LEGO NINJAGO Rogue’s Mech Dragon Rider (71843) – Two-in-One Mech and Robotic Dragon Play Set | 4 Minifigures | Ages 8+

Two-in-One Battle Experience

Discover a standout NINJAGO set that lets kids command both a posable armored mech and the first robotic dragon from Dragons Rising Season 3. The Rogue’s Mech Dragon Rider (71843) invites builders ages 8 and up to explore two distinct forms, or combine them for a dramatic Mech Dragon Rider setup. The mech features movable limbs and an opening chest to hold a minifigure, while the dragon offers a movable head, jaw, wings, legs, and tail, each ready for action-packed scenes. An accompanying dragon sword enhances the fantasy flavor of every skirmish.

With a total of 584 pieces, the model invites careful assembly and satisfying reveals as you unlock each section. The two-in-one premise encourages kids to switch between solo mech battles, dragon flights, or a fully blended Mech Dragon Rider, enabling a breadth of dialogue and storytelling possibilities without needing to purchase extra sets.

• Fully posable mech with moving arms and legs, plus an opening chest for on-board minifigures
• Mechanical dragon with movable head, jaw, wings, legs, and tail for dynamic flight sequences
• Includes four minifigures—Rogue, Arin, Rox, and a Spectral Dragonian Warrior for diverse battles

Playset Details and Experience

Standing over 7.5 in. (19 cm) tall, Rogue’s Mech Dragon Rider presents a bold presence on display or during imaginative duels. The dual-configuration design supports quick reconfigurations from battle-ready mech to soaring dragon, or the dramatic joined mode at will. This set is ideal for independent play sessions or shared adventures with friends, keeping the focus on creative exploration rather than a fixed outcome. While not a guaranteed result, the configuration options offer possibilities for memorable battles and story moments that align with a child’s own imagination.
