In order for this person to gradually be noticed by more and more people, there's going to have to be something about him that gets the buzz going.
More then likely, there are going to be things about him that fulfill various prophecies, after all, you can't be the " messiah " that people are waiting for if you're not. You may be able to fake it and get a small following, as evident by modern charlatans, but this man will be obvious beyond a shadow of a doubt, but at the same time, quiet, humble, and probably frightened as well.
These prophecies he'll fulfill will also include biblical prophecy, just as stated, otherwise it won't go down.
It's going to be much harder for religious people to handle it because he will fit biblical prophecy, but he won't fit the biased preconceived personifications that many have. This is something they will have to rectify, personally. So, since he's an everyday man, a " commoner ", he'll naturally and logically appeal to his peers first, then most religious folks will come around after the non-religious do.
This is even spoken of in Matthew 20:16
"So the last will be first, and the first will be last."
This is just one way god will teach us all a lesson at the same time.
Everything in the world is backwards, remember that when you ponder what you think an antichrist would be to the modern world.
And " Mr. Nobody ", if you happen to be reading this, I just want you to know that every little skeleton in your closet is going to be paraded in front of the entire world to scrutinize, every little dirty secret, everything good or bad you've ever done to anybody,..is going to be in the face of every man woman and child on this planet soon, so prepare yourself.
