As with most things Judeo-Christian, there are varied opinions. And while I respect Jesus, I’m not a Christian.
But anyway:
‘The Antichrist will be history's vilest embodiment of sin and rebellion: “Don't be fooled by what they say. For that day will not come until there is a great rebellion against God and the man of lawlessness [sin] is revealed—the one who brings destruction.” (2 Thessalonians 2:3 NLT).’
And:
‘According to biblical prophecy, the Antichrist is recognized as a charismatic global leader who emerges during a time of crisis, promoting a "counterfeit" peace while acting as a "man of lawlessness". Key signs include denying that Jesus is the Christ, demanding worship, blaspheming God, and enforcing a mandatory mark for economic control.’ -AI Overview
Profile of the Antichrist
“And I looked, and behold, a white horse. He who sat on it had a bow; and a crown was given to him, and he went out conquering and to conquer” (Revelation 6:2 NKJV).
Some have confused the rider of the white horse in this verse with Jesus, but the rider is actually the Antichrist. It is true that Jesus comes on a white horse, but this rider is not the same as the description of Christ in Revelation 19.
For following the appearance of the rider is not a kingdom of righteousness—as with Christ’s return (Revelation 19:11–13; 20:4)—but a time of wickedness and sorrow. Masquerading as the true Messiah, he wears a crown, while Jesus wears many crowns (Revelation 19:12). In the Greek translation, the crown worn by the rider of the white horse refers to the crown of victory worn by a conqueror. The crowns Jesus wears in Revelation 19 refer to crowns of royalty.
Furthermore, Antichrist carries a bow without arrows; Jesus Christ has a mighty sword. Antichrist initiates war; Jesus comes with his armies at the battle of Armageddon and ends war. Antichrist inaugurates the Great Tribulation period; Jesus Christ ends the Great Tribulation period.
A Conqueror Bent on Conquest
The Antichrist will deceitfully establish himself, and then show his true colors.
This coming world leader, the Antichrist, will come at an economically difficult time. There will be war in different parts of the world and he—through brilliant political moves along with an incredible charisma—will be able to do what no one else has ever done: bring economic stability to the world’s monetary system and bring world peace.
By establishing this peace, he will deceive many. He will even convince the Jewish nation and the Arab nations to sign a peace treaty, paving the way for the long-awaited third temple.
His accomplishments will be so spectacular, so far-reaching and unprecedented, that many will hail him as the Messiah. But we are warned in Scripture that he is a deceiver (Daniel 8:25). ‘
