Homura Witch Familiar Analasis (Puella Magi Madoka Magica)

Looking at Homura's familiars may look weird. The two are Alive Teeth and Nut 
Crackers. But why? Well I'll tell you why! Teeth can represent power. Teeth destroy food and meat when we eat. Essentially becoming powerful through destruction. Who got their power from destroying things? Homura. She became the devil (really powerful figure) by destroying the world or whatever happened. She destroys things and in return gets power.
