Why is it when women are made into sex objects they look so...stupid?

I've been playing Hyrule Warriors on Wii U for about a week now and I've been enjoying it. I was a bit hesitant to buy it at first because I was unsure if I would enjoy it but it's been a pleasant surprise. It's enjoyable (but slightly repetitive) and difficult enough without being too hard I want to give up on it. One thing that annoys about it is this person....

This is the baddie of the game. Her name is Cia. Just...look at her. Look at those breasts. You can tell she was probably designed by a man. Her poor back. And just think of the trouble she has shopping for bras. Just look at the poor woman. She can't even find a sexy evil witch outfit that fits properly. I like to have my ladies supported not hanging out like that. One of the things I've always liked about Nintendo games is that the women in them (and they're aren't many) have never looked like her. The female characters in Nintendo games have always been very children friendly. Peach is a terrible character. She's more of a plot device than a well fleshed out character. She exists to be kidnapped. She's a terrible cliche, unoriginal, and boring. Rosalina, the princess from the Galaxy games, is cooler. She doesn't get kidnapped and controls the little Star creatures. She helps Mario and is not just a victim. Rosalina and Peach may be boring and background decoration but at least they don't prance around in their underwear and have breasts bigger than their heads.

Now look at the character of Samus...

This is one of her outfits in the upcoming Smash Brothers Wii U game. Why is she fighting in her underwear? SIGH. What's stupid about her fighting in her underwear is Samus usually wears a suit of high tech armor. If you had a robot suit that fired weapons why would you ditch that and fight in your knickers? I don't have a problem with women being sex objects from time to time. But why oh why do they have to be so unrealistic looking? I mean look at Cia. What's with the breasts? The female characters in the Legend of Zelda universe are some of the better female Nintendo characters. Unlike Peach Zelda has magic powers, can fire a bow and fight with a sword, and ride a horse. She still gets kidnapped a lot but most games usually end with her joining Link and helping him to defend the villain. Without Zelda Link would not be able to win.

And then there are characters like Impa. Look at her.

This is her in Hyrule warriors. How cool does she look? The thing I like about her appearance is she isn't unrealistic looking (although the size of her sword is). She hasn't got super thin high legs, an impossible waist, giant breasts and a huge butt. Oh and her outfit doesn't highlight her boobs and butt and actually covers her body. Why is it so hard to portray realistic women as sex objects? Why does Cia's breasts have to be so stupidly big? And why does so much attention have to be on her breasts? I think it's laziness. It's just the opposite end of the spectrum from Peach and Rosalina. One of the things I like about the Legend of Zelda is how the women in it are powerful, strong, but not defined by their looks. With Zelda it's her strength and power and with Impa it's with her skills as a warrior and loyalty to the princess.
