Talking about Anakin's, I offer this What If scenario.

What if Anakin-who-was-Vader survived after throwing the Emperor down the elevator shaft?

Scene: The Death Star is in shambles. Troops and officers run everywhere as the station begins to destroy itself. Amid the chaos, Luke Skywalker is dragging the lifeless form of Darth Vader toward an escape shuttle.

The Cargo Supervisor stops Luke in mid-stride. "Hey buddy, whatcha got going on here?"
"Just trying to get out of here. This whole station is about to blow!"
The Cargo Supervisor scratches his head beneath his cap. "Ain't that a... Ain't that uh... Lord Voldemort or whatcherthingy?
Luke is impatient and begins to drag Vader again. "I really don't have time for --"
The Cargo Supervisor yells over to his foreman. "Tom! Come here and check this out."
Tom comes over and whistles in appreciation. "Do you need a hand with this guy?"
Luke pauses for a moment. "I guess so... sure. Thanks."
The two men in dungarees stoop to pick up Vader's legs.
Cargo huffs and puffs. "Blaster me! This guy's heavy."
Tom pulls and twists too much, and Vader's right leg prosthetic pops off in his hands. "Oopsie. Boy, that's gotta be embarassing. Good thing he's out cold."
Vader moans.
Luke sees five officers making their way across the hanger toward the escape pods. One of them stops his comrades and points their way. The group huddles and breaks with a hand-pile salute and a menacing cheer of "Huhzah!"
As they break into a raucus sprint toward Vader, Like sighs. "Oh, brother." They begin yelling and kicking, shoving the crewmen aside.
"Not so tough now, are you, big guy?" they taunt. Nearby Stormtroopers begin throwing things like popcorn and tomatoes, some of which hit Luke about the face and neck.
"Boy, they really hate you here, Dad!"

Finally at the ramp of the shuttle, Vader finds his voice. "Luke, help me take... this mask off."
Luke is concerned. "But, you'll die."
Vader ponders this for a moment. Finally, he just says, "Oh.."
Luke ignores him and drags him aboard to escape the exploding station.

Safely landed on the forest moon, Luke helps Vader to sit up. Vader says, "I'm feeling much better now. I think I could go for a walk. Thanks for not taking off my mask back there -- I was a little out of it."
Luke sprays some Windex onto a rag and polishes his father clean to the best of his ability. "Let's get you a little shined up before we go meet everyone, okay?"

Above in the Ewok tree village, a loud celebration just keeps getting louder. One group of platforms is intent on singing the Yub Nub song while the neighboring party is playing some new-age yah yah piece.

Han, Leia, Chewie, and the droids greet Lando, Wedge, and the rest of the Rebels as they return from victory. Everyone is dancing, though it looks like Lando doesn't have much rhythm. An ewok gasps, and all of the music stops cold. Everyone turns and freezes. Luke comes walking across a ramp with Vader towering behind him. Despite the unbelieving stares, Luke smiles. He puts his hands up toward the crowd. "It's cool; he's with me."
Vader raises his hand to wave, remembers he doesn't have one, and waves with his left hand. "Allo."


The music begrudingly resumes, and most return to their revelry.

Luke is beaming as he and Vader approach Han and Leia. Chewbacca snarls terribly. Luke smiles again. "Easy, Chewie. Dad, I believe you know my friends. And may I formally introduce your daughter."

Vader shifts nervously from foot to foot and attempts a little bow.

Leia steps up and shoves a finger into his chest (dangerously close to his control panel). "You abandoned me and then you tortured me, jerkface. Twice!" She storms off, not before shooting Luke an angry glare.

"Maybe this was a bad idea." Vader mutters.

Han steps up in her place. "The next time you torture someone, ask some questions, you moron," he says as he walks past and shoulder-chucks the former Dark Lord. He stops a few paces away and turns to add, "And honestly, who carbon freezes someone? That really hurt!" and leaves.

Artoo rolls up with some drinks for Luke and his dad. Luke takes them and hands one to Vader. "Okay, so it may take some time. At least Artoo is being nice." The droid's hologram emitter sparkles to life, and Luke winces. It's a looped video of Artoo's head being hit by Vader's TIE fighter lasers. *Blam! -- Wowwwww!* *ckzt* *Blam! -- Wowwwww!* *ckzt* *Blam! -- Wowwwww!* *ckzt* etc. Vader begins to apologise, but Artoo is already wheeling away to zap ewoks.

Vader spies Threepio dancing with an ewok. "Is that... Is that protocol droid named C-3PO?"
Luke nods. "Yep. I've owned him for a few years."
"I made him! When I was a boy, I made him from scratch. Why is he dancing like like that? I never programmed him to be such a wimp."
"He's had his memory wiped a few times. It tends to make him loopy."

Out of nowhere, Vader asks, "So, how did you like my entrance at Bespin?"
Luke chokes on his drink. "Oh, that was great, Dad! I nearly soiled myself."
Vader chuckles -- for the first time in more than twenty years, he chuckles -- and it sounds strange coming from his voicebox. He recites, "'The Force is with you, young Skywalker, but you are not a Jedi yet.' I worked on that line for two weeks before I was happy with it."

Out of the corner of his eye, Luke notices a shimmering blue light. He tugs on Vader's leather to get his attention. There along the ramp appear Obi-Wan and Yoda. Yoda rolls his eyes. Next to Obi-Wan appears Padme. Vader stammers, but she disappears before he can say anything (too many fans complained about the addition). Qui-Gon Jinn appears briefly, too, but disappears just as quickly.

Admiting that this whole redemption thing isn't what it's cracked up to be, Vader tinks glasses with Luke. Embarrased, Luke stops a passing ewok. "Do you have any straws, Chief Chirpa?"
