This is not actually a reference to a person, but to a yuga (an era).
In the present days we may be said to live in Kali Yuga, which is said to have started in 3102 BCE with the end of the Mahabharata war. From the Mahabharata text:
Parikshit was a great ruler and looked very well after Hastinapur. But
unknown to the Pandavas and Parikshit, a greater threat loomed with
the death of Lord Krishna.
During the ninth day of the Mahabharatha war between the Pandavas and
the Kauravas, the third yuga had ended and last yuga - Kali yuga had
started. However because of the power of Lord Krishna, Kali could not
spread all through the earth....
The Kali (destructive) Yuga is the last era in the Hinduist cycle of time. It follows the Satya (golden, perfect), Treta (some negative), and Dwapara (50% negative) Yugas. It is named after Kali, the Hindu female deity of death and destruction.
