Ultimate Battle Dragon (LEGO 71872)

About this set

LEGO 71872 Ultimate Battle Dragon sits in the NINJAGO line with a part count of 2178 and a difficulty of 4/5, pitched as a fantasy dragon mech. The box carries the LEGO, NINJAGO LEGENDS, 71872 and NINJAGO markings, and the build itself is a dragon-form mech in gold, white, black, green and red. The gold spiked armor runs along the spine and limbs, while the translucent green wings catch light and give the model real presence on a shelf. The set includes minifigures, a display base and damaged-building accessories; the base lifts the dragon mech, the broken structure extends the scene, and the minifigures give a sense of scale. The tricky part is the four limbs and the wing connections: the gold spike pieces point in similar directions, so sort the left and right armor into pairs first, then work through torso, limbs and wings. The large translucent wings need the pins aligned before pressing down, so avoid repeated disassembly. At 2178 pieces and 4/5 difficulty this is not a first build; it suits experienced builders and NINJAGO fans who want a dragon mech with a display base.
