Disclaimer: I do not own Harry Potter or Teenage Mutant Ninja Turtles.
Things have been tense since Harry's disappearance. The family has been working tirelessly to find their lost member but with Donatello still working on creating more retro mutagen, and the fact that Harry knew how to cover his tracks well, it didn't look like they'd be getting him back anytime soon.
In the meanwhile, Karai still racked with guilt over Harry's mutation has been taking a lot of heat from Raphael lately. Though she suspected Donatello and Michelangelo were over a similar mindset, they kept busy with the purple clad turtle working on a cure while the orange turtle kept himself distracted by any means possible.
The only ones in the lair that weren't aggressive towards her – passively or otherwise were Leo, Hedwig, and her father. Still the atmosphere was too stifling for the kunoichi, which saw her head to the surface.
As it turns out her little reprieve didn't last long as she stumbled across a trio of Kraang droids. The aliens had just managed to get their tentacles on some plutonium. Since she was trying to be one of the good guys now, Karai couldn't very well let that go.
Kraang: "Kraang must evade she who is pursuing Kraang" said the aliens, as the former Foot kunoichi chased them across rooftops.
"Yeah, good luck with that" said Karai taunted, evading laser fire as she worked to catch up to the aliens.
Determined not to let Karai catch them, the Kraang droids made a jump for a nearby fire escape, with one taking up a position to lay down cover fire as the other two started to descend down to the alley below.
Not about to let the aliens get away with such dangerous cargo, Karai dived forward, twisting her body around laser fire, bearing down on the Kraang with her with tantō slicing it from the droid's hip to sternum.
One down Karai smirked, jumping off the fire escape to continue her pursuit. But when she reached the alley all she found were the broken remains of Kraang droids and the now empty case of plutonium. Great so someone's going around smashing Kraang and stealing plutonium. Just super, I just can't wait until Raphael tells me how I screwed up.
Upon her return to the lair, Karai explained what happened and as expected Raphael didn't disappoint in his quick criticism of her.
"So basically, you screwed up" said Raph.
"Hey I didn't screw up, anything!" Karai argued. "Someone else went after The Kraang and it didn't look like the Foot's handiwork. It didn't look like Jones' work either so it's obviously a new player."
"So what's the problem?" said Mikey. "Just means we've got more time to look for Harry."
"The problem, Mikey is whoever took down The Kraang took the plutonium they stole." Said Raph. "There's no point in finding Harry, if whoever it was ends up blowing up the city."
"We better blanket the area" said Leo, taking command. "Donnie and Mikey, you take the Rooftops. Raph, you've got the alleyways. Karai and I'll cover the sewers. We'll meet back at the lair at midnight."
"You think we've been too hard on, Karai?" asked Mikey, as he and Donnie moved across the rooftops.
"I don't know" said Donnie. "Maybe."
Logically, Donnie knew it wasn't Karai's fault that Harry was mutated. There was no way anyone could've predicted him forcing a teleport, nor that it would backfire like it did. Still didn't make it any easier to deal with the absence of their youngest brother.
"Woah dude" Mikey gasped, drawing Donatello from his thoughts. "Check it out Don."
On a nearby rooftop they found the scattered remains of destroyed Kraang droids. Investigating the scene, Donnie identified carbon scorching, a clear sign of plasma weaponry. Whoever was going after The Kraang had technology just as advanced as the aliens.
"Just give it time" said Leo, as he and Karai moved through the sewers. "I'm sure the guys will come around."
"I guess Mikey and Donnie aren't that bad" said Karai. "I just wish Raph would get off my back. I feel bad enough about what happened."
"I know you do…hey I think I've got something." Switching on his flashlight, Leo exposed several broken Kraang droids, left scattered around the sewer tunnel. "Wow that's a lot of Kraang."
Continuing further into the tunnel they found dozens of more broken remains, ending in a giant pile of Kraang droid heads.
"Whoever did this didn't just destroy The Kraang-they annihilated them" Leo commented.
"Hey, Leo check this out" said Karai, holding out what looked like a broken spike of some sort.
Leo's eyes widened in horror as he recognized the barb "Oh no."
Raphael had been checking out the alleyways as ordered, when he stumbled upon The Kraang loading up a van. Before he could call it into the others an old friend decided to drop in for a visit.
"Spike" Raph gasped, as his former pet turtle landed in front of him.
"It's Slash now remember" he reminded his former owner. "How you doing, Raphael – miss me?"
"What're you doing here, Slash?"
"I've got a new partner now and we're taking care of The Kraang."
Right on cue a large explosion came from the alley, flipping over the alien's van. The night's craziness took a big leap as the Newtralizer of all people dropped on top of the turned over vehicle and started firing on the Kraang droids crying "Destruction to The Kraang!"
Raph couldn't believe it. Slash had teamed up with the alien psychopath. "What're you doing Slash?!"
"What you couldn't" said Slash, brandishing his mace. "Keep out of the way!"
Raph watched as Slash rushed into battle, smashing Kraang droids to pieces with his mace, while the Newtralizer's numerous weapons provided long rang support. For a minute Raph was tempted just to leave them alone, that is until he noticed Newtralizer break into the Kraang van.
Inside the van the Newtralizer picked up a bit of tech, mounting it to his wrist before powering it with the stolen plutonium.
"Slash, we have what he came for!" Newtralizer called, tossing a second wrist band to his partner.
Slash caught and curiously examined the piece of technology, when Raph deciding he wasn't about to let them run off with stolen Kraang tech, charged in. Slash swung his mace down on the advancing turtle, but Raph quickly rolled underneath his swing.
Slash tried go for another attack but the faster Raph jumped onto the larger turtle's shell, knocking him off balance, as he used it as a springboard. With his former friend's footing compromised, Raph went on the offensive, his sais at the ready. But Slash managed to recover in time to bring his mace up to block the red turtles sais, the larger turtle then countered with a powerful right hook to the jaw, knocking Raph to the ground.
"We're done here, Slash" said the Newtralizer, activating the stolen device and teleporting away. Slash followed soon after.
"Aww sewer apples" Raph cursed, painfully reminded of his frequently teleporting brother.
Returning to the lair, Raph and the others gathered around the kitchen table to discuss the new dream team of Slash and Newtralizer.
"What and the great Raphael couldn't stop them" said Karai, obviously getting payback for the red turtle's earlier comment.
Raph was about to snap at the kunoichi when Leo decided to put an end to it.
"We need to focus people! We've got two crazy mutants out there blowing up the streets!"
"Maybe we should shadow The Kraang until they show up" Raph suggested, deciding they had more important things to worry about.
"Easy" said Donnie, typing on his laptop. "Since Slash and Newtralizer are using plutonium to power their teleportation we can look for traces of residual radiation."
It was a program that Donnie had originally been working on to track down Harry. They just needed their mutated brother to start teleporting again but this made for a good test run. At least it was until Pac man suddenly showed up and started eating the red dots representing the radiation trail.
"Mikey!" Donnie snapped. "Would you stop eating the Kraang locations!"
Strange as it was Mikey had plugged his joystick into Donatello's laptop turning it into the classic arcade game.
"Hold on, D, I've almost got the high score" said Mikey. "Ugh, Donnie" he groaned, as his brother ripped the control out of his hands.
Operating out of an old warehouse, a small group of Kraang droids were standing guard. The aliens were on high alert after the recent trouble Slash and the Newtralizer had caused them. Too bad for them they weren't ready for the two of them to teleport straight into the building.
The Kraang didn't even have time to sound the alarms before Slash and Newtralizer took them out.
"Let's do this" said Slash, eager for a fight.
"First we find communications" said Newtralizer. "Then we blow this place."
"Blow this place?!" Slash didn't like the sound of that. "Too dangerous. What about the humans out on the street?"
"Remember the day we met Slash?" said the alien lizard "The vow we made."
Shortly after his defeat at the hands of Raphael – Slash had found himself a prisoner of The Kraang. Bound and shackled he was brought to one of their hidden bases. Slash wasn't expecting to make it out of there alive but then the Newtralizer arrived. He defeated the Kraang guards and freed Slash. After that they had teamed up, vowing to destroy The Kraang at any cost.
"At any cost" Newtralizer reminded Slash. "Right brother?"
Remembering his vow, Slash agreed and the pair went off to make a sweep of the rest of the building.
It hadn't taken long for them make quick work of the remaining Kraang forces in the building and Newtralizer was pleased to find a communication orb just waiting for the taking. Using his own alien technology, Newtralizer hacked into the orb and managed to pick up on some interesting information.
"Want to let me in on the plan" said Slash, as he couldn't understand the alien language and his partner wasn't feeling in a sharing mood.
"In time" Newtralizer promised, though a part of himself was now concerned about Slash's commitment to their mission.
As they focused on the communication orb, they failed to notice Karai and the Turtles drop down into the building. The ninjas quickly took their positons, staying out of sight as they waited for the right moment to strike.
"Woah, it's the Newtralizer" said Mikey. "I totally named that guy."
"Actually I named him" Donnie reminded him, much to Mikey's annoyance as he didn't like anyone intruding on his naming rights.
"Alright, guys" Leo spoke up, getting them to focus. "We hit them hard and fast."
"Don't look now but it looks like your girlfriend's one step ahead of you" said Raph, pointing to the rafters where they could see Karai silently approaching their targets.
Karai's eyes narrowed as she focused on Slash and Newtralizer, confident she could take one of them out with her surprise attack. Despite her feelings towards him, she had grown up with Shredder and he wasn't one to advocate teamwork. So it never even occurred to the kunoichi to wait for the Turtles' backup as she dived down on her target.
Choosing Newtralizer as her target, Karai brought her tantō down on the alien lizard. But while the alien lizard didn't have time to react, Slash did. The large mutant turtle proved far faster than Karai had expected, intercepting her attempt at a sneak attack with his mace, before grabbing her by the arm and throwing her flying into the approaching Leonardo.
With their cover blown the rest of the Turtles charged into battle. Mikey with his nunchucks at the ready went after Newtralizer but the alien lizard was ready this time, and savagely whipped his tail at the orange turtle, knocking him away.
Newtralizer was then forced on the defensive as Raphael came in, attempting to stab the alien lizard with his sais. But the Newtralizer proved too quick for the red clad turtle, as the alien kept just out of the range of Raph's weapons. But it turned out the alien was simply waiting for the right moment; sidestepping Raph's latest attempt to land a hit, the alien grabbed his outstretched arm and tossed him over his shoulder, down onto the lower level of the warehouse.
Eager to deal with his former friend, Slash followed after the dazed Raph, planning to use the opportunity to deal some serious damage. Lucky for Raph, his former pet wasn't the only one to notice his fall, as Donnie quickly jumped onto Slash's back, attempting to force him away from his brother.
But Slash's greater size and strength proved too much for the brainy turtle, and was easily tossed to the ground.
"Eager for another beat down, Donatello" said Slash, about to bring his mace down on the purple turtle's head. But before he could, Slash was forced to abandon his attack when he felt a shuriken dig into his shoulder.
The mutant looked over to see the culprit was none other than a recovered Karai, who scowled at the powerful mutant.
"Get away from him" she demanded, charging forward. But Slash was ready for her, bringing his mace up in time to block the kunoichi's blade. The rouge mutant turtle then grabbed Karai around the middle, forcing a scream out of her as he slowly crushed her in his powerful grip.
"Karai!" Leo cried, dropping down from above, slicing his swords along Slash's shell, forcing the larger turtle to drop her.
"So what's the deal, she Harry's replacement or something" Slash questioned, as he swung his mace around to meet Leo's blades.
Angered by the reminder of his youngest brother's absence, Leo pressed forward, clashing his weapons against Slash's. But he was so focused on Slash, Leo failed to notice the approaching Newtralizer until it was too late, and was knocked back by a surprise laser blast from the alien's weapons.
"It's time to go" said Newtralizer, throwing a razor disk at Karai and the Turtles, as they climbed to their feet – before teleporting away with Slash following closely behind.
Strangely despite his usual superb aim, Newtralizer didn't even come close to hitting them. They didn't have to wait long for the answer as a light on the razor disk started blinking, giving the universal signal of a….
"Bomb!" Donnie cried, prompting them all to start running for the exit. They only just managed to escape the building as the bomb went off bringing the entire warehouse up in flames.
"Everyone ok?" Leo asked, as the dust started to clear.
"No, we're not ok!" Raph snapped. "We would've somebody hadn't gone all lone wolf in the middle of a mission!"
"Hey, at least I wasn't waiting around doing nothing" Karai snapped back. "Besides, I thought you'd be used to working with someone that just randomly drops into the action!"
The Turtles didn't fail to realize the kunoichi was referring to Harry's use of teleporting in his fighting style. Of course while this bothered them all it was Raph's temper that was currently boiling.
"You're not Harry!" the red turtle roared. "You can't replace him! He's our brother you're just the idiot that lost him! Remember that the next time you decide to not work with the team! On second thought, why don't you just go! We don't need you anyway!"
Karai hadn't meant to sound as if she was trying to replace the missing Harry. She was just tired of taking so much crap from Raph.
"Fine!" Karai snapped, feeling just as angry. The kunoichi then took off, ignoring Leo's cries to stay with the team.
"Not cool, Raph" said Leo, glaring at his hotheaded brother "We all miss Harry, but Karai's trying to work with us."
"People have got feelings dude" said Mikey, agreeing with Leo. He missed his brother but he noticed how guilty Karai felt over it. "Real squishy feelings."
"Well I'm not people!" Raph said stubbornly. "Now let's forget about the princess and focus on finding Slash and the Newtralizer."
"Actually, I'm one step ahead of you" said Donnie, directing his brothers to the top of a nearby building.
Curious as to what the brainy turtle was planning Mikey, Raph, and Leo followed Donnie hoping that he had some trick up his sleeve.
"Ok Donnie, what're we doing up here?" asked Leo.
"We are going to listen in on everything Slash and the Newtralizer say" said Donnie, holing his T-phone. "While I was wrestling with Slash, I slipped a spy roach on him. We'll be able to listen to everything they say with my T-phone."
"Nice" Raph smirked. "And here I thought you were just getting beat up."
"Yeah well…uh I was multitasking." Activating the audio link to Donnie's spy roach the brothers listened in as Newtralizer's voice started to come through.
"The Kraang orb revealed a new weapon. They're testing it out on the docks at midnight. We can use it to wipe out The Kraang once and for all. We can destroy this whole stinking city."
"And every innocent human with it!" they heard Slash argue. "Are you crazy?! I'm here to take out Kraang – not people!"
"Why should I care? I'm not people!"
"Huh, sounds awfully familiar" said Mikey, taking shots at Raph's earlier statements. The red clad turtle just scowled at the comparison between himself and the psychotic alien.
"If it comes down to it I won't take any chances brother." Having heard enough Donnie then cut off the connection.
"Alright this just got real" said Leo. They couldn't afford to let Newtralizer get his hands on that weapon.
"Let's end this" said Raph, brandishing his sais in anticipation.
Arriving at the docks, the Turtles found the area was completely swarming with Kraang. Sticking to the shadows they watched as a squad of Kraang opened up a portal allowing large metal platform through from Dimension X.
"Is that the new weapon" Mikey questioned. "It doesn't look like much."
As if it had heard the orange turtle's comment the platform rose into the air as a colossal pair of legs unfolded beneath it.
"Uh never mind" the fun loving turtle chuckled nervously, as the giant Kraang walker stood at its full height.
From inside the mech a single Kraang smiled sadistically as it released the mech's rotating cannons. As the little brain squid started to get used to the controls its fellow aliens tried to direct it to perform a few tests.
Kraang 1: "Kraang move in the direction known as this way" the alien instructed, moving to stand by a shipping container.
Kraang pilot: "Kraang targeting – target." The Kraang walker then fired a laser blast at the container blowing it and its fellow Kraang's android body to smithereens. But the now droid-less alien didn't seem to mind as it held its tentacle up in a manner similar to a thumbs up.
Kraang 2: "That is what is known as awesome." The Kraang droids then held their hands up to the Kraang walker, wiggling their fingers in celebration.
But the Turtles weren't the only ones watching the new Kraang weapon; both Slash and the Newtralizer were also on the scene watching everything from their hiding spot amongst the shipping containers.
"So here's the plan" said Newtralizer. "You distract The Kraang – I'll highjack the walker."
"You expect me to trust you in that thing" Slash said incredulously.
"I know how to pilot it. and you don't have a choice."
Slash scowled as Newtralizer left to get into position; putting an end to The Kraang's celebration as teleported on top of the walker's cockpit.
But if the Newtralizer was hoping the pilot was going to panic; he was sorely disappointed as the Kraang quickly activated the walker's close-range defenses, deploying a taser gun stunning the alien lizard, and leaving him to his hard fall down to the ground.
With their cover blown Slash quickly joined the battle charging the Kraang forces as they opened fire on the intruders.
"Slash, keep The Kraang busy" said Newtralizer, recovering quickly.
And Slash did just that using his mace to savagely crush the aliens as he rushed through them like an unstoppable juggernaut.
With the docks now the scene of open warfare the Turtles decided it was best to step in. As his brothers and Slash mowed down the Kraang forces, Raph charged the Newtralizer – unwilling to risk letting the alien psychopath anywhere near the dangerous Kraang weapon.
But Newtralizer was quick to respond to brutally whipped Raph with his tail, knocking the red clad turtle back. Following up with his wrist mounted laser blaster, the alien had Raph on the defensive as the turtle bobbed and weaved around the dangerous blasts.
Seeing that he was going to prove a difficult target, Newtralizer closed the distance between them, switching from his blaster to his knife. A decision that may prove foolish as Raph expertly deflected the alien's blade with one of his sai, simultaneously swiping at the Newtralizer's gut with the other.
Newtralizer then found himself on the defensive, narrowly escaping the range of Raph's sai, the alien was finding himself pushed as the red turtle kept up a relentless assault.
Things only got more chaotic as the Kraang walker entered the battle, firing at anything that wasn't a Kraang – forcing Slash, Newtralizer, and the Turtles to scatter lest they find themselves deep fried from laser fire.
But as it turns out this was just the opening the Newtralizer needed. With Raphael forced to take cover from the Kraang walker, no one was able to stop the alien lizard from once again teleporting on top of the weapon.
Destroying the walker's taser gun with his blaster, the Newtralizer took great pleasure in tearing open the cockpit and throwing the Kraang pilot aside, smirking at the sound of the brain squid's screams.
Now in control of the Kraang walker, Newtralizer started firing on The Kraang, laughing as the alien invaders scattered in fear of being destroyed by their own weapon. So consumed by his sadistic joy in the suffering of his enemies, the Newtralizer didn't even notice that the lumbering movements of the walker was about to crush Slash. Lucky for him somebody did.
"Spike!" Raph cried, driven by feelings for his former pet, he tackled Slash out from under the walker's foot just before it could crush him.
"You…you saved me, Raphael" Slash was stunned, he had believed Raph had stopped caring for him, that their friendship had meant nothing.
Slash didn't have time to ponder these feelings as a laser blast from the walker just barely missed taking both his and Raph's heads off.
"I'll destroy you all" Newtralizer laughed, turning his focus to the Turtles.
Seeing as his partner had nearly killed him twice now, Slash quickly teleported on top of the walker, hoping to reason with him.
"What're you doing?" Slash demanded. "They helped us fight The Kraang."
"This is my battle!" Newtralizer said vindictively. "I don't need them."
It was clear to Slash now that unlike him, Newtralizer was more concerned with fighting Kraang, then actually protecting anyone. Feeling that he had no other choice, Slash took up his mace and slammed it into the hull of the walker, bending the metal around Newtralizer's tail.
"Slash, how could you brother?" Newtralizer growled, feeling betrayed.
"You're no brother of mine" said Slash.
Seeing that Slash's usefulness was at an end, Newtralizer aimed his wrist blaster at the turtle. But before he could fire, a shuriken came out of nowhere and took out the weapon. To both Slash and Newtralizer's surprise, they looked to see a smirking Raphael, hanging off the side of a shipping container, shuriken in hand.
Raph then leapt onto the walker to stand by Slash's side against the Newtralizer, but the crazed alien, simply jerked the mech forward, causing the two turtles to fall off.
"Raph!" Mikey cried out in concern, as he, Leo, and Donnie rushed to save him. As it turns out Donnie and Mikey were a great help as they unintentionally acted as airbags for Slash and Raph respectively. "Ugh, caught you, bro."
With Slash and the Turtles now bunched together, Newtralizer focused the walker's weapons on them. The alien took great pleasure in the fear he saw on their faces, as he prepared to end them all. Then the unexpected happened, just as he hit the trigger to fire the weapons, the energy crystal powering the walker suddenly exploded violently, taking both the walker and the Newtralizer with it.
Slash and the Turtles were stunned as known of them knew what could've caused it; the answer soon revealed itself, as Karai dropped down in front of them.
"Booyakasha" she smirked. "Huh, that really is fun to say."
"Karai?" Leo gasped, he couldn't believe she had come back. "How, did you do that?"
"I borrowed one of Donatello's bombs before we left" the kunoichi explained. "I threw it into some kind of exhaust port or something in that thing's hull. What can I say? I appreciate a quality explosive."
"Oh yeah, way to go, sis!" Mikey cheered, pulling Karai into a hug, surprisingly getting a smile from the usually tough as nails, kunoichi. While Donnie enjoyed the praise of his work and gave his own thanks for the save.
While his brothers were showing their gratitude to Karai, Raph felt it was a good time to try and mend bridges with Slash.
"Thanks, Spike…I mean Slash" said Raph, smiling slightly as he proposed his idea. "You know, there's always room for one more."
"I need to go my own way, Raphael" said Slash, though he appreciated the offer. "I think I'm better off, solo." Though he noticed Raph's disappointment, Slash's mind was set. "Goodbye, brother. I'll see you again…someday."
And with that Slash teleported away.
"Goodbye, Spike" Raph said sadly.
"Hey, look" Karai said uncomfortably, walking up to Raph. "I know; I don't really know how much Slash mean to you. And I agree, what happened to Harry, is my fault. I'm not trying to take his place, and I know I've got a lot to learn about really being a team. Just know I want this to work."
Leo, Mikey, and Donnie waited to see what Raph's response would be, wondering if perhaps, Karai had chosen the wrong time to try and work things out between them.
"Fine" Raph sighed. "Once we get Harry back, you can tell him how bad you screwed up. In the meantime, you better get it together if you're going to be working us from now on."
Karai smirked at the response, understanding it was the best she was going to get.
So with that Karai and the Turtles left for home. Things were still going to be a little rocky but it was starting to look like just maybe they could go last long enough to bring their family together again. Maybe even stronger than before.
