Either Juri's got very little health or T. Hawk's Super does a crapload of damage. I think it did even more than his Ultra.
Back before info was revealed about her, I had an argument with a guy on Youtube who said Juri would be a clone of Kim Kaphwan simply because she uses Taekwondo. Looking back on it, it looks like he was partly on the right track - she's definitely not the same, but she seems to be very similar move wise - if it weren't for her low health, she's probably be a very good push character, constantly attacking, mixing up, and catching opponents of guard. That pinwheel and diving kick especially reming me of Kim.
Also, I noted that, in the interview, Killian referred to "boss characters," in the plural sense. Hint, perhaps?
