The verdict

I love that this one refuses to sit still on the shelf as just a cute head and torso, it actually reconfigures from a stout BrickHeadz robot into a squat tank, and getting that transformation to click into place the first time gave me a genuine little thrill.

It is not a deep build at 224 pieces, and if you came from the LEGO Technic or UCS side of Transformers you will find the tank mode charmingly simplified rather than mechanically clever. But as a desk-sized nod to a character this iconic, following on from the Optimus Prime and Bumblebee BrickHeadz pair, it earns its spot. This is a quick, satisfying build for a Transformers fan or a BrickHeadz completist, not a project for someone chasing an afternoon of engineering puzzles.

Best for: Transformers fans and BrickHeadz collectors who want a fast, characterful build rather than a technical challenge

The full review

What it is

I will admit I went in expecting a standard BrickHeadz brick with a big head and a smug little face, and instead I got a Decepticon who actually does something. Megatron here builds up first as the familiar squat robot silhouette, then breaks down and folds into a tank body, which is the whole reason this set exists instead of just being another static figure on the shelf. The first time the tread pieces locked into place under him I actually said out loud, that's clever, because BrickHeadz sets almost never ask you to think about mechanism, they ask you to think about color blocking.

The catch

I want to be honest about where this sits though. 224 pieces goes fast, this is closer to a coffee-break build than a weekend project, and the transformation, while satisfying, is simple by design, there is no ratchet or complex linkage under there, just smart part choice. If you are coming to this from Transformers Technic sets or the bigger licensed builds, the tank mode will look more like a toy tank than a faithful G1 gun-mode homage, and that is a fair thing to be disappointed by if screen accuracy is what you care about.

Who it's for

Where this earns its keep is as a companion piece. It follows the Optimus Prime and Bumblebee BrickHeadz duo from last year, and if you already have those on a shelf, Megatron completes a rivalry display that actually means something. Pick this one up if you love the characters and want a fast, fun build with a neat trick in it. Skip it if you are chasing part count, printed pieces, or engineering depth, because at this size and price point, none of that is really on offer.

The parts story

What the build is actually like, and the pieces worth knowing about.

Building it feels quick and cheerful rather than technical. You put together the familiar BrickHeadz cube body and blocky head first, in Megatron's grey and purple Decepticon colors, and then the set walks you into breaking sections back down and reassembling them into the tank hull. It is the kind of sequence that rewards a builder for paying attention rather than fighting with tiny clutch-power pieces, which makes it a genuinely good pick for a younger or newer builder working alongside someone more experienced.

There is not a deep well of rare or new-mold parts here since BrickHeadz sets lean on the same core brick and headpiece system across the whole theme, so the standout is really the transformation logic itself, how a handful of hinge and slope pieces get reused across both modes to make the tank read clearly as a tank and the robot read clearly as Megatron. There are no minifigures and no printed extras riding along, so the part-count value is modest, you are paying for the character and the trick, not for a haul of useful spare parts.

Fun facts

01Megatron follows the LEGO BrickHeadz Optimus Prime and Bumblebee two-pack released in March 2025, extending the Transformers BrickHeadz line into its Decepticon side
02The set includes a display stand alongside the two buildable configurations, robot and vehicle
03It carries a recommended age of 10 plus and a retail price around 19.99 pounds or 24.99 dollars
04Unlike most BrickHeadz sets, which are single static figures, this one is built specifically around a physical transformation between two forms rather than just a pose
