Overview

Take to the skies with the LEGO NINJAGO Ninja Dragon Riyu's Battle set (71855). Designed for kids 7 years and up, this dragon toy invites hands-on building, imaginative flight, and high-energy pretend play that echoes the action of your favorite ninja adventures. The dragon is built to move, with joints that respond to careful posing, helping young builders recreate dramatic showdowns and bold missions from the world of NINJAGO Dragons Rising.

What makes this dragon special

The Riyu dragon isn’t just visually striking; it’s crafted for dynamic posing. Builders can articulate the wings, legs, feet, arms, wrists, claws, head, tail, and shoulders to stage a variety of battle poses. The large sword and shuriken accessories add authentic weapon options that spark creative play and storytelling.

  • POSEABLE DRAGON TOY: Wings, legs, tail, and more move for dramatic flight and combat poses.
  • ACCESSORIES INCLUDED: A large sword and shuriken let kids arm the dragon for action scenes.

Minifigures and storytelling

The set includes four minifigures—ninja Arin and dragon-form Nya, plus the villains Mutation Monster and Loyalist—giving kids quick-good vs-evil storytelling opportunities. These characters open up a range of pretend-play scenarios as kids imagine brave rescues or epic duels.

  • FOUR MINIFIGURES: Ninja Arin, dragon-form Nya, Mutation Monster, and Loyalist for classic good vs. evil play.
  • INTERCHANGEABLE SCENARIOS: Swap weapons with the Cole's Mission Mech & Dragon Zane (71854) set for new battles (sold separately).

Play ideas and expansion

Kids can re-create moments from Season 4 of NINJAGO Dragons Rising or craft entirely new adventures. The dragon complements other sets in the line, enabling expanded battles and collaborative play with friends. A quick mix-and-match approach keeps storytelling fresh while building confidence in creative play.

  • EXPANDABLE BATTLES: Pair with related sets for larger, collaborative scenes.
  • FAMILIAR THEME, NEW STORIES: Reimagine scenes from the TV show or invent fresh missions.

Build, app, and display

With 347 pieces, this build offers satisfying hands-on assembly and a rewarding sense of accomplishment when the dragon comes to life. The LEGO Builder app adds digital tools to save progress, zoom in, rotate models, and explore 3D instructions—great for independent builders and group play alike. The dragon measures over 5.5 in. (14 cm) high, 13.5 in. (34 cm) long, and 13.5 in. (34 cm) wide, providing a bold display piece once the battle is complete.
