BEWARE THIS CONTAINS SPOILERS
He has been searching a flower Pokemon from 3,000 years.
Many rumors have been telling that he is Ash's father. Why?
Ash's father never came and Ash went to so many regions.
Ash's father also went to a Pokemon Journey that nobody knows about.
See? This all is related to AZ so much!
I really want to find the mystery of this Pokemon Trainer AZ.
When you finish the game, Sycamore makes you ride a parade and suddenly AZ comes in between.
He challenges you and says and says that he wants to see a 'real' trainer.
Once you won, he thanks you for showing a real trainer.
Then,suddenly the Pokemon which he was searching from 3,000 years comes from the sky and lands to AZ's hand.
The Pokemon is actually the evolution of Flabebe.
So there was the story. I found this very interesting and I think that AZ is Ash's father.
You can get ALL the details about AZ on Serebii. I did not copy paste because you guys will think that I am a copier.
So guys, should AZ be declared as Ash's father?
I am waiting for the episode in which Ash meets AZ

So vote.
Hope I get more news and I share it with ya guys.

Master Blaster,
Vici.
