At Foot Headquarters, in a room, Oroku Saki was sitting near a table.

He smirks. "Why don't you quit playing games,"

Slashuur teleports above him from the ceiling and floats down and lands in front of Saki.

"Your skill hasn't dulled at all."

"Your task can't wait no longer. Destroy the turtles." Saki orders. "I also want you to capture this girl as well. Bring her to me once you've the job." Saki hands Slashuur a picture Yuuki and he takes it.

"What's so important about this girl?" Slashuur asked.

"She is the daughter of my rival, and I personally want to destroy her myself." Saki smirks.

As Slashuur turns to leave, Saki speaks. "By the way, have you found that which you seek?"

"No, but for some reason when I seen those turtles, I feel as though I could almost recall what I've lost. But, that's wishful thinking, until we meet again." Slashuur said as he walks away, vanishing from the dark room.

Saki sneers.

"Living without a memory must be difficult."

In the sewers, Leo, Mikey, Raph, Mona, Venus and Donnie were walking around while Donnie held a device, tracking something.

"Hey, can't we head back yet? This fresh sewer scent is really starting to wear thin," Mikey complains.

"We're not far. The localized electromagnetic anomaly is right around here. Something's getting ready to happen and it's not going to be good," Donnie explained.

"I bet it's the Foot again. It sounds like the work of Leo's lady friend, Karai," Raph said.

"Come on, Raph, we can't be sure. Karai is working to bring order to New York, I want to trust her," Leo replied.

"Yeah, but can we afford to? In the end, you know she's with the Foot," Raph argues.

"What's that alarm set for? I just had lunch and I had my afternoon snack, it's a bit early for dinner," Mikey asked and Raph smacks him on the head.

"Before Stockman took that fall, he should've given your head a tune up. So you can think about things other than food," Raph said.

The group stops and sees a portal in front of them.

"This is it. I'm getting strange readings from an electromagnetic field inside this hole." Donnie informs.

"Let's get going, and be careful there's no telling what could happen," Leo said.

Mikey steps up to the portal. "Hello, anybody home?" He asked as he walks through it. Then Donnie, Leo, Raph, Mona, and Venus follow in after him.

Rain was pouring down hard, over a remains of what appeared to be a city in ruins, it almost looked like New York City.

As they stepped out, everyone gasps in shock at what they see in front of them.

Mikey stomach growls. "Seriously, at a time like this, my stomach has a mind of it's own. Listen up tummy, this isn't the time," Mikey said as he rubs his stomach. Raph shakes his head and face palms.

"Unless my eyes are deceiving me, I'd say we're in New York. What the heck happened here?" Donnie asked.

"Welcome, turtles," A voice calls out. "Long time no see." Everyone turns around to see Slashuur behind them.

"Slashuur!" The brothers shouted.

Slashuur laughs. "I don't need all of you to tell me my own name."

Then the group hears someone struggling and looks behind Slashuur to see Yuuki, and tied up in ropes. Leo gasps. But, she was in her room when he dropped her off. Slashuur must've got her once he left. Leo clenches his fists, mentally kicking himself for not sensing him when he left her. And now, Yuuki was in danger again. Because of him...

"Guys, a little help here! Who the heck is this guy?!" Yuuki shouted. "What did you guys get yourselves involved in?!"

"Slashuur! If you harmed her in anyway, I swear you'll regret it!" Leo growls.

Slashuur laughs. He picks Yuuki up by her ropes. "Relax, I haven't done anything to her,...yet." He taunts. Then he throws her to the ground.

"More importantly, tell me what you think of this planet?" He asked.

"What we think is, it's a wasteland. If you know what happened here, clue us in on it," Raph growls.

"Hold on, Raph," Donnie said as he stops Raph from charging. Then he turns to Slashuur. "My guess is that this is New York, just not the New York we know. Probably an alternative reality New York, am I right?"

Slashuur starts to advance closer the group. Donnie and Raph held Venus and Mona behind them and got into a fighting stance as well as Leo and Mikey.

"A clever attempt, but you're off. It's your New York, it's just not the New York at the time you knew." Slashuur explained. "I went to the trouble of bringing you all here so I could show you this future world,"

The group stared in shock. This was the future?!

"This...is New York in the future?! No way! What happened?!" Leo exclaimed.

"A battle, many battle such as this have existed from the distant past and lasts far into the future. The world you see here, is one potential future should things continue as they are," Slashuur said.

"But you're a mercenary, right? If you hate war so much, you sure picked the wrong job," Mikey retorts.

"You think I became a mercenary for the love of war? Only by giving ones pure strength against another's, do true champions arise, I seek such champion. Yes, more like Hamato Yoshi,"

"How do you know Master Yoshi?!" Mikey shouted.

"Save that question for later. To begin, you must all show me your true strength. If you cannot defeat me here, you'll never return to the world you knew,"

A scythe appears in Slashuur's hands and he swings it. An orange platform appeared underneath everyone and it starts to float going higher into the sky.

Leo turns to Yuuki. "Just sit tight. This won't take long." He tells her.

"Like I've got a choice?" Yuuki asked as she struggles to break free from her ropes.

Raph and Donnie turns to Venus and Mona. "You girls, stay back and leave the fighting to us." Raph tells them.

Venus tries to speak "But -" Donnie interrupts her "Trust us, you don't know what you're dealing with. "

"And you do?" Venus replied , sarcastically.

"Seriously, this guy's got some weird power. The first time we've fought, he almost knocked us all flat on our shells! This is no joke!" Mikey exclaims.

Venus turns to Donnie. "Okay, but you better win." She answered.

"We plan to." Raph said as he draws his sais. The other three brothers draw their weapons as well. Venus and Mona step back and the brothers and Slashuur face each other. Neither of them made a move, waiting to see who will strike first.

Then Slashuur charges and the brothers charge as well. Slashuur swings his scythe and Mikey ducks and jumps out of the way. Donnie jumps bring down his staff but Slashuur grabs it and tosses Donnie. He flies in the air and lands on the platform, sliding off, and was now dangling off the edge.

"Donatello!" Venus shouted, worried.

Raph growls and rushes towards Slashuur trying to stab him with his sais. Slashuur teleports and appears behind him and kicks Raph, knocking him down. Slashuur swings his scythe above his head, getting ready to bring it down on the turtle. There was a clash against it as swords blocked the blow.

Leo and Slashuur struggles against each other, trying to push each other back.

"Why are you doing this?!" Leo demanded.

Slashuur only laughs.

Then Leo kicks at him and Slashuur dodges and flips back and lands on his feet. Mikey helps Donnie up and the two run towards the other two brothers to regroup. They were panting heavily and sweat began to drop from their face.

"This is getting nowhere, Leo!" Raph growls, irritated.

"Yeah, how are we supposed to beat him?!" Mikey exclaims.

"He's just toying with us." Donnie gritted his teeth.

"Then let's play his game." Leo said as he grips his swords. The three brothers looks at him confused. Leo turns to them and starts whispering and planning.

"I'm starting to grow bored with this." Slashuur said. "What are you four whispering about?! Just admit defeat already! You four will only cause the world harm."

"You're wrong!" Yuuki shouted. "Without them, I wouldn't be were i am today!"

"They saved us!" Venus exclaimed.

"It's just the inevitable. The end of the world will come and when it does it will be by these four doing! Knowing that, you will still be with them."

"Yes." Yuuki answered, simply as she glared at him.

"Same goes for me! " Venus replied and Mona nods.

"Then you're fools." Slashuur laughs.

Suddenly, Slashuur was knocked back as Mikey hits him with his nunchucks. Mikey laughs. "And you're a fool for letting your guard down!" He taunts.

Leo jumps in and slashes at Slashuur with his swords. Then Raph swipes at the armor with his sais. Slashuur's armor begins to spark. Donnie swings his bo staff and knocks Slashuur down.

Slashuur falls to his knees as his armor sparks.

Leo runs over to Yuuki and slices the ropes. She throws her arms around him. "You did it! You guys totally kicked his butt!" Then she turns to hug Mikey as well.

Venus and Mona embraced Donnie and Raph. As the group cheered, they hear laughing behind them. They turned to see Slashuur, now standing up.

"So, I'm beaten once again by Hamato Yoshi," He pants.

"No, the four of us were only able to beat you by combining our strengths," Leo said. "I'd like to know one thing. How did you know Master Yoshi?"

"I once had the opportunity to face him in a match," Slashuur said.

"Wait, you fought my father?" Yuuki asked.

"You're his daughter?" Slashuur asked, shocked.

Leo steps up to Yuuki and places his arm around her shoulder. "Yes, she is Yoshi's daughter, but we never studied directly under Master Yoshi. Our master's name is Splinter," Leo explained.

"He's a rat, but seriously skilled! I guess he's about the most skillful ninja in the universe," Mikey replied.

Slashuur thinks for a moment until he realizes. "Splinter, a rat? Ah, you must mean that pet of Yoshi's he loved so much. Quite small for a master, though," He laughs a bit.

"How is Hamato Yoshi these days?"

"The great Master Yoshi perished after falling into a cruel and cowardly trap set by an evil one called Shredder," Donnie tells him.

Slashuur's eyes widen in shock. "WHAT?!" He exclaimed in shock and anger. "The Shredder?! That fiend never spoke a word of this!"

Suddenly, a vivid memory appears in his head. He groans, holding his head in pain.

"Hey, did he get a bad kick under the belt or something?" Mikey asked as he turns to the group.

"It's all coming back. How can this be..." Slashuur growls. "Shredder, he played me like a pipe!"

"You mean, you know the Shredder? And what is it that you remembered?" Leo questioned.

"Shredder is an old acquaintance and my current employer. Once long ago, I sustained mortal wounds from that day, inexplicably, I gained the the ability to move freely through space and time. But, this came at the cost of my previous memory. But, now I remember it all. His true identity was that of an ruthless criminal in my hometown. One day he sacked the town stealing and destroying everything. I made it out somehow, but my family and friends,"

"That's...that's awful. But, wait...you said your hometown? But you couldn't mean that you're an Utrom would you?" Donnie asked.

Slashuur laughs. "Yes, I am an Utrom." The stomach plate from his armor opens up revealing a Utrom with a scar across his face. "What a surprise, you actually know of us, the Utroms?"

"Yes. Once an Utrom known as Mortu came to our rescue," Leo answered.

Slashuur ponders for a moment thinking of the name. "Mortu...yes, I remember him. We know each other well. Shredder will be after him for certain. Is he safe?"

"Right now he's back on his home planet. He's an honored ally we can always count on," Mikey said.

"Fine then, I would like to hear more, but I must get going. I'm grateful to you all. We've lost all things dear to us by Shredder's hand. I'm sure one day I'll be able to pay you back," Slashuur walks away.

"Wait! There's so much more I want to ask. We'll meet again right? And what about the contract out on us?" Leo asked.

"I will be back and remember one thing, I never take a job when all of the facts aren't fully disclosed."

Slashuur opens a portal and everyone walks through it ending up back in the sewers.
