Hi everyone! Well… I have something in my mind about Vert and his team being mutated and turn into mutant animals from TMNT 2012. It would be cool and awesome as they have the ability to morph between human and mutant form. Hope you enjoy this story. Please review. :)

Chapter 1

Vert and his team were in the Factory Zone to investigate. About few minutes ago, Sage told the team about a chemical called "Mutagen Ooze" or "Ooze". The chemicals are very dangerous, Sage told the team about the Mutagen Ooze that it can mutate anything including humans with a mix of their DNA.

"Alright guys… Remember what Sage told about the Mutagen Ooze." Vert said through the com-link, "Yeah. We know," Spinner said, "Those Ooze can mutate anything alright. If we get exposed by them… something might happen." Sherman said, "Yes. And very unstable." Tezz added, "I wonder if we get mutate by those things," Zoom asked.

"If we are mutate… there's no way to change back," Agura said, "Oh," Zoom muttered, "I wonder why Sage want us to investigate this place?" Spinner asked, "I dunno." Vert replied. Agura suddenly felt something, "Hold up," she said as the team halt, "What's wrong, Agura?" Vert asked her, "I think we're being watched…" The hunter said. All of the sudden a Venikus drops down from the ceiling and landed on top of the Tangler. Agura exclaimed in surprise by the sudden ambush. Zoom was about to help her when he saw the Vylirex heading towards him. Zoom quickly missed and chase after Kytren, "Take all of the Mutagen Ooze now!" Krytus ordered his team.

"Don't let Krytus and his team take the Mutagen Ooze, team!" Vert said, "Got it, Vert!" The Cortez bros said as the Buster Tank rammed the Synataur. Vert chase rammed the side of the Syfurious and that made Krytus growl and glared at Vert. He morph out his vehicle and turn his hand into a sword. Vert got out his Saber and took out his own sword. Then they clash each other, "Why do you want the Mutagen Ooze, Krytus?" Vert asked, swung his sword at Krytus but missed, "I'll use it to mutate all over the Multiverse. Including Earth where Sage is," he said, "Not gonna happen!" Vert shouted as he swung his sword, Krytus block his sword.

Krytus looked at the tank that fills with Mutagen. Then he smile evilly as he had an idea. He run towards the platform and Vert chase after him. As Krytus is on the platform right below the Mutagen tank, Vert was too, on the platform. "I won't let you mutate the Multiverse and the Earth," he said, Krytus laugh. "Really? Then let's you can save the Multiverse and the Earth," he taunted at Vert and that made him mad. Vert charge at Krytus and swung his sword but Krytus block the blow and kicked Vert causing him to lost his balance. He suddenly falls and dived into the Mutagen.

Krytus looked down from the platform with an evil smirk watching Vert sinking into the Mutagen tank. "RS5 retreat to the portal!" He ordered his team as jump down from the platform before morph inside his vehicle. The RS5 races towards their portal leaving the BF5 in confusion, "Okay… what just happen?" Zoom asked, "I dunno. Hey, where's Vert?" Agura asked.

Out of the corner of Tezz's eyes. He saw something climb out from the Mutagen tank, "Everyone… I think we have a problem," he said, "What problem," Sherman asked confused and Tezz pointed at the Mutagen tank, the team look of what Tezz is pointing at. The team are in shock of what they saw. A humanoid-like saber-tooth tiger about 9 feet tall of its height. Its fur is all dark brown and very thick, long tail, sharp teeth with two large fangs in front of its mouth, sharp claws and light green eyes. Also wearing its red shock suit. Then it jump down and landed on the ground and roars throughout the factory, Spinner screams in fear, "W-What is that thing?!"

"It looks like a version of a saber-tooth tiger," Sherman said and Zoom notice the beast's shock suit and realized in shock, "Guys… I think that thing is… Vert," he muttered, "Zoom, are you out of your mind," Spinner exclaimed, "Look closely!" Zoom said.

The team look very closely at the beast and noticed the red shock suit, "Is that… really Vert?" Agura asked as she stares at that humanoid saber-tooth tiger. The beast suddenly speaks which shock the team as they recognized that voice, "What… happen… to… me…?" Vert's voice asked, "Zoom, you're right. It is Vert." Tezz said still shock, "What happen to him?" Agura asked, "He's been exposed by the Mutagen Ooze and mutated. I don't think Vert can't control his mutation or himself. And he doesn't even know himself after he's been mutated. Even us," Sherman said.

Agura got out her Tangler and walk towards the mutant Vert, "Agura, stay away from him." Tezz warned her but she ignore him as she was now in front just inches away from him, "Vert?" She asked Vert respond with a growl and glares at her, "Vert. It's me, Agura. You're the leader of the BF5. Don't forget of who you are and also don't forget us," she remind and Vert instantly know who he is and who his team is, "Agura?" He said by her name. "Yes. You still remember right? Now c'mon. Let's find a way to change you back." Agura said but to her surprise Vert morph back to his human form.

"What?" Agura asked confused and surprise, "He… He change back," Spinner said with wide-eyed, "But how?" Sherman asked very confused, "I… I have no idea of how Vert change back his normal form," Tezz said. Agura slowly walk towards Vert, "Vert? Are you okay?" Vert look up at her with still mutant light green eyes before his eyes went back to blue, "Yeah… I think," Vert said feeling dizzy after mutated.

"C'mon. Let's head back to Earth." Agura said. Before they go Tezz brings 7 Mutagen Oozes to examine them. Then the BF5 straight back to Earth as they went through the StormShock portal.

Well, that's it. I hope you like this story. Please review.
