Considering that every mention in the New Testament of Anti-Christ tends to talk about "they " and "them" rather than a singular; the only singular Anti-Christ is the final one in the John the Revelator's writings which pretty much referred to Nero.
Here's my free lecture based on 58 years of having read the Bible in various forms (I got bored one summer while my parents were working and read the entire KJV at home, a 1920 version with cool Victorian plates and annotations when I was 9...)
1. According to the Apostle Peter and following teachers of Christianity, an "Anti-Christ" is someone who sets himself (or herself) as a Prophet claiming to speak for the Christ or continue Christ's message beyond the accepted teachings
(Sorry Muslims, even though Jesus is a respected Prophet teaching "God's Mercy", Christians think it stopped there; you can blame Nero and the several itinerant Roman and Greek Antichrists making their Profits ...)
2. The world was supposed to end "soon" (a hundred years or so) after the Crucification, so everyone was supposed to be celibate so as to be pure when Jesus called his flock home. You were only supposed to get married if you absolutely couldn't stand to be celibate or not masturbate.
3. Hell really isn't described as a final destination for anyone who wasn't seriously, joyfully evil. Purgatory is implied.
4. All of the early Christian teachers were not univocal and contradicted each other; heck, all versions of the Bible aren't univocal and they all contradict themselves, so your (or your society's) interpretation of a Christian Bible will always be personalized to forward whatever agenda best represents or is most advantageous. An Anti-Christ is one who forces everyone else to live by his original her interpretation or expansion on the Bible.
There, that's my lecture on Anti-Christs. Only difference is I'm not rich, connected, and arrogant, so few people will pay to listen to me.
