This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Blafard (America)
A blafard is an imaginary creature purportedly found in the early United States. Blafards, also called "kackerlackes", were "strange albinos long surmised to be the result of some kind of simian crossbreeding", but of an "accidental variety". Blafards were imagined by Europeans, notably Cornelius De Pauw in the 18th century.
This creature was a symbol of the degeneration of America in the minds of Europeans, along with the "hermaphrodite", which "epitomized Americans' sexual disorder. Blafards were imagined to be "caused by a deficiency 'in their parents' spermatic liquor'" and were "absolutely deprived of the power of generation, or did not engender children that resemble them".
