Chapter Text

The first chapter is just a sumary of the Au, you can find It too in Wattpad but in Spanish.

This is part of a series that Focus mostly on Shadows grow as a person, keeping him constant and In character because I miss his charactetion of SA2

If you read this is a Sonic and Shadow Roleswap Au but the diferences IS that Sonic is just a Guy and Shadow IS still proyect shadow.

This Au IS literally a What if Shadow was released earlier plus what If Sonic meet Elise first instead of Eggman

The reasons WHY this exist IS because I want to do a swap Au were the characters are still themselves but they adapt to the changes, how their relantionships can change or how they stay the same, they bring new unique dynamics, etc.

I'm mixing The Games with the Eclipse the darkling arc, Fleetway Iblis arc and the metarex arc plus remaking Shadow generations so It can fit my Au since the time Eater doesn't exist.

Also because no one has made an Au were Cosmo IS still Alive and is Knuckles sister.

So the roles are these:

Shadow -> Sonic (and viceversa)

Cream -> Tails (and viceversa but Tails is Evil)

Iblis -> Fleetway! Super Sonic/ STCO Iblis (I liked the Iblis adaptación of Fleetway than the Games so I Will use It but with changes here and there)

Whisper the world -> Eclipse the darkling
(Also Whisper IS dead and Tangle goes APE shit because of that)

The Avatar -> Infinite (this is a consequence of Sonic swap places with shadow, you Will see why)

Metal Sonic -> Shadow android (another consequence of Sonic swap places with shadow)

Cosmo IS still Alive because IS Mephiles Who dies while coping her form

The rest of the Cast still have their original roles

Any questions Will be answered in the coments

Chapter Text

In a gigant island in the night sky, there was a short, humanoid plant-like alien with pale peach skin, and metalic blue eyes with one long eyelash on each one.

This was Cosmo, the only survivor of her own species, she was sitting Next to the master Emerald looking at the stars while her Big brother was sleeping at her side.

When she first land in Shadow's world she was under Sonic and Amy's care, they were Also the first to question her arrival. She told them that she was looking for the "legendary hero that can use the Chaos Emeralds, Shadow the hedgehog".

Heh, It surprised and worried her how the legendary Hero was first trying to KILL her, Amy Rose and Sonic had to fight and Talk him down about her problems so shadow would give her a chance.

Later she had meet the only person she could relate to and later became her Big brother; Knuckles the equidna, their first meeting was in Emerald Hills he had saved her from a Big robot that was going to Smash her.

After a quick Talk with the Equidna, explaning to him how she wanted to find Shadow now that they were in good terms, apeared the person that would fuse with the Metarex in order to weak it so Super Shadow and Super Sonic could defeat It, Mephiles The Dark.

Poor Mephiles, she thought, begin one of the only inmortals on the world and Know that one day he could be Evil again... Must be so heartbreaking to him to see his friends die...

And still he gave his life for her happines, for Sonic--

Then she meet Doctor Robotnik (but Sonic always calls him Eggman or egghead, It was funny) and his Sidekick Doctor Power (or Tails, as she and Sonic call and refer him) and then they kidnapped her. Cosmo grabbed tightly one of her brother's gloves for comfort.

She was shaking at the memory, some nights she could relive the memory of begin placed on a table, completely strapped without being able to move or Scream, only the soft voice of Tails to calm her down while explaning that she had a chip on her brain, inconsciently making her a Spy for the metarex, before the pain-

Then she didn't remember nothing else, but she knew Knuckles and Rouge Team Up to rescue her, when they did she didn't hear them, only see them with her new Metalic blue eyes, completly scared.

She only knew the ending, Mephiles while disguising as her (he took form of her shadow aparently) to fuse with the Metarex so the day could be saved.

He lefted a Sonic in tears, a shaken Up Infinite and a silent Rouge.

Sometimes she feels It was unfair for her to be Alive, sometimes asking what she had done ...
