This is a retelling/AU/whatever of the 2006 Sonic the Hedgehog (still better than Sonic 2006, right?), crossed with Disney's Frozen. I was thinking about something a few days ago: "Man, I've never played Sonic 2006, but even I think that *censored*. First of all, Sonic deserves a better princess than Elise. Someone like Elsa". Then I thought about writing a Sonelsa fic and...you get the idea.

There is also some kind of prologue in this chapter, explaining how Sonic, Shadow and Silver are brothers even though they live in different time ranges, and a simillar thing for Anna and Elsa (who are twins in this story). AND why the Master Emerald needs a guardian even though it's located on a flying island which nobody has ever heard of and which can't even be found on the world map in Sonic Unleashed.

Author's notes: Anna and Elsa are 16 in this story (except in the prologue, where they are 1). James the Hedgehog and Senya Rose are IsonicfanI's OCs, not mine. Only Amanda the Hedgehog is mine. And talking about IsonicfanI, this story uses his versions of the Sonic characters (the annoying Shadow, the tomboyish Amy, the idiot Silver etc.)


Prologue

15 years ago, in the city of Arendelle:

The Master Emerald, which was currently being held by the royal family in the centre of the city due to an agreement between Arendelle and the Echidnas, was starting to become unstable. Sure, that had happened before, but it had never been so bad. It looked like it was about to explode. James and Amanda were running for their lives, along with the King.

James: "What's going to happen now?"

The King of Arendelle: "I'm afraid I do not know. Hopefully, the Echidnas will be able to fix this"

Amanda: "Hopefully? And what if they won't?"

The King of Arendelle: "Then we'll have to hope for the best"

The Echidnas gathered around the Master Emerald in a last effort to bring back the Chaos Energy balance. An explosion of light emerged from the Emerald by the time everyone managed to get back inside their houses. However, it faded quickly. But was that light harmless?

Inside James and Amanda's house:

Amanda: "Good thing it's finally over"

James walked into his children's room with the intention to check on them. He first looked in Sonic's crib. He was awake, but he seemed alright.

James (tickling Sonic): "Hey, there, little lad. Did the big bad Emerald scare you?"

Sonic laughed.

James: "That's my kid. We aren't afraid of anything, are we?"

James then went next ti Shadow's crib. But Shadow was missing. "Huh? Where could he be?". He then walked next to Silver crib. Same thing.

Amanda was preparing dinner when James walked in. "Amanda, something's wrong! Shadow and Silver are missing"

Amanda: "Missing? Do you think the Master Emerald had anything to do with it?"

James: "I'm sure"

The next day, the King and the Echidna leader held a city gathering at the castle.

The King: "My dear people, first of all, I have horrible news. Following last night's incident, one of the two princesses of Arendelle has disappeared"

James raised his hand. "Your Majesty, two of my children, Shadow and Silver, have disappeared as well"

The King: "Yes, I was about to explain this. More people have been reported to be missing. Most of them were simply teleported somewhere else, and my guards were able to find them. Unfortunately, there was no sign of your sons or my daughter. I'm sorry"

James: "What? So what you're saying is that-"

The Echidna leader: "That your children, as well as Princess Anna, must have been sent into another time period"

Amanda: "Another time period? And how are we supposed to find them?"

The King: "We will see"

The Echidna leader: "In the meantime, it is clear that the Master Emerald is extremely dangerous and cannot be kept in Arendelle anymore. My people will take it back to the Angel Island immediately"


In the present day:

As time passed, Sonic managed to find Shadow, but still no trace of Silver. As for Elsa, she had heard that she had a sister "lost in time", but just like in Silver's case, there was no trace of her.

Sonic, James and Amanda were attending the Festival of Sun in the city of Arendelle. Shadow said he was "busy with something else" and that he couldn't come. A large boat came down the river, carrying Princess Elsa. The boat came to a dead end, approaching a large structure, on which Elsa stepped as she was handed the ceremonial torch.

Sonic (sarcastically): "Good thing we have the best places"

James: "Hey, it's not that bad"

Amanda: "We're on a rooftop"

James: "Well, at least it's not me who spent 30 minutes in front of the mirror getting ready"

A voice came from inside the building on which they were standing. "Quiet there, some people are trying to sleep! Stupid Hedgehogs!"

Sonic (whispering to Amanda): "Who's that?"

Amanda: "The crazy old lady who keeps us awake all night with her phone calls at 1 o'clock in the morning"

James: "Well, have a taste of your own medicine!"

The crazy old lady: "It's not my fault that you can't be nice and help an old lady!"

James: "Oh, I can't be nice? Well I have some really nice words for you!"

Amanda covered James' mouth with her hand. "Darling, let's keep them for later, preferably for when the princess won't be around"

Elsa closed her eyes for a few seconds. She saw something. She saw fire. A large blast of fire, destorying the whole city, with a beast in the middle.

The lady-in-waiting: "Miss Elsa-"

Elsa opened her eyes. "It's alright" She looked back at the statue in front of her. "We give thanks for the blessed flames. May we always continue to have peace. Sun of Arendelle, guide and watch over us with your eternal light!"

Elsa lit a flame on the statue with the torch and everyone applauded. But that lasted little, as missiles attacked and the people panicked.

James: "This doesn't look good"
