You've seen the Demonic Warriors - now here are the Mutant Servants in 15mm scale from Mighty Armies' Sorcerer's Legion.
PhilGreg Painters painted these 40 figures for TMP (combined from two boxed sets). Basing was done here at TMP.
There are four poses: raised left arm, swinging left arm, arms down, and raised right arm. All look appropriately brutish and shambling.
PhilGreg Painters varied the look by changing the clothing colors, and by painting hair on some of them.
