“Then the beast was captured, and with him the false prophet who worked signs in his presence, by which he deceived those who received the mark of the beast and those who worshiped his image. These two were cast alive into the lake of fire burning with brimstone.”
Revelation 19:20 

So what happens to the Antichrist and the false prophet during the battle of Armageddon? The Lord captures them both and throws them alive into the lake of fire.

Finally, Jesus Christ deals with Satan. Revelation 20:1-3 says, “Then I saw an angel coming down from heaven, having the key to the bottomless pit and a great chain in his hand. He laid hold of the dragon, the serpent of old, which is the Devil and Satan, and bound him for a thousand years; and He cast him into the bottomless pit, and shut him up, and set a seal on him, so that he should deceive the nations no more till the thousand years were finished.”

Remember that Satan is a defeated foe! He has no jurisdiction over your life. You can resist him and his antics!
