|Mask of Alternate Futures|
|Power(s)||Shows alternate timelines and potential futures|
|Notable Wearer(s)||Karzahni (formerly)|
The Kanohi Olisi is the only Great Mask of Alternate Futures created by the Great Beings. The Olisi gives its user the power to project an alternate timeline or a possible future into one or more being's minds. The user will also share in the vision. While the user can place a vision in a target's head and let it run on its own, this makes the vision easier to break out of.
- Karzahni used his Kanohi to show Jaller what would have happened if he hadn't saved Takua during the quest for the Toa of Light in BIONICLE Legends 2: Dark Destiny. Karzahni later used his mask to create a vision of what would happen if Mata Nui died.
- Karzahni also 'planted' an alternate timeline vision in Lesovikk's head. However, the Toa was able to break out of it after he realized it was false.
