I don't know much of anything about the 12th Imam other than the Iranian leader seems to be looking forward to his return or appearance or whatever.
If Islam says that that guy and Christ will come back and "rule" that is interesting because the Christian bible indicates that Christ will return physically, but this will be after the Anti-Christ and the False Prophet run things for the tribulation period.
They will be apparently be able to control the masses w/the "mark of the beast" requirement needed to buy and sell anything. This type of technology is here already.
Here this should help re: biblical prophecy stuff (gotquestions.org):
Question: "What is going to happen according to end times prophecy?"
Answer: The Bible has a lot to say about the end times. Nearly every book of the Bible contains prophecy regarding the end times. Taking all of these prophecies and organizing them can be difficult. Following is a very brief summary of what the Bible declares will happen in the end times.
Christ will remove all born-again believers from the earth in an event known as the rapture (1 Thessalonians 4:13-18; 1 Corinthians 15:51-54). At the judgment seat of Christ, these believers will be rewarded for good works and faithful service during their time on earth or will lose rewards, but not eternal life, for lack of service and obedience (1 Corinthians 3:11-15; 2 Corinthians 5:10).
The Antichrist (the beast) will come into power and will sign a covenant with Israel for seven years (Daniel 9:27). This seven-year period of time is known as the “tribulation.” During the tribulation, there will be terrible wars, famines, plagues, and natural disasters. God will be pouring out His wrath against sin, evil, and wickedness. The tribulation will include the appearance of the four horsemen of the Apocalypse, and the seven seal, trumpet, and bowl judgments.
About halfway through the seven years, the Antichrist will break the peace covenant with Israel and make war against it. The Antichrist will commit “the abomination of desolation” and set up an image of himself to be worshipped in the Jerusalem temple (Daniel 9:27; 2 Thessalonians 2:3-10), which will have been rebuilt. The second half of the tribulation is known as “the great tribulation” (Revelation 7:14) and “the time of Jacob’s trouble” (Jeremiah 30:7).
At the end of the seven-year tribulation, the Antichrist will launch a final attack on Jerusalem, culminating in the battle of Armageddon. Jesus Christ will return, destroy the Antichrist and his armies, and cast them into the lake of fire (Revelation 19:11-21). Christ will then bind Satan in the Abyss for 1000 years and He will rule His earthly kingdom for this thousand-year period (Revelation 20:1-6).
At the end of the thousand years, Satan will be released, defeated again, and then cast into the lake of fire (Revelation 20:7-10) for eternity. Christ then judges all unbelievers (Revelation 20:10-15) at the great white throne judgment, casting them all into the lake of fire. Christ will then usher in a new heaven and new earth and the New Jerusalem—the eternal dwelling place of believers. There will be no more sin, sorrow, or death (Revelation 21–22).
