Antichrist characteristics:
1. Does not regard the desire of women, making him celibate or homosexual.
2. Will have a fierce countenance or a stern look.
3. More stout than his fellows, more proud and boastful.
4. Master of political intrigue and a military genius. Jerusalem will be an international city accepting Islam, Christianity and Judaism. Three and a half years into his reign he will break his covenant and invade Israel from the north. He will make Jerusalem his world capitol and outlaw all religions, except the worship of himself and his image, sitting in the temple declaring himself to be God.

It's all in the Book of Daniel chapters 7 and 8.
