lets just assume that because this show is for little kids that he doesn't have one and all children just appear like they do in the earlier versions of sims :P
not so sure about Originally but after that yeah, well mostly the games and card are for everyone of all ages for sure and yeah but it was on pc and i was a little kid back then so i dont remember much about the father part.
oh thank god i wasn't the only one wondering that! however i have no idea... but i've noticed that there are a few anime's where people either only have a mother or a father... it's really weird
Ruby/Sapphire want a word with you, Norman was the main character's dad ¬¬
For the rest of the series, I would assume the man is either a trainer or works all the time while the mum is a housewife and stays home incase you need something... I don't know ¬¬
Well You do but that's only in the Houen/Hoenn video games Ruby/Sapphire and Emerald where Senri-san/Norman is the player characters father but I think that's the only one where the player character has a father...like Haruka-chan/May did in the Pokemon anime..however in terms of why that's the only I'm not completely sure on that.
I think the cultural part might be a factor. In Japan taking care of children is a mother's duty, and this idea is still somewhat strong there, while the father is at work and absent. There are also many animes like that (the protagonist only having his/her mom), so they also seem to believe loosing a parent or both adds to the person's character because it needs to work harder to have what children with both parents have. It's not a general idea, it's just a common idea. I don't personally agree with these ideas, so this answer is really impersonal.
Hmm... that's a toughie, dude. Y'know, one theory is that the "Generations" thing might have somethin' to do with it. Like, Red is the father of that dude from Generation II or something like that. I mean, makes sense, right? The kid following in his old man's footsteps and becoming another great Trainer. At least, that's what I think.
