The False Prophet (the second beast) is the religious power.
This is another beast coming up in Revelation 13:11 if memory serves.
The first Beast (”Antichrist”, colloquially) that is mentioned is a world leader, portrayed as a “messiah”.
The False Prophet demands and enforces worship of the Antichrist by making an image come to life - just as Satan’s false prophets turned their staffs into snakes, I expect he will bring a statue to “life” by the same Satanic power. This will astonish the world; plus the miraculous recovery of the Antichrist who appeared to have been killed.
It is the False Prophet that actually enforces the Mark of the Beast upon the world (except for Tribulation Saints who refuse to their deaths)
YMMV
