This character is a member of Spock's family native to the Mirror universe.
For the primary universe counterpart, see Skon.

In the mirror universe, Skon was a male Vulcan who lived in the 21st and 22nd centuries. Skon was the son of Solkar, the captain of the Vulcan survey ship T'Plana-Hath. Skon, in turn, was the father of Sarek and the grandfather of Spock.

The mirror counterpart of Skon has never been seen or referred to onscreen, but his existence is implied because mirror counterparts of Sarek and Spock also exist. Skon must have been born before first contact between Earth and Vulcan, as his father Solkar is shot and killed by Zefram Cochrane during that contact.
