well again don't forget this is mere speculation on our part.. For all we know the rest of the beast might not follow the same pattern.. but just to clarify I think the key is that beast fed off humanity evil AND are bundle of said evil,

Goetia is a beast that feed of pity that are born due to pride of man, but he himself is a mass bundle of pride. While we don't know much bout Tiamat and fou but for Kiara is undoubtly the embodiement of lust personified.

Thus we can assume that Fou is a mass of envy and Tiamat is either mass of something too if this theory hold it's ground and naturally the true beast III will be a mass of lust given form THAT are not human in origin unlike Kiara which is essentially a man-made beast.
