Witness the clash with the LEGO NINJAGO The Fire Knight Mech (71846-1), a 997-piece display model from 2025. This detailed set depicts a dramatic confrontation: the cape-wearing Fire Knight Mech, armed with a spear, battles an ancient sea monster with movable tentacles emerging from the depths. The mech offers posable features, allowing for dynamic action poses to recreate scenes from the NINJAGO Legends Monstrosity series. It rests on a display base that can be removed for interactive play. Inside the mech's chest, the Kai minifigure, wielding his magical sword, stands ready, while a fisherman with a paddle steers his small boat nearby.

How these source sets were selected

NINJAGO catalog sets from 2011 onward, with standard five-digit set numbers ending in -1 and between one quarter and twice this set's catalog piece count (at least 50 pieces). Ranked by the number of exact shared pieces; ties favour higher source inventory coverage. This is a limited catalog comparison, not a claim about price, availability or the best set to buy.

Totals use inventory quantities, which can differ from the advertised box count. Snapshot: 2026-09-21. Original catalog colours are preserved. The source inventory contains 1,714 non-spare pieces; 11.4% are usable for this target. Inventory corrections after this date are not included.
