Toa Tahu
Canisters containing the Toa washed up on the shores of Mata Nui. The Toa had almost no memory of their lives before arriving on Mata Nui.
Tahu is the fiercest of the six Toa, and the most feared--you don't want to get into a fight with Tahu if you can help it. He is most at home in the hot molten world of the Mangai Volcano where he surfs on lava flows, using his sword of flames to cut through rocks and keep the lava moving towards the ocean. His flaming temper can make him hotheaded and irrational sometimes. He has the least patience of the Toa and often jumps into a situation without thinking, which can get him, and the other Toa, into trouble!
The Toa have been mutated into Toa Nuva, and have since been on adventures to the island of Artakha. They are now in Karda Nui attempting to save the life of the Great Spirit Mata Nui.
