Creature:B

The B is a strange organism. It is unknown if their design is a simple coincidence or if a race who had kept an eye on mankind before altering a number of species in an attempt to communicate with man that they had watched over them. While the Human race was in fact the race who first discovered them, no "galactic god" species has ever shown themselves to state they created the species. They are therefore left as a mystery of the galaxy, and a minor wonder.
