In the fictional Bionicle universe certain Matoran (workers and villagers) are destined to become Toa: heroic warriors of great strength and power. The Toa's duty is to protect the Matoran and maintain peace in the universe. They usually work together in teams, with each member representing an element. Each Toa has near-complete control over their element, and can access the powers of the more powerful Great Kanohi Masks. As the Bionicle universe is based around a line of action figures, most Toa have appeared in their action figure.
There were once as many as 3,000 Toa in existence, but after many wars, assassinations and murders, their numbers have diminished.
