The 'real' Antichrist began with fallen apostles and culminated with popes on vatican throne. No world leader will emerge. 2Thes2

" Young children, it is the last hour, and, just as YOU have heard that antichrist is coming, even now there have come to be many antichrists; from which fact we gain the knowledge that it is the last hour. 19 They went out from us, but they were not of our sort; for if they had been of our sort, they would have remained with us." 1Jo2:18


'However, brothers, respecting the presence of our Lord Jesus Christ and our being gathered together to him, we request of YOU 2 not to be quickly shaken from YOUR reason nor to be excited either through an inspired expression or through a verbal message or through a letter as though from us, to the effect that the day of Jehovah is here.
3 Let no one seduce YOU in any manner, because it will not come unless the apostasy comes first and the man of lawlessness gets revealed, the son of destruction. 4 He is set in opposition and lifts himself up over everyone who is called “god” or an object of reverence, so that he sits down in the temple of The God, publicly showing himself to be a god. 5 Do YOU not remember that, while I was yet with YOU, I used to tell YOU these things?
6 And so now YOU know the thing that acts as a restraint, with a view to his being revealed in his own due time. 7 True, the mystery of this lawlessness is already at work; but only till he who is right now acting as a restraint gets to be out of the way. 8 Then, indeed, the lawless one will be revealed, whom the Lord Jesus will do away with by the spirit of his mouth and bring to nothing by the manifestation of his presence. 9 But the lawless one’s presence is according to the operation of Satan with every powerful work and lying signs and portents 10 and with every unrighteous deception for those who are perishing, as a retribution because they did not accept the love of the truth that they might be saved. 11 So that is why God lets an operation of error go to them, that they may get to believing the lie, 12 in order that they all may be judged because they did not believe the truth but took pleasure in unrighteousness." 2Thes2
