  We explore different (and complementary) views of spinors and their exotic
counterparts, linking the very existence of the later to the presence of black
holes. Moreover, we investigate the effects of the exotic term in the Hawking
radiation emission rate, as well as its extremes, for asymptotically flat black
holes solutions of general relativity. We show that, under certain
circumstances, the emission rate extreme condition fixates an equation from
which the exotic term could be inferred.
