The Antichrist is part of an "unholy trinity" consisting of Satan, otherwise known as the devil or the dragon; and his two sons: the first beast, the Antichrist, having 10 horns, and 7 heads; and the second beast, the False Prophet, with 2 horns. This corresponds, in reverse, to the Holy Trinity of Father, Son, and Holy Ghost. It is explained elsewhere in Revelation that the 10 horns of the Antichrist are the 10 nations of the confederation of ten states that he rules:
Revelation 17:12: "And the ten horns which thou sawest are ten kings which have received no kingdom as yet; but receive power as kings one hour with the beast".
This sounds like Russia and the Commonwealth of Independent States, which does consist of slightly more than 10 states. Also, in Revelation 17:3 the 10-horned beast is scarlet-colored: Russia, of course, is associated with the color red. Interestingly, Russia is a Scorpio-- born November 7, 1917, and Jupiter (corresponding to the Antichrist) was in Scorpio on August 31, I think the first beast and second beast may be referring to both individuals, and countries. Biblical symbols frequently have double and triple meanings-- at one level, the 2 beasts may be countries; at another level, they may be individuals. An unholy trinity of dragon/ first beast may be a Red China / Russia military alliance, with Russia's President Putin the first beast. This would also make sense of the description of the Antichrist as: mouth of a lion (Hong Kong in China?), feet of a bear (Russia), and gets his power from the dragon (Red China).
