LEGO’s 2022 Icons release of Set 10302-1 Optimus Prime isn’t just a display-worthy homage to the leader of the Autobots—it’s also a treasure trove of parts that invite builders to reimagine this iconic robot in wildly different ways. From sleek vehicle adaptations to detailed character busts, the set’s limited palette of specialized elements becomes the creative springboard for MOC designers around the world. By exploring these Alternate Builds, you’ll discover how a single set can yield everything from nostalgia-tinged tributes to entirely new Transformers interpretations.

Whether you’re drawn to the yellow-and-black flair of Bumblebee, the cinematic realism of movie-accurate busts, or even a prehistoric twist with a T-rex makeover, each model demonstrates how thoughtful part reuse can unlock surprising possibilities. These creations also offer a hands-on lesson in color blocking, structural ingenuity, and thematic storytelling—skills that translate to any MOC project you tackle next.
