LEGO Ninjago 71851-1 Kai's Dragon Mech Battle Pack presents Kai's Dragon Mech Battle Pack as a NINJAGO moment with action and story. Depending on the model, the appeal comes from ninja energy, dragons, mechs, temples or vehicles that suggest movement and conflict. That gives the set a clearer role within the NINJAGO world.
