Lead the fight in LEGO Ninjago Kai's Source Dragon Battle (71815-1), a 120-piece set. It presents a red dragon model with a jaw, head, tail, legs, and four wings, all articulated for varied poses. Climber Kai, armed with a katana, confronts the Wolf Mask Guard, who carries a spear, and the Wolf Mask Warrior with their sword. Wyldfyre provides support with a second katana. The dragon's mouth holds a fire element for battle scenes. A shooter vehicle fires a large arrow into the skirmish, and a forest build includes a trap for characters. A Starter Brick piece provides a base, simplifying the dragon's initial assembly.
