4 Horsemen 5

One was followed by Hades, One had authority over a fourth of the Earth, Can cause famines, Can cause infections, Can seemingly incite "wild beasts" to kill and Can kill with a sword

8 I looked, and there before me was a pale horse! Its rider was named Death, and Hades was following close behind him. They were given power over a fourth of the earth to kill by sword, famine and plague, and by the wild beasts of the earth.
