The Vahki BIONICLE are robotic order enforcement squads designed by Nuparu to help keep the peace in Metru Nui, and were produced en masse by the city's Po-Matoran. They could transform from a biped to a quadruped state and were programmed with one directive to stop lawbreakers by any means.
The BIONICLE theme is series of sets based on modified TECHNIC pieces and ball-and-socket joints to create larger figures. Bionicles coincided with a series of comic books and graphic novels released during the set's run from 2001 to 2016. The theme was introduced in 2001 and originally discontinued in 2010, being succeeded by Hero Factory but additional sets were also released up until 2016 after it's break in 2010 to 2014. BIONICLE sets were tied together by an elaborate original storyline within the comic books and other multimedia that centered around bio-mechanical characters which are generally large, powerful beings that usually serve for good. The name BIONICLE is short for BIOlogical ChroNICLE.
