Earth Protection Force - New York, NY, USA

A group of men and women in suits rapidly walked down a corridor, many of them carrying weapons and equipment. They were accompanied by military personnel, who were also armed, and a man leading the group. This man also wore a suit and had sunglasses to match. His gait appeared robotic.

The group turned a corner and finally arrived at their destination: a large laboratory with machines one could only dream of. Industrial-sized robot arms could be seen at all corners of the room; monitors could be seen lined up next to each other along three of the walls, standing next to devices that produced holographic images; and large openings were found across another wall with sensors lining the gaping holes. At the center of it all was a large disk-shaped apparatus that covered about 50 percent of what was left of the floor.

"I've received word that the quantum portal has been acting sporadically," the man at the front of the group confirmed. "Do any of you know what's been causing it?"

"Absolutely no clue, Bishop," one of the scientists answered. "We've contacted Donatello to see if he knew anything about it, but according to him, it doesn't seem to be giving off any interdimensional energy."

"Then where's it coming from?"

"It appears to be coming from...Earth," the scientist said as Bishop took off his sunglasses in shock. "What should we do?"

Bishop thought about it for a bit, but before he could come to a decision, the machine at the center lit up and gave off an enormous surge of energy, pushing back everyone in the room. Emerging from the explosion were a man wearing a white hat with bear ears and a yellow bulldog.

"Woah! Where the bjork are we?" the dog spoke. Some of the agents were taken aback.

"Did that dog just...talk?"

"Must be a mutant," one of the soldiers suggested. "Should we fire?"

"Who're you callin' a mutant?" the dog retorted. He lunged forward a bit to attack the agent, but the man held him back before he could do any harm.

"C'mon, Jake!" the man responded. "Not now! We gotta get outta here!"

Just as the man started to walk away from the machine with his dog still in his arms, several agents activated their blasters and pointed them at the two, who immediately stopped in their tracks.

"Hold it right there!" Bishop commanded. "We're gonna need to take you in for questioning. Know if you're on our side." Then, seemingly out of instinct, Jake extended his front legs towards the agents, knocked some of their weapons out of their hands, and knocked the agents themselves unconscious.

"C'mon, Finn!" Jake said. "Let's get outta here quick!" He wrapped Finn in his now enlarged hands and ran off. The remaining agents lunged for whatever weapons they could reach and continued firing. All their firing was in vain, however. What was once a regular-sized bulldog with freakishly oversized hands was now the size of a house. After placing Finn on his back, Jake charged the group of agents. Those who weren't fast enough to move out of the way were immediately trampled. They were all alright, but badly hurt. Finn and Jake managed to escape the facility. Red lights blared throughout the building as an alarm rang throughout.

Bishop rushed down the halls, looking for one room in particular. He finally reached his destination, which fortunately still had someone in there.

"General! Status report on where those two are headed?"

"One of our men managed to plant tracking devices on both of them," the man responded. "It seems they're headed west. What do you want us to do, Bishop?"

"I think we need to call in some extra help," he finally decided.

"But sir, it's been a long time since we've ever called them in for a fight. Are you sure they'll be up for it?"

"Absolutely positive."

Fenton Works - Amity Park, IL, USA

The basement was littered with crumpled blueprints and gadgets and devices. Empty coffee cups could be found throughout the room, while the only person in the room had a full one in hand while observing some data he had on his computer screen.

"Hey, Danny!" a voice called from upstairs. A woman with a leather black skirt, a velvet purple tank top, a matching purple bow in her dark hair, and combat boots came down the stairs. "Are you still down here?" Danny turned with a jolt.

"Huh? What time is it?" Danny asked.

"It's seven in the morning," his wife, Sam, told him. "How long have you been up?"

"Really?" Danny immediately got up and started gathering some of the blueprints that remained on his desk. He then plugged a flash drive in to his computer and pressed a button on his keyboard. "Oh God, I'm gonna be late!"

"Were you up all night getting ready for the board meeting?"

"Apparently." Danny continued to gather all his things with a partially unbuttoned dress shirt and an untied necktie. "I've been spending most of my time trying to finish the exact solution I needed to prove the relationship between the ectenic force found in ectoplasm and wormholes. I've been able to replicate some of my dad's old work on the Ghost Portal to see what I could find, but the results are still unfinished. I dunno what I'm gonna tell the board of directors."

"Well, can't you just resechedule?" Sam suggested. "Ask for more time to finish the solution?"

"I could try, but we're scheduled to discuss the company's budget today, and since they plan on discussing what to cut, I really need something substantial to show them."

"Well, whatever happens, I'm here for you," Sam comforted him. As Danny finished tying his tie, he gave Sam a peck on the lips. He then grabbed his briefcase and coffee and unplugged his flash drive before heading out.

Just as Danny left the building, he saw a stampede of frightened people rushing his way before seeing what the cause of all this commotion was. At the back of the crowd was a skinny man riding a giant yellow bulldog.

"What the hell?" Danny muttered under his breath. He immediately dropped his briefcase and uttered three words he hadn't said in a long time:

"I'm going ghost!"

And just like that, two bright rings encased his body. Pretty soon, his work clothes transformed into a black and white body suit, his jet black hair turned snow white, and his baby blue eyes turned lime green. Danny immediately sprung into action.

Danny slammed his body into the large dog's and carried him away from the crowd. As he approached a building, he made himself intangible along with the man and the dog. Soon after, the three of them rammed through the walls and came out from the other side. Once they were clear of any civilians and buildings, Danny pinned the other two down on the ground.

"Alright, I don't know who you guys are, but you're sure as hell not gonna go around terrorizing my town!"

"Terrorizing?" the man questioned in a perplexed tone. "We were just trying to get back to Ooo."

"Yeah, dude," the dog added, surprising Danny as a result. "If anyone's terrorizing people, it's you."

"Woah, is it just me, or did that dog just talk?" Danny asked.

"Alright, why is everyone surprised that I can talk? Of course I can talk! Every dog can talk for Glob's sake!"

"Uh, no. Dogs can't talk."

"What? That sounds bunk."

"Okay," Danny said, still confused. "Well, I'm still gonna have to take you guys down."

As Danny lunged himself towards the two of them, the dog extended his arms upwards, hooked them to a window sill, and lifted himself up with the man still on his back. Danny stopped in his tracks and immediately followed the two.

"Oh no you don't!" Danny slowly increased his speed, and as soon as he caught up with them, he grabbed ahold of one of the dog's legs and pulled hard. He successfully managed to throw the two of them down to the ground. The impact cracked the street and shattered several windows, but fortunately, no one was hurt.

"Alright, now I'm only gonna ask this once," Danny demanded. "Who are you two and what are you doing here?"

The man climbed down from where he previously sat on the dog.

"I'm Finn, and this," he pointed to the dog, who now shrunk down to the size of a regular bulldog, "is my brother Jake."

"Right," Danny responded. For someone who has dealt with the supernatural ever since his high school years, this seemed to be the weirdest encounter he has ever faced.

"Anyway, I'm not entirely sure how we got here, but we've been looking for Princess Bubblegum."

"Princess Who-Now?"

"Princess Bubblegum. You know, the ruler of the Candy Kingdom?" Jake informed him.

"Sorry. Never heard of her."

Finn gave out a great sigh. "Aw, man. Now what're we gonna do?"

"Don't look at me," Jake answered. "I was kinda hoping we'd find Bubblegum so she could help us get back."

Danny thought about it for a moment, and then an idea immediately struck him.

"Well, I have to go to work right now, but before I go, I can drop you off at my place. Until my wife and I come back, you guys can crash there if you want," he told them as he transformed back into his human form. Finn and Jake both looked at him in shock.

"You'd seriously do that for us?" Finn asked.

"Why not? It's the least I could do for you after attacking you guys out of nowhere."

"Thanks, dude," Jake said, followed by an "Awesome!" from Finn.

Earth Protection Force - New York, NY, USA

Back at the EPF's laboratory, several scientists were joined once again by their leader, Bishop, and this time, they were also joined by four other people: April O'Neil, Casey Jones, Karai, and Shinigami.

"So, let me get this straight," Karai asked. "Some guy broke in here with his talking dog and just ran off?"

"Yes," Bishop replied. "That would be an accurate description of events."

"Why do you think that happened?" April asked.

"So far, we don't have any conclusive answers. We've tracked them all the way to Illinois so far, but they seem to have stopped there."

"Well, then how about we head there now?" the redhead suggested. "I'm sure the turtles could use our help dealing with whatever's going on."

"Yeah," Casey chimed in. "It's been a while since I've bashed any heads in."

"Sorry, Casey, but we don't need any more assistance than we already have."

"Oh, come on!" Casey cried. "Can't I just go there and throw one puck grenade?"

"It would be nice to actually help out," April said. "We are just as capable as the turtles are."

"The turtles are able to hold their own out there. We need you four to..."

"To do nothing while the 'true heroes' go out and fight?" April retorted, causing the other three to gasp in shock.

"Miss O'Neil, I understand your frustration," Bishop told her, "but you need to calm down."

April sighed. She didn't want to calm down. She wanted to join in on the action. It stung that she and her friends often played second fiddle to the Ninja Turtles.

"I'm sorry," she said more calmly this time, "but I just want to do more than just stand around and wait to be called."

"True as that may be--"

Before Bishop could finish his rebuttal, the machine reactivated. Everyone in the room stood back as someone seemed to materialize from this second surge of energy. Just as the sparks dissipated, a woman with robotic implants emerged with just one question: "Where is Finn Mertens?"

"Who wants to know?" Casey inquired as he grabbed his hockey stick and held it in a fighting stance. Everyone else pulled out their weapons as well, ready to fight.

"Call me Dr. Gross."
