Miklos Karlovassi was a 20th century geophysicist who, along with his wife Irina, was the biological parent of the Augment Udar, whose embryo was put into cold storage after the Eugenics Wars.
In 2154, after rescuing Udar, whose embryo had been stolen and brought to term by Arik Soong in 2134, from exile on a planet in the Trialas system, Starfleet captain Jonathan Archer showed him a PADD with biological information on his parents, which they had retrieved from Soong's computer.

In the final draft script of "Cold Station 12", Miklos Karlovossi was described as being "in his '40's" at the time his photo was taken. Regarding the image itself, the script specified, "It looks like it could have been taken for a university yearbook."
