Kongu

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

Matoran
On Metru Nui, Kongu was one of the Matoran who ran the chutes, and the Dark Hunter Nidhiki forced him to reverse the flow of one chute to send three escaping Toa Metru right to him.

Starting out on Mata Nui as a bird wrangler, Kongu eventually became captain of the Gukko Force of Le-Koro and Turaga Matau's right hand, where he rode a Gukko bird named Ka. This makes him an exceptionally good pilot, navigator and mapmaker. At one point, several of the Le-Matoran, including Turaga Matau, were captured by a Nui-Rama swarm and taken to their nest, and Kongu, Tamaru, Takua, and a few others went to help. Also, when the entire village of Le-Koro, including Matau and Toa Lewa, were corrupted by Krana, Kongu and Tamaru escaped and teamed with several others to help free Le-Koro. He and Tamaru were on the Le-Koro kolhii team.

After returning to Metru Nui, he join with Jaller team to rescue the Toa Nuva in Voya Nui. In the way, he found a abandoned Suletu. Later he as forced to use it in Karzanhi realm. He and others escaped in Toa Canisters and arrived in Voya Nui, became the Toa Inika.

Became a Toa
Toa Kongu just can't believe it: here he is, a powerful Toa-hero and a veteran Gukko bird rider, and Nuparu gets the Mask of Flight! Worse, thanks to his new mask, he now knows what everyone around him is thinking all the time, especially about him. It leads to a lot of griping on his part, but when battle starts, he is always in the thick of it. He has begun training Nuparu in flying techniques to make sure, he says, that Nuparu doesn't go and break the Mask of Flight.

Kongu is a Toa of Air and uses a Energy Crossbow. His mask is a Suletu Mask of Telepathy, which lets him read thoughts, sense strong emotions, and project his own thoughts to others. Unfortunately, though, he has not yet learned how to switch his mask off. The Suletu appears to be broken around the left eye and replaced with a scaly reptilian growth, but that may just be how a Suletu is supposed to look. As a Matoran, Kongu was the Captain of Le-Koro's Gukko Force.
