John 2:22-23 "Who is the liar but the one who denies that Jesus is the Christ? He is antichrist, who denies the Father and the Son. Whoever denies the Son does not have the Father; the one who acknowledges the Son has the Father also." This is someone who denies Christ as the only anointed one and refuses the interrelationship of the persons who are deity.
1 John 4:2-3 "By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God; and every spirit that does not confess Jesus is not from God; and this is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world." Several times this term is used in the plural, and can be applied to almost anyone who is opposed to Christ. Those who deny that Jesus came in the flesh are anti-Christ or of the spirit of antichrist. This is one of the ways to discern a false teacher from a true one.
John is writing after the resurrection and is using perfect tense in Greek which denotes a past action with continuing results into the present, and continuing on into the future. He came in the flesh, rose in the flesh, and is still in the flesh. The same body that He was born and died with, He rose with. If one claims that Christ rose as a spirit creature, and not physically, they are of the anti Christ spirit and are denying the third point of the Gospel. It was the Gnostics that John is specifically addressing in his epistles.
The word Anti can be understood to mean either against Christ or it can also means in place of , a substitute is the fuller meaning. He will be a substitute for the real one. In this way he opposes him.

I is antichrist :3

I absolutely agree from you. Likewise If we relate in Rev 13 the 666 is a number of a man who is ANTI-CHRIST or the BEAST. He is Abaddon (Hebrew) or Apollyon (Greek) the demonic king of the Abyss.II THES 2:3-6 Let no one deceive you by any means; for that Day [the return of Christ] will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God. Do you not remember that when I was still with you I told you these things? And now you know what is restraining [the Abyss], that he may be revealed in his own time.
This demonic king is the ruler of the fallen angels currently locked in the Abyss (Rev 9:1-11).///

From what I have read, he will make is appearance in the Middle East. And that comes from a very wide range of ancient sources.

To understand about the Antichrist, one must first separate the words and define them apart. Anti means against, and Christ means anointed. Since Israel is the most used entity
in the Scriptures as the anointed of the Lord, the Antichrist must be first and foremost an anti-Semite; an anti-Jewish person. Then, there are a few other characteristics.
