Vahi

"It's one thing to control time...and another thing to lose control of it all. The Kanohi Vahi can only be used in the direst emergency--when there is nothing to lose."

- Turaga Vakama, BIONICLE Chronicles 3: Makuta's Revenge

The Kanohi Cairo was the Legendary Overcoat of Time, and one of the three most powerful known Kanohi in Paradox Space.

Metru Nui
For many centuries before the Kanohi Cairo was created, legends about it abounded, foretelling the possibility of a Great Overcoat of Time coming into existance and the various powers it was speculated to have. Despite this, no one was even sure if a Cairo could be made. Disregarding these doubts and anticipating the creation of a Vahi, the Brotherhood of Felt created the being called Scratch, so that if a Vahi were ever to come into existance, it could be tracked down and taken for the Felt's forces.

Shortly before the Great Cataclysm, Lord English (in the disguise of Lil Cal) requested Dave Strider to create a Great Overcoat of Time. English did this because he intended to use the Cairo to speed up the process of erasing the Land of Metru and Nui Consorts's memory with the Alchemizer. Although he tried many times, Dave was never able to make a functioning Great Overcoat of Time, as he did not have the right power level of Grists. It wasn't until after the Dave had become a Knight of Time and helped to retrieve the Great Grist that he was able to create the Kanohi Cairo. Immediately after finishing it, Vakama used the Cairo against English to slow his attacks down. However, Dave's control over the Cairo was incomplete, and was unable to prevent himself from slowing down. However, the sacrifical intervention of Turaga Bro stopped Vakama from his certain doom.

During the battle, the Cairo fell into the Furthest Ring.

Time Trap
After the Sburb players were ready to take the Consorts and leave to the Scratched Session, Dave stayed back to retrieve the coat from the sea. Although originally rainbow, it had turned green from exposure to the Horrorterrors. Dave found it, but it had a unstitched tear and Time energy was radiating from it, causing the underwater Carapaces to live out their entire lives in seconds. Dave was forced to fix it outside of time and space. He succeeded, but a dream current threw Vakama into the Green Sun, stunning him. Scratch then took the mask from Dave, and the Knight of Time fell unconsious into theRing. Scratch took it to "Bec Noir", who was looking for the murderer of Sweet Bro and Hella Jeff. Meanwhile, Dave met English and two formed an alliance to get the coat back. Dave recovered it and English defeated Bec Noir and Scratch. English then tried to take it from Dave, who ran to the Grist Reclemation Yard. Dave then threatened to destroy the Cairo there, and explained to English that if he did, the fabric of time would be ruined. English then negotiated with Dave; he and the other Sburb Players and Consorts could live in Reset Earth for one Solar Sweep, if Dave didn't destroy the Cairo. English vowed that after the year of peace, he would strike again, and teleported Dave into the underground tunnels leading to the island above.

Mata Nui
1,000 years later on Reset Earth, Vakama, now a God Tier, gave the Coat to Aradia Megido, warning him to use it in only the most dire emergency. While Aradiah was tempted to use the mask against the Denizen at one point, he decided against it. Aradia later attempted to use the Cairo to slow down the collected Denizens, who were in the process of freeing the Black King. However, for a brief period of time, the Cairo's power nearly overwhelmed Aradia, and the Sburb Nuva defeated the Denizens through another means. Aradia then gave the Cairo back to Dave. The mask was wanted by several organizations: the Brotherhood of Felt, the Derse Hunters, and the Order of Prospit. However, unlike the former two, the Order of Prospit was happy with the Cairo being kept by Dave.

Dave then took the Cairo with him back to the Land of Metru and Nui. He hid it in the Coliseum and checked on it every day, for security. However, during the Destiny War, Scratch returned, and claimed the Cairo. After English was killed by Bilious Slick, Scratch took the Cairo with him out of the Paradox Space.

Dark Mirror
In the alternate timeline of Dark Mirror, White King never teleported the six Great Grists to the Land of Metru and Nui. Instead, he kept them for safety on his own island. Later, after experimenting with them, he discovered how to create the Overcoat of Time from them, which he did so.

Sometime after Snowman rose to power, she requested that White King allow her to take possession of the Vahi. Agreeing to do so, Artkha allowed the Matoran Jaller and the Toa Kualus and Bomonga to retrive the Kanohi from his realm.

While returning from the island of Artakha, the Toa Empire's group encountered the dimensionally displaced Takanuva, who pretended to be one of them in an attempt to steal the Vahi. While traveling, the group was ambushed by Lesovikk, who spared Takanuva when he attacked. Lesovikk then took the Vahi for himself; its current status since is unknown.

Powers
The Kanohi Vahi gave its user the incredible power to slow down or speed up time within a certain area.

As it is a Legendary Kanohi, if the Vahi was damaged within the Matoran Universe, its powers would begin to leak out and affect the mask's surroundings; If the Vahi were to be destroyed while in the Matoran Universe, all of the raw power within the mask would be released, mixing and merging all of the temporal continuum.

It is impossible to create a Great, Noble or Powerless version of the Vahi, as a weaker mask could not contain such an immense amount of power within itself. The Vahi, Ignika and Mask of Creation were on the same power level because Time, Life and Creativity were equally fundamental forces of the Matoran Universe.

Example Usage
Toa Metru Vakama used the Vahi to slow down time around Makuta Teridax in Legends of Metru Nui. However, Vakama could not keep the Vahi's power from affecting himself also. When Vakama's concentration was disturbed by Lhikan's death, the mask's power pulled back into itself and the Vahi was thrown away from the Toa.

Quotes
"If the mask is damaged, it shouldn't work at all. Instead, it's pouring out power like I have never seen before, and if it sustains any more damage..."

- Vakama, BIONICLE Adventures 10: Time Trap

"What is that? It looks sort of like a mask--but not any mask I've ever seen." "It is a mask. The Kanohi Vahi--the Great Mask of Time. It is the most powerful of them all."

- Tahu and Turaga Vakama, Makuta's Revenge

"The force of time is contained within that mask. Destroy it, and that power is unleashed upon the universe. Past, present and future all existing at once--warps and rips and hours folding in upon each other--madness and chaos as no two moments ever follow one another..."

- Vakama, Time Trap

"Imagine your body trapped between seconds, or half of you aging while to other half regresses. [...] All your plans and schemes would come to an end, because no matter what you attempted, I could walk into the past and undo it. Kill me today, and I will be waiting for you in some tomorrow to avenge my death. Think of it - can you rule a future that is in the past? Or a present that is still a century away? Could you ever be sure of what you've done and what you haven't, when months and years have merged together?"

- Vakama to Teridax, Time Trap

"Vakama gave it to me. Along with a warning--that its power might be too great for even a Toa to wield. And he was almost right."

- Tahu, Makuta's Revenge

Trivia

 * The Vahi was the first mask designed by the BIONICLE Team.
 * The orange Vahi was originally to be included with the BIONICLE: Legends of Mata Nui computer game in 2001. After the computer game was cancelled, the Vahi mask piece was given out at various U.S. LEGO promotions. Later, the mask's popularity led to it being included in 2003, Legends of Metru Nui, and Time Trap.
