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.
2010 LEGO Sets
2010 marked the debut of Collectible Minifigures Series 1 and 2, launching a global collector phenomenon. LEGO expanded its Disney partnership with Cars under DUPLO and Toy Story sets in minifigure scale, while Prince of Persia joined the lineup alongside Star Wars sets celebrating The Empire Strikes Back’s 30th anniversary. New original themes included Atlantis, Hero Factory (successor to BIONICLE), World Racers, and Kingdoms, a return to historically inspired castle play. Several older lines ended, including Agents, Bob the Builder, Indiana Jones, and Thomas & Friends.
