Gretchin

The Wee Green Men
Right ya git, you'z a Gretchin now, everything hates you, you have the strength, stamina and survivability of a small child and even your boss might use you as extra ammo. The good thing is there's a lot of you, as in, possibly trillions.

But are you useful?
Indeed you are useful, you the only one who can build actually, so make those pile of guns so your boss and other orks can get shit tons of stikkbombs and bomb the fuck out of everyone I mean, get some good choppas and sluggas to WAAAAAAAAAAGH on humies and get some more dakka to become better...except you, get those walls and turrets up, ya squig-bait piece of rot-gut.
