He is orange and has the face of a cat. When the general was freed, his body resembled a Squid Khan's.
In Fright Fight Night, his mask was discovered embedded in the side of a towering rock formation by Jackie Chan. The Enforcers attempted to ambush Jackie on his way to Section 13, but failed. Later, Paco put on the mask (unbeknownst of its magical properties) so that he could win a costume competition for Halloween. He eventually removed it himself at the end of the episode with the use of a Japanese octopus' tentacle.
In Ninja Twilight, after the nine masks was joined together, all of the Oni generals were freed and tried to destroy the world. Orenji was walking with Murasaki to one of the four corners of the earth. They were briefly defeated by Uncle and Tohru but Tarakudo managed to capture them. After Jade put Tarakudo's Mask on his face, all the Oni and Shadowkhan were imprisoned within.
