I agree. Larxene may have more balls than most of the men, but she's highly feminine otherwise. The drama queen movements, the, while scary, giggling, one hip out poses, she even traces her hair, etc. Her flirting, her female arrogance. Hell, even her render has the typical model pose, except with...knives.
As for Xion, my previous sentiments of her remain true until some upcoming title makes her role worth something than a minor aspect of Roxas that could've been explained otherwise. Xion is Sora's memories, the missing "chain" to flow with the rest, but in the end, she returned to him/them, making it go back to square one no matter what happens: Roxas needed regardless. So all that only for things to be left the same with or without the unneeded complications added? (even the whole thing with Deep Dive was, whether or not she spoke to Riku, he would have stopped Roxas no matter what the cost for the personal reason as to why he was there in the first place: Sora. Surely not to enjoy the view of the skyscraper). Granted, they had to be careful, but you really don't need Xion overall as of now. Everyone forgetting her, while predictable, makes Days severely contrived, especially since the game revolved around her mostly. With that gone, there's nothing left for any character in the future to refer to. Who's going to mention her other than, those who might or might not remember? Not Axel, not the Organization, Xemnas by the way of his notes, perhaps, if he kept one. But I doubt it would make an impact anymore. Even Sora might have recalled CoM at the end of KH2.
Not only did Nomura say it might be difficult to bring Xion back in because of the existence, but he expanded in an interview that Roxas didn't really inherit her keyblade, but awoke something within him for it. Which makes it all the more loose than it was previously that other things may have triggered it depending. As well as the fact that most of the connections to BBS are not centered on her minus that time when Xigbar saw her as Ven. Her creation for the mere fact of sympathizing until the finish won't make her suddenly my favorite either (takes a lot for me to cry, KH has yet to do that). Her personality was also very, very typical. Here we have someone else who's cute, shy, nice, a sweet, sacrificial, and awwness. It was like a mixture of Kairi and Naminé. Even Olette had more originality in character to be seen. Her story also screamed of KH2 Roxas nestled with Riku Replica's story, to even dying in someone's arms (I swear, if Riku Replica wasn't a guy and adorable, there'll be more "nuuuu T_T", cause his fate was much more awful :/), except the difference was Xion's choice in the end, and how it was done. Xion was truthfully meant as a character that doesn't directly affect things if she never existed, or existed, to round it up. Won't hold it against them: it's not like they could have done anything else in case it clashed with the sequel. It's the way of retconning, even if it was the decision in the first place.
Otherwise, her character goes to the "neutral" category with Kairi. Not enough to impress(yet), but not worth any hate. I honestly have yet to hate any KH character. Epic game, though. It covered a lot of other stuff away from the ones above.
