The LEGO Star Wars Master Builder Series (MBS) subtheme is an offshoot of the Ultimate Collector Series (UCS). While Ultimate Collector Series sets are more designed for adults and display, Master Builder Series sets are intended to be large direct-to-consumer sets aimed at both children and adults.
2020 LEGO Sets
In 2020, LEGO thrived despite global disruptions, debuting several new lines for both families and adult fans. LEGO Super Mario introduced interactive, course-building play; Monkie Kid launched with a modern take on Journey to the West; and creative-focused ranges such as DOTS, LEGO Art, and Brick Sketches broadened display and craft appeal. Creator Expert (later Icons) and Ideas delivered standout display sets, anchoring a strong year for collectors.
