As Yuji Kiba, Yuka Osada and Naoya Kaido attempted to infiltrate the Smart Brain headquarters to obtain the Emperor's Belts, the three were led into a trap and wound up in the room housing the Elasmotherium Orphnoch. The Elasmotherium Orphnoch killed Yuka by slamming her into a wall before devouring Kaido, leaving Kiba mentally broken from losing his friends.
The Elasmotherium Orphnoch was later transported to the Smart Brain Super Arena so it could devour Mari on live television. However, the event was interrupted by Faiz, who showed up to rescue Mari. Faiz attempted to fight off the Orphnoch with the help of Auto Vajin but failed and was knocked into the bleachers as the Elasmotherium Orphnoch crushed Auto Vajin. As the Elasmotherium Orphnoch was now rampaging, Smart Brain raised the metal bars to trap it once more and locked Mari in a cage to prevent her from escaping. They then placed the cage near the Elasmother Orphnoch so it could consume Mari.
However, with help from Yuji Kiba as Kamen Rider Orga, Faiz saves Mari and destroys the Elasmotherium Orphnoch with his Blaster Form's Photon Blaster.
