In Christian eschatology, the Antichrist, or anti-Christ, refers to people prophesied by the Bible to oppose Christ and substitute themselves in Christ's place before the Second Coming. The term Antichrist (including one plural form) is found five times in the New Testament, solely in the First and Second Epistle of John. The Antichrist is announced as the one "who denies the Father and the Son."
The similar term pseudokhristos or "false Christ" is found in the Gospels. In Matthew (chapter 24) and Mark (chapter 13), Jesus alerts his disciples not to be deceived by the false prophets, who will claim themselves as being Christ, performing "great signs and wonders". Three other images often associated with the singular Antichrist are the "little horn" in Daniel's final vision, the "man of sin" in Paul the Apostle's Second Epistle to the Thessalonians, and the Beast of the Sea in the Book of Revelation.
