1. Emilia Clarke - I think among this group, she's the Khaleesi of the bunch. Stronger then I think she looks, I think she'd be able to handle just about everyone else without too much trouble, besides maybe Kristin and Ariel.
2. Kristin Cavallari - I don't know too much about her but she seems pretty fit, I bet she'd be able to dish out punishment better then taking it, but she'd still be pretty formidable.
3. Ariel Winter - That chest of hers is probably her biggest strength and weakness, using it to bowl over her other small sized competitors but also a massive target (literally) on her chest.
4. Avril Lavigne - I think she'd have a lot of fight and energy in her, but it wouldn't take too much to sap that right out of her. I feel like she wouldn't be able to deal out much damage but would be pretty resilient.
5. Lilly Collins - Definitely don't think Lilly would fair well among this group, or any group to that matter. I think she'd have heart and that would keep her in a fight but she'd be nowhere close to winning except for if it was against No. 6.
6. Alexis Bledel - Though she's the tallest, Alexis always struck me as someone who would do anything to avoid a fight. And if in one, I don't think it'd be much of a contest. I think the only close contest she might have here would be against Lilly.
