LEGO SET 71765 - Alternate build | Ninja Ultra Combo Mech

LEGO’s 71765-1 Ninja Ultra Combo Mech is already an impressive showcase of NINJAGO’s high-octane action—and yet it’s just the starting point. With its bold color palette, robust ball-joints, and an abundance of specialized elements, this set is a goldmine for creative builders looking to push the boundaries of mech design. Whether you’re dreaming up a sleek, stealthy “Snake APU Walker,” a frosty “Freezer” mech, or a dazzling “Lightning Streak” interceptor, the parts in 71765-1 can be reimagined in countless ways to suit any ninja-themed battlefield—or even venture beyond the NINJAGO universe entirely.

From heavily armored titans to agile, bladed acrobats, these alternate builds showcase how one parts pack can yield wildly different personalities. Think about integrating light bricks into a “Fireblade” warrior for dramatic underglow effects, or pairing “Earthbreaker” with Technic tracks for a full-tank transformation. You might even combine two alternates—imagine a “NUCM Remastered” frame armed with “Kai’s Ultra Combo” weaponry—to create your own signature Ultramech. Let these MOCs spark your imagination: the only limit is how far you can push your ninja instincts.
