Best Opposites Attract Couples in Romance Novels?

One of the best pairings of opposites is the strait-laced Jane with the bald, tatted up guy in Victoria Dahl's Talk Me Down. Totally believable, and they each stayed true to their characters as they fell in love.

I can only think of TV examples! Fail. But the one that sprang immediately to mind was Mulder/Scully--the believer and the skeptic. I love the balance they bring to each other and the story, especially in the earlier seasons.

Derek Craven and Sara Fielding from Dreaming of You...

The first favorite that comes to mind is the ultra shy, stuttering Wallflower Evangeline "Evie" Jenner and the uber libertine rake Viscount, Sebastian, Lord St. Vincent. I loved Lisa Kleypas' Wallflowers series!

How about Rupert and Daphne in Loretta Chase's "Mr Impossible"?

I love the couple from Kleypas' "Smooth Talking Stranger". He's a good ol' boy from Houston and she's a liberal advise columnist from Austing, what could be more opposite or better?

On the surface, Eve Dallas and Roarke (J. D. Robb's In Death series) seem to be polar opposites. She's a law and order girl and he skirts the edge of it, at least until he met Eve. Roarke's finesse and shine and Eve is totally in your face. He's absolutely gorgeous and she could care less about makeup, hair and wardrobe. But, these two work!

I thought I don't like this trope, but reading the comments makes me change my mind. Some of my favorites are here.
Let's see... opposites: how about most of the Psy Changeling series by Nalini Singh?

Valerius and Tabitha from Sherrilyn Kenyon's Seize the Night are one of my all time favourite couples. So few of the Dark Hunter books have an awesome heroine AND hero in one book - the emphasis is usually on the hero, but Tabitha made for such a wonderful lead. I love how frequently they reach compromises without having personality transplants by the end of the novel.

Lisa Kleypas sugar daddy!!!
