Transformers Optimus Prime (LEGO 40803)

About this set

LEGO 40803 is a BrickHeadz take on Transformers' Optimus Prime, built from 237 pieces at a 3/5 difficulty. The finished model is instantly readable: a blocky head with a blue helmet and antennas, glowing blue eyes, a red chest plate with cyan windows, and a palette of blue, red, gray, white and yellow, all sitting on a black base. Before you start, sort the blue, red and gray parts by bag. The head antennas and the chest windows are the visual anchors, so take care with the small antenna pieces and the layer order of the windows against the chest plate to avoid rework. The black base is straightforward and can wait until the main body is done. The set's selling point is that it builds into either a truck or a robot, so decide which form you want on display before you commit. At 237 pieces this is a comfortable one- to two-hour build for anyone used to BrickHeadz clutch, and newcomers won't get stuck. It suits Transformers fans, BrickHeadz collectors, and anyone after a small display set for a desk; if you mainly want transformation play, this one leans static.
