Description
Two legendary warriors become one unstoppable force! The LEGO NINJAGO Rogue's Mech Dragon Rider (71843) building set lets builders 8 years old and up create the ultimate two-in-one warrior from NINJAGO Dragons Rising Season 3. This revolutionary set features both a fully posable warrior mech and the first-ever NINJAGO robotic dragon that can be enjoyed separately or combined by attaching the mech to the back of the dragon. The armored mech boasts movable arms and legs, an opening chest to place a minifigure inside, and battle sword, while the mechanical dragon dominates with a movable head, jaw, tail, legs, and wings, plus its own sword. Young commanders can stage epic battles with four minifigures: ninja warriors Rogue and Arin facing off against the villainous duo of Rox and a Spectral Dragonian Warrior. The secret banner holds hidden messages that only Arin can decode with his reveal blade accessory, adding layers of mystery to every adventure. Children can enjoy switching between solo mech battles and dragon flights, or the combined configuration as they recreate their favorite TV show moments or invent entirely new quests. Perfect for independent play or sharing epic showdowns with friends, this set makes an ideal birthday gift for NINJAGO Dragons Rising fans and kids who love mech and dragon toys. Kids can also attach the mechs from the Kai's Mech Storm Rider (71830) and Kai's Mech Rider EVO (71783) sets (each set sold separately) to the back of this set's dragon figure for expanded adventures. The LEGO Builder app guides young builders through intuitive step-by-step instructions with helpful 3D viewing tools. Contains 584 pieces.

Easy and Fun for All Ages!
[This review was collected as part of a promotion.] I asked my teenager to help me assemble this set, and even though it’s been at least seven years since they last touched Legos, they jumped right in and decided to make it a “speed run.” Two and a half hours later, we had a fully built set and a fun nostalgic experience together. They really appreciated the instruction manual with its clear visuals and accurate colors, and said the numbered bags made the pieces easy to find. All around, it was a 10/10 experience.

Lazy day must have
[This review was collected as part of a promotion.] I had a great time building this set!! Instructions were so easy to follow. I would definitely not build around smaller children as some of the pieces are really small.

Hours of fun!
[This review was collected as part of a promotion.] This set was my very first Lego build, and while it was a lot to take on with 583 pieces, it was absolutely worth it. The process kept me entertained for multiple hours (and even stretched over a couple of days), and I never felt bored while working on it. Each step gave me a sense of amazement and there’s a real feeling of accomplishment when you complete each section. The design is impressive and detailed, making the finished piece something I’m proud to display. For a beginner, it was definitely challenging, but that only made finishing it even more satisfying. Also there’s extra pieces too just incase. Overall, I’d recommend this to anyone—whether you’re new to Lego or already a fan—because the experience is both fun and rewarding.

Super fun to build
[This review was collected as part of a promotion.] I loved building this set the dragon is so cool. The paper building booklet was a little confusing then I remembered that there was the app and it helped me breeze through building the dragon and the other guy. I also loved the quality non brick pieces it didn’t feel like it was gonna rip apart in my hands.

Easy to follow instructions
[This review was collected as part of a promotion.] Lego lives in my house, they are in every room! This Nijda, This Rogues Mech Dragon Rider came with 5 bags of individual pieces. When put together, they form a specific part of the toy. My 8 and 11 year old sons had a great time putting this together. The instructions were easy to follow for both teams boys and it was completed in an hour. It looks so realistic and the colors are great.

Great size and even better entertainment!
[This review was collected as part of a promotion.] My son couldn’t wait to put this Lego set together. Assembly was easy with the directions provided. It is very durable once put together. Can be played with and doesn’t fall apart. The dragon is large in comparison to the smaller people which makes playing with it even more awesome! My son said this has been his favorite Lego that he has put together!

Ninjago or Ninjago…. either way it’s Legos baby!
[This review was collected as part of a promotion.] Legos! When I opened the box my baby grabbed it and took off running. She absolutely loves Legos and has since she could pick one up. Putting it together was quick for her and she even let me help. I love being able to spend time with her and Legos are always on the agenda. We enjoy the Ninjago series and this dragon did not disappoint. Awesome!!!

AMAZING final product, very unique
I loved building this set. As a long time ninjago fan, This set is one of my favorites. I went in with low expectations, but it ended up being my favorite set of the year. While not many are included for its price, the minifgures were amazing. The exclusive Rox is amazing, and I love the spectral dragonian.
