Our regular Optimus is a 2in1 build that can be assembled as the Optimus Prime Autobot or the usual rocking blue-red truck that Optimus uses to travel with the other Autobots. It's got 377 pieces and a very high level of detail.
Our other build is a classic/legacy Optimus Prime version composed of 384 pieces and it's also a 2n1 build.
A very rare addition to our compatilble lego Optimus Prime collection is the Optimus head. 1927 Pieces for a build that will amaze anybody noticing on your shelf or showcase.
