71851

LEGO Ninjago set 71851, Kai's Dragon Mech Battle Pack, depicts a dragon mech associated with Kai. Released in 2026, it contains 85 pieces and presents a compact Ninjago combat scene built around minifigures, ninja weapons and a small action model.

Kai's Dragon Mech Battle Pack belongs to the Ninjago theme and focuses on a small scale battle setup. Its main subject is Kai's dragon mech, a mechanical dragon inspired build that fits the theme's mixture of ninja action, elemental enemies and stylised character variants.

The set contains 85 pieces and 3 minifigures: Sora, Mask (Draconus Robes), Earth Monster and Kai (Draconus Form, No Wings or Tails). The French retail title also refers to katanas, so combat accessories can be noted without adding unsupported functions or play features.

This is best understood as a compact battle pack rather than a large display model. It supports quick play scenes, adds named characters to a Ninjago collection and can sit alongside larger sets from the same theme as a source of extra figures, an opponent and a small mech based build.
