>>I'll stick with the Bible. <<
Even some "bible Christians" infect their faith with Zoroastrianism. Stick to your bible, but beware your preacher if you would remain ignorant of Zoroastrianism. Hint: the concept of a personified anti-Christ who wages war against Christ appears nowhere in the bible. There is no mention of an anti-Christ in any biblical apocalypse account, including the entire book of Revelations.
The only references to an anti-Christ appear in the epistles of St. John.
1 John 2:22, 2 John 1:17 and 1 John 4:3 define an anti-Christ as anyone who denies Jesus Christ has come in the flesh.
1 John 2:18 states, "even NOW (i.e., 1st-century!) there are MANY anti-Christs."
None of these references are epistological (apocalyptic), all simply use anti-Christ to mean ordinary people who oppose the gospel.
So where did we get the notion that there was a supernatural opponent of the God of Light who would be born into the world and make war against the God of Light? It's a blending of Zoroastrianism, non-canonical Jewish mythology, and Christian speculation.
Some people believe that one of various characters in Revelations are the anti-Christ. I don't have time to refute each one, (although if you have specific concerns about one, I can get you some more info.) But neither the beast, the dark prophet, the serpent, nor the whore fit the mythology around the "anti-Christ."
