Lerahk

Lerahk were Rahkshi of Poison, and one of forty-two possible breeds of Rahkshi.

History
A Lerahk, along with a Guurahk and Panrahk, was created by Teridax to seek out the Avohkii, to keep the creation of a Toa of Light from happening. The search for the mask led it to Ta-Koro, where it began to terrorize until Toa Gali and Tahu began to fight them. During the battle, Lerahk managed to poison Tahu. This filled him with negative emotion and it began to kill him from the inside.

Lerahk and the other two later followed Jaller and Takua to Ko-Wahi. However, the Matoran were able to get away with the help of Kopaka, who froze them in a lake. They later escaped and eventually arrived at Kini-Nui, where they and three others, Vorahk, Kurahk, and Turahk, fought the six Toa Nuva. However, Lerahk, Guurahk, and Panrahk were frozen in a chunk of glass by the Toa Nuva, and later taken apart to build the Ussanui.

Abilities and Traits
Although not a cunning planner, Lerahk more than made up for what it lacked in intelligence with sheer power. The tip of their staffs could poison anything - plants, animals, soil, or any foe he might choose. Unlike Kurahk and Turahk, its power didn't work over a distance - the staff had to be in physical contact with the target.

Lerahk Kraata were lemon metallic (metallic green) and bright yellowish green (lime).

Lerahk was chosen by Makuta Teridax to go after the Avohkii because its power was the enemy of purity: The prospect of Ga-Matoran.

Set Information
''Lerahk's power is toxic! Whatever his Staff of Power touches becomes poisoned. Even the ground turns sickly green and plants wither away before the might of this Rahkshi. Lerahk is a patient seeker, willing to wait for hours for the perfect moment to act.''
