SC fallen (sansAU)

So this is supposed to be a Undertale I forgot what it was called I think it was like a sans au or something but this is a sonic version (sonic in the background is the normal sans and cream is supposed to be frisk or something) . sonic(sans):you already know his personality . cream/Y/N(if you want):in the background she lost a bit of her soul cause...youll know if you read the story ... . . . STORY:cream/Y/N was controlled by chara/surge(chara/surge is made up by me) and the au sonic (and other sonic character as au sans) had to fight you and was able to save you now you wanted to fight chara alone and sonic was worried ... . . . . . (ANYWAY THAT'S IT DON'T READ SOME PART IF YOU DON'T LIKE LONG STUFF!!!)
