Fenrakk was a monstrous mutant spider Rahi which served as a guardian of the Ignika during the Toa Inika's mission to retrieve the mask. It was mutated by the Ignika from a normal Fenrakk spawn to a larger size and fused to Vezon to serve as an additional guardian. It already possessed great strength and acidic saliva, then once fused shared Vezon's ability to absorb kinetic energy.
Kardas was a dragon Rahi which battled the Toa Inika in the Chamber of Life. Under the terms of the Ignika's curse upon Vezon and Fenrakk, any defeat would result in Fenrakk mutating into a fiercer shape. Fenrakk turned into Kardas after the Toa Inika defeated Vezon and Fenrakk. Kardas was a massive winged beast capable of discharging blasts of raw energy from its mouth.
Vezon's monstrous creature, Fenrakk, pitted his incredible strength against the Toa Inika. When Vezon and Fenrakk were defeated, they rose again as Vezon and the Kardas dragon.

The Fenrakk spider was the partner/pet of Vezon. Like its master, it too could absorb the kinetic energy of blows directed against it and grow stronger. Fenrakk could not truly be beaten as long as Vezon wore the mask; if defeated it would simply transform into another kind of creature. Fenrakk possessed enormous strength and acidic saliva. It was defeated by the Toa Inika and transformed into the Kardas Dragon.
