“The Beast
In Revelation 13:5-8, the antichrist is referred to as “the beast:”
“Then the beast was allowed to speak great blasphemies against God. And he was given authority to do whatever he wanted for forty-two months. And he spoke terrible words of blasphemy against God, slandering his name and his dwelling—that is, those who dwell in heaven. And the beast was allowed to wage war against God’s holy people and to conquer them. And he was given authority to rule over every tribe and people and language and nation. And all the people who belong to this world worshiped the beast. They are the ones whose names were not written in the Book of Life before the world was made—the Book that belongs to the Lamb who was slaughtered.” (NLT)
We see “the beast” used for antichrist several times in the book of Revelation.
The antichrist will gain political power and spiritual authority over every nation on earth. He will most likely begin his rise to power as a very influential, charismatic, political or religious diplomat. He will rule the world government for 42 months. According to many eschatologists, this time frame is understood to be during the latter 3.5 years of the tribulation. During this period, the world will endure a time of unprecedented trouble”

It’s implied that he will be charismatic, as so many people will be willing to follow him, even to the point of literally worshipping him. To me, we can see the seeds for this being sown in the way mass media, such as never existed before in history, even now entices people to follow celebrities, as a herd of sheep follows a shepherd.
Unfortunately, what begins as voluntary worship by the majority ends being mandatory worship required of every single living soul.
From the article:
“Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world. By this, you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming and is now already in the world.”
It appears we can rule out any one who confesses that Jesus Christ has come in the flesh, which implies he will not be Christian.
You wrote,
“It’s implied that he will be charismatic, as so many people will be willing to follow him, even to the point of literally worshipping him.”
And from the article:
“The antichrist will gain political power and spiritual authority over every nation on earth. He will most likely begin his rise to power as a very influential, charismatic, political or religious diplomat.”
So, it is not actually written that he is charismatic, but implied?
Rev 13 says he has the mouth of a lion (he speaks great blasphemies), has great authority (he has power over all the world), and he makes war with the saints. Could he not also be a ruthless dictator and achieve the same results?
