Who is Ash's dad? I've heard suggestions like Oak, Giovanni, Болталка travelling trainer and even (sickos) Ho-Oh, I personally think it's Giovanni, but I don't read the anime, so the answer might be there?
If Ты ask me, I think Ash's dad will never be shown. This is because (if Ты want my thoughts) His fauther left on his pokemon journey. When he was in the оранжевый islands, he was the 'chosen one' to collect the treasures. Then, at thunder island, he got fried by Zapdoes *people stare* ........ dont ask. I just made that up now
