What Makes this set WOW?
Starter Brick system: A specially cast element of the mech's body and legs allows the youngest constructors to quickly build a stable figure without the help of adults.
Dynamic mech weapons: The model is equipped with a large golden sword and a functional, rotating saw blade on the arm, which allows you to recreate spectacular fight scenes from the series.
Combat glider with launcher: The set includes a flying vehicle for the Wolf Mask warrior with movable wings and a working disc shooter, which adds an element of skill to the game.
Crystal Artifact Cave: A separate structure with a hidden "Shatter Hammer" is a key plot element, giving ninja battles a specific mission objective.
