In the world called Wonderland The Queen of Hearts is reading the letter from King Sora.
"Royal Sorceress!" calls The Queen of Hearts. A burst of black and green smoke appears and when it clears Maleficent with a magical disguise on. The Queen of Hearts hands her the letter.
"This letter informs us that a dark being has been visiting this world often and a princess is coming to give us a weapon to defeat it for good," explains The Queen of Hearts as Maleficent reads the letter. "I want you to receive it, find this dark being and put an end to it yourself."
"I shall do as you've commanded," replies Maleficent. "While you deal with the intruding princess?"
"What do you mean?" asks The Queen of Hearts.
"Take another look here," responds Maleficent, handing The Queen of Hearts the letter. "It says that this princess is coming here. Not asking if she could come."
"My goodness you're right," exclaims The Queen of Hearts, then she walks off. "I'll speak to the guards about that." Maleficent watches her leave with a grin on her face.
At The Radiant Garden
King Sora and Queen Kairi are wishing Princess Hi good luck before she takes a gummyship to Wonderland. Princess Hi has replaced her traveling clothes for what looks like formal wear, but can turn into battle worthy clothes with just a magic word.
"Here is the box with the light in it," says King Sora as he hands her a box. "Whenever the box is either opened or destroyed it will release the light inside. The only way for any beings of darkness to survive is to flee the world the light is in. I already have the keybladers in place so that the only path leading from Wonderland is to The Keyblade Graveyard. There is the item you told us to make to help you destroy Maleficent once and for all." He then puts a hand on Princess Hi's shoulder.
"Hi, you've grown up so fast, it seems like only yesterday I was holding you in my arms for the first time," says King Sora. "Now you're a very strong keyblader about to have your first showdown with a being of evil. And along the way you followed your own path, that makes me the most proud." He finishes the last part off with a smile and a hug. Then it is Queen Kairi's turn to wish Princess Hi luck.
"No matter what other people had said in the past we've always been proud of and loved you," says Queen Kairi as she hugs her. "And we always will." With all said and done Princess Hi boards the gummyship. With a wave she closes the door behind her.
Later on in the garden (outside the part the trial was in Kingdom Hearts)
The Queen of Hearts and Maleficent are there with some of the card soldiers in front of the entrance to the court part of the garden. Princess Hi enters through the entrance to the garden. Immediately seeing though Maleficent's disguise she quickly casts a spell without summoning her keyblade. Roxas once taught her how to do magic without the use of a keyblade. Once she's in front of Maleficent and the local worlders she does a curtsy.
"Queen of Hearts of Wonderland, I am Princess Hi, daughter of Sora, King of The Radiant Garden, God of the underworld and incarnate of Kingdom Hearts," begins Princess Hi. "I come bestowing a gift to your world as soon as possible to help protect your world and destroy this evil being."
"I accept the gift," responds The Queen of Hearts. Maleficent steps forward.
"This is my royal sorceress, Benevolent," introduces The Queen of Hearts. "I gave her the job of taking care of the dark being your king warned me about."
"OK, just be careful," says Princess Hi. "If the box breaks the weapon will be destroyed."
"Don't worry, I'll be careful," smiles Maleficent as she walks towards Princess Hi.
"And now that I have the weapon, OFF WITH HER HEAD!" yells The Queen of Hearts. But as Maleficent touches the box black and green smoke surrounds her. When it clears Maleficent is standing there in her true form holding the box.
"You see Queen of Hearts," says Princess Hi. "Your royal sorceress is really the evil being that's been visiting your world."
"True," replies Maleficent before she rises high in the air. "But now I have the weapon you were going to use on me. Once it's destroyed there will be no hope for anyone." She tosses the box in the air and shoots it with a beam of magic. The box bursts into pieces and the light inside is released. Maleficent escapes through a dark portal.
"Don't think you we're not done with this yet," Princess Hi says to Queen of Hearts before following Maleficent through the same portal. Leaving behind a shocked Queen of Hearts.
It took a while, but Maleficent and Princess Hi finally makes it all the way to The Keyblade Graveyard. All that's there are the keyblades of the dead keybladers that fought in the first keyblade war, and a portrait of Maleficent.
"You didn't… need to do… all that… just for me to see…. a portrait that's… for me," pants the now extremely weakened Maleficent, stumbling as she's trying to stand.
"You're right this is a portrait for you, it's for you to get destroyed in," responds Princess Hi. "Reversia, teleportrait." With that spell cast Maleficent is sucked into the portrait, and the image of her comes to life. Princess Hi points her keyblade at the portrait and shoots a beam of light at it. A shining keyhole appears in front of the portrait for a while before fading away, signaling that the portrait is locked.
"What's happening, I can't get out," says Maleficent's portrait image.
"That's because I locked you in there. And now, all's left to do is to destroy the portrait. Thus ending your time in life," explains Princess Hi. "Any last words?"
"Do you really think I am going to be the only Maleficent to be created?" says Maleficent. "I was made from the darkness in Enchanted Dominion. As long as darkness still exists in that world Maleficents will always be created."
"Then history will keep repeating itself for as long as Enchanted Dominion creates new Maleficents," replies Princess Hi walking to stand in front of the portrait, then she raises her keyblade to point at it. "Firaza!" The effect of the spell looks like Princess Hi turned her keyblade into a flamethrower. It turns the entire portrait into ash in a matter of seconds. With Maleficent defeated once and for all Princess Hi activates Goddess Mode and shoots unlocking beams to the worlds she lock. She also sends a message through her heart telling all her friends on those worlds that Maleficent is gone for forever. She then opens a light portal and goes through it.
She walks out in the town square of The Radiant Garden. What she sees surprises her. All of The Radiant Garden's people are there, with all the keybladers in front. King Sora and Queen Kairi are at the head of the group.
(A/N: begin the song Sanctuary – After the Battle (PS. I love that song and think it's perfect for this scene))
"Mother, Father," exclaims Princess Hi as she runs up to King Sora and Queen Kairi. The two parents of the royal family embraces her.
"I'm back," says Princess Hi once they part a little bit, remembering that part of King Sora's bedtime stories.
"You're," says Queen Kairi.
"Home," finishes King Sora. Both smiling at the memory as they part all the way to let Leopan, Igneous and Pupa Ningyo congratulate their friend. Master Aqua had separated and destroyed the fake heart that was in Pupa while Princess Hi was getting ready to put the plan in motion. Now he's his own person. All is well in Princess Hi's life again, for the time being.
