LEGO Rogue vs. Drix Race Car Duel 71840

Two LEGO Ninjago race cars, one red and black with Rogue minifigure, one blue and gold with a ninja minifigure, in a dynamic battle pose. Another ninja minifigure is next to the blue car with two golden swords.

High-Octane Dragons Rising

This scene immediately plunges us into the heart of a Ninjago showdown! Rogue's dark, aggressive vehicle, sporting sharp fins and a massive blade, looks ready to slice through the competition. The blue racer, piloted by the Golden Ninja, counters with a more aerodynamic build, equipped with powerful stud-shooters. Nya stands ready with her swords, adding another layer of action to this epic confrontation.
