Which Lego theme is based on the world of spinjitzu and ninjas? Lego Ninjago is the answer.

Lego Ninjago launched in 2011 as a major original theme built around a team of teenage ninja heroes. Its fictional world combines ninja traditions with dragons, vehicles, futuristic machines, elemental powers, and supernatural villains. The characters train in Spinjitzu, a fictional martial art taught by the wise Master Wu.

The core group includes ninja such as Kai, Jay, Cole, Zane, Nya, and Lloyd, the Green Ninja. Each has a distinctive elemental association, while Lloyd becomes the central leader in much of the story. The theme was developed alongside an animated television series, creating an unusually extensive connection between toys, storytelling, books, games, and attractions.

Ninjago is sometimes confused with Lego Ninja, an earlier theme discontinued in 2000, or with Monkie Kid, another myth-inspired original line. Chima and Nexo Knights also feature fantasy heroes, but neither is the franchise defined by Spinjitzu and the Ninjago ninja team.
