"Kratana"

Kratana were creatures that could see into the past and future.

History
The Kratana were created by the Order of Mata Nui.

One attached itself to Onewa near Teridax's lair, giving him a vision of the upcoming Visorak invasion, and the second attacked Vakama while he was in Metru Nui and gave him a vision of Krakua. The one that attached itself to Onewa was incinerated by Vakama, but the one on Vakama was pulled off by Teridax. Its fate remains unknown. The third was attached to Takanuva by Helryx and Krakua so he could see the Toa Nuva's past.

Abilities and Traits
Kratana looked a Krana and a Kraata combined. They had long bodies like Kraata and ridge marks on it's body like Krana. Kratana would attach themselves to the face or Kanohi of beings, then activate their ability of seeing the past or future. They also moved at fast speeds.
