Kai and Rapton's Temple Battle

Ninjago is an in-house LEGO action theme featuring martial artists and ninja warriors in a fantastical Asian-inspired world. Produced from 2011 onwards, the theme centers on a team of elemental ninja heroes and their ongoing battles against various antagonists. The theme is distinguished by its emphasis on detailed minifigure characters, colorful ninja costumes, and extensive worldbuilding through large modular city sets. It targets both children and adult collectors, combining accessible building with serialized storytelling adapted across television, films, and other media. The core cast includes ninja masters with elemental powers—fire, ice, earth, lightning, and others—who pilot mecha-style vehicles and fight threats ranging from skeleton warriors to supernatural enemies. Recent sets focus on constructing the fictional NINJAGO City, with modular buildings such as Markets, Gardens, and Workshops that form an interconnected urban environment. The theme explores recurring elements including temples, tournaments, and seasonal story arcs. Character designs emphasize ninja aesthetics with distinctive headwear and armor pieces unique to the theme's minifigure catalog.
