Looks like nostalgia’s back on the menu, boys! Standing over 13.5″ tall and fully capable of transforming back and forth between robot and semi truck modes without disassembly, this Optimus Prime LEGO model kit is the stuff our childhood dreams were made of.

The set clocks in at 1,508 pieces and includes accessories that any diehard Transformers fan will recognize, like Optimus’ ion blaster, Energon axe, an attachable jetpack, and even the Matrix of Leadership that resides within the robot’s opening chest.

Speaking as someone who grew up watching the original ’80s cartoon, this is one of the coolest LEGO sets I’ve ever seen, and I’ve had the opportunity to write about lots of great ones.
