When the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, "Come and see!" 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.
— Revelation 6:7-8˄ NIV

Death the rider of the pale green horse.
Carries a scythe and rides upon a sickened horse that is pale green.
When he rides a trail of the dead and hell follows his footsteps. He controls the realm of the dead by using swords, beasts, and diseases
