Autobots, roll out! Today we complete the full final assembly of the G1 Optimus Prime scale model. Chest and arms meet the body, the circuit board goes in, every cable gets plugged, the head is secured, trim pieces are glued, and the Matrix of Leadership is installed. We have a finished robot…and it looks amazing.

On the LEGO side, we kick off the jetpack build inspired by Sideswipe’s G1 jetpack from “More Than Meets the Eye, Part 3,” working through steps 379–395.
