Rahkshi

Rahkshi were a species of creatures made from Kraata. They were not living, but instead suits of armor controlled by the leech-like Kraata of their original form.

Overview
"Rahkshi - shadows that cower in the depths. Exactly as foretold."

When a Kraata was exposed to Energized Protodermis, it would die and mutates into inanimate Rahkshi armor. A second Kraata of the same power could then enter the armor and control it. A Rahkshi's power was at least equal to a Stage-6 Kraata's and likely even greater, though it was weakened when separated from the staff that it wielded.

When Rahkshi had no mission from a Makuta to fulfill, they acted as violent and dangerous beasts. But with direction and guidance from a Makuta, they had power enough to overtake even a Toa Nuva. Their violent nature made even Teridax reluctant to send them out, as he knew they would destroy anything in their path.

Just like Kraata, there were 42 types of Rahkshi. The best known of these (and the only ones named) were the six Teridax sent to find and take the Avohkii: Turahk, Guurahk, Lerahk, Panrahk, Vorahk, and Kurahk.

History
There were many Rahkshi in the city of Metru Nui. While searching for the Vahi, Teridax summoned every Rahkshi in the city to attack Voporak. While the entire army of Rahkshi was aged to the point of death by Voporak's time field, they caused the distraction needed for Teridax and Toa Vakama to slip away unnoticed. It was here that Vakama learned of the Rahkshi's connection to the Makuta. The Rahkshi are now terrorizing the Matoran Universe.
