Aka is one of Tarakudo's Oni Generals who could summon the Mantis Khan. Nobody wore his mask.


He is red, has yellow eyes and hairy eyebrows. Unlike the Mantis Khan, he has two legs instead of four.



Hundreds of years ago, the spirits of the nine Oni Generals were sealed within masks, where they were helpless and could not use their powers.

Season 4

In Ninja Twilight, his mask was found embedded onto the figurehead of a sunken ship on the ocean floor. Jade noted acquiring this mask was too easy, as it turned out Tarakudo had other plans. After the nine masks was joined together, all of the Oni generals were freed and tried to destroy the world. Aka was walking with Rairakku to one of the four corners of the earth. They were briefly defeated by Jackie and Super Moose but Tarakudo managed to capture them. After Jade put Tarakudo's Mask on his face, all the Oni and Shadowkhan were imprisoned within.
