I used that picture of Kate because it was easier to fit into my comic cover idea.
Kate is the worlds greatest greatest Superheroine in the story...it's going to take a titanic battle for her to be defeated. Why do you want to see her lose ? What would you like to see in the fight ?
It'd be sexier to see her lose. All that pin-up girl pride and glory thrown out the window. Now that Kate Upton has gone into acting, imagine it like a scene from a new movie. I can picture it now:
1942. A tropical beach with blue skies and gold sand. This is where the two superwomen will meet up. Standing against the Eastern backdrop is Nemoto. From the West, wading through the ocean is Upton. Their chests billowing and bouncing powerfully against their tops as they slowly walk up to size one another. A calm ocean breeze blows their hair as they stare hatefully at one another. It is the start of the war and Kate is America's front line. She could end this war now by defeating Lady Kamikaze, especially if she can drop her "bombs" on her Japanese opponent. Thus, I imagine Kate Upton strikes first. Through the course of the fight, they will chase one another through jungle and river, finally ending in the mountains. Each time they move to a new location, the tide changes back and forth. It will be a 'catbattle' and not just a catfight.
This makes the fight more epic and dynamic.
Rob has the right idea. Kate should lose and kneel fearfully before her conqueror while Lady Kamikaze should stand on top of her/behind her with her own flag planted on the mountain for all to see (on the flag is Kate's top, dangling about pathetically). Then, maybe Nemeto marches her blonde captive around the Japanese camp or rides on top of her like a horse along the beach while a camera films them for propaganda purposes, Kate's top as a 'horse reign' around her neck (I figure Lady Kamikaze could use this as part of her "Toyko Rose" propaganda). Kate becomes Kamikaze's slave until she is freed later in the Raid at Cabanatuan ("The Great Raid").
And you mentioned it would take a "titanic battle" for Kate to lose. I agree. But I read your wording carefully and what I see is "
tit-tanic battle". Because there definitely should be a tit battle of epic proportions between both women. The contrast here is too great. East meets West. Red Sun meets American Star. Bright blonde haired blue-green eyes meets dark black hair, brown eyed Asian. Bust meets bust.
They're superwomen. Thus, when their boobs smash into one another....literally, the earth should shake, the seas should roar, waves should crash into the cliffs, and nearby mountains should crumble (this last one is a symbolic metaphor when Nemeto finally flattens Kate once and for all, breaking Kate's already straining bikini top). Perhaps in one scene, a small rainstorm occurs and thus, it allows the viewer/reader to 'see' through their tops. And then, their boobs crash into one another so hard (nipples touching nipples) that the rainclouds simply explode and spread elsewhere, opening up the blue skies and giving them both time to catch their breaths.
Otherwise, there will be the usual catfight fanfare. But adding a sense of superhero 'epic' to the story needs to happen.
