Ohh, I’m gonna get roasted for this. Maybe even Pitted considering some of the Whedonites here.
Buffy.
Cute young girl early on in the series, but crazy ass angry bitch by the end.
Awesome? Yes, of course. But if someone said that she was coming over to my apartment with a bottle of champagne and edible undies, then I’m packing my bags. Good Christ, I wouldn’t last the night!
Dawn & Willow = Yum!
Buffy = Yikes!
Make it three. By the end, they looked leathery, hungry and bitter. And the men were sort of bloated and badly dressed.
Mine is Laura Prepon, who started “That 70s Show” as a stunning redheadand ended up as a generic, harsh looking blonde. Something went amiss with her skin–she originally had an amazing creamy complexion with pillowy lips but she got all haggard and her skin harshened something awful. Going blonde was a bad move for her, the color really doesn’t suit her complexion at all and it just looks brassy. Maybe she lost too much weight and forgot her sunscreen but dayam! Real pity, too.
Exactly who I was going to mention. At least they can work her plastic surgery into the character and get a few cheap jokes out of it.
Christa Miller from The Drew Carey Show? Damn, I hate to hear that. She was hawt.
Good choice…it was so disappointing when she went blonde. Hmmph. At least Kari from Mythbusters hasn’t changed. 
I’m going to say Xander from “Buffy.” I don’t think he was supposed to be the hot guy per se, but when I first started watching, he was extremely tasty, with those big brown puppy dog eyes (plus, anyone remember the swim team episode? Yowza!). By the end of the series, he had gained about 50 pounds, had some kind of weird greasy do, dressed only in ill-fitting oversized clothes, and gotten a strangely large upper body (and, of course, there’s the eye thing).
Leah Remini put on weight when she had a baby.
I’m as Whedonite as one can get and I fully agree with you. Buffy was hot in the early seasons of the show. By season 7 it was like just get this shrill harpy off my screen. She had stopped wearing the tight leather pants and the short skirts and she had lost too much weight to be considered really attractive anymore. She’s the one I came in here to post about.
Sally Struthers was a hottie when All in the Family began. She was verging on frumpy when she left the show about 7 years later.
Another victim; Diane Neal of Law & Order: SVU.
Jaleel White was pretty hot, un-Urkeled. He guest starred once as Ashley’s boyfriend to whom she almost loses her virginity on Fresh Prince of Bel Air.
This is obviously a relative term, because you’re discussing a tv character that hasn’t been shot for over 20 years, but everyone here is aware of. That’s some pretty good success.
Yes, I know it was cheesy. I can’t even really watch it anymore.
William Peterson on CSI has gone from early-seasons handsome to middle-seasons holy-christ-I’ve-let-myself-go to current-season okay-I’ve-learned-how-to-stabilize-my-weight-again handsome.
You stole mine. Laura Prepon used to be in my “list of five”, now she wouldn’t even make my “list of fifty”. The blonde hair just makes her look… not right.
Just a little tip from my experience: don’t google “hot lips” in google images without switching ‘safe search’ on. MY EYES!!!
Sara Rue on Less than Perfect. She lost way too damn much weight!
I’m not convinced that Christa Miller has had any surgery at all. She may have had Botox, but I always thought that really only her character Jordan had Botox and Christa was only acting (though perhaps method acting) the effects. When she appears in the behind-the-scenes stuff on the DVDs she seems to look perfectly normal to me.
I have often wondered if she were made up to look as if she had surgery. I have always hoped so, because she is way more attractive natural.
This must be a “whoosh.” She went from repulsive to genuinely hot when she dropped all that weight.
