The grotesques are made from various Rat Ogre parts. Including 2 from the Island of Blood box set, and the one from the Screaming Bell kit. The latter 3 rat ogres come with smaller heads compared to the regular Rat Ogre kits. I went ahead and gave them all the same size bigger heads to keep them uniform.
Each one has on their backs a set of coils which I will be painting in a glow. This is to represent that these guys teleport in to the battlefield, lead by their own Haemonculus with Webway Portal, who will also have a similar coil on his back. And what are these creations without some exposed wire? Data cable wire is used on a lot of my projects. With 9 Grotesques dropping in without scatter, it should be of major concern to any enemy of the Verminlord.
