LEGO 71731, Epic Battle Set - Zane vs. Nindroid, depicts a duel between Zane and a Nindroid in the Ninjago theme. Released in 2021, the set contains 66 pieces and 2 minifigures.

This set focuses on a compact confrontation between Zane and a Nindroid opponent. Within Ninjago, it is best understood as a character driven battle scene rather than a large vehicle, creature, or location model. Its subject is direct conflict, with the two included figures defining the scene.

The build provides a small setting for the duel and supports play around the two characters.

LEGO 71731 suits Ninjago fans who want a small battle setup or specific figures for a collection. It can be displayed as a compact combat vignette, or combined with other Ninjago sets to create a broader scene. Among sets from the same theme, it is a focused add on rather than a centerpiece.
