Assimilator

Assimilators are the Scrin equivalent of the Nod Saboteur and GDI Engineer, used for repairing and capturing buildings, as well as capturing walker husks.

Background
These alarming creatures are capable of quickly integrating themselves into mechanical devices and control systems. Because of this, they are easily able to take control of enemy production facilities and use them for their own purposes. Assimilators may also quickly repair any damage sustained to Scrin structures, and perhaps most frighteningly of all, they are utterly invisible to the naked eye except when in motion.

a - as Kane's Wrath used a long-obsolete version of Tiberium Wars as its coding base, these changes were effectively reversed in the expansion pack and were never officially fixed.
