There is that one singular individual who will become the Antichrist, but it will not be that he will a false christ, such as persons coming in Jesus's name, i.e. claiming that they are him (Jesus).
examples of "false christs" are Hosea Miranda (deceased), John Miller of Australia, Vissarion of Russia.
Instead, the Anti-(Jesus) Christ will be a person who the Jews will embrace as being their long awaited messiah. "the" messiah in Biblical terms is the promised great King of Israel, God would send to lead Israel and the world into the messianic age of peace and safety, among other things.
"Anti" means instead of and against. The person who becomes the Antichrist - by being anointed the King of Israel by the Jews will be instead of and against Jesus - the rightful King of Israel.
When the person, in the role of being the King of Israel, without warning, commits the act in 2Thessalonians2:4, the transgression of desolation, revealing himself as the man of sin - that will effectively end his time as the Antichrist, as the Jews mortified over his action will reject him from continuing as their King.
The person will be killed for his action (Ezekiel 28:1-10) and subsequently brought back to life in Isaiah 14:19-20, after a short time in hell. When the person is brought back to life by God who does so because of His disdain for the person, the person takes on the persona as the beast - which Revelation refers to him as.
So it is essentially wrong to call the person in Revelation 13, the "Antichrist" because he will no longer be in that role. Just as a reporter would not refer at a presidential news conference, to address the President of the United States as Senator. Different roles.
That person goes through different roles, is essential to understanding the end times.
The roles are.....
Fist as the little horn, leader of the end times Roman Kingdom - the EU, then as
The prince who shall come (to the middle east), then as
The Antichrist, illegitimate anointed King of Israel, then as
The revealed man of sin, then as
The beast of Revelation
Revealing himself as the man of sin - is the transgression of desolation (Daniel 8:13) - triggering the Day of the Lord.
Shorty thereafter (we are not given as timeframe), the person after being killed and brought back to life as the beast, and the image made of him in Revelation 13 -
The image of the beast - is the abomination of desolation (Matthew 24:15) - triggering the Great Tribulation.
The image of the beast will be incarnated by Satan, making it appear to have life - which everyone will be required to worship. The beast on the other hand is some forth coming man, who goes through those roles. The last role being that of being the beast.
