As much as I love Tengu as the next person does. I picked the following:
• Hitomi's Dad
• New Male
• New Female
Hitomi's Dad - He has high potential of being a possible fighter considering that he was Ein's master. While I tend to be adverse towards giving the same fighting style for the 3rd character. I think there is still a way for him to be different from Ein or Hitomi (probably by incorporating stances or expert holds).
New Male - There's a need to even out the 17:14 gender ratio this time considering 2 new females had been revealed to us with one of them already added officially to the roster. I think there's a lack of a lot of things under the male category (redheads or unusual hair colors, cheerful/energetic/spunky/ditzy personalities, ages around 18-19 years old, nationalities that doesn't fall under Japanese, Chinese or American).
Personally, I want what I had described. An 18 or 19 year old redheaded male (either Dutch, Swiss, Irish or Austrian) who is a Chinese Martial Arts practitioner (either Fujian White Crane or Meihuaquan for fighting style) with a ditzy/dorky personality (since a lot of the guys except for Bass, Brad and Zack are usually always serious) and I'd like it if he was a tournament character than a serious story character.
New Female - As usual this aspect can't be taken in out in a game that's always full of it. What I'd prefer to see is a female that will totally be the true ice breaker among them. A female that is visually an old biddy (a female Gen-Fu in a sense) meaning she has visible signs of aging appearance-wise like grey hair, wrinkles and crow's feet. I'd want her to be a 65 year old Puerto Rican utilizing Brazilian Jiu-Jitsu for fighting style participating in the tournament.
