A mech riding a dragon sounds like the kind of idea a seven-year-old scribbles in the margin of a notebook, and I mean that as the highest compliment.
This is comfortably the best Mech Rider set Ninjago has done, mostly because the mech and the dragon actually look like they belong together instead of one being an afterthought. It is a touch pricey for what you get, and a couple of the joints are stiffer than I'd like. But if you or the young builder in your life is following Dragons Rising, this one earns its shelf space.
Best for: Dragons Rising fans who want two toys in one and a proper poseable dragon
What it is
The pitch here is gloriously simple. Ninjago has given us mechs. It has given us dragons. It had never, until now, put a mech on the back of a dragon, and honestly I don't know why it took this long. The dragon is what got me first: movable wings, head, jaw, legs and a whippy tail, and it holds a fierce pose without flopping over. Then the mech clicks onto its back and the whole thing stands over seven inches tall as a single rider figure. That combine step is the heart of the set, and it lands. You get three toys really, the dragon on its own, the mech on its own, and the pair fused into one snarling centaur of a machine.
The catch
I'll be straight with you about the price, because that's the loudest thing in the room. Seventy-five dollars for 584 pieces is on the expensive side of the shelf, and the comment sections agree. One person put it well: the dragon looks very good, just not seventy-euro good. This is very much a set to catch on a sale, and Ninjago sets discount often enough that patience pays. The articulation is the other honest caveat. Rogue's mech has no wrist joint, so the sword sits at one fixed angle, and the dragon, for all its poseability, reads more like a living creature than the robot dragon the box keeps calling it. If you came for clever mechanised detail, that gap will nag at you.
Who it's for
So who does this actually suit? If there's a kid in your world following Dragons Rising season three, this is close to an ideal pick, because it delivers the show's exact imagery and doubles as two separate play pieces before it becomes one big one. Collectors will care about Rox joining the ranks in minifigure form. If you're a strict value shopper counting pennies per piece, or you wanted a display piece with fussy engineering, wait for the discount or look elsewhere. For everyone in between, it's a genuinely fun build that photographs beautifully on a shelf.
The parts story
What the build is actually like, and the pieces worth knowing about.
The build moves at a nice clip, which is right for an eight-plus set. You construct the dragon and the mech as two distinct models, and both come together fast enough to keep a young builder hooked without feeling thin. The dragon is the more satisfying of the two to assemble, with the wing and tail sections giving you that lovely moment where a pile of parts suddenly becomes a creature. The mech is chunkier and quicker, and the payoff is the combine step at the very end where the two halves lock into one figure.
The standout piece is the soft plastic cloak that wraps the mech's shoulder, a lovely bit that catches an illusion of movement when you angle the model. Rox is the headline minifigure, a new member of the Forbidden Five, alongside Rogue, Arin and a Spectral Dragonian Warrior, and Arin's translucent reveal blade is the clever accessory here since it decodes a hidden message printed on the villains' banner. Nothing in the box is a brand-new mold showstopper, but the mix of printed pieces, the reveal gimmick and that flowing cloak element give the set more character than the part count alone suggests.
Fun facts
- 01This is the first time in Ninjago history that a mech rides a dragon, and it also includes the theme's first-ever robot dragon figure.
- 02The dragon's back is built to accept the mechs from Kai's Mech Storm Rider (71830) and Kai's Mech Rider EVO (71783), so owners of those sets can swap riders.
- 03Arin's reveal blade is a working play feature: hold it over the villains' banner and a secret message becomes readable.
- 04The set released on June 1, 2025 in most countries but did not reach the US until August 1, 2025.
