The final boss has an intro in which it drops stuff on the 4 switches to block it from being activated. As in the mist room, you are free to move during this animation and can start to use the switches.
Using anuman to switch form will recenter the camera on the character allowing to see where you need to move during the boss intro.
If you are in hack range of the bomb before he catches you in the end, you are able to hack it during the final animation where indra comes back to save you.
Start up left and hack the switch with the drone, you need to be able to land as far right as possible so you can reach the other switches fast enough. Switch to Indra form to recenter the camera then hack the top right then bottom right switches. Finally drop down to the floor while running to the final switch, this way you may be able to avoid its attacks. Hit the blocking stuff 10 times to destroy it then start moving right and hack it from a distance, so you have enough time to run to the bomb. Stay in hack range of the bomb then hack it when the boss grabs you.
