"Kratana"

"Kratana" are mysterious sentient beings that have the power to see the future.

History
Two kratanas were mentioned in the Bionicle Adventures storylines. One attatched itself to Onewa while he was in 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, 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 also not a parasite and it has not been revealed yet whether or not "Kratana" were experiments, or whether or not it has an affiliation, like the Kraata do. However, 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 affixes itself to a being's face much like a Krana does, although, unlike Krana, it can still attach itself even if the target is still wearing a mask.

The "Kratana" has the ability to give others visions of the future. It does so by attaching itself to their face or mask. How this works is unknown, although it is a natural power of the "Kratana."
