What sets the Optimus Prime apart from many other licensed kits of this size is that it’s highly interactive. Though you won’t be pulling off dynamic poses, you will be able to gently adjust the limbs of Optimus, equip him with his trademark ion blaster, and even replace his hand with his legendary Energon-Axe. Optimus has 19 points of articulation, so he’s essentially a large high-end action figure that doubles as an awesome display piece.

The real magic here is that Optimus can transform into his signature truck mode, easily shifting from Autobot commander to a big rig that’s ready to roll out. To get to that point is the fun part though. It took us just over three hours to piece together the 1,500-plus bricks needed to bring everyone’s Cybertronian to life.

Once you’re done, you’ll have an Optimus Prime replica that measures 13.5 inches tall in mech mode and 10.5 inches long when converted into a truck.

After two years of talking to himself and converting into a truck to take long aimless drives, one of Optimus Prime’s pals finally joined him in the brick-built world of Lego last summer.

Lego’s 950-piece Bumblebee kit has yet to receive a discount, but this comparatively smaller buildable figure is one of the coolest Lego sets under $100. It has numerous points of articulation, and you can quickly transform the Autobot from mech to car.

Bumblebee is 9.5 inches tall in mech mode and 8.5 inches long in vehicle mode.
