Let's open this up to adultish (-ish people the board is rated G) cartoons and superheroes since we can bash them.

My list

1) Princess Aika from the Tenchi series is too, um, haughty

2) Mihoshi from the Tenchi series is too much of a dumb blond joke.

3) Jessica Rabbit is married. (I don't poach even fantasy.) Ditto Betty Rubble.

4) Many other cuties are just too young, like KP.

5) Rogue from the X-men you could never touch.

6) Wonder Woman -- even if the lasso has possibilities she would not explore them.

7) Pocahantas (sp?) because any woman who picks up a bear cub and gives it to the Momma bear will not be long for this world and I'd rather not get attached, thank you.

8) Bulma on Dragon Ball and Dragon Ball Z because she won't shut up and will blame me for every little thing. (Vegetta must really love her if he won't kill her.)

Snow White is too vain for my taste.

Wendy (from the Superheroes cartoons that hangs around with Marvin & Wonderdog) ANYONE who hangs around with those two losers isn't worth much.

Judy Jetson is too spacy. (no pun intended)

Janya (The Wonder Twin) Her animal transformation act is annoying.

I've got agree with John on Snow White. Although I didn't think specifically of them I assume Judy Jetson, Wendy, and Janya are too young. (Although Janya is apparently alien and age might be different she appears to be a "teen side kick" and I just could never get past that to rejecting her on more solid grounds.)

I always pegged Marvin and Wendy at around 19 or so...

Batgirl. From the animated series. She's pretty. She's in college so she is old enough. She could kick my butt, but we could get around that. She would explore kinky stuff. Trying to get her over her crush on Batman, however, is too much work. Besides she might uncover my evil plot to dominate all of Gotham City!

Cat woman, however, I'd date. Any kinky stuff would not be because she was a goody-goody trying something to please me, and her crush on Batman is history by season #4.

Harley Quinn, Poison Ivy, Roxie Rocket, et al. no because they'd kill me.

The more cartoons I see the longer my list grows. Ever major heroine has a really big personality flaw. I already forgot her name, but the female character in Sinbad might be good for one coffee, but I would not waste my money on a second date.

Tea from Yu-Gi-Oh.

Clearly the artists had never met a 14 year old.

Has anyone watched "Drawn Together", the animated reality show on Comedy Central. The whole point of the show is to make the cartoon characters as offensive as possible. Tute Brownstein is a overly horny Betty Boop type. Foxy Jones is a 70's Hanna-Barbera jive talking African American woman. Another character is a flamboyant queen who keeps insisting he has a "girlfriend". Spanky Ham...well, his name says everything. Etc. The show is so intentionally distasteful, that it really loses its sting quickly.

The only bit I found funny was the last episode. In it, a Donald Trump character literally gets off telling people "You're fired". Yes, power is an aphrodisiac!

Rona, it's a parody of "The Surreal Life". (The WB), where in a bunch of has-been stars live together in a house for a period of time. The first season included such notables as Tammy Faye Bakker and Ron Jeremy.

Scott, that was the second season of The Surreal Life. BTW I've only seen 2 episodes of Drawn Together but I liked it's Family Guy style of "throw everything at the wall and see what sticks, comedy."

Years ago, I had a crush on Catsy from Sailor Moon.

Ah, the joys of Justice Leauge Unlimited. Black Carnary, Vixen, Powergirl, Fire, Shayera Hol, Zantanna, Big Barda, Supergirl... The list goes on.
