This is the Millennium Batwing created by amusered. It is an epic crossover between Lego, Star Wars, and Batman. Specifically, the red, black, and grey colors fit in with Batman Beyond. This is not a part swap build of the Lego Millennium Falcon, it is a wholly unique design. The biggest differences include the cockpit, and in the front the connected mandibles (is there a better term for those?). From design to the finished build the whole project took about a year. There is an incredible amount of greebling here. So many ports, grills, tubes, hoses, and transparent pieces. You can even find a pair of Lego keys. There is a furnished interior, but that will remain a mystery. I like to think that Batman spends some of his time playing chess. A question about this Batwing that comes to mind is… does Batman let Robin pilot?
