Toa Nuva are a group of six heroic characters from the Bionicle universe, created by the LEGO Group. They are the evolved forms of the original Toa and possess enhanced powers and abilities. Each Toa Nuva represents a different elemental force: Tahu (fire), Gali (water), Lewa (air), Kopaka (ice), Pohatu (stone), and Onua (earth). The Toa Nuva were introduced in the 2002 storyline, where they must protect the island of Mata Nui from various threats. They wield powerful weapons called Kanohi, or masks, which grant them unique abilities. Their mission is to restore peace and balance to their world while battling the forces of evil.
