Iruini

Iruini was a Toa Hagah of Air before he become a Rahaga.

Toa Hagah
Iruini was a Toa of Air who wore golden armor. 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.

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

Iruini's mask was the Kualsi, which allowed him to teleport to any place within his line of sight. His Cyclone Spear allowed 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 tangleing power, as well as a Rahaga Staff
