"Almost there..." Spy said to himself. Currently, he was cruising underwater using his Invis Watch and DPV to move unnoticed. Abyssal SONAR didn't work on the mercenaries for they were not ships, so no one suspected a thing. However, they were on guard after he revealed himself to the Battleship Princess, though they weren't able to find him again after that even as he sank some more unsuspecting ships.

In his arms was the large exploding part of a Sentry-Buster, the part that looked like a naval mine. When the mercenaries saw the Battleship Princess and her big ass demon, they knew she wasn't going to be easy to beat. That was back when before the Fleet Girls arrived or they even knew they existed, but the boys already came up with a plan to deal with her without getting blown the fuck up by her guns. Spy swam all the way back to the cargo ship where a Giant Heavy-Bot tossed him a Sentry Buster to use in this mission. He had to wait a while for the Battleship Princess to be distracted so he could make his move, so he had been just quietly killing a few Abyssal ships the whole time the battle was unfolding. Once an opportunity to attack her opened up, he picked the bomb back up and went right to work.

Upon reaching behind the Battleship Princess, still cloaked, he stuck his head out of the water and observed the massive backside that was the huge bio-mechanical demon she was connected to. He grinned to himself. This was going to be ridiculously easy.

...

The Battleship Princess watched the battle unfold. Her forces were bombarding the Hell out of the Fleet Girls and the pesky Humans she hated so much. A large front-facing energy barrier was preventing their barrage from scoring any more damage, but the problem could easily be solved by flanking around the shield and closing in. The shield couldn't cover them from all sides. The planes launched by the Fleet Girl carriers had been all shot down at this point, and the constant shelling of the Fleet Girls' formation meant that they were unable to launch anymore. She petted the huge head of the demon that held her, and she smiled. Victory was assured after all. They will all sink.

"GRRRAAWAWWGH!" The demon symbiote roared out, it's roar being loud enough to shake the air. Battleship Princess also cried out, for she was suddenly in intense pain. Blue shocks of electricity sparked all along both of their bodies and they were unable to do anything else but scream in agony. After what felt like an hour, the shocks eventually stopped. She fell to her knees, breathing heavily just as her pet was.

"Awww~ What's the matter?" She heard someone say. This voice, she recognized it.

"You..." She growled, managing to lift herself up enough to see the same masked man who's been frustratingly sinking her important ships undetected left and right. Spy had attached a Sapper to the demon and floated to a safe distance to let the Sapper stun the Battleship Princess to submission. Now he was on top of her precious pet's head, with a... NAVAL MINE!?

"Oui. Bonjour, mon cheri." He nodded politely with a mocking grin. "Well, I would love to stay and chat, but I'm sure you and your pet can't wait to play with this new toy." He snorted, jumping down into the water. Only that he never even touch the water, for the demon grabbed him. It let out a monstrous roar of pure rage as its massive fist held Spy in a crushing hold. Spy ended up flailing around helplessly like a little doll. The Sapper didn't keep them stunned for nearly as long as he had expected, and now he was completely at her mercy.

"Foolish Human..." Her otherworldly voice said as she stood up, glaring at his struggling body. "I will crush you..." Then, she held her right hand out, and slowly closed it. Turns out the term 'Symbiotic Princess" that's also used to describe her was very accurate, for the demon was now crushing him in his hand. They were one, her and the demon. The demon's giant hands were her hands, and she seemed to take some pleasure in slowly crushing Spy with her hands.

Spy could feel his ribs about to break at any second now. His internal organs were gonna pop, and soon he was going to literally pop like a balloon himself if he didn't do something to save himself. His saving grace soon came when a bright red laser shot suddenly pinged off of Battleship Princess' energy shield. The shield was drastically weakened from the sapping, but it was enough to stop Sniper's shot from coming through. At once, she held her other arm up to have the demon cover her vulnerable body as Sniper continued firing. Now was his chance. Spy reached for his coat pocket and got out the Ambassador, fiercely struggling to take aim at her while she still squeezed him deadly tight.

Battleship Princess noticed this however, and her demon bellowed in anger. Before Spy even knew it, he was sent flying out into the sky at a fast pace. The Battleship Princess temporarily redirected her attention at Sniper's position for he gave himself away with the decision to use the Machina and bombarded the Hell out of it.

"Sniper, now!" He yelled.

Near instantly, the naval mine blew up. The Battleship Princess was so focused on covering herself up that she had forgotten about the Sentry-Buster mine on top of her demon's head. This left it wide open for Sniper to shoot at, and she barely had time to react to her mistake as her position blew up into a massive fireball. The fireball was so massive, that the force of the explosion both set Spy on fire and made him fly even further and faster.

*KABOOOOOOM!*

"WHAAAATT!?" The Fleet Girls screamed together at seeing the Battleship Princess blow up so suddenly.

It was almost like she was struck by a Submarine, only that the explosion was way bigger than any torpedo. It was just so unbelievable to them how a normal Human man can sneak up to one of the more dangerous varieties of Abyssal and just detonate a naval mine in a daring move. The attacking Abyssals stopped and immediately rushed over to the burning fire where the Battleship Princess once was, leaving the Fleet Girls free.

"Hahaha! Good work you sons of bitches! Now that is how it's done!" Engie hooted. He even gave Spy a thumbs up as the smoking Frenchman flew through the air towards them like a flaming dart. "You alright Sniper?"

"Yeah, I'm good. She almost got me though." The Australian's voice responded.

"Alrighty then. Boys, comms are open. I repeat, comms are open."

"The Hell does that mean?" Scout asked.

"It means you can talk on the radio now, dummy." Engie answered. You see, the mercenaries had to maintain radio silence for this plan to work. If Spy had suddenly received a transmission as he was trying to sneak up to the Battleship Princess and she detected it, then this adventure would have ended a whole lot differently.

The boys were overjoyed that this plan actually worked and were cheering in victory with the Fleet Girls soon joining in after getting over their shock. Their half-assed plan boiled down to this, attack the enemy, don't use the radio, distract them for Spy, and then Spy blows her and her big ass demon up. Boom, simple as that. Only that it was made a mixture of easier and complicated when the Fleet Girls arrived. Easier in that they were an even bigger distraction, but complicated in that the battle became a clusterfuck with Spy having to dodge explosions from missed shells and shit while underwater.

"Team Fortress rules! Baby!" Scout hollered. If they weren't on water right now or being carried by Ship Girls, they'd totally be dancing right now.

"Team Fortess, huh? Hmm... that's a nice name." Atago said with all her good nature.

"Oy! You lads see that explosion?" Sniper made his presence known as he swam toward them, a great smile on his face from the successful shot.

"Um, I don't mean to worry anyone, but is your friend okay?" Jintsuu asked, looking down at Spy as he floated toward them. He was facedown in the water, and he was completely motionless. Concerned, Sendai and Naka picked him up where he had no reaction at all.

"Hmm..." Medic hummed as he closely looked at him. "Eh, it looks like ze explosion killed him." He said casually as if it was not a big deal. It still scared the Fleet Girls though. To them at least, any sense of joy was lost, even if the mercs were strangely perfectly fine with this. "If not zat, then maybe ze had impact with ze vater broke his neck..."

"I-I... I'm sorry for your loss." Fubuki apologized, instinctively giving Medic a hug. The mercs awkwardly watched as most of the Fleet Girls gave them comforting hugs that ironically didn't make them comfortable. It only got more awkward for them when the younger Destroyers began crying.

"Huh? Oh, zer's no need to worry girls. He'll be okay." Medic assured them, giving Fubuki a pat on the back and kindly messing up her hair a little.

"What? But he's dead!" Tenryuu said.

"Ja, but not for long. Please, if you vill, take us back to our ship. I got equipment zat vill help him. It's much more preferable to do it on a solid surface zen out here on ze vater." He said.

Not completely sure where he was going with this, they nonetheless complied with the offer to take them back to their ship. The Abyssals were still in the area, except they wouldn't leave the burning flames of where the Battleship Princess once was for some reason. Normally, they'd be retreating by now at the loss of their leader. especially when one considers that out of the huge force gathered here, only about nine of the humanoid Abyssals remained, not including the four remaining Wo-Class Aircraft Carriers since they were out of planes and not really a threat anymore. The escort force was completely gone. All of their Destroyers and Light Cruisers were sunk in action.

The mercenaries were more than happy to let them onto their heavily damaged ship. All the fires had been put out and extensive repairs had been done since the battle prevented the Abyssals from continuing their attack on the ship. The hull breach wasn't sealed but it was contained so that flooding in the lower levels was no longer an issue. The engines were also finishing up on repairs. All and all, the ship was ready to be operational again. It genuinely impressed the Fleet Girls with how long they held out just using this civilian vessel, and also how much punishment it was able to take. Also, the robots were a pleasant surprise. Only more evidence to the unsettling truth that they weren't from this world.

"Gee, you guys sure put up a fight before we got here..." Kongou whistled at all the holes punched into the ship from enemy fire.

"Are those robots?" Takao asked once she realized the other 'people' on the ship weren't people at all. Her answer was a hum of confirmation from Pyro.

"Hi robots!" The ditzy cute Atago greeted them, to which some of the robots were kind enough to wave back.

"Why do they look like them?" Tenryuu whispered to her sister, who for once had nothing snarky to say.

"Welcome aboard the USS Fortress! The greatest American vessel to sail the seas!" Solder said proudly. Obviously, this ship was not associated with America or the United States Navy in any way, and they casually dismissed him about it. The only USN ships these girls knew were Iowa and Saratoga.

"This ship is heavily damaged. Can you guys even move this thing?" Kongou asked.

"Working on it. Got some bots down below working on it as we speak." Engie answered.

Now everyone was relaxing aboard the ship, happy to get a break after that intense battle. The only issue preventing complete comfort was the smell of smoke, and how there was a dead man with them. Speaking of which, Medic had gotten out another strange device from out of nowhere, and placed it on the ground. Considering how the Fleet Girls were impressed with the Sentry Gun, Medigun, robots, and Dispenser, they were more than curious to gather around the new device to see what it does. When the device was activated, a life-sized red hologram of Spy was emitted from the very middle, scaring the girls back in surprise. Whistling to himself, Medic fixed his Medigun onto the device and focused the beam into it. Out of nowhere, Spy's limp body began floating toward the device until it perfectly fitted the hologram, and then poof! In a flash of light, he was alive again.

"Oww... Vielen Dank, Doktor." Spy rubbed his aching neck, thanking Medic in his native tongue of German.

"Bitte!" The German responded happily.

Okay, so healing machines were one thing since the Fleet Girls had something similar in the form of their healing baths back at the docks, but this? Bringing people back to life like this? This was something they couldn't believe. Particularly, the less mature members of the fleet started hollering and cheering wildly, unable to control their excitement and disbelief after witnessing that.

"You guys are even cooler than I thought!" Kongou screamed with the excitement of a full on child, grabbing the two nearest mercs and crushing them in a big ole hug. The unfortunate mercs to receive her loving embrace were Sniper and Scout. The sheer strength of the Battleship was making the mercs feel like they were getting turned into pasty mush, their bones trying hard not to crack.

"You have to come back with us to the Naval District! Everyone is going to love you guys!" Kirishima cheered.

"With your help, we can clear the Abyssals out of this region and make them go poi~!" Yuudachi said, gaining approval from the other girls. The mercenaries hadn't received this much attention since they became professors in Remnant. Which reminded them, they actually missed the friends they made back in that world. It's been a few days since they last seen them. Once they were done delivering all the bullshit in this ship to the Nippon Division of Mann Co. in Tokyo Bay, then they'll go back to Remnant.

"We would like to, but Heavy and friends have job to do. We must bring ship to Japan." Heavy said.

"Pffft, you're already close to Japan!" Hiei laughed. Welp, that explained why they all have Japanese names then. "We can escort you there, maybe you can even stop by our Naval District on the way."

"Haruna thinks the sailors will be more than happy to repair your ship." Haruna said in her unusual third person way of speaking, though Heavy spoke like that too sometimes so it's good.

All things considered, the girls were getting along fabulously well with the mercenaries. After getting a chance to actually spend time with them outside of combat, they quickly found that some of them are a little... quirky, to put it lightly. The two that stood out the most were Soldier and Pyro. Pyro was a strange person who was always in a fireproof suit, acts very childishly and creepy at the same time, nobody except the other mercenaries can understand what he was saying, and he was extremely friendly to anyone who bothers to be nice to him. Pyro brought out one of his many Balloonicorns and gleefully let the Destroyers have it, much to their delight since it was so adorable. Soldier was a downright insane American patriot who thinks everything revolves around America vs evil/communists/Nazis/hippies/Tom Jones.

Well, at least these men were on their side. They were thankful for that much.

While the mercenaries weren't too concerned about it, the Ship Girls did feel somewhat uneasy that the Abyssals wouldn't leave the burning spot where the Battleship Princess once was. She was defeated rather easily enough by the mercenaries, and normally an Abyssal fleet would scatter and retreat after a high class ship like that had been destroyed. Clearly, something was not right. Whatever it was, the Ship Girls decided to do something about it. The girls hopped off the ship and prepared to finish off the enemy. Thanks to the mercenaries, they were more than fit for battle. Not like it would have mattered much anyway since there wasn't a lot of enemies left.

"Please wait for us while we deal with them." Akagi told the men as they departed.

Even if they did choose to leave while they were engaging the Abyssals, it didn't worrry Akagi all that much. Their ship was significantly slower now that it was damaged, and that meant the Ship Girls could easily catch up to them whenever they got done with the enemy.

When the girl's sailed maybe fifty meters out from the cargo ship, something pretty interesting happened. It turns out the Battleship Princess wasn't sunk at all, only extremely, and that would have to be a really serious extremely, damaged. The Sentry-Buster detonating right on top of her had most definitely took a heavy toll on her. The demon she was attached to was oozing dark purple blood everywhere, was riddled with shrapnel, covered in fire and scorch marks, and it had most of its right arm blown clean off. It also appeared to be dying, or rather it's already dead since it wasn't moving in the slightest. The Battleship Princess herself could barely stand on her own two feet. She was bleeding just as heavily as her demon was, but she was still breathing at least.

Evidently, the demon had given its life to protect its master. It seemed like despite being a so called "symbiotic" princess, she didn't necessarily need her demon to survive.

With the Ship Girls incoming, the remaining Abyssals kept close to their leader despite there being no hope for them whatsoever. Which completely changed into their favor as another Abyssal fleet was approaching from the north. It caught the Ship Girls off guard alright, but strangely enough it seemed to surprise the broken Abyssal fleet as well. It's almost as if they weren't supposed to be here. The Battleship Princess knew for damn sure that the incoming fleet in particular wasn't even deployed in these waters.

And then, something even stranger happened. Out of nowhere, a huge cloud of fog literally materialized out of thin air, and it was rapidly covering the area. It came from the direction of the mercs' ship where it engulfed them first, and soon it was going to cover the Ship Girls from how ridiculously fast this fog was moving. It didn't even seem like the fog itself was moving. It felt more like the fog just formed right on top of them and was happening to be spreading towards them.

"Mr. Conagher! Are you alright back there?" Akagi radioed back to the mercenaries, worried about them when their ship disappeared in the fog.

"THIS IS THE SAME DAMN FOG-" The Texan yelled before the radio connection was immediately silenced. Only static remained.

"Same fog? What do you mean? Hello!?" Cried the Carrier, but no voice responded. Just the eerie static.

The disappearance of the mercenaries would have to be the least of their concerns, for the fog was now right on top of them. Vision was completely obscured. So much so that the girls literally could not see their own hands when held right in front of them. Absolutely nothing was visible in this supernaturally thick fog. They lost sight of everything from each other to their very enemies who were in no doubt also covered in this fog.

"I can't see anything!" Fubuki's voice cried out in the fog.

"Everyone stay together! Stop moving! We can't lose each-" Akagi was about to finish that sentence when something equally as unusual just happened.

The fog suddenly cleared just like that. Just like how it initially randomly dropped the mercenaries into this world, it disappeared just as quickly as it showed up. What's even stranger is that this was definitely not where the battle group was only a few moments ago. Why, you might ask? For starters, they were back at the Naval District. The open ocean they were previously in less than five minutes ago was gone, and it was replaced with the familiar scenery of their home base. In fact, they were right at the docks they would gear up for sorties from. What's more is that the Abyssals were gone, and so were the mercenaries.

"...other."

"Um... what... happened?" Asked a completely bewildered Sendai.

None of them said a thing because they needed a moment to take it all in, but nobody would have had an answer anyway. While the battle group stood in the middle of the harbor in awkward and stunned silence, the other fleet girls here were surprised to see them suddenly appear out of nowhere.

Later on, Akagi and her group found out that this same strange fog had covered the entire Naval District as well. What's more is that it actually also appeared earlier here at apparently the same time she and the others engaged the Abyssals and first encountered the mercenaries of Team Fortress. It seems as if this anomalous freak fog had appeared at multiple places, and it was apparently responsible for teleporting them and others around. I say 'others' because some of the Ship Girls here had momentarily disappeared after it came, and crazily enough, some Abyssals randomly popped up in the base. Now that would have been shocking enough if it weren't for other equally as mind numbing details as several strangers also popping up around the base.

The Abyssals that showed up here were quickly captured without too much trouble since they were at a horrible disadvantage here all on their lonesome. They were going to be interrogated and stuff had the fog not mysteriously appeared again, and it made them and all the strangers vanish. It also made all the missing Ship Girls reappear, conveniently at the same moment Akagi and her group did, and boy did they have quite the stories to tell in their brief moments away from the District.

Today was a weird day...

Truly, it was.

No matter how weird it was though, there was no denying that it did happen. Somewhere out there was the unusual and strange men of Team Fortress, and although they didn't know them for very long, they were disappointed they couldn't bring them back to the Naval District. These friendly men could have turned the tide of the war with their almost magical technology. Things would be so much easier for the Ship Girls if they could heal and resupply whenever they wanted, and that's not even mentioning the ability to come back to life.

Tokyo Bay, Earth (TF)

The mercenaries had no idea what just happened, but all they knew was that they were somehow at their destination. There were some serious questions about what the actual fuck just happened, but in the end, the boys didn't really care all that much. All they wanted was to finish this job and get their rewards.

While they brought their fucked up cargo ship into port where it will be taken in by the Japanese division of Mann Co., they had no idea that they were just part of a phenomenon called a "portal storm". These portals can take on any shape or form, and in their particular case, it took the form of extremely thick mist that took them to the world of Kantai Collection. Portal storms affect entire universes, creating portals that can either drop people into other parts of the world they were already in, or taking them to completely different worlds.

And in this timeline, the portal storms are still raging...

Okay, so that wraps up this little story. This was never supposed to be a full length thing, so I decided to end it here on a four parter before things got hectic and confusing (It's also because I got a lot of unfinished stories to get to and this one was the closest to getting finished anyway). All this was supposed to be was a relatively short story of the mercs finding themselves fighting against the Abyssals. Just a fun thought that spiraled into four chapters somehow. My whole multiverse storyline I got going on is starting to branch into different timelines and shit. So much so that my very head is starting to hurt just by thinking about it.

I don't know. Maybe at the very least I'll make a separate series of crossovers based on the "Portal Storm Timeline", which is what I'm calling this right here. All stems from a slightly different version of the original

Maybe a standalone crossover will be made between Team Fortress 2, KanColle, RWBY, or one in all. I already got ideas. A crossover which will be more thought out of course. If I do make another one, it's going to be significantly better.

Review Responses:

The Guy Who Makes Unfair Deals: Indeed.

FuryFire: What have ye done?

The Mercenary Prime: Is you alright?

pastor: Probably not. I haven't played The Division, but it's not something I am really interested in.

Saber Knight: Ayyyyyy.

Game2002: I have not decided on that. The mercs will obviously not find out this time, but maybe in a separate timeline they will if I do make another crossover of these series.

Guest: Yeah, you guys should probably talk about this on a forum board or something.
