Sonic lies lifelessly in the center with the seven Chaos Emeralds surrounding him. Shadow, Y/N, Tails, Knuckles, Amy, Silver, Rouge, Omega and Eggman stand on the sidelines while Elise prays to the Chaos Emeralds.

"Oh Chaos Emeralds, gems of miracles. Please heed my call."

Chaos Emeralds start glowing brighter.

"I wish to save this world. I wish to cleanse my father's sin. And, I wish to talk to Sonic... once again!"

The Chaos Emeralds and still lifeless Sonic start levitating into the air. Y/N walks over to Elise as her crystal glows brighter too.

"You and your sister have given me so many things. Now it is my time to return the favor. I care not what happens to me. But please heed my voice. Sonic, come back! To me... Your sister... To us!"

Elise nods at Y/N who nods back. Y/N places her hand on Sonic's chest as her hand starts glowing as Elise places her hand against Y/N's. They both closed their eyes as they mumble their prayer together. A bright light whites out the area. When the light dies down, Sonic stands before everyone, revived as Super Sonic. Y/N tears up in joy. Elise falls into Y/N's arms from exhaustion.

"Thank you, Elise." Sonic said.

Everyone is happy at Sonic's return. Y/N brought Elise back up and looks at Super Sonic. Super Sonic turns to Shadow and Silver transform them into Super Shadow and Super Silver. He then turns to his sister to transform her into Super Y/N as well. Super Y/N then created something with the combined power from Sonic, Shadow, and Silver. She transformed all of her weapons and powers into a lava sword.

Sonic, Shadow, Silver, and everyone else are shocked. Y/N gave them a smirk, swinging her sword. The four of super transformed hedgehogs then fly up to combat Solaris.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Solaris roars at them.

"That body of light is the sign of super dimensional life form. Standard attacks won't work on him! He eats dimensions for lunch!" Eggman explained with a warning. "But... There should be something that's anchoring him in this dimension. That's probably the light shells that can be seen on his body. If all of thosr are destroyed, he can be defeated!"

Sonic and Y/N dodged the incoming attack from Solaris before zooming in towards the light shell that Eggman informed them about. Sonic and Y/N smashes and slices into the light, causing it to roar in pain. The lava sword Y/N has in her hand left a bad burning cut on Solaris.

"It's all you, Shadow!" Sonic said.

"Go, Shadow!" Y/N encouraged him.

Shadow takes over as he flies arouns Solaris and brings out Chaos Spears. Solaris tried to block it with his left arm, but Shadow threw more Chaos Spears again, hitting its weak point.

"Silver. It's your turn."

Silver flies up to Silver.

"I'll take it from this. This is the end! Prepare to meet your doom!"

Silver floats the giant dark rocks and threw them at Solaris. He throws more giant rocks at him as Solaris couldn't cover hinself. Solaris been hit in the chest a couple of times as he's slowly weakening.

"Good luck, Shadow!"

"Understood." Shadow nodded. "A super-dimensional being... Heh. This might even be a fair fight!"

Shadow glows red and brings out hundreds of Chaos Spears, hitting his weak point again and again with lots of more spears. He even managed to break the shield from Solaris' left arm as he did the same to the right arm. Shadow called Silver again as he threw more giant rocks. After weakening, the trio called Y/N for the final blow

"It's all yours, sis!"

"Take him out, Y/N!"

"Protect the future, Y/N!"

Y/N zooms in towards Solaris, slicing off the incoming dark attacks and with a mighty war cry, she stabbed Solaris in the chest. The lava sword starts spreading out lines of lava as Solaris started to let out a last pained roar. Y/N withdraws her sword.

"This is for what you did to Sonic!!"

Solaris's body began to break from the lava that kept spreading. Then, Solaris' light orb is giving off bursts of light and everyone is celebrating their victory. Sonic, Y/N, Shadow, and Silver in their super form landed back to the group as they watch on. As a bright light envelops everything, a white flame is formed in a black void.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Sonic, Y/N, and Elise are floating in a black void.

"Did you two destroy it?" Elise asked.

A white light appears.

"...No." Sonic shook his head.

"That is the true Solaris." Y/N said.l, looking at the light.

Sonic, Y/N, and Elise move into the light.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It begins with a flashback where a young Elise and the Duke of Soleanna watching Solaris' original form, a small white flame, in its casing.

"Look, Elise. This is Solaris, the flame of hope."

"It's so beautiful..."

Duke smiles at his daughter.

"When the flame has grown large enough, our world will change. Solaris will allow us to control time and move through history. People will be able to rectify past mistakes and avoid bitter fate."

Young Elise looks at her father in hope.

"Will we be able to see momma?"

The Duke pats her head softly.

"Yes, Elise. We'll both be able to see your mother once again."

The Duke and the young Elise leave Solaria, it then turns to present where the present Elise, Y/N, and Sonic are approaching Solaris' casing.

"This is where everything began. Who knew such a tiny flame could bring such devastation?"

Elise takes out Solaris and its candleholder.

"If we put out this flame, Solaris will never exist, And then we'll never have to worry about the Flames of Disaster, right?"

Sonic and Y/N nods.

"But our encounter... You and I will never meet. It will never have happened. I... To tell the truth, I don't care what happens to the world!"

Elise begins to cry. Y/N walks up to Elise and hugs her, trying not to cry.

"It's okay, Elise."

Elise looks down at Y/N.

"Just smile."

Elise then looks at Sonic who nodded with a smile. She hugs Y/N back with one last look at the hedgehog siblings, smiling at them. Elise softly blows out Solaris, and everything fades to black.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

That night in Castle Town, the Festival of the Sun is unfolding and Elise is in her boat waving to the audience. As Sonic and Y/N comes running and roller skating, they notice Elise and run and skate by so fast that they created a wind with sparkles from Y/N's crystal that makes Elise lose one of the feathers in her hair. Elise stands in awe after feeling the wind and seeing sparkles that look like the shape of the crystals as they fall on her face.

"Miss Elise?" Lady-In-Waiting asked.

"It felt like... like someone was calling me." Elise said, looking to where Sonic and Y/N might be gone.

"I'm sure. It's just the wind. Although, the sparkles look beautiful."

"Of course. But it felt so familiar somehow..."

Elise continues the festival while Sonic and Y/N watches it from a rooftop. As Elise's feather flies into the sky to the moon, Sonic and Y/N watches it while smiling fondly. The hedgehog siblings smile at each other before they zoom off together.
