Which people in the Bible are antichrists? Mormons have the view that antichrist refers to anyone who lives to deny/replace Christ. Korihor, Sherem, and Nehor are examples from the Book of Mormon; are there specific people from the Bible?

I got this question after reading this related question, where the idea that antichrist refers to "The Antichrist" (specifically one of the beasts in Revelation) is debated. Looks like the Bible (1st John 2:22) says antichrist just means someone who denies Christ. I like to be able to recognize antichist teachings, and I'm grateful the Book of Mormon points out prevalent ones in our day. I think the bible and book of mormon support each other, so again my question is specifically who has been an antichrist in the Bible? any specific examples? Specifically an answer from either Mormon doctrine or just what the Bible says.

I'm thinking Cain, and his idea that he didn't have to be his brother's keeper.
I think the only antichrist specifically identified from the bible is Lucifer, the great antichrist, as is mentioned in the link you've provided. 

You're right about Cain though, it is mentioned in the scriptures (Pearl of Great Price) that he loved Satan more than God (see Moses 5:13,18). This by definition makes him an antichrist. 

The link you provided lists all of the references in the standard works to all the other individuals who were specifically identified as antichrists. 

I imagine there could be more that fit the definition, but to my knowledge no one has yet put the work into identifying them all. I will speculate however that it could be debated that one other person who could be considered an antichrist is Judas Iscariot (see Luke 22:3). Judas is often regarded as a son of perdition, so I don't think it's much of a stretch to suggest he was also an antichrist.
