A Loud House and Sonic Crossover. Why not? Since I'm a fan of both franchises, this gives me a great idea to make a fanfic about them. This story will also be a long one so, there's that. And this is my first crossover fanfic, so bare with me.

Edit A/N:

Gosh, it's been, what, like two years since I'm doing fanfics? See, 2020 sucks. Like really. A lot has happened this year and I've been focusing on my DA account. But I've decided to take a long break from there and put my main attention here. Also, the following chapters I'm going to edit is gonna change at a certain amount, every since I've read the Sonic IDW comics (which y'all should read if u haven't already, it's really great) I wanted to tie does events in my story. So, spoilers, this fanfic takes place between Issue #31 and Issue #32.

Sonic the Hedgehog is owned by SEGA

The Loud House is owned by Nickelodeon

Anyways, enjoy the chapter!

It's was a nice and calm day in Green Hill. The little animals are just going by their business, enjoying the yellow sun and fresh air. Then out of nowhere, a blue bur ran past them. They all knew who it is. They all wave at their hero, as he passed by. Then the blue bur come to a halt. It was none other then Sonic the Hedgehog. It has been crazy for him these past few months, after what happened with Metal Overlord, Eggman almost affecting all living creatures of Mobius with his Metal Virus, a new face named Dr. Starline releasing the Deadly Six and other villains to help with Eggman's plan, Sonic getting his memory wiped and was sent to Blaze's dimension and more.

But that was all in the past, eventually, with the help of Blaze, Sonic got his memories back and went back home to defeat his long time foe once more. The resistance were rebuilding the world, again...they just don't get a break, can't they? Our blue hero was thinking about where to go next until he heard ringing from his communication watch. He press a button, reviewing a screen to see his best friend, Miles 'Tails' Prower, just call him Tails instead of Miles, he hates that name.

"Hey Sonic, how are things looking out there?" Tails asks his best friend.

"It uh...seems empty for the most part, but I'm gonna keeping running around, see what's up." Sonic replied.

"Heh, you can never be too careful. So, I was thinking that you could check out City Sunset Avenue, heard that there's some badniks there and-" Before the fox can continue, Sonic can see something in the distance.

"Hold up...I think I see something." Sonic said, trying to see who it was that was coming closer towards him, Tails got worried by this.

"Be careful Sonic, it could be a tra-" Tails was interrupted again.

"You worry to much, Tails, I'm sure it's just-" Then static was coming from Tails watch.

"Hello? Sonic, do you copy?" Tails said, hoping that Sonic will reply. But he didn't. "This is bad...I have to tell Knuckles about this." The fox then left in a hurry.

"Hey, egghead, long time no see, huh?" Sonic said, as his greatest villain was floating on his vehicle. The mad genius himself, Doctor Robo-I mean, Doctor Eggman.

"Well hello, Sonic. We meet again! I hope you didn't miss me that much, see, after my last defeat, I was working on something that can finally get rid of you for good!" Eggman said, while the blue hedgehog scoffed at this.

"Sooo, what's it gonna be this time, doc? Ever get tired of trying to destroy me?" Sonic asked.

"Let me think...nope! Also, thanks to that Dr. Starline, I've did a little research on the Warp Topaz. " Eggman smirks, pressing a button behind him. "Since you always ruin my plans, I created something that will put a end of your heroic acts!" He added.

"How many times are you gonna do this, doc? You know, we could just drop all of this right now, you could be a better person, like Mr. Tink-" Before the hedgehog can finish, the doctor interrupted.

"HEY! I thought we'd agreed to never mention that name again, now you really gonna get it!" Eggman growled, pressing a button behind him.

"When did we every agreed to do th-" Sonic was interrupted again, not by Eggman, but a huge force field that was sucking in everything that it could.

"Woah, what the heck is going on!?" Sonic asked in shock. He try to run away from it, but the force was to strong. He was then sucked into the portal, as it closed.

"Hahahaha! Goodbye, Sonic. Forever!" Eggman laughed. All of a sudden, two robots came out of Eggman's Egg Mobile, those two were none other than Orbot and Cubot.

"Um, boss, didn't you did the exact same thing with Sonic not to long ago?" Orbot asked, much to the robot's confusion.

"Yeah, didn't he just came right back anyway?" Cubot added.

"Not this time! I send that rodent to unknown universe where there are no resources to able to bring him back!" Eggman answered. "I'll admit, I'm gonna miss our fights, but I can't keep him destroying anymore of my future plans."

"I mean, guess that make sense, all things considered..." Orbot said, scratching his metal head.

"Of course it make sense, dude! What are we going to do now, boss?" Cubot questioned.

"Oh ho ho, I can't tell you too much, but...why have an Eggman Land...when you can have a Eggman World!" The mad scientist laugh once again, as you can hear his devilish laugh through out Green Hill.

Inside the portal...

Sonic was flying around through space and time for a few minutes. Until, he saw an opening in front of him. He close his eyes, because he can tell that this will be a hard fall.

In Royal Woods park...

It was also a beautiful day in Royal Woods, Michigan. In the park, there was no one around for the time being. Then a portal appeared, just a few feet from the ground. Then, Sonic came out of the portal and landed on the ground with a thud. The portal on top of Sonic then disappear out of sight. Sonic was laying in the ground, groaning.

"Ugh...w-where am I?" Sonic said, as he got his head up looking around. "Well...I didn't lose my memories, that's a start. Dang it, Eggman, when you'll ever learn? " He added. The hedgehog then got up on his feet. While he was still looking around, he then saw pigeons near by.

'Huh. They kind of look like the flickies back at home. Maybe they know where I'm at.' He thought, as he approached them.

"Uh, excuse me? Do you know where I'm at right now?" Sonic asked. The pigeons just stared at him for a few seconds, until they all fly away. "...Rude. Man, the doc got me good, I'll give him that...but he'll get what's coming to him. I do need to find some help first."

Then just a few yard away from the hedgehog, he saw two boys walking towards him. Sonic quickly ran behind a nearby tree, listening to the two boys.

'Uh-oh. I can't let my cover get blown, don't know if they're dangerous.' Sonic thought, as he raced behind a nearby tree.

The two boys are Lincoln Loud and Clyde Mcbride. They where walking home from school, excited that their Spring break is finally here.

"Man, finally spring break is here!" Clyde said, while throwing his arms in the air.

"I know, right!" Lincoln replied to his best friend. "So, wanna hang out later, do something maybe?" He asked.

"Of course! But, remember what happened last time?" Clyde asked to Lincoln. The white haired boy remember the time where he and Clyde where trying to make their spring break fun, until school comes back. It didn't go exactly as they thought. But it was fun, despite Lincoln getting attack by a parrot.

"Yeah...let's not do that again. Lucky for us, I'll try to think of a new plan that probably won't fall flat on our faces." Lincoln replied.

"Sounds like a plan to me!" Clyde happily said. Before he can continue, his watch then beeps loudly. "Opps, sorry, I have my usually therapy with Dr. Lopez, don't wanna be late with that stuff."

"Alright, good luck with that! I'd promise to help Lola with something." Lincoln said, waving at his hand as the two went their separate ways. Little that the two know, that a certain blue hedgehog was watching them.

'Hmm. Well, I guess they're not bad. They are kids after all...' Sonic once again thought. 'I guess I can tell that kid in the orange shirt where I'm at...' He added, as he ran up behind Lincoln and poke him by the shoulder.

"Hey kid, any idea what planet I'm at right now?" Sonic asked. Lincoln then looked behind him.

"Uhh, what are you tal-" Before Lincoln finished, he was shock to see a strange two foot hedgehog, has blue fur, two legs and was wearing red shoes. "What the- who the heck are you?!" The boy yelled.

"Woah, woah. Calm down kid, I'm not bad!" Sonic said, trying to calm him down.

"You can talk!?" Lincoln yelled again, getting freak out.

"Of course, doesn't anyone?" Sonic replied. Lincoln was still in shock.

"O-okay, Lincoln. G-Get a hold of yourself...it's just my imagination." The boy said, breathing in and out between sentences. "Or maybe i-it was a side affect from one of Lisa'a experiments?" He added. Sonic was confused at this.

"Uh...no. I'm all real. Here." Sonic replied, as he touch Lincoln's shoulder again. The boy shove Sonic's hand away from him.

"This c-can't be real! Uh, hahah, nice one, Luan, you got me!" Lincoln chuckled, thinking that this was his sister's doing.

"What? Who's Luan? I'm Sonic the Hedgehog!" Sonic responded.

"Wait...you're a hedgehog?" Lincoln asked again.

"Well, yeah I am. Just look at my spikes." Sonic said, as he turn around to show him his back.

"But...you walk on two legs..." The white haired boy said, still looking confused.

"Of course, why wouldn't I-" Before Sonic finished, he thought of something. "Wait...hedgehogs don't walk on two legs, in your universe?"

"Uhh...no. None I can think of." Lincoln responded. "Also...what do you mean by...'universe'?" He added.

"Huh...guess that Warp Topaz Eggman used send me to a universe where there's nothing like me..." Sonic said, while trying to think what's going on.

"What? Eggman? Are you...from another universe?" Lincoln asked Sonic again.

"It looks like it." Sonic replied. "Maybe that's a reason why you never seen a talking hedgehog before." The hedgehog added.

"Well...what are you doing here? Are you lost?" Lincoln questioned the hedgehog.

"As a matter of fact, I am. Can you help me?" Sonic asked. Lincoln then started to think. This was definitely not the way he thought his day would turn out. I mean, who could blame him? Not every day you get to see an alien hedgehog from another universe asking for help. But, who knows? Maybe this could be an exciting new adventure (wink) for him.

"Hmm. Well...I do have a sister who is a scientist. Maybe she can help you." Lincoln responded. "But there's still many questions I still have." He added.

"Well, okay. Shoot." Sonic said, crossing his arms. Looks like Sonic is yet in another predicament, how he's gonna go home? How will the rest of his friends react that he's gone again? More importantly, how much damage will Eggman cause back in his world? Guess time will only tell.

Now this was fun to do! In the next chapter, Lincoln is going to ask Sonic questions and he'll try his best to answer them. And hopefully, Lisa can help Sonic to his way home. Instead of experimenting on him...

Welp, gotta juice!
