Takutanuva (Earth-4001)

Takutanuva was the sentient being created when Takanuva and Teridax fell into a pool of Energized Protodermis and fused into a single entity, with Takanuva being in control of it. The entity's name was a portmanteau of the names "Takanuva" and "Makuta".

History
The history of Takutanuva is the same as his mainstream counterpart.

Personality & Traits
Being the perfect balance of light and shadow, Takutanuva was completely unbiased and did only what was best for the Great Spirit Mata Nui.

Powers & Equipment
Takutanuva was stronger than any other sentient being, though not as strong as Great Spirit Mata Nui. He had the powers of light and shadow, along with all 42 Rahkshi powers. He also had the ability to revive a lifeform by sacrificing some of his own life-force, something no other being in existence could do. He wore the Mask of Light and Shadow.

Trivia

 * Takutanuva's Mask of Light and Shadow appears differently for each version; in BIONICLE: Mask of Light, it is a half-Avohkii/half-Kraahkan; in BIONICLE: The Game, it appears like the Avohkii; in the comics (and on the set), it has the appearance of the Kraahkan.
 * In BIONICLE: Mask of Light, the rust and pitting on Teridax's armor and mask is mended when he becomes part of Takutanuva; this is manifested in the set by Makuta's gunmetal sections being replaced wih gleaming silver.
 * In the set and comics, Takutanuva carries a staff; in the movie and game, he doesn't.
 * Takanuva's Ussanui is used as part of the combination as the set, but it's not used in the combination in either the game or movie versions.
