My name is Speed-O-Sound Sonic! I am the strongest ninja in the world! I came from a ninja village where I had perfected my moves to the point. Though there is one person I currently can't beat, even when I go all out in my Mach speeds and full into all my ninja tricks. His name is Saitama, my rival of whom I shall defeat! I found a little piglet one day. I saved it from a snake and named it Ino. It's followed me while I trained, but now I'm back on my own path.
