So I teamed up with writer whosdatboy to bring you guys this story. We decided to pursue this project because it's really fun and to develop our own writing.

We don't own Sonic the hedgehog or One punch man

Sonic and Tails were sitting at their usual hotdog stop that they enjoyed very much. Though the world was at peace now and Doctor Robotnic had been defeated Sonic could not but feel that he had become too powerful and that there was no one to stand in his way.

Sighhhhhhhhh - exhaled sonic as he chomped down on his third chili dog.

"What's wrong Sonic" said tails who was still on his first chili dog.

"I don't know there just isn't enough strong people left for me to defeat. When Robotnic was still around I could fight powerful foes right and left but know all I do is sit around waiting for when something somewhat interesting may come up."

"I don't know" said tails "maybe someone strong will come one day to fight you."

Just then a rift opened in the hot air in front of them a purple colored portal just came into being.

Though it looked dangerous sonic knew that an unlikely adversary and a powerful foe would be waiting on the other side. The urge was so strong that he even would give up his beloved chili dogs. Sonic then moved towards the portal.

"Where are you going!" gasped Tails

"I don't know" said Sonic "but this portal will take me to where I'm needed, where i can make a difference where I can finally find meaning to all of this power."

"But Sally and everyone else needs you Sonic" screamed tails as his last chance to get sonic to change his mind drifted away.

"No they don't Tails" said Sonic "they have you and a peaceful world and if it is in danger I will return but until then I must find a purpose for myself and my life. "Goodbye" said Tails "tell everyone I will be gone for a while and to not come after me. I have made up my mind."

"Goodbye" cried Tails as he saw his mentor his friend moving towards the portal for he knew there was nothing left for him to say.

Sonic then jumped into the mysterious portal which sucked him in with such force he thought he would be split in two as it shot him through space with every color of the rainbow flying past him. Finally he fell out the portal on what looked like the other side. He looked around and there in the clearing of the forest stood a peculiar man who was wearing a ninja suit and looked as if someone had punched him in the balls. Sonic ran as fast as he could not knowing if that was a friend or the powerful foe he sensed. He stopped himself right behind him and tapped on the broad shoulder of the skinny ninja and asked if he was okay.

"Just take deep slow breathes and the pain will go away" Sonic said.

"No" yelled the mysterious ninja as he slapped away Sonic's hand. " I'm Speed o sonic and i will not be pitied by someone weaker than me."

Inside Sonic grew both anger and an excitement to duel with a new unknown enemy

"Alright Speed o sonic I challenge you to a duel both for damaging my pride and for stealing my name. I'll test that speed of yours faker."

"Bring it on yelled" Speed o sonic.

To be continued…..
