I do not own Star Vs. The Forces of Evil or Castlevania

For my first fanfic, I decided to write a crossover that nobody asked for or even thought of. Though this story is going to be more halfway between an AU and a crossover, it's mostly going to be a Svtfoe story with Castlevania elements thrown in (though, that might change later). It might be awhile before any true Castlevania characters even show up.

This first chapter is fairly short, and serves as more of an introduction to the story than anything else. It starts smack dab in the middle of 'Running with Scissors' so if you haven't seen the episode in awhile you might be a little lost.

Star hung up her mirror phone and looked at the ominous red portal. Her conversation with Pony Head had left her worried. Marco was on the other side of that portal. She took and deep and spoke with determination, "I'm coming Marco." and strode through the portal.

Star entered into a frankly nightmarish landscape, filled with dead trees and a smoking volcano in distance. After looking around for a moment, she picked a direction broke into a sprint, hoping that she was going the right way. Fortunately, her sense of navigation had been right and she soon found herself at the front door of Hekapoo's forge. It resembled a large tree stump with smoke billowing out of the top. Clutching her wand tightly, Star ran up to the door and kicked it open. Inside stood two people, Hekapoo and a large man, along with a creature that looked like the combination of a dragon and a motorcycle.

"Hekapoo!" Star shouted, leveling her wand at woman, "Where's Marco?"

"Star!" the man exclaimed in surprise, before running over and pulling Star into a bear hug. He was incredibly strong, and Star feared that she would be crushed. She struggled for a second before finally prying herself away. As air filled back into her lungs, she finally took a good look at him. He was tall, much larger than she was, and incredibly muscular. The open biker jacket he wore showed off his amazing abs and toned arms, one of which bore a tattoo. His face was handsome, and the scar over his left eye and the shadows of a bread on his face gave him a mysterious air. But Star didn't care how attractive he was, she didn't know him and he had just grabbed her. She pointed her wanted directly at his chest.

"Unhand me, beautiful stranger!" Star ordered, before suddenly realising that she had just called her by name, "How do you know my name?"

"It's me, Marco." He responded, taking off a tattered red hoodie that Star had originally mistaken for a bandanna, "See?"

"Marco?" Star asked, confused. She looked at him again, noticing the small yet unmistakable mole on his face, before her eyes moved downwards to the newer parts of his appearance. Namely his abs.

"Marco." She said dreamily, soaking in his new body.

"Oh man! We have so much to catch up on!" Marco said, clearly excited to talk to his old friend again, "I've learned how to sword fight, I fought an army of Night Creatures, I rode in a hot air balloon, I killed a god!"

Marco continued to talk, though Star didn't hear most of what he said. She was more focused on his abs. One can hardly blame her, she was a teenage girl after all, and adult Marco was easily the hottest guy she had ever seen in person.

"And then, I jet skied off a waterfall! Isn't that cool?" Marco asked, having finished recounting his various adventures, "Oh, check it out! It took me sixteen years, but I totally earned these scissors." he said, holding up a pair of sword-like dimensional scissors.

"Whoa, whoa, wait?" Star shook her head, his word having snapped her out of her stupor, "Sixteen year!? You've been gone from earth for like, eight minutes."

Marco just stared at her for a second before becoming angry, "Eight minutes!?"

"Yeah" Hekapoo spoke for the first time since Star arrived, "I forgot to tell you that time passes differently in this dimension. Not sorry."

Marco simply gave her an indignant glare. He had grown used to this type of behavior from Hekapoo during his time spent in her dimension. He thought back to the time when she conveniently forgot to mention that the Exploding Plains of Flendar, well exploded. He didn't hear the plains' full name until after he'd already been blown up. Looking over at Star, he probably should have realised that something weird was going on, considering that she hadn't aged at all since he last saw her.

"No, no, no, no. This is good. It means you haven't missed anything back on Earth. Come on, use your new scissors to take us home." Star eagerly said.

"Yeah, about that." Marco said, becoming very melancholy all of a sudden, "I'm not coming back, Star."

"What! Why!?" Star yelled in surprise, trying to wrap her head around Marco's words.

"A lot's happened to me Star, stuff I can't even begin to explain." Marco spoke slowly, looking at the ground and away from her, "I've changed, and I've learned things. It would be for the best if I didn't come back."

"Wait, but what about your parents? Or your friends?" Star asked, trying desperately to get her best friend to change his mind. The idea of Marco just leaving was horrible, "Or, me?"

Marco refused to look at her, he was worried he might change his mind if he did. He missed her, and his parents and friends. Being reunited with Star after sixteen years made prospect of never seeing them again seem much harder than it did before, when he first decided he wouldn't go home. Would it really hurt to go back? Marco turned to Hekapoo looking for some help with the decision before him.

"Don't look at me. It's your life." Hekapoo said with a shrug, before adding, "But you should probably head home, it'd be good for you."

Marco gave her a smile, glad to have have her support toward the idea of going home, before turning back to Star. She smiled in relief, happy that he was coming back. Marco took his scissors, snipping them experimentally then cutting open a portal to earth. He turned and walked over to Hekapoo and the dragon-cycle.

"Please, take care of Nachos while I'm gone." Marco said, before leaning down and hugging the dragon-cycle.

"She's in good hands." Hekapoo responded, patting Nachos.

"Adios, boo-boo." Marco said, kissing the dragon-cycle on the snout. He stood up and addressed Hekapoo, "Well, old friend, you really gave me a run for my money."

"Likewise. You're pretty cool." She said, before reaching behind him and smacking the back of his head and laughing.

Marco rubbed the back of his head, a fairly large bald spot having formed there from all the times Hekapoo had smacked him with her burning hands. "Thanks by the way" He said, "For, well you know."

"Don't mention it." Hekapoo responded. She then shot a glance at Star, "Seriously, never talk about it."

"I won't, believe me." Marco told her.

"Come on, Marco! Let's go." Star called from the portal, which she was already halfway inside. Their cryptic conversation had made her curious, and as Marco approached she asked, "What was that about?"

"Nothing." was the only thing he responded with. Star was tempted to press the issue but ultimately decided against it. Marco would never keep anything big a secret from her, so it was probably just something dumb and embarrassing.

"Okay." Star said, before waving goodbye to Hekapoo, "Bye." and then fully headed through the portal. Despite simply walking through the portal in Hekapoo's forge, she was practically hurled out of it into Marco's room, landing face-first on the ground. As she sat up, grumbling to herself, she heard Marco exit the portal behind her. She turned and looked at him, letting out a disappointed "Oh."

Marco had turned back into his fourteen year old self, though strangely enough none of his clothes changed. He looked down at his new-old body in shock.

"No! My hot bod! Where did it go?!" Marco demanded, staring at his somewhat chubby stomach. If anything, he actually looked more out of shape now than when he first left earth. Star responded by poking him in the belly, much to Marco's embarrassment as he quickly covered himself with his, now too large, biker jacket.

"I guess you're back on Earth's timeline now." Star said, giggling slightly. It was probably for the best that he changed back, it would have been pretty hard to explain to everyone why he suddenly looked like an olympic bodybuilder. Though she was a little upset that he lost his abs, she was also glad that Marco looked like how she remembered him. "But look on the bright side. You still have your bald spot."

"Seriously?! That's the thing that stayed the same?! How does this even begin to make sense!?" Marco asked in annoyance. Why on earth would the bald spot stay, while the rest of his body, including his scar and tattoo, vanished? His train of though was interrupted by another portal opening and Hekapoo sticking her head through it, laughing.

"You got the mark of Hekapoo, son!" she said, "Also, I'm going to be checking in on you every now and then. Arikado would be ticked if I didn't."

"I'm sure that's the only reason." Marco responded slyly.

"With that scrawny bod, yeah it is." Hekapoo said with a smug grin. She then ducked back into the portal which closed behind her. Marco looked back down at his body with annoyance. Star placed a hand on his shoulder.

"Hey, who cares if you're fourteen again? That just means we have more time to go on adventures together. Especially now that you have your own scissors." She tried to reassure him. Marco glanced at his new dimensional scissors.

"Yeah, I guess you're right." Marco admitted.

"Of course I am. Now I'm gonna go make us some nachos." Star said as she exited the room, only to immediately poke her head back into the doorframe, "By the way, who's Arkeedoo?"

"Arikado." Marco corrected, "He's just a guy I met in Hekapoo's dimension. Pretty sure he works with Hekapoo."

"Huh, never heard of him." Star said. With that she left the room once more and headed down to the kitchen to attempt to cook. Star doubted that Marco had any nachos while in Hekapoo's dimension, she'd never even heard of them before coming to earth, so she figured it would be a good way to welcome him back to earth. She was actually a little worried about Marco, why would he not want to come home? Sure, a lot can happen in sixteen years, but he seemed sad about not returning. Like he wanted to, but couldn't for some reason. What could have happened that would make him feel like he couldn't come back? As much as she wanted to ask him about it, she decided to let him tell her when he was ready. It seemed pretty bad from the way he talked about it, and Star didn't want to upset Marco.

As Star reached the kitchen she made sure to grab a cookbook. She learned recently that she wasn't as good of a cook as she used to think, and she didn't want Marco's first experience back on earth to be him getting sick from her cooking.

Marco looked around the room, his room he reminded himself. There was little familiarity here, just a vague sense of nostalgia. This was where he had lived since he was a baby, he grew up here, so why did it feel so foreign? Why did it feel like this wasn't where he belonged?

'It's because I haven't been here in so long.' Marco thought to himself, 'Yes, that's it, nothing more."

Marco told himself this was where he belonged, nowhere else. As he moved about his room, he recognised various objects, and remembered parts of life that he hadn't thought about in years. It felt encouraging, it reminded him of who he was before his visit to Hekapoo's dimension. Before his visit to the Castle.

Marco stopped in front of his desk, sitting on top of it was a laptop. He hadn't seen one in ages, as he stared at the QWERTY keyboard he realised that it had been awhile since he'd last seen something written in English. Hekapoo had clearly tried to write his name in English on the scissors she'd given him, but she'd screwed up slightly. Not that he was complaining, the fact that she even tried was touching. Turning his attention back the laptop, he tapped the touchpad, hoping that was how you turned it on. The screen light up, and Marco was glad that he hadn't forgotten something as basic as turning on a computer. His relief was short lived though, as he starred at the login screen.

"Password?" He spoke aloud. He wracked his brain to try and remember what it might have been. In the end, he couldn't think of anything, and admitted that fact to the room, "I don't remember my password."

'It's not important. People forgot things like that all the time.' He reassured himself. Marco walked over to his bed and sat down on it. Looking to his left, he saw a half-eaten hamburger sitting on the bed. He must have been eating it before he was dragged into Hekapoo's dimension. He picked it up and took a bite, finding that it was still warm. Little to no time had passed on earth while he was gone. Marco took a deep breath as that realisation sank in.

That was good thing. It meant he could just go back to his old life, and pretend that nothing had changed. He could go back to being Marco Diaz, safe kid. He chuckled softly at the thought, he used to hate that moniker. But now, he was glad to have it back. He just hoped he hadn't made a mistake coming back.

His thoughts were interrupted by a series of barks and yips. The laser puppies ran up to Marco carrying their leashes in their mouths. They seemed so excited and happy to see him, even though he hadn't been gone that long from their perspective. Marco smiled at them, and picked up their leashes.

"All right. Let's go for a walk." He told them, walking out of the room with the puppies following along behind him.

'I didn't make a mistake coming back.' Marco decided, 'This is where I belong, because I am Marco Diaz. And I will never be Dracula.'

In case it wasn't obvious, this story is going to be using elements from Aria of Sorrow, with Marco filling the role of Soma Cruz. Exactly what happened in Hekapoo's dimension is mostly just going to be hinted at for the time being, though if you played Aria of Sorrow you probably have some idea of what went down. But, I will warn you that Marco's experience was different from Soma's in certain areas. Also, I'm probably going to ignore most of the plot and lore from Dawn of Sorrow, since I felt like that game kind of ruined the story of Aria.

I'm sorry that this chapter was mostly a retread of 'Running with Scissors', but I felt it was important to go over this scene since it did change in this story. Next chapter will be something wholly original.
