I used to write Sonic fanfics for years until I moved onto Miraculous Ladybug. My co-writer wanted a crossover of it and we worked together to write this. He still has his Sonic fan in him while mine became weak. So I needed his help and it was good to feel like writing Sonic fanfic with a crossover.

It was sunny in Mobius world as their favorite blue dashing devil with the speed to run faster than any animal in the world. For years this hedgehog has beaten the mad doctor wanting to build an empire all to himself but fails constantly because of the blue hedgehog with the speed.
And so, the blue hedgehog was running in Green Hills, going from the loop-da-loop and into the palm trees to get to his best friend's workshop.
"Hey Tails, sup?" He asked his fox friend.
"Hi, Sonic" Tails smiled seeing him.
"No Egghead in sight. I don't know if I should be worried or just think he's running out of ideas to kick my butt" Sonic said before going to the fridge to grab a soda.
"Eggman is always unpredictable. Well, the metal virus was one out-of-control thing he made" Tails recalls the metal virus plague.
"No more zombie apocalypse again. Total nightmare, bud. Never again" Sonic sips his soda.
"Yeah, it took you and Silver to clean our planet from the virus and send it to the sun" Tails said.
"But I ended up in Blaze's dimension getting amnesia but she helped me to remember," Sonic said.
"And here you are back to our Sonic again. Anyway, I've been working on a device to open portals to another dimension. Just in case something bad happens if Eggman tried to send you to a dimension to get rid of you" Tails built an invention.
"Thanks. I'm sure it accesses Mario's world" Sonic said.
"That too. I programmed it for that. And how's Amy doing with Cream?" Tails replied.
"Doing just fine" Sonic said, sipping his drink, "I gotta admit she's maturing more than chasing after me in the past" Sonic said.
"Especially with that hammer when she's mad" Tails snickered.
"Ah, yeah. But I have heard enough to rescue her from all kinds of threats. Right now, she and I are simply platonic friends" Sonic said.
"You sure about that? You seem to miss the old her" Tails snickered before putting his invention away.
"Well, when she was a fangirl" Sonic shrugs.
"Whatever Eggman is planning, I hope it's not something worse than the metal virus. His madness is gonna get him, us, everyone, the entire world killed" Tails said.
"Yeah, but we make it through it somehow each time. I'd do anything to save everyone I love, especially you Tails. You're like a little brother to me" Sonic replied confidently.
"You inspired me a lot" Tails smiled.
"We all inspired everyone to do the same," Sonic said.
"Indeed Sonic, we did," Tails said.
"Anyways, I'm gonna do my runs. Always like the wind" Sonic sped out.
"Good luck, Sonic" Tails resumed working as his friend ran.

In another world dimension of Paris, the death of Monarch has been a victory as well as Gabriel who everyone believes risked his life to save the world. But the butterfly miraculous has not been recovered since it disappeared like it was gone. Unknown to everyone, it now has Cerise as its new holder. Even if she did get her revenge on Gabriel before he died, now her next target is Marinette Dupain Cheng who exposed her true colors in front of the entire school, and she abandoned her Lila Rossi identity.
The newly restored Miraculous Team was keeping Paris safe from all kinds of threats but hadn't yet faced any of her akumas. It's been months now since she's learning to do akumas but unaware that something scared her before attending the new school. Whatever it was, it didn't stay for long.
With Adrien and Marinette, they were discussing the latest game they played together. The Miraculous Super Brawl has uploaded DLC of Argos since he became the newest member of the team. His special attacks include slashing with his razor-sharp fans.
"I gotta hand it to you, Marinette. The school without struggling to get good grades is doing great. No Chloe or Lila to ruin lives again. Yet I'm still struggling with what to do with my life" Adrien said.
"You could always start doing art" Marinette suggested.
"I'll keep that on my bucket list," Adrien said.
"It's so nice of Nathalie to be your legal guardian and allow me and our friends in the mansion. Especially Amelie and Felix moving here since that's their dream. To honor your parents" Marinette kissed his cheek.
"Yeah. But you and our friends are like family to me" Adrien gently nibbled her neck at how much he loved her.
"One big family that is" Marinette moans a little.
"I wish I knew what it's like to be a real true father. But I'm still too young for that. I mean you always dream of having three kids with me. It's cute" Adrien chuckled a little.
"Well, I do. But we're only 14" Marinette said.
"Yeah. I can imagine us at a wedding with a true love kiss like a fairytale. Can you imagine that?" Adrien said.
"Yeah, I do" Marinette chuckled at the thought.
"And you as my lovely and gorgeous princess" Adrien teasing her with lovely imaginations.
"Yeah, my Prince Charming" Marinette teased him back.
It wasn't long until an Akuma alert alarmed the city, "What the?! There's still akumas?!" Adrien gasps.
"I thought it was over," Marinette said.
"Probably not," Adrien said before knowing that Cat Noir needs to come out eventually, "Stay here. I'll get some help" He made her stay in the alley.
"Be safe Adrien!" Marinette hides behind a barrel once he is out of sight, "TIKKI SPOTS ON!" She transformed into Ladybug.

In the Mobius world, a black and red hedgehog is alone as always, even if supposedly likes hanging out with the robot and the sneaky treasure hunter bat, he likes solitude for himself. After years of fulfilling his promise to his only deceased human friend who was like a sister to him, he still hasn't interacted with other humans in a while because none of them are like Maria Robotnik. None of them. He saw one butterfly with her dress' blue color land on his finger.
"You would have loved this world, Maria. It would be like a dream come true" He said softly before it flew away.
"Awww….such a lovely soft side from Mr. Dark and Gloom" Rouge the Bat hanging on the tree branch.
"Hmph! Don't get used to it, Rouge. I'm the—" Shadow didn't finish.
"The Ultimate Lifeform. Yeah, I know. You say that endlessly for years like immortality makes you never forget that. Sheesh" Rouge jumps down.
"Like that matters, Through the years it's been challenging Eggman after we left him," Shadow said.
"Come on, handsome. You've been in the shadows far too much to miss out on the fun" Rouge said.
"You're suggesting I'll challenge Faker in a race?" Shadow raised a brow.
"No. You both end up as a tie every time. What I mean is you need to stop being so low self-esteem. Yes, I know you tell me your only deceased human friend was the only one to treat you as a being than a weapon. There's gotta be someone out there to treat you like she did" Rouge said, pickpocketing his chaos emerald.
"Give me that!" Shadow snatched it, "Humans are not easy to talk to, bat. No one is like her and I'm better off as to not lose another human friend again" Shadow walks away in a scoff at that bat's annoying nonsense.
"You always have use for support. But suit yourself if you don't want company" Rouge then takes flight.
Shadow shook his head that she was wrong. No human will ever understand him. Not even the insane Eggman would.
