Iruini

Iruini was a Toa Hagah of Air before he become a Rahaga. Later he was turned back into the Toa Hagah of Air.

Toa
Not much is known of Iruini's life before his recruitment into the Toa Hagah. What is known was that he was active as a Toa for quite some time beforehand, operating as a member of another Toa team. Whether or not Iruini was the leader of this team hasn't been revealed. When the Brotherhood of Makuta decided that Makuta Teridax needed Toa bodyguards, Iruini was selected as representative Toa of Air of the new team. He was endowed with metallic armor to indicate his status as an elite Toa and his former teammates presented him with his current Kanohi Kualsi as a badge of honor.

Toa Hagah
Iruini was a Toa of Air who wore golden armor. Iruini's new Toa team performed this task well and protected Teridax from things like Rahi intrusions. He quit the team after they rebelled against the Brotherhood of Makuta, believing they spent too much time on huge menaces and not enough on ever-present dangers. So he escaped the ambush that took most of his team and allied with Norik on a quest to save Gaaki, Pouks, Kualus and Bomonga from the Brotherhood's Visorak. He and Norik managed to rescue them, but were mutated into Rahaga.

Rahaga
Iruini was a master of camouflage who searched for climbing Rahi among the tangled cables and chutes of Le-Metru. He used his staff to hypnotize Rahi and his snag spinner to tangle their limbs. Iruini believed that there was much to learn from Rahi, including how to relax and play rather than being so serious all the time. He helped the Toa Hordika on a mission to stop Roodaka and Sidorak. They succeeded, and he, along with the other Rahaga, tried to stop Visorak from mutating other Rahi on various islands. They were recently transformed by Roodaka into their normal selves, under the Toa Nuva's command.

Powers, Mask, and Tools
As a Toa of Air Iruini can create, control, and absorb air, as well as other things.

Iruini's mask is the Kualsi, which allows him to teleport to any place within his line of sight. His Cyclone Spear allows him to focus his air powers, and his Rhotuka Shield created Rhotuka Spinners with a healing power.

As a Rahaga, Iruini used a Rhotuka Spinner with a tangling power, as well as a Rahaga Staff.
