Mass Effect Krogan Sure they are ugly, but awesome looking! Before the genophage, they could reproduce very quickly and were bred for war. They have powerful regeneration abilities. They are highly resistant to bio-hazardous conditions. They are fun to talk to. They find enjoyment in blasting monkeys with high powered weaponry. They head-butt like a BAWS! They are stubbornly loyal. Give them a shotgun, and they will hold a position forever.
