2015 LEGO Sets
In 2015, LEGO broadened its portfolio with new and returning themes. LEGO Dimensions launched as a toys-to-life crossover linking dozens of franchises including DC, The Lord of the Rings, and Doctor Who. New lines such as Elves, Jurassic World, Scooby-Doo, and Speed Champions debuted, while BIONICLE and Pirates returned in refreshed forms. City marked ten years under its modern branding, and Star Wars supported The Force Awakens with a major release wave. Meanwhile, Teenage Mutant Ninja Turtles and The Hobbit concluded as LEGO shifted toward newer properties.
