Mohtrek

The Kanohi Mohtrek was the Mask of Time Duplication, worn by Makuta Bitil. It allowed the wearer to summon past versions of themself to the present, and was risky to use. If any of the past selves were killed, the user would cease to exist. When the past versions were sent back to their time, their memories of the future were erased. However, any damage to their bodies remained.

Wearers

 * Makuta Bitil

Example Usage
Bitil used it against Onua to create an army of himself in Swamp of Secrets, thus making it harder to defeat him.

Trivia

 * The Mohtrek was not the kind of mask a Toa would wear, due to it having a power that a Toa would find immoral and it messed with the time frame.
 * Bitil thought of the mask as both a blessing and a curse - he got a completely loyal army of himself, but he'd also experience waking up with wounds he couldn't recall getting.
