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 Hagah.

Toa Hagah
Bomonga was a member of the Toa Hagah, six elite Toa who served the Brotherhood of Makuta. He was a Toa of Earth, although nothing else is known during that time. Later, the Toa Hagah discovered that the Brotherhood was actually enslaving and oppressing Matoran. The Toa Hagah then raided the Brotherhood of Makuta fortress and stole the Mask of Light. In the process, all except for Norik and Iruini were captured. Bomonga and the other three Toa were then mutated by Roodaka into the Rahaga. They were eventually rescued by Norik and Iruini, but then they were also mutated.

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 between being mutated to when he and the other Rahaga saved the Toa Hordika from falling to their deaths is mostly unknown. He and Whenua later searched for parts to make an Airship, 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.

Transformation
After they were transformed back into Toa Hagah by Roodaka, Bomonga and the others kept watch over Roodaka, and despite their mutual hatred, protected her home island from being destroyed. It is unknown what he and the other Rahaga did after Roodaka was drafted to hunt down Miserix by the Order of Mata Nui.

Parallel Universe
Takanuva intercepted the company, during which he lied to the two Toa, convincing them to allow him to join. However, it was revealed that Bomonga killed Brutaka, who Takanuva was looking for, when the Toa of Light was attempting to create another lie as to who is stealing the Vahi.

Abilities and Traits
As a Toa of Earth Bomonga can create, control, and absorb earth. He had a seismic spear as a Toa Hagah, according to Dark Mirror This also gives him the ability to control earth, and create earthquakes. These abilities were lost when he was turned into a Rahaga, but he has since regained his powers.

Tools
As a Rahaga, Bomonga could detect Rahi through vibrations in the earth using his staff. His Rhotuka could fly silently through the air, and strike his prey and hold it motionless.
