Nikkorax, Converted Innkeeper, is a Unique Summoner of the Dead found in The Haunted Inn in Act V of Diablo III. He spawns for the Haunted Inn event.
In combat, he has the Teleporter affix. Instead of Shadows, he summons Vicious Hounds, Revenant Archers and Revenant Soldiers, and is also able to create Frost explosions anywhere across the inn (these do not Freeze target, but deal high instant Cold damage).
