Five minutes prior

"Belle, are you alright?" Midoriya asked

"I'm fine." Belle said, "Is there anyone else here?"

"I'm here." Mineta said

"I'm here too." Tsu said

"Alright, so we need a plan." Midoriya said

"Uh guys there's villains in the water." Mineta said

they looked and there were a good hundred villains in the water

Belle pulled out a Taser, turned it on and dropped it in

A few seconds later every villain floated up

"There WERE villains in the water." Belle said

She then pulled out a comically large fan out from one of her pockets

"HOW?!" Midoriya asked

"Did your dad invent hammer space?!?" Mineta asked

"Y-Yes." Belle said

She turned it on and the boat they were on began to move

Soon they reached the mainland

"Okay, so those are real villains." Midoriya said, "We need a plan of attack."

"Are you nuts?!" Mineta asked, "Let's just wait for the pros!"

"The pros won't be here in time!" Midoriya said

Just then the ground began to shake

"But someone else is." Belle said

They watched as a 3 eyed humanoid hedgehog jumped out of the ground and landed in front of the villains before being followed by two robots

Shortly after Sage came out lifting a blonde girl up

"Sage!" Belle said

"Hello, sister." Sage said, "I have brought us more family."

"You really aren't going to stop this are you?" Belle asked

"No, but she really is family just not siblings." Sage said

"Hello, I'm Maria Robotnik!" Maria said

"Isn't that your last name Belle?" Tsu asked

Belle froze


"Nomu! Kill this brat!" The hand villain said

Terios immediately turned his hand into a gun and began to tear the nomu apart with flesh bullets as Gemerl and Sigma began to help Mecha and Metal out

"Hey watch where you're swinging!" Aizawa said as he ducked under a punch from Germerl

the nomu regenerated and began to try to attack Terios who easily dodged

Kurogiri then appeared next to the hand villain

"Tomrua Shigaraki I have incapacitated thirteen however a student escaped." Kurogiri said

"WHAT?! If you weren't our way out of here I'd have killed you!" Shigaraki said

"GET A LOAD OF THIS!!" Dr. Eggman yelled as the hard-boiled heavies arrived

"Well then...Let's break the number one hero's heart." Shigaraki said before lunging...

Towards Maria,

terios saw him immediately noticed and kicked him away

His body began to distort and change

"Keep your hands AWAY FROM MY SISTER!!!" Terios yelled as he transformed into...

"...Devil Doom..." Dr. Eggman said upon seeing Terios's transformation

Terios raised his fist

"Nomu catch it!" Shigaraki said

The nomu shoved Shigaraki away and attempted to catch Terios's fist...

Only to get Flattened into a fine red paste, unable to regenerate

Terios readied a second attack aimed at Shigaraki

"Kurogiri! We need to leave!" Shigaraki said

Kurogiri warped the two away just as Terios's fist collided with the ground

"Terios! You did it you scared them away!" Maria said as terios began to transform back

Dr. Eggman finally noticed the alternate version of his cousin

There were slight differences compared to the one shadow the hedgehog knew

One she had the Robotnik nose albeit smaller than the males in the family

Second here hair was a bit lighter presumably from hanging out with this terios

And finally, her eyes were green rather than blue

Maria hugged her little brother once he was in his smaller form once more

"Terios that was incredible!" Maria said, "What was that?"

Terios looked at his clawed hands his gloves and shoes destroyed from his transformation

"I'm not sure." Terios said

"That was devil doom a form taken by black doom in combat." Dr. Eggman said as he approached

"Who are you and why do you look like the professor?" Terios asked with a glare

(Woah his glare is more oppressive than my father.) dr. Eggman thought to himself "I am his grandson after all."

Maria gasped

"You're my cousin?" Maria asked excitedly

"That I am!" Dr. Eggman said "I am ivo robotnik! And you've already met my daughters. Sage and belle."

Maria gasped

"Oh my goodness! You're adorable!" Maria said

"Thank you." Sage said

"Thank you?" Belle said confused

it was that moment all might showed up

"I AM HERE...late?" All might said

Terios got into a fighting position but was stopped by Belle

"Don't worry he's a good guy!" Belle said

"Fine." Terios said

All might approached

"Doctor I see that most of the students are missing." All might said

"We were separated by a villain." Midoriya said chiming in

"I see." All might said before looking at the newcomers "And who are they?"

"This is my cousin, Maria and the ultimate lifeform created by my grandfather. Meet terios." Dr. Eggman said

"Ah yes, you mentioned your grandfather was searching for immortality during your theme park's grand opening." All might said

"YOU HAVE A THEME PARK!?" Maria asked

"one of the greatest in the world!" Dr. Eggman said, "I'll have to take you some time Maria."

"Really?!" Maria said "Yes!"

"So they are staying with you?" All might questioned

"Of course!" Dr. Eggman said, "That includes you two!"

Germerl and Sigma looked at him in confusion

"Come on it will be fine!" Maria said

"All right then." All might said, "I am going to defeat any remaining villains."

"Very well I shall take Maria and Terios to safety." Dr. Eggman said as all might left

He then whispered to sage

"Grab all the notes down there."

Sage nodded and teleported away

"Now then. Belle, metal, mecha. We're leaving." Dr. Eggman said

Sage reappeared and then they left


"So where is your house ivo?" Maria asked

Dr. Eggman simply smiled and snapped his fingers and then they were in the death egg

"I-is this the ark?" Maria asked

"No, it's the death egg!" Dr. Eggman said

Maria gasped

"Like Star Wars!" Maria said

"Yes exactly. Though we will build an actual place since you haven't been on earth in forever." Dr. Eggman said, "For now take a rest you'll be bunking with Belle Maria, terios you will bunk with metal and Germerl and Sigma will bunk with sage."

"Alright then," Terios said as metal began to lead him to his rooms

When he opened the door he saw lots and lots of Miku merchandise

(What the fuck?) terios thought to himself


Bonus

"Father I was looking over great grandfather's notes and...Found something..." Sage said

"What?" Dr. Eggman asked

Sage handed her father the notes

"Day 120: Every time I look at black doom I feel something... Not fear or scientific curiosity (Though that might happen later down the line...) something akin to what I felt with my late wife-"

Doctor Eggman immediately removed his glasses and cleaned them

"So my eyes are correct... please don't be more." Dr. Eggman said

He looked at the next note

"Day 125: So I decided to ask for love...And to my surprise he accepted!-"

Dr. Eggman immediately grabbed his forehead

"Please Gaia no..." Dr. Eggman said before grabbing the final note

"Day 135: Well I haven't had that much fun in ages who knew black arms biology was so fascinating!-"

"NOOOOOOO!!!" Dr. Eggman said "GOD DAMNIT!"

he turned to sage

"Sage delete reading these notes from your memory." Dr. Eggman said

"Already done father." Sage said

"Now these must be destroyed!" Dr. Eggman said

In an instant the notes were grabbed from his hands

he turned and saw metal with the notes

"Ah metal please destroy those." Dr. Eggman said

"...I'm posting these to our world's Twitter." Metal sonic said

Dr. Eggman's eyes went wide

"METAL NO THOSE CAN'T SEE THE LIGHT OF DAY!!" Dr. Eggman said


Shadow the hedgehog was scrolling through Twitter while eating coffee beans when he saw Rouge had @ him in something

"What's this?" Shadow asked himself

it was from Belle's account

"A gift from an alternate universe!- Belle"

"Suffer. - Metal Sonic"

And it was a picture of some notes

Shadow read them

.

.

.

"SON OF A FUCK!!!!" Shadow yelled after choking on his coffee beans

.

.

Some said you could hear Sonic's laughs from space

Sage definitely has one of those big princess beds

that's it for now see you next time
