Well first of all, Nero didn't satisfy everything about the beast of a man who will rule.
One basic fact of prophecy is that the destruction of the Temple in A.D. 70 points to the people from whom the final ruler will come. Since Nero ruled prior to that; he is eliminated from being THE beast of a man we speak of in THE anti-Christ.
Daniel 9:26 After the sixty–two ‘sevens,’ the Anointed One will be cut off and will have nothing. The people of the ruler who will come will destroy the city and the sanctuary. The end will come like a flood: War will continue until the end, and desolations have been decreed.
Still, there is a passage after the parallel account of the one 'seven' in Revelation chapters 13-16 (inclusive) in the explanatory chapters of 17 and 18 which may include Nero.
Rev 17:3 Then the angel carried me away in the Spirit into a desert. There I saw a woman sitting on a scarlet beast that was covered with blasphemous names and had seven heads and ten horns.
9 “This calls for a mind with wisdom. The seven heads are seven hills on which the woman sits. 10 They are also seven kings. Five have fallen, one is, the other has not yet come; but when he does come, he must remain for a little while.
Looking from God's timeless aspect from Heaven, but at the time of the end as presented in John's visions as God gave them to him, we can look at the seven heads as being seven kings.
At the time of the end, five have fallen. Nero might very well be one of those. Hitler would be the first candidate on my short list of possibilities for historical tyrants who were opposed to God fundamentally, Stalin and Napoleon would be other candidates...
The sixth is the anti-Christ, the ruler who will come, and the Bible is consistent in point to a Roman ruler, from the statue of Nebuchadnezzar, to the seven hills of Rome, to the people who destroy the Temple (actual building) in Daniel 9.
The seventh in this timeline view would be the one who is raised up for only a little while at the end of the Millennium.
So a literal, futuristic interpretation can logically be made from Scripture.
