This is the second crossover I made, and it is inspired by Phantom Fan 21's Danny Phantom Hedgehog story. So I hope you like this.

Chapter 1: The Change

Ben Tennyson and Albedo are caught in an arm grapple on top of a bomb. The bomb released a flash of light instead of exploding.

"BEN!" yelled out Gwen and Kevin as they witness their team mate disappear.

(Mobian Forest)

Ben started to regain consciousness as he looks around.

"Am I in Heaven?" stuttered Ben as he scans his surroundings. He is in an uninhabited forest. He found a pond and ran to it to check on his condition. He looked at his reflection and saw that he is a green hedgehog, wearing the same clothes, but with black fingerless gloves, and black and green sneakers.

"What happened to me? I was human before I got here!" exclaimed Ben before he realized how he change.

'Of course, the bomb. I thought Albedo was trying to make people look like me, not a hedgehog' thought Ben before he looked at his left wrist.

'The Ultimatrix must have somehow interfered with the bomb, changing me into a hedgehog and teleporting me here' thought Ben. His thought got interrupted when he heard screaming.

"AAAHHHH!" screamed out from Ben's left.

"Hold on, I'm coming!" yelled out Ben as he ran into the direction where he heard the scream.

(Mobian Village)

"MWAHAHAHAHAHAHAHA!" laughed Eggman as he sees his foes trapped in a force field.

"You'll never get away with this, Eggman." said Sonic as he, Tails, Knuckles, Shadow, Amy, and Rouge remain trapped.

"Please, my force field can only be shut down from the outside, and we all know YOU ARE INSIDE!" laughed Eggman.

"Thanks for the tip." said an unknown voice. Everyone turned to the voice to see a green Hedgehog.

"Let me guess, another one of Sonic's friend? Well, it won't matter if you can't get pass my ROBOT ARMY!" yelled Eggman as his robots approach the Green Hedgehog.

"Well, I warned you." said the Green Hedgehog as he lifts his left sleeve to show the Ultimatrix. He scrolls through the list of aliens until he found Cannonbolt.

"IT'S HERO TIME!" yelled Ben as he slams the Ultimatrix, and a flash of light occurred. Everyone shielded their eyes to prevent themselvesfrom getting blind. As soon as the light died down, Ben appeared in a new form. He didn't turn into Cannonbolt, but his transformation has some similarities. His green fur changed to white, and his fingers turned into black claws along with his feet. He has yellow shoulder, elbow, and knee pads. His back has a yellow shell. He is not wearing clothes. He has a black stripe from between his legs to below the neck. His lips are black. He grew small fangs. Another black stripe appeared above his eyes up to his mid quills.

"Cannonbolt" yelled out the white hedgehog. Everyone stared shocked at his transformation. He looked at himself, either surprised or disappointed.

'I'm not Cannonbolt, I'm still a hedgehog. Wait a minute, I have some similarities to Cannonbolt. The bomb must've changed the Ultimatrix as well, allowing me to merge my new DNA with other DNA from the Codon Stream.' thought Cannonbolt.

"It doesn't matter what you are. ROBOTS, ATTACK!" ordered Eggman. The robot army charged at Cannonbolt. He curved into a ball and began to spin dash at the robot army. The robots started shooting lasers at him, but thanks to his ball armor, the shots just bounce off him. He struck 10 robots like a bowling ball.

"STRIKE!" joked Cannonbolt. He kept striking all of the robots on their heads to knock them out. All the robots are on the ground, headless. The only robot left is the one Eggman is steering on top of the force field.

"Wha-What are you?" stuttered Eggman as Cannonbolt approaches him.

"I'm a SUPERHERO!" smirked Cannonbolt as he charges at Eggman. Eggman ejected his robot before it got hit and the force field disabled.

"I'LL BE BAAAAAAACK!" echoed Eggman as he flies away. Cannonbolt changed back to normal before falling unconscious.

"Is he okay?" asked Tails. Rouge went to check his pulse before looking at his face.

'He's cute' thought Rouge as she scans the Green Hedgehog.

"Uh, Rouge, are you okay?" asked Amy. Rouge inwardly shook her head before answering.

"Yeah, and so is he. He must've gotten tired from all that spin dashing." stated Rouge.

"Don't blame him. I would get tired too if I beat 100 robots with spin dashing only." stated Sonic.

"I'll carry him to our base. I've got some questioning for him." said Shadow as he cautiously carries an arm of the Green Hedgehog.

"I'll help carry him, too." volunteered Rouge as she went to carry the other side. They began to walk to the base. What they don't know is that a pair of red eyes was watching them.

All right. That's it for the first chapter. Who was the red-eyed person that was watching them. How will Ben react when he wakes up. And is there going to be a love interest from Rouge to Ben. Find out next time on Hedgehog 10.
