Kazuya is quite easily the smartest among all Mishima,the type of nerd who has highest grades in the class but manages to have debates with teacher and gets told to get out of the class for beating teacher in his own domain.
Lee isn't really a Mishima so don't try to mention him. Lee is more creative and has more inventions than Kazuya,while Kazuya is more strategic and farsighted than Lee. It's like "Scientist" vs "Mastermind".
Sliiiiight nitpick, but I feel like Namco always has Mari Shimazaki make her most basic designs when it comes to Tekken 😅
She's made Bayonetta, of course, and she's even made some killer designs for Leixia's 1P and also Ivy's and Tira's SoulCalibur V 2P designs but her work for Tekken?
Josie is literally just the Filipino flag and an ugly haircut.
Kazumi is just a woman in a kimono, worn in the way dead people wear it in funerals and an old-time-y haircut, but don't forget the bows! Because no woman in Tekken should look older than 16!
And now Reina, she is admittedly her best Tekken design so far, I like the hoody, but the hair is kind of a mess and it's otherwise just too... Plain.
Like, I don't know, I guess she doesn't have to go all out all the time but I was genuinely, unpleasantly surprised when I heard she was responsible for Josie's look and while it's nowhere near as basic with Reina, it's too pre-Tekken 4 plain for me.
