Bermuda-Shen and Hor-gus-us

When science exploration begins to go into deep space they were warned not to bring any type of living species back to Earth that it could pose a threat to humanity very existence. Yet, some wretched scientists didn't obey this law. Instead they brought back a living plant that could sang. Not knowing the red and black dust upon it was residue from two entities that wiped themselves out of existence.
The black dust transformed on earth escaping to effect laboratory primates in a worse way. The red dust transformed going into the wind and changed the horses everywhere into a humanoid creature that would be mankind's greatest protection against a nightmare monstrous predator who wants to devour all humanity.
