Keetongu

Keetongu were a race of powerful intelligent biped Rahi from the same island as the Tahtorak. Only one of this species has been seen, and might be the last of his kind after his island was conquered by the Visorak.

The Last Keetongu
This last Keetongu lived in a Ko-Metru cave that could be accessed by an underground chute in Metru Nui. The Toa Hordika and the Rahaga found him and got him to help defeat the Visorak and reverse their mutations. In the Toa's siege of the Coliseum, Roodaka baited Keetongu into killing the Visorak's king, Sidorak. When Makuta later came to the city, Keetongu sensed his evil and attacked, only to be beaten into unconsciousness. He had left Metru Nui by the time the Matoran returned a thousand years later, and has not been seen since.He is beleived to be going through the Universe,aiding other victems of the Visorak,like the Toa Hordika.

Powers, Abilities, and Traits
The known Keetongu could heal anyone afflicted by poison or venom, as long as the poison had not fully taken effect, and his spinning shield array could absorb attacks that he could then send back at his opponent using his Rhotuka spinner (though he could not absorb the spinners of Roodaka or Sidorak). His single visible eye could not actually see, but it could detect the good or evil in someone. The eyes that he used to see with were hidden behind his false eye. He also carried a climbing claw that can be used as a melee weapon. Since the one known Keetongu was the only one left in existence, it is impossible to tell which powers are shared by the entire race.
