Hi everyone this is another 'What If' and this what if is "What If Sonic was Shadow's Younger Brother?".

Disclaimer: I do not own anything...

Summary: The name of this 'What If' says it all...although no one knows that Sonic and Shadow are brothers...and Sonic doesn't remember anything about his past and he believes that there is a connection between him and Shadow...but he doesn't remember...why is Shadow all of the sudden protective of Sonic? Will Sonic regain his memories? Or will he not be able to remember? Find out next on Sonic X! (lol sorry I just had to put the 'Find out next on Sonic X' Note that was me being a idiot...and trying to be funny)...

Anyway please enjoy this what if...

Also this is going along with what happens in Sonic X but Earth and Mobuis are the same planet...Chris might be making an appearance...if I'm in a good mood right now.

Also happens after the Shadow Saga but before the Moon Saga...also Shadow made it back to the ARK with Sonic and did not fall...and he is now living at the Chris's house/mansion but he's still the same grumpy hedgehog that we all know and love...anyway I'm going to shut up so you can read this.


*Sonic's POV*

I'm sitting (more like laying) on a tree branch looking at the sky, thinking about my past...and why I can't remember any of it. Also I'm thinking about how much me and Shadow look alike...it's kinda scary but also I feel like I've known Shadow my entire life. "Hello Faker." I jump "AH!" I whip around and Shadow's standing right there...with that stupid little smirk on his face.

"Hiya Shads." Okay that's weird why hasn't he tried to strangle me yet? Usually he's tried to kill me after I call him that...wonder why he hasn't killed me yet. "Shads you okay?" He growled and then glared at me. "It's S-H-A-D-O-W, Shadow. Must I spell it again?" "Ouch Shadow...I think that one hurt physically." "Shut up Faker." I pouted.

*End of Sonic's POV*

*Shadow's POV*

I'm watching Sonic. No I am not a stalker! I'm just...watching out for my little brother...it's kinda hard to believe that me and Fak- I mean Sonic are related...I've regained all of my memories...it was kind of shock a to learn that the very hedgehog I hated and almost killed multiple times is my little brother...kinda hard to believe that there is actually another Ultimate Life Form. But I do know one thing, I would and will give my life for my baby brother. "Hello Faker." I said as I walked over to him...sure I waited until I was almost right next to him to say hello.

He jumped. "AH!" I smirked. He whipped around "Hiya Shads." a thoughtful look appears a cross his face like he's wondering why I haven't tried to kill him yet. "Shads you okay?" I growled and glared at him. "It's S-H-A-D-O-W, Shadow. Must I spell it again?" He looked a little hurt.

"Ouch Shadow...I think that one hurt physically." "Shut up Faker." He pouted...he looks adorable when he pouts.

I smirked again. "So what brings you here Faker?" I asked.

"Nothing...just thinking." "Really? You can think?" He faked a hurt expression. "Ouch!" It's kinda funny...how we act like brothers and he doesn't even know that we are.

"Ya know what Shads?" "What? And it's Shadow not Shads." "I was thinking 'bout how you and I look alike...and how...I feel like I've known you my entire life." He blurted out the last few words really fast but I heard and understood him. "Faker?" "Yeah Shadow?" "What's your very first memory?" "Um...me waking up in a field half dead...why?" "I need to go." I used Chaos Control and disappeared.

*End of Shadow's POV*


*The next night and Sonic's POV*

I had a weird dream...it was a blonde girl with blue eyes and a black and red hedgehog...why did the black and red hedgehog look and sound familiar in the dream? Who was the black and red hedgehog? Who was the girl? "Hello again...Faker." "Gah!" I jump and whirl around again. "Dang it Shads you need to stop sneaking up on me like that." He smirked "No can do. So what brings you to a pond in the middle of a forest?" "I uh...um...I had a weird dream and I've been seeing things in my head...they feel like memories." He raised an eyebrow.

"What was in that dream and the weird things you've been seeing?" "Well the dream I saw a blonde haired girl and a black and red hedgehog...like you...they were taking care of a younger me... a lot younger me...and then the things I've been seeing...I was on the ARK with the same two people...I'm not going insane am I?" He froze. "Was the girl wearing a blue dress, a blue hair-band, and did she have blue eyes?" "Yes, yes, and yes."

"Faker...that girl you saw...was Maria."

*End of Sonic's POV*

*Shadow's POV*

"Faker...that girl you saw...was Maria." His eyes widened in shock. "That means...that means that you're the black and red hedgehog?!" I nod. "Yes." "Wait a second...you knew! But how? I thought you lost your memories?" "I did but I regained them a few days ago. Well bye Faker." I turn to leave.

"Wait Shadow!" I stop. "What?" "Am...am I seeing your memories? And if I am...then why me?" I smirked "Faker that's for me to know and you to find out or remember." I used Chaos Control and disappeared.


*A few days later...when fighting Egghead and Tails' POV*

"Sonic don't run!" "Why Tails?" "The missile...but it's not just any kind of missile once it hunts speed! So it was made to hunt you down so if you run really fast you it would track you and you alone!" But Sonic had already took off...and the missile took off towards him and since Sonic was watching the missile he didn't see the wall in front of him...he ran into the wall.

"Sonic!" Amy cried out as the missile got closer to Sonic. I saw Shadow's head whip from the robot he had been fighting to Sonic, he used Chaos Spear to defeat the robot then he ran in front of Sonic and took the missile. "What!? No! That wasn't supposed to happen! It was supposed to hit Sonic! Not Shadow!" Eggman raged.

Shadow stood up so did Sonic (who had a look of pure shock on his face) Shadow then pulled out his green Chaos Emerald and said. "Chaos Heal (I don't know if Chaos Heal actually even exists but if it doesn't it does in this)." Shadow's body was covered in a green light as his wounds were healed.

"Shadow why did you take that missile for Sonic?" I asked him. "Because Fox." Then Shadow took off and started destroying more robots than Sonic did the same.

We beat Eggman that day...but as to why Shadow took that missile for Sonic... We probably will never know.


*Same day as they fought Egghead and Sonic's POV*

I remember...when Shadow took that missile for me...I remembered everything in that second. It's hard to believe that me, Sonic the hedgehog is Shadow's little brother. So I guess that means that's why me and Shads look a lot alike...but I don't remember why I woke up in the field alone...without any memories.

"Hello Faker." Shadow...my brother. "So I'm guessing you weren't gonna tell me huh Bro?" Shadow's face...priceless. Then his face turned back into its emotionless expression..although he seemed a little happy. "You remember I take it?" "Yup... Kinda hard to believe I'm you're little brother." "So...do you want to tell you're friends?" "There's not just my friends Shads...their yours too." "Really?"

"Yeah...I mean you're the one who refuses to be friends or well everyone considers themselves you're friends." "I doubt any of them will believe that you and I are biological brothers." "Well...I have a question." "What?" "Why am I blue and you're black and red?" "It seems the hedgehog who we both got our hedgehog DNA from was blue and well...I'm guessing that you look like her and I look like Black Doom." "Yeah...I don't remember that...although I don't even remember how I even woke up..on Earth alone."

"The Bio-lizard." Shadow spoke with so much hatred in his voice. "What about the Bio-lizard?" "Well...as you may or may not remember you were quite adventurous...almost got yourself killed a lot."

"I remember that...you and Maria always scolded me for doing that." "Yeah...well one time when you were as me and Maria called it 'Adventures of Sonic Hedgehog' you went into the same room as the Bio-lizard when Professor. Gerald was still creating it." He froze like he was in a memory. "He was still creating the Bio-lizard?" "Yeah...and well...Gerald wasn't in the room, he was getting something he needed to finish it so it wouldn't attack anyone...but there was one person it never attacked and that was Gerald... and...the Bio-lizard attacked you... and me and Maria and Gerald had heard the alarm that would go off if the Bio-lizard would attack anyone...and as soon as the three of us got there...you had already used Chaos Control...we got there just to see you get sent somewhere."

I saw his face...he was close to tears. "Shadow...I'm sorry." "For what? It wasn't your fault." "Yes it was...I was the one who used Chaos Control."

He smirked "Yeah...so you wanna tell our friends?".

*End of Sonic's POV*

*Shadow's POV*

"Shadow...I'm sorry." I am confused why was he apologizing? "For what? It wasn't your fault." "Yes it was...I was the one who used Chaos Control." I smirked "Yeah...so you wanna tell our friends?" Sonic grinned "Heck yeah!" I smiled. "Well then I believe that they are on Angel Island, probably wondering why I took that missile for you earlier." "Then let's go!" I used Chaos Control to take me and Sonic to Angel Island.


*At Angel island with everyone and Amy's POV*

"I'm worried about Shadow." Rouge stated. "Of course you're worried bat girl! He's the only person in this world you care about!" Knuckles said angrily. "That's because Shadow's like a brother to me Knuckles!" Rouge yelled at him. "Enough!" Tails yelled "We need to find out what's been going on between Sonic and Shadow, they both has been acting weird around each other. Shadow's been protective of him and Sonic's been different he's been passing out and he's also been having nightmares a lot too." Tails finished.

"Do you think Mr. Shadow did something to Mr. Sonic?" Cream asked. "I don't think Shadow's evil anymore Cream...I doubt he would do anything to hurt Sonic...and with how he's been? I doubt he'd hurt Sonic. I mean he took a missile for him." "You are correct Rose I wouldn't hurt Faker." "Ah!" Everyone jumped and whipped around to see Sonic and Shadow. Sonic barely able to hold in his laughter and Shadow smirking.

"Good one Shads!" Okay...why isn't Shadow glaring at Sonic? "Okay...Shadow what's wrong with you?" "What do you mean Rouge?" "Well Sonic he's not glaring at you...or trying to kill you." "Well um...Tails?" "Yeah Sonic?" "Do you remember when I told you I woke up in a field all beat up and everything? And I also couldn't remember what happened?" "Yeah I remember that. That was after you had told me that you hated water...and I say hated because you won't admit that you're really afraid of it."

"I am not afraid of water! I just...don't like getting wet. But anyway about that." Tails' face lit up. "You remember!?" Sonic nodded then Tails said (he was very excited) "Everything?" Tails asked. "Yeah...I remember everything...including that I have an older brother." "You have an older brother? Where is he?"

"Um well Tails you see...I uh wasn't born." Everyone except for Shadow stared at Sonic. "What are you saying? Are you saying that you're like Shadow? That you were created?" "Yeah...and well you see...my creator was...Professor. Gerald."

*End of Amy's POV*

*Sonic's POV*

"Um well Tails you see...I uh wasn't born." Everyone except Shads stared at me. "What are you saying? Are you saying that you're like Shadow? That you were created? Tails asked me. "Yeah... and well you see...my creator was...Professor. Gerald." Everyone's mouths; (Except for Shadow of course...because he's just that awesome) dropped open. "You were created by the same person who made Shadow!?" "Yeah...actually Shadow is the older brother." I thought everyone's eyes were about to pop out.

Then Amy said "So...that's why Shadow has been protective of you lately?" "Yes...that is why I have been...because I remembered everything including that I had a little brother who...because of an accident disappeared and his name was Sonic and he was blue." "Also Tails?" "Yeah?" "Those dreams and when I'd pass out? Those were me remembering those dreams I had were my memories." Then I froze when I felt Shadow's eyes land on me when I said I'd pass out.

"You never told me you were passing out every time you remembered something!" Shadow said while glaring at me in a way that made me feel uncomfortable. "Yeah? So?" "Faker I'm you're older brother I'm supposed to be worried about every single thing that has anything to do with you." "Yeah which it's kinda funny that the Ultimate Life Form's little brother is the person he's tried to kill a few times." Knuckles said with a smug grin on his face.

"Echidna! You did not just go there!" "Well I just did Shadow!" "Shut up Echidna! Sorry I couldn't remember that I had a little brother!" "It should be Sonic you should be saying sorry to! Not me!" "Echidna! Shut! Up!" "HOW ABOUT BOTH OF YOU SHUT UP!" I yelled.

Everyone stared at me because I never have yelled like that before, ever.
