In the BIONICLE reboot that started in 2015 and ran until 2016, one of the primary themes was the concept of 'Unity'. This idea was particularly prominent in the 2016 storyline. The theme of Unity was central to the Toa's quests and challenges in 2016, emphasizing collaboration, combined strength, and the idea that they were stronger together than they were individually.
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.
