Rat Ogre

"Not truly Skaven, the Rat Ogres, but they are aberrations nonetheless. Bred in the pits of the Master Moulders, no two Rat Ogres are the same. When
driven by Moulder’s Packmasters, Rat Ogres are effective weapons of war. If left to their own devices, however, they are just as likely to feed on nearby
offal as to kill the Skaven or their enemies.
—Steffan Paulus Adelhof, Scholar of Wolfenburg"
