The popular theory that I hear is that Blackbeard ate a mythical Zoan class Cerberus fruit. This allows him to transform into a dog with three heads, and therefore, three separate stomachs, one for each fruit. The basis for this idea came from the fact that Blackbeard's Jolly Roger has three skulls.
