Natsu: Zeref's Son?

[Lizeron]

I believe time travel will happen. not 400 but 14 years ago. 14 years would make way more sense, wouldn't it? They have a chance to save Lucy's mom and prevent the dragons from going into hiding. And similar to the rest of the theories here, this would give some feedback Zeref looking at a younger Natsu.

Nothing in Natsu resembles Zeref. Nothing at all. A relationship would be too unlikely xD! I will admit that while on the Tenrou island, I thought Zeref was a grown up Romeo xD! Irrelevant is irrelevant, but I see way more similarities there !

I would say it is possible , it would explain why he left Natsu ; as he knew he had done wrong instead bringing up the only one to defeat him to be a dark wizard like himself he will leave natsu in the hands of a dragon

Finally, I have one last connection with Zeref and all those things but this one is more far-fetched. Since Natsu/Wendy/Gajeel seem to be chosen child and since Igneel/Grandeeney/Metalicana seem to be trainers of an extinct breed, perhaps they all come from the past. Maybe that's why Natsu/Gajeel got those extensive age (time-travel?!?)... Let's say that 400 years ago, Dragon Civil War was nearly ending and that Igneel/Grandeeney/Metalicana were last survivors from the wrath of Acnologia. Similar to how Exceed's eggs were thrown into an Anima, those 3 dragons took 3 kids with them and travelled to the future. For some years, they trained those kids into Dragon Slayers, in the hope that one of them will turn out powerful enough to defeat Acnologia. In year X777, they sensed that Acnologia tracked them down into the future and they fleed away. If Natsu/Wendy/Gajeel come from a distant past, we may understand why Zeref know Natsu. Perhaps he is Natsu's biological father. After all, he had tears of joy when he saw Natsu - similar to what a father could have for his son. Or another idea that since Cali pointed out about fire magic on tapestry, perhaps, Natsu is the son of human Acnologia...
Well, I guess I was right on the dragons that were going to be revived in the past chapters...So, as I explained in that, yes, I do believe that there's a possibility of Natsu being either Zeref or Acnologia's son.

GENIUS!!!!! , i will go by this now

I think Zeref and Natsu have a connection together, also because of what Zeref said "you've really grown" and also the scarf that he did get from Igneel saved Natsu. So Igneel know of Zeref power and he knew Natsu would meet him someday, maybe that is also why he did give Natsu the scarf so he would find some protection against Zeref. and maybe that is also why only natsu could/can defeat him.
