Bomonga

Bomonga was the Toa Hagah of Earth before he was mutated by Roodaka and became a Rahaga. Just recently, he, along with the other Rahaga, have been transformed back into Toa heroes.

Toa
Not much is known about Bomonga's life as a Toa. What is known is that he was a bodyguard for Makuta, along with the other Toa Hagah, but rebelled when his team found out Makuta was enslaving Matoran. After winning, Roodaka ambushed him, Gaaki, Kualus, and Pouks, and mutated them into Rahaga. Later, Norik and Iruini returned to rescue them, and were mutated themselves.

Rahaga
Bomonga preferred to work alone, searching for Rahi that were nocturnal or remained hidden. His staff allowed him to detect the presence of Rahi, and his silence spinners could paralyze a Rahi with a touch. Bomonga searched for Rahi under cover of darkness and would sometimes burrow into the earth to wait for the creatures to come near.

Bomonga's history after being mutated is mostly unknown until he and the other Rahaga saved the Toa Hordika from falling to their deaths. He and Whenua later searched for parts to make a Vahki Transport, and were attacked by a Kahgarak and sent to the Zone of Darkness. They escaped when Sidorak called the Zivon to the battle that was taking place outside an airship hangar in Le-Metru, and joined the battle.
