The Ultimate Lifeforms by HannaCleveland

It's been a week since Solaris was defeated. Sonic and Shadow are 'brothers' now and Shadow has moved in with him and Tails. In his quest to uncover the rest of his past, Shadow is forced to work for Eggman to obtain the pages to Professor Gerald Robotnik's journal from him. Receiving a few of the pages, Shadow makes a shocking discovery connecting him and Sonic. It seemed they were even closer and more similar than previously thought. This is a SEQUEL. If you haven't read the first story, Return to Robotropolis, I suggest you do. I originally posted this story on FanFiction.Net.

A Dazzling Destiny (Sonic Underground x Reader) by ThaliaGabbyP

Unfinished plots have left fans desperate long enough. After all they've been through, it's about time Sonic and sibs finally find their mom and restore Mobotropolis to it's former glory. However, there is another piece of the prophesy that has yet to be revealed and without it, Robotnik will rule forever. The fate of the world and everything in it rests in the unknowing hands of Y/N L/N.

Losing a dare to Sonic, Shadow is forced to be shown what fun is by Sonic. The blue hero of Möbius takes his rival to meet his family in the castle and they take a vacation there. Sonic had already loved Shadow and Shadow soon learns he also loved the blue hero back in a matter of days.

(note I don't own Sonic Skyline or Sonic itself. I just thought that Skyline looked cool and the comic was pretty cool so I wanted to make my own spin in the story, so please enjoy) Sonic never thought he'll ever go on adventures and travel to other sky islands, but that all changed when he met Dr.Eggman, a human from the ground who wants to help Mobius be a better place. With the help of Eggman and his allies in the Skyline corporation, Sonic and his friends are going to travel the sky islands and fought evil robots, and maybe even save the world. (All rights go to Drawloverlala and Sega) #1 in Sonic Skyline!!!!
