The story begins on its sites in a beautiful small town named greenhouse. Then seeing a Blue blur running around and it was none other than Sonic the hedgehog

Sonic (VO): now before I tell you the craziest moments that happened to me throughout the past years. How about we go back to the beginning. This is green hills. My home, my playground and my responsibility. A lot has changed after past few months for me. Stop a crazy mad Man scientist.

A flashback when Sonic met Mr robotnik which now he calls him eggman.

Sonic (Vo): that's a new friends.

A flashback when he first met tales and his enemy turned friend knuckles.

Sonic (Vo): beat the mad scientist again and got a new power up with the chaos emeralds.

And finally a memory shows him fighting eggman's big robots and being super sonic for the first time.

Sonic (VO): pretty much everything was normal for me. Until one thankful day...

Then we're at the bukowski house. Tom and Maddie was making dinner for Sonic, Tails and knuckles.

Tom: All right, boys!

Maddie: The food's done!

The three raced down and Sonic got there first. At what Tom and Maddie made were chili dogs.

Sonic: all right, time to Chow down.

They began to eat and talking about family stuff like they usually do. It was a good wife for Sonic after the past couple months. Meaning Tom, fighting robotnik, meeting tails, fighting knuckles and robotnik and so on and so on. It was nice and everybody was asleep. Until Sonic heard a strange noise in the backyard.

Sonic: uh? What was that?

He ran outside and saw this strange hole, kind of like a portal somewhere. His hand was getting sucked in then an instant he was sucked into the portal and the portal closed.

Then the portal opened on the other side and Sonic was Free falling down and he landed on snow.

Sonic: that's... Was unpleasant. Where am I?

Then he heard someone shout somebody's name.

???: Korra!

He raced over there and saw some people with some Powers fighting some ghost.

Sonic: maybe I should help them. What? No. No, you shouldn't Sonic. You don't even know these people. I'll decide if those ghosts need a beatdown.

Then an older man with a tattoo of an arrow on head approached the ghost.

???: spirit, why are you angry with us? What did we done to defend you?

The so-called Spirit looked at him and smacked him away that made Sonic a little angry.

Sonic: Okay, That Spirit needs a beatdown.

She raced down there and did his spin attack on the spirit that knocked the spirit down. Then the spirit got up and sawed Sonic.

Sonic: Did your mommy ever tell you to respect your elders?

The spirit tried to hit Sonic but Sonic with his super speed was dodging the spirit's attacks. She curled up to a ball and gave it another spin attack then he gave the spirit couple of punches and a kick in the face. Then Spirit was going after a woman on the ground and he was trying to get there first until he saw the woman's eyes glow white and she starts to hover. And she was doing well defying this one's spirit, until it grabbed her and slammed her down into some boxes. Sonic was in front of her to defend her against the spirit then she looked up and saw him. Then just went to Spirit was going to attack them some water was circling around it. Then a ghost walked away and disappeared.

???: Go in peace.

Sonic: well... That was something.

???: Korra, are you all right?

Then he sawed the blue creature.

???: Get away from her!

Sonic: Whoa, Whoa! Not the bad guy here!

???: Dad, calm down. It saved me from it.

Sonic: Actually, it's a he. I'm a he.

???: it talks.

Sonic: Again, He!

The girl kneels down.

???: What's your name?

Sonic: I'm Sonic. Sonic the hedgehog. And you are?

???: I'm Korra. Avatar Korra.

She let down her hand to shake sonics and so he did.

Korra: Sonic this is Unalaq.

Unalag: Hello, blue creature.

Sonic nod to him but some part of them did not trust him. He was sort of like Loki from The avengers movie.

Korra: This is my father, Tonraq.

Tonraq: hello and thank you for saving my daughter.

Sonic: Of course dud-- I mean sir.

Korra: And finally, this is master tenzin.

Tenzin: it's a pleasure to meet you, Sonic.

Sonic: You too.

Korra: how are you able to control that spirit when no one else could?

Unalag: as your father could tell you, I have spent my life studying the spirits and learning their ways. All of this knowledge is lost in the south, but I can teach you everything I know.

Tenzin: Chief Unalag, clearly, you're very knowledgeable, but Korra still has much to learn about airbending, and I hope that going to the air temples help her connect with the past avatars.

Korra: Ugh!

Sonic heard and saw that and something told him that she did not want to do that.

Unalag: the air temples will teach her nothing. Only I can give her the train she needs to be a complete Avatar.

Tonraq: I've told you that will not happen.

Korra was about to say something until Sonic beat her to the punch.

Sonic: Whoa, Whoa, Whoa! Let's not argue, let's see what Korra thinks?

Tenzin: Korra, please, listen.

Korra: No, Sonic's right. I'm tired of listening to you-- both of you. You keep me locked up, tell me you know what's best, but both of you were powerless against the spirit attack.

Sonic: I did not say a word like that, but okay?

Korra: I think it's time I had a new teacher.

Tonraq: Now, Korra-

Korra: Unalag Has proven he's the only one who knows what I need to learn. I have to go with him.

Tenzin: Please, I know you're angry, but we've come so far together.

Korra: I'm sorry, Tenzin. This is as far as we go.

Tenzin: it has been a pleasure serving you, Avatar Korra.

He walked away and back to his house. Sonic felt bad for him. The morning appeared and him and Korra was walking back.

Sonic: look, I know I'm new here but, don't you think you went a little bit too hard on a guy.

Korra: I guess, but Unalag has proved that he can teach me what he knows. Him and my father was trying to make me do things and I didn't want to do.

Sonic: I think I know what you mean. Tom and Maddie I love them so much they're kind of like a family to me, but sometimes they can always tell me that using my speed is never the solution.

Korra & Sonic: it's like they treat me like a child.

They both looked at each other surprised that they said the exact same thing. And they started laughing. The amazing job and saw some other people.

Korra: Hey guys! I want you to meet someone. Everyone this is Sonic.

Sonic: Hi.

???: Aww, he's so adorable.

One of her friends were putting them until he said a medium electricity shock that tazed him.

Sonic: I'm a hedgehog, not a pet.

???: Good to know.

Korra: Sonic, these are my friends. This is Asami.

Asami: hi it's nice to meet you.

Sonic: it's nice to meet you too.

Mako: hey.

Sonic: hey.

Korra: and the guy you just shocked is Bolin.

Bolin: nice to meet you.

He got to meet her friends. Sonic was sent in this world for a reason. Trying to find what that reason is, in the meantime he had to get good at his new surroundings.
