Kidhiki

Kidhiki was a Dark Hunter, who helped Alex during Alliance of the Enemies. He was Nekka's brother. He had elemental powers and used them as a Nova Blast to send Aino and Iruini flying, seemingly blown up. But in fact, they rocketed into the air and landed to Kowa Mountains. He was later killed by Toa Aino, since he had been weakened by the Nova Blast.
