Kagami no Oni

Kagami no Oni are roughly human-sezed and humanoid in appearance, and were created by The Maw to counter the ranks of the Lost during the civil war in the Shadowlands in the Twelfth century. Kagami no Oni are deceptively powerful, in relation to their size, and have an incredibly dense muscular and skeletal structure. This results in their weight being roughly three times that of a human being their size. Their physical and athletic strengths are similar to that of large apes, but they are also very intelligent. They relish taunting their opponents, and can easily adapt to new weapons and tactics. (CoR3E pp. 121-122)
