Choda-boy and his magnificent cock-rocket from Orgazmo
Sorry, Vorae, but if you watch the movies closely, Wedge’s true greatness stands revealed - he’s not a Jedi, he doesn’t get the princess, he’s just a guy who does his job exceptionally well and always manages to come home, even when the Rebels take 98% casualties. And he saves the whiny farmboy a lot. And he’s the first to take out an Imperial Walker. And he survives both Death Star battles. I knew he was a badass when I was a little kid - my “Luke Skywalker, X-Wing Pilot” action figure was never Luke to me. He was Wedge.
Wedge is great and all, but whose side is he kicking? I never think of him as a sidekick because he’s got his own agenda going on – he doesn’t tag along after Luke or anyone else.
Now Chewie, on the other hand, is an excellent sidekick.
I dunno… he’s a great mechanic and all, but I’d like to see him try fixing the falcon from the outside during a battle! R2 all the way, man… 
Don’t tell him I said so, though. I like my arms in their sockets.
The actor who played Wedge, Denis Lawson, is the uncle of Ewan McGregor, and it was his example that inspired young Ewan to become an actor.
That said, Wedge was not a sidekick. He was barely more than an extra, frankly, and he deserves no place in this thread.
I’ve just remembered another serious omission: Jerome! Morris Day’s sidekick in The Time.
Of course he’s not fictional…unless he was also the sidekick of Morris Day’s character in Purple Rain (I didn’t see it).
See, I always thought Jay was Silent Bob’s sidekick, not the other way 'round.
another vote for Gabrielle from Xena
any Companion from Mercedes Lackey’s books

Lately, I’ve become partial to Edgar Tolliver from David Feintuch’s Seafot Saga novels.
I’ve always been partial to F’nor, too–he’s not as one-dimensional. Though to give F’lar his due, bearing the future of the planet on one’s shoulders would tend to narrow one’s focus.
But my favorite is a bit more obscure: Sean O Lochlainn. Master Sorcerer, Chief Forensic Sorcerer to His Royal Highness Richard, Duke of Normandy, and Lord Darcy’s right-hand man.
Who could forget Pinky from Pinky and the Brain?
And the Cyber Side-kick of Joe Cartoon, Suepahfly – “Who’s Yor Daddy?”
Theres still a dearth of female sidekicks in this thread. To redress the balance, Im going to nominate Leela, the uber-assistant of the best Doctor Who, Tom Baker. Wild! Untamed! Savage! Scantily clad! {Her rawhide minidress did much to colour my adolescent fantasies for years to come} Out of all the Doctors legions of female assistants, she was the toughest and the least helpless: the alien threat didnt exist that couldn`t be faced down with a stone knife or a poison dart. Admittedly she could never stay where she was told to, {“Stay here, Leela.” “Yes, Doctor.” Pauses, then wanders off in opposite direction. Is promptly captured.} but that was more a failing sui generis.
Oh, I forgot Minute Mouse!!!
Without a doubt, Captain Call’s sidekick Gus McRae.
Miss Moneypenny.
Especially in the last few movies, Moneypenny has definetely been more of a sidekick.
Oh… and since we’re talking Bond here… his penis.
Ace could kick Leela’s ass. She used guns and explosives. Although her clothes were far less revealing.
I’ve got to go with Beeblebrox here. Sancho Panza is one of the best sidekicks of all time. Patroclos is also a great sidekice. Both of these sidekicks are arguable better characters than their protagonists, Don Quixote and Achilles respectively.
I’ve got to go with Kano from the Green Hornet.
Hey Tranq, I’ve got to go with Preview from the SMBD! Sorry, I cannot help myself!
Gonna have to call you on this one, Hastur. Miss Moneypenny kicks no sides. No sidekick she. Staying in the MI5 office pining for the day Bond gives her one is not in keeping with the true spirit of sidekicking - she`s never even needed rescuing: besides, like the man says, “I work better alone”.
Hands down, it’s Gir from Invader Zim.
Waaaah! I loveded you Piggy! I loveded yoooooou!
