The following Scripture is the main witness of the second beast given in Rev. being a specific entity or person...
Rev 13:11-18
11 And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon.
That is the Antichrist trying to deceive with appearing like a lamb. He will appear on earth "like a lamb", but he speaks "as a dragon". That "dragon" title per God's Word in Rev.12:9 and 20:2 is another title for Satan himself. Doesn't matter who others claim that "dragon" is, for God's Word is supreme authority on that "dragon" title applied to Satan.
12 And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed.
This second beast, a person that will appear like a lamb, but speak as a dragon, will use all the power of the FIRST BEAST. What was the first beast given in Rev.13? The first beast is the ten horned, ten crowned, seven headed beast KINGDOM over all nations and peoples of the world (Rev.13:1-2 with its definition by Christ in Rev.17:15, and by Christ's comparison to the beast kingdoms in Daniel 7).
13 And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men,
14 And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.
This second beast is coming to work great wonders and miracles on the earth in the sight of men, all to deceive the whole world with. Notice that working is not with a literal sword in war. This event is pointing to a time of world peace on the earth, after all wars have stopped.
15 And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed.
Just as what king Nebuchadnezzar did with a golden image of himself, this second beast will institute an "image of the beast" for bowing in false worship. The whole world will be required to bow in worship to that image of the beast idol abomination. That is about the "abomination of desolation" even Christ warned of from the Book of Daniel. A parallel to it is also given in Ezekiel 8 with false worship inside a temple in Jerusalem. For those who refuse to bow to that image of the beast idol, they are to be killed.
16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
A mark for buying and selling is to be also instituted, which will be for the deceived who fall to bowing to worship that image of the beast.
18 Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.
(KJV)
We are to understand that second beast ("another beast") is about a certain "man". That man is about the 'man of sin' Paul warned of in 2 Thess.2 that is to come to sit in the temple of God, showing himself that he is God. That is the same sin Satan did in first rebelling against God in the time of old.
