The My LEGO Network BIONICLE Campaign was a series of tasks integrated into My LEGO Network, LEGO's kid-friendly social media site, that pertained to the events of the early part of BIONICLE story year 2009. In it, the user took on the role of a nameless Agori whose task was to form an alliance of characters from various tribes to fight the Skrall. These characters appeared as other users on the site with their own social media pages. The campaign is considered a canon part of the storyline, and the novel BIONICLE: Raid on Vulcanus briefly alludes to its events.
