Another day, another time at school. Everything seemed pretty normal for the students there, but it wasn't. In one of the bathrooms, there was some tremors going on and a large fish hand broke right through the floor and climbed out. People started running scared as the Shark came busting through the halls and people were running for their lives. Natsu and Lucy noticed him and knew this can't be good.

"Go! Run!" Natsu told Lucy and she went on ahead and was hoping for the best.

"You." Shark said as he was looking at Natsu. Now that he knows that Dragon-Man is Natsu, he's going to make sure Natsu doesn't get in his way anymore. "You've gotten in my way for the last time."

"You want me? Come and get me." Natsu dared. The Shark charged right at Natsu and Natsu charged at him. Shark swung one of his arms, but Natsu slid under it. Natsu jumped on his back and tried to hit him in the face, but Shark grabbed him and tossed him against the walls. Then, he tossed Natsu through the walls and in the science room. Shark came busting in and tried swinging one of his blades down, but Natsu rolled out of the way. Natsu tried to kick him in the stomach to push him back, but his steel-like body made it hard. "Nowhere to hide this time." He grabbed a hold of Natsu and slammed him against the floor and tossed him over to the wall. Shark spotted a couple chemicals and used his scientific mind. He took one chemical and crushed it into another with the mixture starting to smoke. When he tossed it over to Natsu, it exploded. "All the people that feel lost and weak, I can help them. I can save them. There's no reason to stop me." His response was a shoe tossed at him and Natsu jumped out with him dressed as Dragon-Man. He jumped right on Shark and tried to hold on as Shark tried to throw him off and fling himself around the halls.

"You're not thinking straight, doc." Natsu said as he was holding on. "Stop it. This isn't you. Let's talk about this."

"Let's not." Shark said as he grabbed him and tossed him to the floor. Shark tried swinging his fin-blades at him, but Natsu kept his distance from him.

"You don't want to talk? Fine by me." Natsu said as he jumped over him and kicked him in the back of the head. Shark tried back swinging his arm, but Natsu dodged the blade and grabbed his arm. "Don't…" He was thrown against one wall. "….make me…" Thrown against the other wall. "…have to…." Thrown against the ground. "….hurt you." Shark lifted him up and gave a strong hit that sent him flying through doors and into the next hall. Shark came marching after him.

"You're the only one that's going to get hurt for all your interference." Shark said. Natsu tried to kick him and hit his face, but Shark grabbed him again and slammed him against the windows. Shark was ready to kill him until Lucy came and slammed a trophy against him and got his attention. "Lucy!" He was surprised to see her and was about to attack her. Natsu raised his feet and kicked Shark right in the head and got free. Natsu went over to Lucy to help her. He took the trophy she used as a weapon and smashed it against the window with it breaking open. Natsu grabbed a hold of her and jumped out with her and undid his wings so they land gently with him placing her on the ground.

"Stay here." Natsu said and flew back to Shark. The two of them faced each other and heard police sirens on the way. "Sounds like someone has been a bad shark." The two of them continued to fight each other and smashed through the library where an old man was and listened to classics. He wasn't aware of what was going on behind him and as he left the room, Natsu was thrown against the bookshelf. When Natsu got back up, Shark was gone. Natsu went around the school to retrace his steps to find out what he's doing next. Natsu went over to the bathroom where he came from. "Sharky!" He called out as he jumped down and went after him. Police and doctors arrived and they were asking students questions and making sure no one was hurt. Lucy was worried about Natsu so she pulled out her phone to call him.

…..

The Sewers

Natsu treaded carefully as he traveled through the sewers again as he tried to find out where he went. He heard his phone go off and answered it.

"Yeah?" Natsu said.

"It's me. Where are you? Are you hurt?" Lucy asked.

"I'm fine." Natsu said. "I'm in the sewers tracking him down. I've got to stop him before someone gets hurt. Listen, you've worked with him, right?"

"Yeah." Lucy said.

"I need you to look up anything you can find." Natsu said. "We need an antidote to help him. He's bound to have something to reverse the effects and change him back to human."

"I think I already know what it is. I'll head over to the Tartaros Company and get to work on it." Lucy said. With a plan made, they hang up and Natsu got back to looking for Torafuzar. He walked through the sewers until he came across his lab.

"What is all this?" Natsu said as he looked around the place. Since the Shark is no longer acting or thinking like a wild beast, he was hoping to find answers to what he was planning here. Natsu looked on the computer and saw there was a video entry from the doctor in his human form. Natsu hit play to see if there was anything there.

"I've spent years studying and working at the Tartaros Company to improve humanity, but now I see it's pointless." Torafuzar said. "Human beings are weak, pathetic, and inferior creatures. So I say not to be human at all. I'll improve the human race and make all faster, stronger, and better than ever before." He looked on the computer and saw what he was planning. He's going to turn all humans to shark-like creatures just like himself and spread his serum all over the city. He also notice some paperwork and saw he needed one component and there was only one place he was going to get it.

"Tartaros!" Natsu said and Lucy is heading there right now and he knows what will happen if the Shark gets to her before he does.

…

The Police

The police has had enough of this madness and are planning to hunt both threats down. Captain Heartfilia was the one who was going to lead the charge with a helicopter running and getting ready to take off.

"Captain Heartfilia!" A policeman said.

"What?" Jude said.

"We have a confirm sighting, sir. The Shark was spotted by the Canal Street Station." The officer said.

"What about Dragon-Man?" Jude asked.

"He was in the high school, but no one knows which way he went or where he is now." The officer said.

"I want that dragon out of the air on off the streets." Jude said. He's had enough of Dragon-Man interfering and both of he and the Shark being so destructive. He got inside the helicopter and it started flying. Captain Heartfilia was going hunting and he was hunting a shark and a dragon.

…

The Shark

The Shark made it to the streets of the city and carried the compound he needed in a bag to infect the entire city, but he was no fool. He knows he's being hunted down. He only walked carefully because he just wanted them to come out and reveal themselves. He took a few steps and felt a bullet hit him. Many soldiers came out and starting firing a barrage of bullets at him. He tried to escape through the side, but there were soldiers over there too. They made sure he couldn't escape as bullets shot against him. He couldn't take much more and dropped to the ground. The soldiers advanced closer to him and held their fire to make sure he was confirmed dead. They poked around his body and it seemed like he really was dead.

"Is that the best you got?" Shark said. This shark just played possum. He pulled out a container that had some of the serum and released it as a purple cloud. The soldiers tried to fight him off, but they could barely keep themselves together from the cloud. Shark bashed his arm against one and sent him flying into a car. He grabbed another and smashed him against a light hanging above him. He gave one more a powerful punch and sent him flying into a taxi. Wasting enough of his time and already used part of his formula, he continued his destructive path and headed towards the Tartaros Company. As for the officers, the cloud was starting to affect and mutate all of them. They grew scales and gills with them turning purple. One took off his mask to breathe, but it wasn't enough and it revealed that his teeth became sharp. They are only the first of many. If Dragon-Man fails to stop the Shark, New York will turn into a shark pool.
