Engage in a thrilling confrontation from NINJAGO Dragons Rising season 3 with the LEGO Ninjago Rogue's Mech Dragon Rider (71843-1). This 584-piece set combines a formidable mech and the first-ever NINJAGO robot dragon, allowing for dynamic play or an impressive combined model. The mech features movable arms and legs, a chest that opens to house a minifigure pilot, and a powerful sword for battle. Meanwhile, the articulated dragon boasts movable wings, head, jaw, legs, and tail, ready to strike with its own blade, utilizing multiple ball joints for fluid posing. Four minifigures are included: ninja warriors Rogue and Arin, facing the villainous Rox and a Spectral Dragonian Warrior. The villains carry a banner with a secret message, revealed only by Arin’s specialized blade accessory. This unique set also enables expansion, with mechs from Kai's Mech Storm Rider or Kai's Mech Rider EVO attaching to the dragon's back.
