LEGO NINJAGO Fire Knight Mech (71846) – 996-Piece Set for Teens 14+ | Kai Minifigure

Epic build, dynamic battles, and bold display

Unleash the legend of the Fire Knight Mech in a scene inspired by the NINJAGO Legends Monstrosity. This 996‑piece build centers on a towering armored warrior that rises from a coastal backdrop to confront a tentacled sea monster. Teens aged 14 and up can guide Kai—inside the mech’s chest chamber—through a dramatic clash, while a fisherman watches from a small boat nearby. When finished, the model doubles as a striking piece of teen room decor that can be reimagined for new adventures anytime.
