Here are my interpretation of 2 rahis: The Parirau and the Water Wraith
Parirau
This is an original rahi. It is an extremly powerful and intelligent bird-like rahi that uses his 4 sharped wings to fly at high speed and slice his oponents. His talons are also a deady weapon, but his greatest strength lies in the ability to send disintergrating energy blast to its oponent with its beek. Calm by nature, it rarely attacks, but provoking his anger can lead to cataclysm. Some lived on the northern continent and on the southern islands in isolated areas.
Before becoming a toa Hagah, Kualus mets a colony of these rahis during one of his travels, and after studying them, it appears that these rahis are related to the Gukko in the same way that Manas are related to Ussal according to Whenua.
This rahi exist in different variant depending on the environement. Six have been established and are related to a specific element (Fire, Water, earth, stone, air and ice)
