Heh. She's a fun character, all right, and very popular. One of the few characters to be so popular she was actually introduced first as an animated/cartoon character and then brought into the comics verse because of that popularity.
As for the hotness factor, I prefer her classic costume. I am... not a fan of the game version. Also, I was kinda hoping for more Harley/Ivy flirting. (Snickers)
Hey, there was so much of it in the cartoons and the comics, it wasn't even "subtext," anymore, it was just damn text.

Yeah, the ep Harley & Ivy from the animated series made me wonder a bit. Wonder and visualise
To quote Jayne Cobb "....... I'll be in my bunk"

hey.... when replaying the game will you replay with all the gadgets you got through first replay...
because i missed some stuff cause i don't have explosives... and that saddens me. i don't like missing on stuff.
really? i never noticed. are you sure you didn't look too much into the comics and cartoon? for example: where is subtext on this page?

(Snicker.)
That's why I included "the comics." If I remember right, Bruce Timm and Paul Dini pretty much always wanted Pam and Harley to be a canon couple. They'd be just as dysfunctional as Harley and the Joker ever were. But since they couldn't get away with it in the cartoons, the best they could do was drop lots and lots of hints.
The comics, however, were a far different story. Those got pretty blatant since they had a lot more leeway, and when Harley got her own book (With art by the Dodsons, no less!) well... yeah. Heh!
So for all "official" purposes, the slashers are actually -right- this time. Go, us. :D
