The Mask of Duplication was the Kanohi worn by Makuta Bitil. It allowed the wearer to summon a past version of themself to the present for help. The mask could summon dozens of the wearer's past versions, and was risky to use. If any of the user's past versions was killed, they would cease to exist in the past. When the mask was deactivated, the past versions were sent back to their time and their memories of the future erased. However, any damage to their bodies remained.

Trivia
