Identifying Prophecies of The Antichrist

"Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son."
1 John 2:22

So the Antichrist would deny Jesus as divine.

"In his place shall arise a contemptible person to whom royal majesty has not been given. He shall come in without warning and obtain the kingdom by flatteries."
Daniel 11:21

So he would appear to be thrust into power because of how much people like him.

"And he shall make a strong covenant with many for one week, and for half of the week he shall put an end to sacrifice and offering. And on the wing of abominations shall come one who makes desolate, until the decreed end is poured out on the desolator.”
Daniel 9:27

So he'll make a 7-year long treaty with "many," and halfway through, will make things desolate, and at Christ's return will be an end to him outlined in Revelation.
