According to mankind’s understanding of evolutionary theory, the Black Dragons should be born on a planet that has gravitational force 20 times larger than Earth's, a barren landscape, a lack of food, low concentration of atmospheric oxygen, and was prone to frequent natural disaster.
It was the logical explanation behind why the Black Dragon was such a powerful super species. Survival of the fittest, natural selection, one of the most accepted theories within biology.
