Star Wars Infinities is a series of comics, which I personally don't like, that deal with "what-ifs" in the Star Wars Universe. The storyline is altered here and there and the whole deal comes off a lot different than the actual storyline. As a fan(atic) I consider this blasphemy. Why I mention this is because I was just watching in-sequence the original trilogy, and I started thinking... what if...
Let your imagination go wild as we consider these infinities.
Variation 1: Father and Son vs Sister
Ignoring Yoda and Ben's warnings, Luke Skywalker makes his way to Bespin. He encounters a trap laid by Darth Vader. They fight. Vader chops off his hand, and tells him the "truth". Confused and in pain, Luke can think of only one thing - he has found his father. He forgets that this was the same man who killed Uncle Owen and Aunt Beru, tortured Han and Leia, and tried to shoot him to death on the Trench Run. Overwelhmed with mixed emotions where Yoda and Obi-Wan's betrayal only shines, Luke loses consciousness and falls into the gas tunnel. Using the Force, Vader grabs him out of the air and lands him safely next to him.
As Leia, Chewbacca, and Lando begin their search for Han, thinking Luke lost to death by Vader's hands, Luke arrives on Imperial Center (formerly Coruscant). Under the Imperial med-droids care he recieves a black armored gauntlet that replaces his right fist - reminiscent of Anakin's first prosthesis. And under the cruel but powerful tutelage of his Father and the Emperor, Luke is drawn completely to the Dark Side. Having lost Anakin Skywalker's lightsaber at Bespin during his fall, he builds a new - RED - lightsaber. Vader tells him his training is complete.
Without Luke's help Leia, Chewie and Lando rescue Han Solo from Jabba the Hut. After escaping Tatooine in the Millenium Falcon, Leia has a dream in which Obi-Wan comes to her. Tells her of her heritage. And beckons her to follow the path of the Force - the path of a Jedi. Leaving Han and the others, Leia leaves for the Dagobah system. There she goes through Yoda's last training, and forges her own GREEN lightsaber.
Meanwhile Luke escorts the Emperor to the new Death Star where Vader awaits. The Emperor reveals his plan for the Rebel Strike that is imminent. Luke is sent to Endor.
Leia and Han lead the strike team on the assault on the shield generator on the forest moon of Endor. While staying the night at the Ewok village, Leia confronts Han and tells him the truth about her, her family, and where she went (Dagobah). She tells him that Luke is still alive, but a servant of the Dark Side. She tells him there is still a chance he can be saved and she must take it. She leaves Han and turns herself over to the local Imperial garrison.
Leia finds Luke at the garrison. She tries to talk to him about leaving Vader's side, but he tells her - almost sadly - that it is too late for him. He looks at her lightsaber, activates it, and congratulates her on completing her training. She tells him of Yoda's death. Luke scoffs at the news, telling her that all Jedi do is decieve and betray.
Luke takes Leia to the Emperor. Entering the Throne Room, they see Vader standing over a large crater in the floor where a tattering black robe lays. Vader turns off his lightsaber and turns to see his children. Leia tells him that she has come to take her brother back. Vader tells her he will not go, that he has complete control over him. Leia, only half-trained by a dying Yoda, gives in to her anger, calls her saber to her hand through the Force, and lunges to strike Vader with her lightsaber only to be intercepted by Luke's lightsaber.
Brother and sister fight.
Leia's powerful strokes batter Luke to the ground where she chops of his whole right forearm! Howling in rage, Luke slumps to the floor. Vader laudes Leia's abilities and commands her to strike down her brother and take his place by his side. That it is her destiny. Leia calms down and finds her center. She looks at her brother. The brother she came to save and yet almost ended up killing. She throws away her lightsaber and claims that she is a Jedi, like her brother before her. Vader releases his fury at Leia in the form of Force Lightning. Bolts of lightning wrap Leia and seep her strength. Curling into a ball on the floor, Leia calls to Luke for help.
Sub-Variation 1a
Watching his sister in agony, Luke comes to a decision. His mind is clear. He grabs Vader from behind and thrusts his lightsaber into his chest. The Dark Lord of the Sith falls to the ground and dies in a burst of Dark Side Energy.
But in helping Leia and protecting her from the Dark Side Burst of Energy, Luke himself is crippled. He tells Leia that she has finished what she set out to do. That she has saved him. Luke lets go of the living world and fades into the Force. Leia escapes the Death Star as it explodes.
Sub-Variation 1b
Watching his sister in agony, Luke comes to a decision. His mind is clear. He grabs Vader from behind and thrusts his lightsaber into his chest. The Dark Lord of the Sith falls to the ground and dies in a burst of Dark Side Energy.
Leia helps Luke - who is now crippled from the explosion - up. They both know they have struck the death blow to the Empire. But they also know its too late for them. They embrace each other as the exploding Death Star consumes the Last of the Jedi.
Sub-Variation 1c
Watching his sister enveloped in bolts of electricity, Luke Force pushes Vader out of the way and stops his barrage of lightning. He tells him "She's mine" and drives his lightsaber straight through Leia's body.
Vader regains his balance and walks towards Luke and says "Well done, my son. You are truly strong." only to hear his son say "And you are too weak". Luke activates his Lightsaber and lunges at the former Dark Lord.
Sub-Variation 1d
Watching his sister enveloped in bolts of electricity, Luke grabs Vader with the Force and hurls him down the reactor chute. Vader dies in a fury of Dark Side energy. Luke walks up to Leia who is struggling to get up. He squats down to her. He touches her cheek gently and smiles at her. Leia sees hope. But the smile suddenly turns deadly as Luke says "Goodbye, dear sister" and runs her through.
Luke Skywalker, the Last of the Sith, assumes command of the Empire. He wipes out the Rebellion at Endor and plans to take the Empire to heights even Palpatine couldn't.
Now this all seems blasphemy to me and I am considering myself a blasphemer. But you gotta admit - this is interesting.
