Rogue's Mech Dragon Rider

The LEGO® Rogue's Mech Dragon Rider (set 71843) is a 584-piece LEGO Ninjago set released in 2025, recreating scenes from Season 3 of NINJAGO Dragons Rising. The set splits into two playable toys: a posable mech with movable arms and legs, an opening chest for a minifigure pilot, and a sword, plus the first-ever NINJAGO robot dragon with movable wings, head, jaw, legs, tail, and its own sword. Combine them and the mech mounts on the dragon's back to form Rogue's Mech Dragon Rider. Four minifigures join: ninja warriors Rogue and Arin, plus villains Rox and a Spectral Dragonian Warrior carrying a banner with a secret message readable only via Arin's reveal blade. The first robotic NINJAGO dragon plus a hidden-message reveal mechanic make this one of the most novel mech-dragon mashups in the Ninjago line.
