Probably with the exception of some of the Harry-Potter Universe inhabitants.
Absent mother or father, asshole mother or father, or maybe both... adoptive parents, dead-before-you-knew-them parents, killed-in-your-lifetime parents, parents are sort of still around but you can bring them back from time to time by summoning their spirit.
And if both of your parents are fine and have a great life and raised you well, somehow you're made into The Bad Guy because you have everything and the main character doesn't. I don't know how that works.
