Summary
How far would one go to save {family}? Loved ones? Those whom slipped through one's fingers in a hazy, catastrophic mess of fire and bullets? How long can one fight against the odds – against fate – against programming?
To Maria, the answer was simple: far enough. She will CLAIM this second chance, protect Shadow from vile monsters, defend Grandpa from terrible things, save the ARK, and make it happily to the Earth!
To Gerald, the answer was complex: anything for his little ones. However, the line to play between what he had to do to protect from the machinations of G.U.N. was opposite of what his precious granddaughter would want.
To Shadow, there was no question: he was already doing what he had vowed to do. He's back to where it all begun, filled with knowledge on how things went wrong; how to make things right. He'll save everyone, even those that perished in his future.
---Arc 7---
At the end of the long road, there can be the greatest of hope.
And the deepest pits of despair.
The bitterness of salt.
And the sweetness of love.Whatever the case, Gerald Robotnik soon discovers one barren truth: wishes are eternal.

Summary
*‘’YOU CAN’T JUST TAKE HER LIKE THAT!’’*
A voice echoed through the cold hallways of the ARK. Gerald Robotnik, greatest scientific mind, frowned at the visible anger pouring out of his son’s voice, his grip on his table as the screen from the transmission buzzed. He could count with one hand the amount of times that he had seen or heard one of his boys truly infuriated. It really hurt to know that his own father was the cause of his distress. But he had to understand, for the sake of his daughter’s future. She is unable to just stay on earth with a sickness that would slowly consume her until she tragically succumbed to it. He couldn’t allow it, he would *not* allow it. Maria was a strong and brilliant girl, his most valuable treasure in life, nearly everything the oldest robotnik had ever done so far had been for her, to grant her the opportunity to live in a peaceful world that she could thrive in, a world where she could inhabit and find happiness within. Fate was cruel, and it simply broke his heart to see someone so wonderful as his granddaughter pay the price for it

Summary
She's spent forty years fleeing her cousin. Only now does she dare look over her shoulder.
Once upon a time, Maria Robotnik wanted for nothing... So she thought. Ivo's tantrums seemed a small price to pay for her cushy life in Grandfather's manor on Earth, cured of her illness and the ARK signed over to the government in exchange for their silence. What did a young boy's childish insults matter, as long as the family was together?
As Gerald was often fond of telling the budding genius: a broken toy is nothing worth pitching a fit over.
Perhaps it's fate, then, that the Eclipse Cannon requires two sets of fingerprints to fire.
Be his friend, Grandfather told her. A cruel promise she cannot keep.

Summary
(Highschool AU written by a homeschooled kid who's never stepped foot in an actual public school)
Ivo Robotnik has never even held hands with someone, although he's found himself attracted to a few guys and girls despite his utter indifference towards humanity otherwise. At least until he met Aban, the most gorgeous person he'd ever laid eyes on and the only student in this entire school besides his cousin Maria who could actually keep up with his intellect. Plus he makes a hell of a latte for only being sixteen.
Maybe those cheesy romantic teen movies his cousin Maria always watches were on to something after all...

Summary
“Why was this in here with all this trash?”
“It’s not trash,” Maria laughs, “it's Shadow’s little collection. He likes that.”
Addie looks vaguely horrified. She holds the ornament by its string, reexamines it. “It likes this?”
“Mmhm.”
“Why?”
“I don’t know,” Maria says.
“It doesn’t look chewed.”
“Oh, no. I think Shadow is too proper to chew on anything like that,” Maria giggles.
Addie places the ornament on the vanity across the room. “You should be careful with it.”
“I don’t mind, mom and dad send me one every year. I have so many.”
“No,” Addie says, “I meant the experiment. You should be cautious of it.”
Maria frowns. “He’s just a little thing. Barely a lapful. I don’t think he’s dangerous.”

Summary
Gerald Robotnik is the one who discovered the husk. He named it Sonic after it proved useful to Project Shadow. He sent it to Earth to buy himself more time, only to lose Sonic in the end.
Maria Robotnik knew she was going to be close friends with Sonic from the moment they first met. This closeness caused her sickness to flare when Sonic died. Gerald saved her by erasing her memories, and she only remembers Sonic when her dying breath leaves her.
Maria is the person Shadow was made for. She is his sister, and he loves her dearly. He also loves Sonic. He loves them both so much that Gerald is forced to erase his memory, too, when Maria's illness and Sonic's death nearly causes him to go berserk.
Abraham has never been fond of the aliens on the ARK, but he was friends with Sonic, mainly because the hedgehog never quit trying. Abraham is also the only one permitted to keep his memories of Sonic, driving yet another wedge between him and the others.
Sonic wakes up on Christmas Island with the company of the chao and no memories to guide him.
