Naruto: The Yellow Flash's Second Coming by SakkaKun987 reviews
To keep it simple, I'm keeping it strictly in the Naruto-Verse. However, I will be using Sonic implications. I thought what better way to do it, than use some Sonic Unleashed references, as well as Sonic SFM Fighting references to define Naruto and help guide the story along. This will be a Naruto who was given the chance to prove himself before he began acting "naively".
