Meg Griffin is a daughter of Peter Griffin in the show Family Guy. She is ugly, and completely unloved. Trust me, she deserves it.
Meg's appearance has never changed, except for in one episode.
However, much about her has changed over the years. In season one, Mila Kunis was not the voice of Meg, but took over in season two, and has been the voice ever since. Also, in Seasons 1-3, Meg was not really on the receiving end of so many jokes
Yes, she was whiny, fickle, and obsessed with being popular (wow, sounds like all women), but she wasn't really hated.
Peter hates Meg.
Lois hates Meg (though she does sometimes give Meg Advice).
Chris seems okay with Meg (going to her for advice).
Stewie hates Meg.
Brian is usually too drunk to give a shit.
And, Quagmire wants to bang Meg (along with any other
Cleveland also quips Meg is "My least favorite of your children"
Meg usually responds to this by saying "I hate you" or threatening suicide, which Lois sometimes seems to encourage.
MIla is actually from Ukraine, and has been in several movies.
However, after seeing her in American Psycho 2, starring with William Shatner, I was horrified and gouged my eyes out. I have yet to see her in a movie since.
Beyond that, Mila was also in That 70's show. Go figure. Does that make an odd link to MacFarlane's daughter character in American Dad? Wow. I think I just found a conspiracy.
