Visuals: On a black background, there is a golden Sudarshana Chakra spinning around with various orange shockwaves passing by. After 13 seconds, it crossfades to the same scene, but with the curved golden text "CHAKRAPRODUCTION" in front of the Chakra along with 5 planet-like spheres rotating around the gear and the text.

Trivia: The Sudarshana Chakra is a divine discus abbreviated to the Hindu god Vishnu, and is generally portrayed on the right rear hand of Vishnu's four hands.

Variant: An early variant was spotted on Bolidan where in front of the Chakra, there is a set of red Bengali text zooming in which translates to:

PRESENTS

Technique: CGI.

Audio: A bunch of loud whooshes and explosions during the first part, and a (possibly) stock synth theme at the end.

Audio variant: The early variant used the film's opening theme with a few stock whoosh sound effects.

Availability:

The original variant was seen on Bolidan.
The later variant on the other hand can be seen on Jangi, Kablar Biye, Sunyo Theke Suru and Ram Rahim.
