About this item
Product details
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.

Great item, great brand. This brand is very good for my 5 year old grandson. It gave him a real boost in moral knowing he can do this himself with me just watching.

The set is amazing. It was easy to build and it is fun to play with. The design is really cool, it is a robot dragon. The set comes with Arin and Rogue. *review told to me by my son.
