The Oni Chopper is the reason to own this one, and honestly it won me over faster than I expected.
It is long and mean and stuffed with saw blades and hidden skateboards, and the build is a proper mix of Technic and System that never got dull. The Samurai X Mech next to it is the weak sibling, all stubby arms and odd legs, so you are really buying a great vehicle plus a rough one. But the figure lineup, especially Killow, has turned this into a small collector legend.
Best for: Sons of Garmadon fans and figure collectors who want the exclusive Killow
What it is
This is the set where Killow rides in on a chopper that looks like it was welded together out of every bad idea a villain ever had, and I mean that as the highest compliment. The Oni Chopper is long, low, and bristling with weaponry, from the spinning saw blade where a front wheel should be to the flip-out blades along the sides. It is built across bags three and four in a satisfying run of steps, and it uses parts in ways that made me grin, including paint roller handles standing in for the handlebar grips. Set beside it is the Samurai X Mech, and I will be honest with you, the mech is where my enthusiasm cooled. It has a nice opening cockpit and posable limbs, but the stubby arms and slightly off legs mean it never looks quite right no matter how you pose it.
The catch
So the caveat is a real one. You are buying one build you will love and one you will tolerate, and the box price of 49.99 dollars felt a touch steep for 556 pieces even back in 2018. A chunk of that budget clearly went into the figures rather than the brick count. The mech in particular is the sort of thing that reviewers at the time called one of the weaker Ninjago builds, and I do not disagree. If your heart is set on two showpieces of equal quality, this is not the balanced pairing you are hoping for. The chopper carries the whole set on its spiked shoulders.
Who it's for
Where this one earns its keep is the figures and the rarity. The set includes Resistance Jay, Samurai X, and the Killow big figure, and Killow appears in this set and nowhere else, which makes him one of the rarest characters in the entire Ninjago run. Resistance Jay is exclusive here too. That combination is exactly why the set has climbed so hard in value since it retired at the end of 2018, with sealed copies now trading for several times the old retail. If you love the Sons of Garmadon storyline, or you collect Ninjago figures and want the hard-to-find ones, this is an easy yes. If you only care about display-quality builds and you are cost conscious, the mech and the resale premium make it much harder to recommend.
The parts story
What the build is actually like, and the pieces worth knowing about.
The chopper is the part of this box that actually feels like a build rather than an assembly. It comes together over 112 steps that blend Technic framing with regular System bricks, so you get real structure under the plating and a bike that holds its shape when you swoosh it. There is proper problem-solving in how the long body and the front blade assembly lock together, and the play features get worked in as you go rather than tacked on at the end. The mech, by contrast, is a quicker and less rewarding sit, which is a big reason the two halves of the box feel so uneven.
For parts hunters the highlights are more about rarity than new molds. Killow himself is the standout inclusion, a single-set big figure carrying the Oni Mask of Deception, and pulling him out of the bag is a small event. The paint roller handles used as handlebar grips are the clever alternate-use piece everyone points to, and the saw blade mounted as a front wheel is a satisfying visual trick. Add the printed Oni mask element, the booster pack with its stud shooters, and two exclusive minifigures, and the value of this set lives in specific pieces rather than in sheer quantity.
