Han and Leia
Ahhh, the classic couple of Star Wars. We watched Han win Leia's heart throughout the original trilogy and into the Expanded Universe. The most attractive thing to their relationship is the difference of Han and Leia's personalities. Han, being the cocky scoundrel, seemed different than Leia's spunky princess personality but they clicked perfectly. Both seem to relate to each other with their charm and relative strong persona. While Leia is still a petite woman, she's not afraid to stand her ground, which may have brought attention to Han. Personally, I love watching them make witty comments towards each other. The all famous "I love you/I know" scene in The Empire Strikes Back is the most romantic thing in existence. I swear, if a man ever said that to me, I'd probably faint and die from epicness. It's really neat that Han and Leia exchanged roles but said the same words in Return of the Jedi too. They're also quite sweet in the Expanded Universe while caring for their children and such. Han always knows how to calm Leia if she's stressed or worried about something.
Rex and Ahsoka
As stated above, this is an extremely debatable topic in the world of fangirls. Before you get all irate and crazy, just keep reading and try to be respectful of our opinions. Rex and Ahsoka seem like they'd be the perfect couple because they relate in so many aspects. First of all, they've experience war together which is a big deal. If they ever needed to discuss the trials and tribulations of this tough time, they could support each other. Secondly, since Rex is a clone warrior, he's around other Jedi often and understands their way of thinking. This could benefit their relationship by knowing boundaries of emotions and values. Many people hate this pairing because they think that Ahsoka doesn't need a man. This is a very valid point because she is a strong female but, we like this pairing for the sake of fantasy. There is a possibility of Ahsoka falling in love with the Separatist kid Lux but, we like to imagine her with the loveable Rex.
Luke and Mara
Oohhh...Luke and Mara! Luke and Mara are the couple of the Star Wars Expanded Universe. They meet in the famed Thrawn Trilogy by Timothy Zahn, and instantly Mara Jade hates/despises/wants-to-kill Luke. Even after their rocky start, Luke and Mara become allies by the end of the trilogy, and later even friends. Mara joins Luke at his Jedi Praxeum on Yavin IV to be trained in the ways of the Force, but leaves prematurely due to both of them having control issues. After ten years of having an on-again-off-again friendship...the Force pretty much takes Luke's and Mara's relationship into it's own hands...(does the Force have hands? I don't know if that sentence made any sense...but bear with me here.). While in some seemingly Force-foresaken cavern during the book Visions of the Future by Timothy Zahn, Mara and Luke have an awesome Force-Melding of their souls. *major squee* He proposes on the verge of death, and she says yes. Everything is perfect and amazing for a while....and then the whole galaxy falls apart again, and more stuff happens that totally ruins everything, and ultimately she dies, leaving Luke and their fairly young son, Ben, all alone. :D
Anakin and Padme
As Han and Leia are the featured couple of the Original Star Wars films, Anakin and Padme are the superstars of the Prequel Trilogy. The two first meet when Anakin is still a little boy of nine....fresh off the....er....slaver's block (*winces at how cruel that sounds, even though it's pretty true*) on Tatooine. Padme was a young queen, and the two automatically become friends, young Ani smitten with the pretty girl. Their romance really picks up about ten years later, when Anakin is a nearly-20 year old Padawan under his Jedi Master Obi-Wan Kenobi, and Padme is the Senatorial Representative of Naboo. Anakin's first solo mission is to protect Padme from the people who want her dead. They then end up fighting for their lives, and confess their love to one another, discovering it impossible to hide their true feelings (Anakin especially, finds this difficult). They are married shortly after the Battle of Geonosis, before the start of The Clone Wars. Anakin and Padme keep their marriage a secret for many years, until the end of the Clone Wars, when literally the galaxy falls apart. By then, Padme's pregnant with Anakin's child (hehe...children, is more like it) and Anakin is dealing with serious fear issues. Ultimately, he kills all the jedi and a bunch of little kids, and becomes Darth Vader to try and save Padme's life. She dies of a broken heart. (way to go Anakin) But she still gives birth to the baby (babies), who then live their lives in secrecy thanks to Obi-Wan Kenobi. (Yay for Obi-Wan!). So this concludes the tragic, but beautiful, romance of Anakin Skywalker and Padme Amidala.
