Nekka

Nekka was a powerful Dark Hunter who went to work to Alex with Kidhiki. They were assigned to stop Henkka, Tapio, Aino, Iruini, Pewka, and later Matoran Hordika from coming to his fortress. But even though the Dark Hunters were powerful, they didn't succeed. While Kidhiki was killed by Aino earlier, Nekka even got fused to Ketawnki. After the defusion, Nekka was more powerful and escaped with Inwirn, Juho and Dumpa. Nekka worked for Inwirn then, but got later killed by Aino too.
