This is video of what could be the sprit of the 4th Seal Rider from Revelation 6: 7-8
Rev. 6:7 When he opened the fourth seal, I heard the voice of the fourth living creature call out, Come!
Rev. 6:8 I looked and there was a pale green(sickly) horse! Its rider's name was Death, and Hades(Hell) followed with him; they were given authority over a fourth of the earth, to kill with sword, famine, and pestilence, and by the wild animals of the earth.
