Kongu

Kongu, as once a single love-flying Le-Matoran, now became a Toa Inika of Air.

Matoran
On Metru Nui, Kongu worked as a chute monitor. He wore a Bright Bluish Green Ruru, replaced by a Bright Bluish Green Miru later for undisclosed reasons (most likely because his mask broke when being transported to Mata-Nui). During Bionicle 2: Legends of Metru Nui, Nidhiki and Krekka threatened him to change the direction of a chute where three of the Toa Metru were in, he had no choice but reverted it. Later, he was put in a Matoran Pod and was eventually awakened by the now Turaga of Mata Nui.

During the time of the Rahi attacks from Makuta, Kongu became an expert bird wrangler and was appointed captain of the Gukko Force. He led Takua as a second on a Gukko bird into a hive of Nui-Rama to save several Le-Matoran and one Onu-Matoran, Taipu, who had been taken by the Nui-Rama under command of Toa Lewa, who had been taken by Makuta. Kongu flew into the hive while Takua was frantically shooting bamboo Kanoka disks at the Nui-Rama onslaught. But once in, they were trapped with the others. Only by Onua coming in and saving Lewa were they saved. Later, Kongu led the Gukko Force to the aid of the Chronicler's Company at the Kini-Nui.

Toa Inika
After the return to Metru Nui, Kongu left to help find the Toa Nuva. Along with Jaller, Hahli, Matoro, Hewkii, and Nuparu, they traveled south to a land bridge to Karzahni. They were captured and Karzahni made them wear new masks. Kongu rejected his offered mask, deciding to wear a Suletu that they had found earlier. Later, they found a Matoran who made six canisters, and they escaped.

Like all other Toa Inika; Toa Kongu Inika has lightning powers with his Air powers, and must always be used together (i.e. - He cannot create a windstorm without it being coated with lightning, or he can't make a tornado without lightning inside it).
