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.
2012 LEGO Sets
2012 was a landmark year highlighted by LEGO’s 80th anniversary and major licensed expansions. LEGO The Lord of the Rings and The Hobbit joined the lineup alongside Marvel and DC Super Heroes, establishing enduring partnerships with both comic universes. LEGO Friends debuted, introducing mini-doll figures and Heartlake City, becoming one of LEGO’s most successful modern themes. Other launches included Monster Fighters, Disney Princess, and Dino. Alien Conquest, Atlantis, Pharaoh’s Quest, Kingdoms, and Harry Potter retired, though Harry Potter would later return in 2018.
