The "Antichrist" is not mentioned in Revelation so you got the wrong guy. The antichrist or many antichrists are mentioned in John's letters, not his book of Revelation.
Below are Revelation scriptures that refer to activities associated with the Antichrist.
Rev. 6:12 pertains to when the Antichrist breaks the peace treaty.
Rev. 6:12 And I looked when He broke the sixth seal, and there was a great earthquake; and the sun became black as sackcloth
made of hair, and the whole moon became like blood; 13 and the stars of the sky fell to the earth, as a fig tree casts its unripe figs when shaken by a great wind. 14 And the sky was split apart like a scroll when it is rolled up; and every mountain and island were moved out of their places. 15 And the kings of the earth and the great men and the commanders and the rich and the strong and every slave and free man, hid themselves in the caves and among the rocks of the mountains; 16 and they said to the mountains and to the rocks, “Fall on us and hide us from the presence of Him who sits on the throne, and from the wrath of the Lamb; 17 for the great day of their wrath has come; and who is able to stand?”
Rev. 11:1-13 marks the time the Antichrist breaks the peace treaty.
Rev. 11:1 And there was given me a measuring rod like a staff; and someone said, “Rise and measure the temple of God, and the altar, and those who worship in it. 2 “And leave out the court which is outside the temple, and do not measure it, for it has been given to the nations; and they will tread under foot the holy city for forty-two months. 3 “And I will grant
authority to my two witnesses, and they will prophesy for twelve hundred and sixty days, clothed in sackcloth.” 4 These are the two olive trees and the two lampstands that stand before the Lord of the earth. 5 And if anyone desires to harm them, fire proceeds out of their mouth and devours their enemies; and if anyone would desire to harm them, in this manner he must be killed. 6 These have the power to shut up the sky, in order that rain may not fall during the days of their prophesying; and they have power over the waters to turn them into blood, and to smite the earth with every plague, as often as they desire. 7 And when they have finished their testimony, the beast that comes up out of the abyss will make war with them, and overcome them and kill them. 8 And their dead bodies
will lie in the street of the great city which mystically is called Sodom and Egypt, where also their Lord was crucified. 9 And those from the peoples and tribes and tongues and nations
will look at their dead bodies for three and a half days, and will not permit their dead bodies to be laid in a tomb. 10 And those who dwell on the earth
will rejoice over them and make merry; and they will send gifts to one another, because these two prophets tormented those who dwell on the earth. 11 And after the three and a half days the breath of life from God came into them, and they stood on their feet; and great fear fell upon those who were beholding them. 12 And they heard a loud voice from heaven saying to them, “ Come up here.” And they went up into heaven in the cloud, and their enemies beheld them. 13 And in that hour there was a great earthquake, and a tenth of the city fell; and seven thousand people were killed in the earthquake, and the rest were terrified and gave glory to the God of heaven.
Rev. 13:1-18 pertains the Antichrist led fourth and final beast and the False Prophet he will employ. These scriptures pertain to when the Antichrist requires everyone to take his mark ignorer to buy or sell.
Rev. 13:1 And he stood on the sand of the seashore. And I saw a beast coming up out of the sea, having ten horns and seven heads, and on his horns
were ten diadems, and on his heads
were blasphemous names. 2 And the beast which I saw was like a leopard, and his feet were like
those of a bear, and his mouth like the mouth of a lion. And the dragon gave him his power and his throne and great authority. 3 And
I saw one of his heads as if it had been slain, and his fatal wound was healed. And the whole earth was amazed
and followed after the beast; 4 and they worshiped the dragon, because he gave his authority to the beast; and they worshiped the beast, saying, “ Who is like the beast, and who is able to wage war with him?” 5 And there was given to him a mouth speaking arrogant words and blasphemies; and authority to act for forty-two months was given to him. 6 And he opened his mouth in blasphemies against God, to blaspheme His name and His tabernacle,
that is, those who dwell in heaven. 7 And it was given to him to make war with the saints and to overcome them; and authority over every tribe and people and tongue and nation was given to him. 8 And all who dwell on the earth will worship him,
everyone whose name has not been written from the foundation of the world in the book of life of the Lamb who has been slain. 9 If anyone has an ear, let him hear. 10 If anyone
is destined for captivity, to captivity he goes; if anyone kills with the sword, with the sword he must be killed. Here is the perseverance and the faith of the saints.11 And I saw another beast coming up out of the earth; and he had two horns like a lamb, and he spoke as a dragon. 12 And he exercises all the authority of the first beast in his presence. And he makes the earth and those who dwell in it to worship the first beast, whose fatal wound was healed. 13 And he performs great signs, so that he even makes fire come down out of heaven to the earth in the presence of men. 14 And he deceives those who dwell on the earth because of the signs which it was given him to perform in the presence of the beast, telling those who dwell on the earth to make an image to the beast who had the wound of the sword and has come to life. 15 And there was given to him to give breath to the image of the beast, that the image of the beast might even speak and cause as many as do not worship the image of the beast to be killed. 16 And he causes all, the small and the great, and the rich and the poor, and the free men and the slaves, to be given a mark on their right hand, or on their forehead, 17 and
he provides that no one should be able to buy or to sell, except the one who has the mark,
either the name of the beast or the number of his name. 18 Here is wisdom. Let him who has understanding calculate the number of the beast, for the number is that of a man; and his number is six hundred and sixty-six.
