|Title||Mask of Time Duplication|
|Powers||Summons user's past selves|
The Kanohi Mohtrek is the Mask of Time Duplication. It allows its user to transport one or more past versions of themselves to the present. When these past selves are returned to their times, all memories of what they did are erased, but all physical damage they sustain is kept. If a past self is killed, the user will vanish, and an alternate timeline where they did not exist will be created. The amount of concentration required to keep the past selves in the present increases with the number summoned.
- Toa would not normally wear this mask because they feel its power is immoral, as it both upsets the timestream and is associated with the Makuta.
- Bitil considered his Mohtrek a curse as much as a blessing, as he often found himself with injuries at random times and without any memory of what happened, due to being part of future battles.
