Rat Ogre

If mutation was an art, then Rat Ogres would be the masterpiece of the Skaven Clan Moulder's endless experiments with Warpstone. Created with bits of organic material from dozens of creatures, only the strongest survive the terrible birth conditions that they are created in. Rat Ogres are hulking monstrosities, let loose on the battlefield by their Packmasters, whom are much like those who drive forth Clan Moulder's Giant Rats. Once unleashed, Rat Ogres are a terrible sight to behold, and are great killing machines that were born to fight and tear up infantry like dolls.

Tome Text
''Rat Ogres are the byproduct of years of surgical experimentation, selective breeding, and Warpstone enhancement to Clan Rat stock by the so-called Master Mutators of Clan Moulder. The massively-muscled beasts are led into battle by cruel packmasters like beasts of burden, seemingly incapable of rational or independent thought. They live only to serve.''
