I think she looked prettier in her appearances in Tekken 2 and tekken tag.
I hope they don't bring her back for Tekken 7 to join Jin, Kazuya and Heihachi comedy trio.
IF she were brought back:
a) She'd be a messenger from the afterlife to prevent a greater evil, and would return to the afterlife in the end.
b) Would some how just be alive and be a mentor to guide Jin, and make sure Asuka would continue to be awesome.
c) She'd be corrupted by evil, ala Jinpachi, and be the final boss of the game.
c) would be awesome, actually.
Either way, the Mishama trio joke started recently anyway. I mean if you look at Heihaci in Tekken 3, he tosses Jin into a volcano without hesitation or joke.
Lee will probably continue being that Dan Hibicki of the game. He'll never compare to Dan, but Lee is easily my favorite character of the series next to Nina and Lili.
