Zergrinch Warg

Wargs are powerful versions of the Hydralisk that were employed by the Zerginch. As their master was killed on Planet Christmas, it is likely that the Wargs were erradicated along with him.

Trivia
In truth, the Warg is simply a renamed Hunter Killer, given that its stats are identical. The only difference is that while the Hunter Killer is shaded red, the Warg is teal.

The Wargs may have been named after the Wargs of The Lord of the Rings; viscious, intelligent wolves ridden by orcs.
