Bionicle (stylized as BIONICLE) is a line of construction toys created by The Lego Group marketed primarily for 5-to-16-year-olds. Originally a sub-theme of Lego’s Technic series, the line was launched in 2000 in Europe and Australia and 2001 in North America. Over the following decade it became one of the Lego Group’s biggest-selling properties and played a part in saving the company from its financial crisis of the late 1990s. The theme was originally discontinued in 2010, but later relaunched in 2015 as a rebooted franchise.

To accompany the sets, Lego created an original story told on a vast multimedia scale that expanded as the theme continued. Set in a science fantasy universe featuring part-organic, part-mechanical beings, the story chronicles the tales of heroic beings called Toa in their fight against The Makuta – the arc antagonist – as well as the many other evils of their world in order to protect a widespread populace known as the Matoran. While the main story was told through common mediums including comic books, online games and animated films, a number of additional serials were incorporated into the saga that helped to expand it. A similar approach has also been adapted into the theme’s rebooted story.
