Unity is a subtheme of Bionicle that consists of 3 sets that ran from 2015 to 2016. Most sets were released in 2016 which accounted for 2 sets. As of today, the average annual growth of sets in Bionicle Unity is approximately 13.3% per year.
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.
