Que Passa!!!!
Well, I don't play as Lori as much as most(I'm a total Spaz fan, you know.) but I DO like her, so I'll post my reason:
1) Purple is a cool color, and Lori wears Purple.(I won't say anything about yellow...)
2) I came up with a pretty likable personality for her in both my fanart, and in my War tavern stories(Lori seems to have a different personality for everyone... Unlike Jazz who is always a bit of a hotshot, or Spaz who is always... Spaz, just with random differences in how intelligent he is. I made her kind of a hotshot smarty type.)
3) Her death scene in the game is just slightly below Spaz's in terms of how funny it is. (Jazz's is far too bland.)
As for the sexy thing, well, I'm not really into that kind of thing with videogame characters. /\
/\ I would probably choose Ms. Pacman over Lara Croft, to give you an idea.
