Emerald Drashig
From Tardis Wiki, the free Doctor Who reference
Emerald Drashigs were the smallest and deadliest species of Drashig, more vicious than any predator in the known universe. Emerald Drashigs lived in the rainforests on DrashigWorld. They travelled in packs of five, with the alpha emerald having a white marking. A single Emerald wiped out a group of soldiers in the jungles of Hydroxus 3. (AUDIO: Planet of the Drashigs)
