snugger fit, have your kid wear their usual sneakers underneath. The gloves and molded plastic mask finish the look, with mesh-covered eye openings that limit peripheral vision, so keep an eye on your trick-or-treater when they're in full mask mode.

The real showstopper is the foam truck cab. Your child stands inside it, head through the roof, then crouches down for full truck mode, complete with a mesh "windshield." It's designed as a one-size-fits-most piece that sits over the shoulders rather than scaling with costume size, so it can run roomy even at the right jumpsuit size. Avoid packing it tightly in storage between wears to help it hold its shape.

Transform, Trick-or-Treat, Repeat

This Converting Optimus Prime costume is the ultimate fusion of dress-up and toy magic. No batteries. No apps. Just a jumpsuit, a mask, and a foam truck cab your kid can drop into and out of on their own, robot one minute, semi-truck the next, over and over all night long. Pure, glorious conversion powered by your child. Autobots? Roll out!
