The Ultimate Collector's Series, or UCS, is a LEGO subtheme of Star Wars introduced in 2000 and was meant to be more detailed and aimed at older builders. These Ultimate Collector's Series sets tend to be larger, and more expensive than typical sets.
2006 LEGO Sets
2006 was a year of creative resurgence, adding major themes while closing older ones. LEGO Batman debuted as the first full DC Comics collaboration, joined by Avatar: The Last Airbender, Exo-Force, and SpongeBob SquarePants. LEGO Mindstorms NXT modernized the robotics platform with sensors and wireless control, and Remote Control Trains replaced the 9V system. Vikings and Clikits ended, while standout collector sets such as the Technic Tow Truck (8285) and Boeing 787 Dreamliner (10177) strengthened LEGO’s appeal among adult fans.
