dawn - i only saw and hear about her mom...

ANSWER = probably May

I have not followed the series since when it was originally cool (first few seasons). I know Ash does but you never see him, he is mentioned and is a gym leader. However I have no idea about May and Dawn. All of them literally have fathers, but in their lives it would be Ash unless there can be multiple answers.

B.) May. In the series, Ash's father was mentioned once, but Dawn's was never mentioned. May's father is a Gym leader and he was actually seen in the anime, but Ash and Dawn's father never appeared.

B.) May's Dad is a gym leader. Ash's Dad was mentioned but not seen. Dawn's dad as never mentioned

D.) All of the above.

Ash ?
