Creepy or sexual characters who still have some morals

Austin Powers rejects Vanessa because she's drunk

Ice King leaves as soon as he finds out Princess Bubble Gum is 13 ( despite her actually being older, he doesn't pull the whole "she only looks young but is actually a 1,000 year old blah blah)

Archer rejects Anka because she's 14 (does ask her to call him when she's 18 though)
