A set this perfect rarely comes along, maybe every 4-5 years, but nonetheless the Nindroid Mech Dragon is one of those special sets that manages to perfectly capture the imagination of a child and make a collectors dream come true. Its got the best minifigures in the line so far, with two amazing exclusives, Sensei Garmadon and Evil Wu. Its filled with all kinds of goodies from minifig accessories like weapons and gliders to spinning blade functions, its all around awesomeness. What most impressed me though was how well the functions were incorporated into the Mech Dragon and buggy without creating structure issues. Another astonishing improvement in this set is the remarkable structure of both the buggy and Mech, of which will not only hold its own in tough play but also pass the test of time. Its truly a great set and a must have. For children, its a guaranteed favorite and for collectors, its a jewel for display and a potential gold mine in value.
