Atka is a very strong warrior Nita was supposed to marry. However, the Great Spirits interrupted the wedding ceremony, not wanting Nita to marry Atka.
Nita then went on a journey to Honkani Falls to burn an amulet that was given to her by Kenai so she can marry Atka. After her task was done, she returns to her village, but was hesitant in carrying out the wedding ceremony. Atka was one of the warriors who chased after Kenai and Koda and was intent on hunting him down. In the film's climax, Atka nearly kills Kenai by pushing him fall off a cliff into shallow water below, and Nita yells at Atka for hurting Kenai as she runs to the bear's side, leaving Atka confused and remorseful over his actions. Atka was not seen for the remainder of the movie. (after he watches Nita turn into a bear by the Great Spirits of Sitka and Koda's Mother. And Atka gets arrested and punished by the villagers because he is guilty for almost killing Kenai, and Atka became a prisoner.)
Role in the series
atka becomes a member of the fang empire after his imprisonment, and is desginated as an imperial hunter. however, it depends if Yru17 will allow it, as he already requested the villain leage absint from the first movie. (dispite an unexsected appearence of Shen (Who reformed afterwords, and wanted to reformed, so he tecnecly does not count) and Shadow Fagin, but Scroopfan can assure you that Scroopfan still kept his word of not letting The real fagin make an appearence or the appearence of the other leagers.)
