They check in, but they don't check out

Nasty little roach
As loathsome as its namesake
And as hard to kill

My first thought when I saw this unit was called the "roach" was, that's a weird name for a Zerg unit! Most Zerg names are original names that have that alien feel. I mean we have Queen and Drone and Overlord, but at least those are reminiscent of the hive mentality. "Roach" sounds immersion-breaking.

But "Roach" is still an insectoid name, and it certainly does fit this Zerg unit! Roaches are scary, next to impossible to kill, and I don't know about you but I always hate seeing them. Unlike in the game, though, I do not recommend dealing with cockroaches with machine guns or flamethrowers.
