Fangs are the elongated, sharpened teeth displayed mostly by eight-balls, although higher angels presumably possess fangs as well that they can retract at will due to their lifelong experience with possessing their own corporeal bodies.

The fangs of eight-balls are believed by the scientists of Vega to be due to an evaporation of enamel in the teeth due to possession,[1] although this is not the case as many eight-balls, such as Clementine Riesen, have shown healthy teeth along with fangs, thus the poor condition of eight-ball fangs may simply be due to poor hygiene and cannibalistic eating habits.
