Stalkers

Stalkers are a Scorn enemy type. They are Dregs reanimated with Dark Ether, allied with the Scorn and The Witness. They fight with Fallen maces up close and Scorn repeater pistols and grenades at range, and often sprint at enemies with raised clubs. They first appeared in Forsaken.

Lost Sectors

The Extraction Master Lost Sector in Quagmire on Savathûn's Throne World is full of Stalkers. The first room has Stalkers, Lurkers and an Overload Scorn Chieftain, and the second room has dozens of Stalkers and Acolytes alongside Hive Knights.
