Iruini was a Toa Hagah of Air mutated by Roodaka into a Rahaga. As a Toa, Iruini carried a cyclone spear and a mechanical Rhotuka launcher whose spinner had the ability to heal. He wore the Kanohi Kualsi, the Great Mask of Quick Travel.[3, 4] As a Rahaga, he specialized in capturing Rahi climbers such as Brakas and cable crawlers. He carried a Rhotuka spinner with the snag power, which attached to its target and tangled up its limbs like a net. He also carried a staff whose movements could hypnotize Rahi.
Iruini relied on his patience and gentle manner to lure Rahi into his traps. His skill was so great that he could track a Rahi climber by the movements in the air. The snag spinners he launched tangled the creatures' limbs in a net and brought them down.
As a Rahaga, Iruini specialized in capturing climbing Rahi such as cable crawlers.
Iruini insisted that Keetongu was nothing but a myth.
When Iruini was transformed back into a Toa, he was thrilled to be a Toa again and eager to use his powers. Iruini hated living in the Archives as a Rahaga.
Iruini's Hagah mask was shaped to honor a fellow Kualsi wearer. It was the same shape as a standard Kualsi.
Iruini's mask was shaped to honor a past Toa. This Toa was not Nidhiki, as he was a traitor and was not to be honored.
Iruini's mask was not in the shape of the Mask of Stealth as it'd make no sense for him to wear a mask in tribute to a Toa who betrayed his friends.
A Toa's ability to complete their destiny without their team depended on what their destiny was. Part of Norik and Iruini's destinies was to save the other Rahaga, so their destinies were different from their team's.
- The notion that the Hagah sets were originally Toa Dume and Toa Nidhiki before being changed was inaccurate.
- The Toa Norik and Toa Iruini sets were not designed with characters in mind because that was not something set designers thought about. Someone on the story team suggested they could be Dume and Nidhiki, but Bob Thompson said no because he might have wanted to tell a Toa Nidhiki or Toa Dume story in the future and didn't want sets of them yet. The notion that the sets could represent Dume and Nidhiki only lasted about three seconds before it was rejected.
- The Toa Norik and Toa Iruini sets were going to be Toa Dume and Toa Nidhiki for about 15 seconds before that idea was rejected.
