Based on the way they look: Tied between Axel and Zexion
Based on their Character in general: I like Larxene
By name: Larxene again
By weapon: Xaldin
Ya Muffinman!! I totally agree. I like Larxene the best. I have a tendancy of picking out the odd one out of the bunch (she's the only girl unhooded so far).
By weapon...hmm, I would have to say Marluxia and Larxene. There weapons are kick-@$$. I love Marluxia's scythe; with all the zoominess and the ability to slice you right in half. Reminds me of the Sectumsempra curse Harry used on Malfoy in HP:HBP. Yikes. I like it when Larxene uses her Lightning daggers. When she goes into attack position, she looks all ready to have a fiesta: you know, it looks like she's holding castanets? LOL
