"Kratana"

Kratana were mysterious creatures that had the power to see the future.

History
Two kratanas were mentioned in the Bionicle Adventures storyline. One attatched itself to Onewa near Makuta's lair, and the other one attacked Vakama while he was in Metru Nui and gave him a vision of Krakua. The one that attatched itself to Onewa was incinerated by Vakama, but the one on Vakama was pulled off by Makuta, and its fate remains unknown.

Little is known about when, why, and how these things came into existence. It is known, however, that Krana were not created from it, and Kraata weren't based off it. It is possible that they are the result of Brotherhood of Makuta experiments, as several dead specimens were found in the sea around the last reported location of Destral. Many of these mysteries will be revealed in BIONICLE Legends 10: Swamp of Secrets, when these creatures are to be explained.

Abilities and Traits
A "Kratana" looks like a cross between a Krana and a Kraata, having the long body of a Kraata and detailed ridge marks along its body like a Krana. It would affix itself to a being's face much like a Krana, although, unlike Krana, it could still attach itself even if the target was still wearing a mask.

The "Kratana" had the ability to give others visions of the future. How this works is unknown, although it is a natural power of the "Kratana."
