I was not referring to a person in Daniel, but to a vision, where each kingdom was portrayed as a beast. This endtime Babylon has character traits of each of those beasts (as well as carries on the religion of each).

Yes, the Antichrist is a person who rules a one-world empire. The seven heads are the seven empires that went before, according to Revelation seventeen: Egypt, Assyria, Babylon, Medo-Persia, Greece, Rome, Endtimes Rome, and the Antichrist's final empire (seven year rule).

Revelation 17:9-11 And here is the mind which hath wisdom. The seven heads are seven mountains, on which the woman sitteth. And there are seven kings: five are fallen, and one is, and the other is not yet come; and when he cometh, he must continue a short space. And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition.
