They are anti-Christ (not to be confused with THE Anti-Christ - the false Christ).
Note that "anti"-Christ can simply mean anyone who is "against" the true Christ, as in any "opponent of the Messiah" (Strong's Greek Dictionary, Word #500: antichristos), as in anyone who denies that Jesus is the Christ (1 John 2:22), or denies that Jesus is the human/divine Son of God (1 John 2:22b), or denies that Christ is in the flesh (2 John 1:7). The spirit of antichrist (1 John 4:3) has been working since the first century AD (2 Thessalonians 2:7), animating many antichrists since that time (1 John 2:18; 2 John 1:7).

And note that nothing requires that the future Antichrist (the individual-man aspect of Revelation's "beast") will ever claim to be the Messiah/Christ. For his antichrist denial that Christ is in the flesh (1 John 4:3) will disqualify him as a mortal-flesh human (under his Gnostic doctrine) from being Christ. Instead, the non-mortal-flesh Lucifer (Satan, the dragon) could be the false Christ (that is, the "Lucifer" Christ, and not the "Jesus" Christ: 1 John 2:22) during the future Antichrist's literal 3.5-year worldwide reign (Revelation 13:4-18, Revelation 12:9), which will be in the latter half of the future Tribulation of Revelation chapters 6 to 18 and Matthew 24.

But none of this means that there will not also be multiple, human false Christs who will arise during the future Tribulation (Matthew 24:24), including one who will be an ultra-Orthodox Jewish false Christ/Messiah. For shortly after the start of the Tribulation the Antichrist could "cut" a peace treaty with an ultra-Orthodox Jewish false "Messiah" (Daniel 9:26a, Daniel 11:22-23a) in Israel, promising this false Messiah and his ultra-Orthodox Jewish followers that they can keep for at least seven years (Daniel 9:27a) a third Jewish temple (Revelation 11:1) which they will have built on the Temple Mount in Jerusalem.
