Sonic left Robotropolis at the age of eleven, going after Robotnik. After five years can he go back his kingdom? A story I uploaded on to FanFiction.net which became popular.

Same storyline as Sonic Underground except for one detail. They're not triplets, they're quadruplets! Dr. Robotnik has captured their youngest sister, Ambrosia, Amber for short. Using her as bait, he informs them that at the end of the week, he'll Robotisize her. Terrified at the prospect of losing their sister before they've even found their mother; the three siblings come up with a rescue plan...

After being missing for about 4 years Sonia, Manic, and Queen Aleena have finally located their missing family member. Sonic the Hedgehog who disappeared after Robotnick escaped from the Sonic Underground base. Sonic has been chasing the evil man for years now having to leave his family behind and making a new one. What will happen when the three hedgehogs that have been missing from the blue hedgehog's life finally reappear?

Sonic never told Shadow, Tails, and his friends about his life about Sonic Underground, or the fact he was a prince, searching for his mother. When Dr. Rototnik threatens Mobius, he knew that he has to reunite with his siblings and help them find their mother, Queen Aleena along with his friends, making the Prophecy coming true.

My twist on a Sonic X/Underground fanfic! There's no Chris, and it's completely original from where I make friendships. It's a bit AU. Includes some OC's. Orrrrr. Sonic disappears, time goes by, Sonia and Manic search for their brother who's already found a missing piece of their family. The Oracle keeps watch of the hedgehogs, Sonic's friends don't know what's going on- and a new prophecy forms.

Sonic's past is a twisted one that he's been running from. He's been running from it for who knows long? His friends know nothing about the blue hedgehog's past. Not even Tails himself. But when Sonic's last catches up with him what will he do?

Sonic the hedgehog isn't from this world, but from another, driven by war his world is chaotic and falling apart, but yet he is here, trapped, unable to find away home but what happens when his enemy from his world tries to take over the one he is in now? and what happens if the resistance is here as well?

From the very talented @TheGeekyGamerReborn I decided to put some left out characters and add my character to it.

This is gonna be a long one. The prophecy is nearing, but Robotnik is drawing out his war efforts, The Great War, is ending...

Sonic dug through a box of his old things. "Why are we selling our old stuff again Tails?" He asked as he pulled out some old sneakers "It's either this or you get a job." "Okay geez..." Sonic continued to dig through the box "No way..." He pulled an old medallion out of the box, it was shaped like a guitar "I haven't seen this thing in years..." "Seen what Sonic?" Tails asked from the other side of the room as the two tailed fox set down one of Sonics old pairs of sneakers "It's a long story, a story of a past I tried to leave behind..." Sonic replied, thinking about the horrible things that had happened in the past To be clear, unless it's stated by me in an author's note, or the star I use to sign my drawings or painting is on the art, I probably found it on Pinterest and in no way mean to take credit for someone else's art.
