@Awesmic I will expose my opinion about, but like it was already said this isn't the right topic to talk about Tekken and we are just derailing the thread.
Personally I think that the reason because Lucky Chloe is hated is simply because very iconical of some stereotypes from the Japanese side related to anime. Cat outfits and headphones are something that appear cute to the JPN fandom and even popular (immediately recalling to them other iconical characters that here could be unknown), while in the West are appreciated overall from who like anime because otherwise they will be very likely considered ridicolous.
I think that it's overall this one the reason because Harada ended to be pissed, not just for an excessive disliking of a character seen for a minute, but because maybe interpreting the excessive bashing like something addressed to the culture of his country (like various comments that I read indeed were doing). Usually Japanese people are tolerant toward other and recognize cultural differences: he is not asking to people to like this character, but just to be tolerant toward it.
Maybe is she a gift for the otaku fandom? In the West is she not so appealing? (thing that by the way is not so true, for me Japan has still not well realized how much anime and manga ended to influence the foreigner countries, but maybe in Europe the situation is different from the U.S.A). Very well, Harada said that other fighters will join the roster - aka should meet the tastes of people that now are unsatsified of Lucky Chloe - so let's be patient, very likely some next ones will not appear so good for the people that now like Lucky Chloe and in the end everyone could be ale to get a favourite fighter according to his different tastes. The numbers of the Tekken community are not the ones of DoA where you can be sure that adding a new female will make glad the majority of the fandom: the community of Namco's game is much more large worldwide, Harada and his team are not stupid and they know very well that can't only offer things easily likeable for the East; Tekken 6 is not only made of Alisa or Zafina, what about the more Western Miguel and Bob (and even if Japan like ambiguous characters, Eleonor seems to me very "Westernish "for being compared to similar examples in other franchises)?
About Lucky Chloe's personality and/or charisma, these are things very subjective and so far are related to really few seconds. From a side we lack of a full picture and in any cases this is debatable only until a certain point considering how everyone has different preferences. I agree with you that with the years Tekken developed always more and more comical reliefs for the role of many characters, and in part I miss the more serious atmosphere of the old games: by the way I believe that this is a sign of the times that change, inevitably people are now more attracted from similar backgrounds (however to be fair I can't say if I would like to keep constantly a serious tone).
However I can find uniqueness in the character and it's was just this the reason because other people complained more just about her and not other characters released so far. While far from being the only "crazy" character of the roster, Lucky Chloe shows an Eastern anime influence that can't be seen in the other characters. Liking it or less, it's this her individuality and the side of her character that has to get the focus for making her distinguishable: it's not important if she can appear as a "generic human idol", it's this that make her not generic in the roster. People can debate about the reasons or less to get a such character, but IMO not that she is generic because is instead pretty unique in realtionship to the context of her series (again, not necessarily something because people have to be fond of, only a consideration). This is exactly the same situation of Marie Rose in DoA, a gothic lolita like you can see in XYZ JPN works (I'm talking only about her appearence), but that is surely a news for the DoA series: if something the problem is why to introduce a such character if then you are not expanding her vestiary with outfits owned from such stereotypes, but actually this is a problem that is suffered in a different extent from all the females charas that get overall generic fetish outfits.
In conclusion I see all this "Lucky Chloe Crysis" (XD) something truly exaggerate and that in the end will not make nothing more if not to give even more attention and popularity to her - so exactly the opposite of the purpose of her dislikers. She is included in the genre cute/sexy female characters and is not the only new character of the roster, liking it or disliking it simply move on for the "next challenger": I see more important to discuss about the mechanics of the game, including or less a character will not be your key factor that will make Tekken 7 a game to remember or one to forget (and of course the same is true for all the other fighting series).
And for who say that Lucky Chloe is the worst character ever done for a fighing game, just my opinion but for me she is pure gold compared to this guy (no offense for his fans):
