For the grand finale stunt, Krishna competed against Karan Veer Mehra and Gashmeer Mahajani, two of the strongest contenders from the very beginning of the show. The final stunt was as thrilling as the climax of a blockbuster movie. Contestants were positioned on top of a bridge and had to zipline through the course, then jump into the water. Once in the water, they had to unlock themselves and swim to a platform built in the middle of water, where they would retrieve a water scooter. With the help of that water scooter, contestants had to return to land, locate a box with a buzzer, and press it to signal the arrival of a chopper. Contestants had to climb up the net attached to the chopper, which was filled with explosives. They had to reach out for a long ladder to climb and eventually enter the chopper. Once inside, they had to press a second buzzer, and the net filled with explosives would release and explode in the water. This marked the completion of the stunt.
Krishna's performance in this intense stunt earned her the runner-up spot, as she lost to Karan Veer Mehra but managed to beat this season's favorite to win, Gashmeer Mahajani. Despite not winning, Krishna expressed her gratitude for the experience, saying she 'would do it all over again' if given the chance, showcasing true sportsmanship. Currently, Krishna is focused on expanding her MMA Matrix Gym franchise with branches in cities such as Pune, Pathankot, Lucknow, Solapur, and Kolkata.
