The verdict

This is the set that closes the loop, giving Kai and Nya the Titan Mech treatment so the classic team is finally whole.

Both figures stand over 10 inches tall and bend at nearly every joint you'd want, and Nya's mech in particular has articulation that put a grin on my face. At around 140 dollars for two builds you're paying for scale and poseability more than clever trickery, so go in wanting display pieces you can actually pose, not a puzzle-box build.

The full review

What it is

There's something satisfying about a set whose whole job is to finish a story, and that's exactly what this LEGO® set does. The Titan Mech collection started way back in 2015, and for years Kai and Nya were the ones left waiting while their teammates got the big poseable treatment. The Twin Titan Mechs fixes that in one box, handing you two 10-inch figures built in the style of Lloyd's 2026 Titan Mech (71860). Kai's is all fiery wrist blades and chunky knee armor, Nya's leans sleeker, and both of them bend at the head, neck, shoulders, knees, legs, and ankles. If you've been collecting these, this is the piece that lets you finally line the whole team up on a shelf, and honestly that moment is worth a lot.

The catch

Now for the honest bits. This is a 1,708-piece set that runs about 140 dollars, which lands in fine-not-generous territory once you realize a big chunk of those pieces go into bulking out two large frames rather than into fussy detail work. The bigger thing to know is that both mechs use the same underlying Lloyd Titan Mech template, so once you've built Kai's, Nya's follows a very familiar path. It's a comfortable, relaxing build the second time through, but it isn't going to surprise you. And for a set this size, three minifigs feels a touch thin. You get Pilot Kai, Pilot Nya, and a single Oni Warrior to fight, so the play scenario is really just two heroes versus one baddie unless you bring in figures from other boxes.

Who it's for

So who's this really for? If you're a Ninjago collector who has been chasing the Titan Mechs, this is an easy yes, because it's the set that completes the group and both figures display beautifully. If you love poseable action figures you can actually stage in a dramatic leap thanks to that included stand, you'll get a lot out of it too. The people I'd gently steer away are builders who live for engineering cleverness and novel techniques, because a second helping of the same mech template won't scratch that itch, and anyone who judges a set purely on minifig count will feel a little short-changed. But for what it sets out to do, giving Kai and Nya their due and letting the team stand together at last, it delivers.

The parts story

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

The build splits neatly into two halves, one mech each, and they share the same skeleton so the rhythm repeats. You start low, laying down chunky foot and ankle assemblies that give these tall figures a stable base, then work up through poseable legs and armored knees before framing out the torso and cockpit that actually holds a pilot minifig. The arms are where it gets fun, since they're built to swap, and Kai's wrist blades with their fiery detailing between the blades are the standout moment. It's a relaxed, forgiving build rather than a technical one, and because the second mech follows the first so closely, the back half moves quickly once the pattern clicks.

On pieces, this leans into large armor panels, ball-joint articulation elements, and the poseable frame parts that make the mechs stand and bend the way they do, all in Kai's warm reds and Nya's cooler scheme. The printed cockpit and detailing elements do a lot of the visual heavy lifting, and the interchangeable weapon and arm connections are the genuinely useful, reusable parts here. Value-wise, 1,708 pieces for roughly 140 dollars works out to a hair over eight cents a part, which is dead average for LEGO, so you're paying for scale and poseability rather than a bargain brick haul. It's a parts mix aimed at posing and display, not at stocking your spare-parts bin with rare recolors.

Fun facts

02This set exists mainly to complete the collection, since Kai and Nya were the last of the classic ninja team without their own Titan Mech.
03Both mechs are built in the style of Lloyd's 2026 Titan Mech (71860) and each stands over 10 inches (26 cm) tall.
04The Pilot Kai and Nya minifigs have swappable faces that turn them into Jin and Mira, two new characters from the Ninjago Legends: Duskfall storyline.
