Sabrina is the hottest Gym leader, Erika gets the Honorable mention. Honestly don't see what everyone sees in Jasmine. >.>
I'm going with Sabrina because she showed her navel in HGSS even though Gardenia did the same.
What is it with how the Kanto ones are the hottest?
Lets see here from Gen I i'd have to say Misty, Gen II Clair, Gen III Winona, but I also like Flannery, and then in Gen IV Gardenia is the hottest.
Gen IV, for me, is Maylene.
Clair captured my heart in SoulSilver, no pun intended, with her passion for battling to the point where she couldn't accept her loss. Fantina was pretty hot too.
Clair, hands down. She is WORKIN that cape.
GSC=Clair, Erika (:-p)
DPPt=Gardenia (I would put Candice... but she looks a little young for my taste, even though she is obviously not below 16)
HGSS=ERIKA :-p, Clair, Misty
Always an Erika fan, although saying I ever had a crush on her would not be honest. ^_^
I'm going to have to say Volkner.
When I saw him in Pearl I was speechless. lol
I know this is a shocking statement, but...
Just look at the arrow. Other honorable mentions: Misty, Sabrina, Jasmine and Candice.
