Battle against Darth Vader/Sideous' defeat

Here's how the battle aganist Vader goes in Return of Darth Sideous. And so is Sideous death.

[the 2 then fly into a big room, then hop off their dragons and slowly search around then they split up]

Darth Vader: [breathing] Come out, Princess Yuna.

[she does and they both clash their sabers as Sideous cackles]

Darth Sideous: Good, use your aggressive feelings, young alicorn. Let the hate flow through you.

Darth Vader: You were taught well, young Yuna.

Yuna: I will not fight you, Vader. You were once a Jedi.

Darth Vader: [approaches her] You are unwise to lower your defenses!

[they clash their sabers at different angles then Yuna jumps onto a high walkway]

Yuna: Your thoughts betray you, Vader. I feel the good in you. A conflict.

Darth Vader: There is no conflict.

Yuna: You couldn't kill me before, and I don't believe you will again.

Darth Vader: You under estimate the power of the darkside. If you
 will not fight, then you will meet your destiny. [throws his lightsaber
 which cuts the walkway down and Yuna rolls off and into a dark corner]

Darth Sideous: good, good.

[Vader searches around for Yuna but she is hiding]

Darth Vader: You can not hide forever, Yuna.

Yuna: I will not fight you.

Darth Vader: Give yourself to the darkside. It is the only way you can save your friends and dragons.

Yuna: [lightly gasps]

Darth Vader: Yes, your thoughts betray you. Your feelings for them are strong, especially for sisters.

Yuna: [gasp]

Darth Vader: So, you have blind sister. Your feelings have now
betrayed her. Princess Luna was wise to hide her from me, not her
failure as Princess is complete. If you will not turn to the darkside,
perhaps she will.

Yuna: [activates her lightsaber and the Lunar Saber] **NOOOOOOOOOOOO!!!!!!!!!!!!!!**

[they clash their sabers in different angles]

{but Yuna is gaining the upper hand and soon leads Vader to a
walkway and swings both of her sabers at breakneck speeds and then cuts
off Vader's right hand with the Lunar Saber!]

Darth Vader:**AAAH!**

Darth Sideious: [laughing] Good, good. Your hate has made you
powerful. Now forefill your destiny and take Vader's place at my side.

[But Yuna isn't listening, as she is distracted with Vader's hand, finding it to actually be a robotic one.]

Yuna: [thinks for a moment and then deactivates both of her
sabers] Never. I'll never join the Darkside. You failed, Sideous, for I
am a Jedi. Like my mother before me.

Darth Sideous: Very well, Jedi Alicorn. If you will not turn you will die. [deploys both of his sabers and activates them]

Yuna; [reactivates both of her sabers] Wrong!

[they both start clashing their sabers at different angles]

[then Luke Skywaker races into the scene as everyone else (save for Blythe and the pets) do the same]

Darth Sideous: [force pushes Yuna back then slams her on the
floor several times] Foolish alicorn, now you will be destroyed. [force
lightning shocks her]

Yuna: **AAAAAHH!!!!**

Darth Sideous: [stops and walks closer] Only now, at the end do
you understand. [continues shocking her as he gets closer and then
stops]

Yuna: [groaning]

Darth Sideous: Your skills are no much for the darkside, you will
 pay the price for your lack of visual. [continues shocking her]

Yuna: **AAAAAHHH!!!!**

Luke Skywalker: Father, please! Don't let him do this!

Yuna: **AAAAHAH!!!!**

Darth Sideous: [stops] Now young alicorn, you will die. [starts shocking her with even more powerful force lightning]

Yuna: **AAAAAAAAAAAAAAHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!**

Luke Skywalker: Father!

[Darth Vader looks at Yuna then to Sideous and then lifts him up]

[Vader then carries Sideous to the big drop just under the walkway and then throws him down it]

Darth Sideous; **YAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHH!!!!!!!**

Darth Vader: [breathing weakily]

Yuna: [gets up]

{Luke then rushes over and holds his father]

Hiccup: Come on, let's get out of here.

[every heads to a ship that has landed (the pets are now carrying Blythe onboard) as Luke carries his father]

Darth Vader: Luke, help me take this mask off.

Yuna: But you'll die.

Darth Vader: Nothing can stop that now, just for once, let look on you all with my *own* eyes.

[Luke and Yuna then help get the mask off and it shows the true face of Anakin Skywalker]

Vikings: [gasp]

Astrid: Anakin?! *You're* Darth Vader?!

Anakin: Yes, I am. But not anymore.

Princess Celestia: Good, old friend.

Anakin: Princess, I'm sorry for my actions back then.

Princess Celestia: All is forgiven.

Anakin: Now go. [Leave me.

Luke: I will not leave you father, you're coming with us, I've got to save you.

Anakin: You already have. You were right, you were right about me. Tell your sister, you were right. [slowly dies]

Luke: Father, I won't leave you.

[But Vader dies]

Yuna: He's gone.

Luke: [mourns]

Princess Luna: Let's go.

[they all board the ship and it takes off]
