The verdict

The thing that won me over here is that the transformation isn't a cheap gimmick, it's a proper Technic-spined fold from a 24cm mech into a jet, and both modes hold up on the shelf.

You get five figures, two exclusive villains, a spectral dragon and Sora's flying bike, all for a price that quietly undercuts a lot of licensed sets with fewer bricks. It's aimed at kids nine and up but the engineering is grown-up enough to keep you interested. If you like sets that do two things well, this one's a genuine bargain.

The full review

What it is

Every so often a Ninjago set comes along that does more than pose on a shelf, and Lloyd's Jet Mech is one of them. This 1,112-piece LEGO® set headlines the 2025 Dragons Rising wave, and its whole reason for existing is the fold. You build a green-and-gold mech that stands about 24cm tall, twin greatswords in hand, and then you convert it into a sleek jet fighter. The clever bit is that this isn't a swap-the-parts cheat. There's a Technic spine running through the body that lets the arms, legs and cockpit rearrange into something that genuinely reads as an aircraft. One reviewer pointed out it scored higher than any of LEGO's official Transformers-branded transforming sets, which tells you the engineering here is the real draw, not an afterthought.

The catch

Now for the honest bits, because no set is perfect. The mech torso can look a little boxy from certain angles, and when it's in jet mode the underside shows some exposed structure that a display purist will notice. This is a play set first and a shelf piece second, so if you want flawless lines in both modes you'll spot the compromises. The age rating is 9+, and while an adult will breeze through the conversion, the transformation steps can get properly fiddly for younger hands the first few times. And because so much of the budget goes into making two models work, you won't find a wall of exotic new elements here, this is smart use of familiar parts rather than a parts-pack.

Who it's for

So who's going to love this one. If you're a Ninjago fan who wants a build that keeps giving after the box is empty, this is an easy yes. The five figures alone carry a lot of weight, and having two exclusive villains plus a dragon and a bike means the play scenarios basically write themselves. If you only ever build for static display and you want museum-accurate proportions, you might find the dual-mode compromises frustrating, and there are purer display mechs out there. But for value, versatility and the pure satisfaction of folding a robot into a jet on your desk, this is one of the strongest Ninjago sets of 2025, and I think it's worth every penny of the asking price.

The parts story

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

The build breaks into logical chunks, which is a relief given what it has to pull off. You construct the mech first as a complete model, then the instructions walk you through the conversion as its own clearly-signposted section, so you're never flipping back through the whole book trying to work out what moves where. The heart of it is a Technic frame, and there's a surprising amount of Technic construction tucked inside for a set that reads as a System build on the outside. That skeleton is what gives both modes their stability and lets the limbs pivot into place. Alongside the main model you build a poseable spectral dragon for the villains and a little flying bike for Sora, and both feel like proper side builds rather than filler to pad the piece count.

On the pieces themselves, the story is more about smart use than shelves of new molds. The armour plating is layered to hide the joints, and the twin greatswords are the standout accessory, they look great in the mech's hands and stow cleanly in jet mode. The real value sits in the minifigures. Five of them, and the two villains are exclusive to this set: Kur, the Master of Decay, and Spectral Dragonian General Tyr, joined by a Spectral Dragonian Warrior, with Lloyd and Sora in their current outfits. The prints are lovely, dual-sided heads and detailed torsos with good colour contrast. At 1,112 pieces for the price, the parts-per-dollar maths comes out ahead of a lot of licensed sets, which is a big part of why builders rate it so well.
