A/N: So with Rise of Skywalker and the season finale of Mandalorian out I figured it would be cool to do a Star Wars AU. Then I remembered there's already a great Star Wars/SVTFOE crossover out there called Star (Wars) vs The Forces of Evil by EDD17SP. Highly recommend checking it out, they're a way better writer than I could ever hope to be and what's published of the story so far is amazing. Anyway, this one is going to be something a little different but still with that Star Wars theme so I hope you enjoy!

Chapter 6: Why Star shouldn't be allowed to have a lightsaber

Even after a year of having Star in his life, it still amazed Marco how little she knew of technology sometimes. It seemed like possessing magic had frozen Mewni in what would be the equivalent of medieval Europe here on earth. He fondly recalled the day he met Star and she had no idea what a light switch was or how a water fountain worked. It was a little strange because she had been to all these amazing dimensions with even crazier technology than earth but Marco ultimately chalked that up to the difference between visiting a place and actually living there full-time. So one day when Star saw a trailer for the latest Star Wars movie coming out, Marco hadn't been at all surprised that she was insisting on seeing it. Now, being a true gentleman and a devoted fan of the franchise, Marco had seen it as his duty to educate Star on the proper order to watch the movies in, quieting any protests she had about not seeing the new one in theaters immediately with the promise of a weekend movie marathon of the original trilogy with double nachos. As Marco had anticipated, Star had been fascinated by the sci-fi technology and the sense of wonder it had created in so many others. What he hadn't anticipated was how obsessed she would become with it.

Case in point, the following Monday Marco arrived home after being held up in school to find his living room had been covered in a sheet of snow. Tiny laser bolts were firing everywhere and destroying the house as miniaturized AT-AT's battled snow speeders in a reenactment of the battle of Hoth. Star herself was sitting on his couch, which had been remodeled to look like the rebel shield generator, drinking a cup of hot chocolate and watching with rapt attention. It had taken Marco walking right up to her and booping her on the nose to break her out of the trance. The next day Ludo had come for the wand, as per usual. He and Star had jumped into the fray with their normal enthusiasm and while Marco engaged with his usual karate, Star's spells changed dramatically. Her narwhal blast had been replaced by a wampa blast and warnicorn stampede had been changed to a wookie stampede! Suffice to say Ludo and his minions had been absolutely terrified and had fled even faster than usual. By the weekend Star was insisting on seeing the rest of the movies, the multiple tv series, anything she could get her hands on. When she started referring to her spells as force powers and her spell book as a holocron, Marco knew he'd lost her completely. Again, he didn't realize quite to what depths.

It was around week three of the Star Wars obsession and Marco had been out for the day running errands. Not seeing his parents or his bestie around he'd decided to check in on Star, knocking on the door hesitantly. "Star, you in there? I'm back from the store. I figured we could go dimension hopping if you're up for it?" Getting no reply and seeing only darkness in front of him Marco ventured just inside the doorway when suddenly a loud hissing sound emerged followed by the unmistakable sound of a metal plate slamming shut. The room suddenly illuminated and standing in front of him was Star… or at least he thought it was Star. The girl standing before him was in a skintight black suit complete with a flowing black cape and full-face mask. "S… Star. Is that you?" Marco got out nervously.

The voice that answered back sounded like vaguely like Star's, but deeper and more threatening. "Star Butterfly was weak, I destroyed her. You are standing in the presence of Darth Astrum. Now Jedi, you will give yourself to the dark side or you will meet you friend's fate."

Marco was beyond confused. "Jedi? C'mon Star I'm not a Jedi. It's me, Marco, remember?" Marco trailed off as Star leveled her wand at him and he heard the classic "radiant shadow transform" followed by momentary blindness. When he'd recovered his senses, Marco found his classic hoodie and slacks had been replaced by the cream-colored robe of a Jedi. Star proceeded to place the wand on her belt.

"Now then Marco Diaz, Jedi Knight. If you will not join me then draw your saber at least. Otherwise this will be no contest."

"Star I don't have a lightsaber!" Marco frantically patted himself down to show he had no weapon before his hand slid over a metallic cylinder on his belt. Pulling it off Marco's eyes grew wide. She couldn't have…. He decided to thumb the activation switch and the oh so familiar snap-hiss followed by the emergence of an emerald green blade confirmed it. Star had conjured him a lightsaber. Oh sweet merciful lord Star wanted to fight him! "Now Star" he began hesitantly. "You don't want to do this, don't you think this is going too far?"

Star could only chuckle. "I keep telling you, your friend Star is gone. Now then Jedi, prepare yourself!" Star thumbed her own activation switch but instead of a typical sword the end of her saber appeared as a… "A battle-axe Star! Seriously?!" Marco exclaimed. "How the heck is that fair?!"

"It's not supposed to be fair Jedi scum, it's supposed to be your death!" And with that Star leaped at him, Marco barely dodging as her axe buried itself in the floor.

"Star I'm serious! Cut it out!" Marco barely managed to deflect the next few blows, his arms rattling with each contact. Another dodge saved him as Star's saber imbedded itself in her bedspread, instantly setting fire to the comforter. Ok Marco, he thought to himself. You're facing an insanely strong magical princess with a glowing laser-axe that can cut you in two and is either really taking a practical joke wayyyyy too far or is actually hellbent on ruling the galaxy as a mistress of evil and sees killing you as the first step. How do I get out of this? Maybe he could appeal to her love of the series? Worth a shot.

"Star, you don't want to do this. There is still good in you, I can feel the conflict."

"There is no conflict" Star monotonely stated as she reduced the table Marco had been hiding behind to kindling.

"Uhhh…. If you strike me down I shall become more powerful that you could possibly imagine. Wouldn't want that would you?" He was forced to deflect another series of powerful swings in response.

"The dark side is a pathway to many abilities some considered to be unnatural?" That one didn't work either. Marco could feel himself tiring out fast, at this rate he couldn't keep Star at bay for much longer. No sooner had that thought run through his head that Star took a particularly vicious chop at him, knocking Marco's saber out of his hand, deactivating as it rolled across the floor. He found himself on the floor, staring up at Star, her battle-axe at some point having shifted back into a regular lightsaber, poised to strike him down.

"Any last words Jedi?"

Marco closed his eyes and thought. Without opening them he said "Attack of the Clones was by far the best prequel movie." When he felt nothing, Marco cracked open an eye to see the red blade mere inches from his neck and hearing the unmistakable peal of Star's laughter. Opening his eyes full Marco saw Star holding her side with one hand, mask up and tears freely flowing down here face.

"Oh that is a good one Marco! Attack of the Clones! Ha ha ha ha!" She deactivated her lightsaber and continued to giggle uncontrollably.

Marco got up and dusted himself off. "I think you went a little too far with the practical joke on this one Star."

Star had finally gotten herself under control meanwhile. "Yeah… maybe a little. I'm sorry Marco. I just really wanted to have an epic lightsaber battle with you and well, one thing led to another."

"And the fact that your lightsaber was a giant battle-axe?"

Star at least had the courtesy to look sheepish "I'm more used to it than a sword okay?" She tried to brush it off, "besides, it's not like anything too bad happened."

Marco took a look at the destruction of Star's room, including the bedding that was still on fire. He rolled his eyes, "yeah~ tell you what Star, how about we make a rule that form now on, no more lightsaber duels in the house?"

Star pouted "Oh fine." Thinking about it for a second she added, "but can we still use them on Ludo?"

"Oh that's ALL, we're using on Ludo from now on"

"Awww Marco! Hugs!"

And true to Marco's word, from then on Ludo learned to fear the awesome Jedi/Sith duo that was Marco Diaz, Jedi Knight, and Darth Astrum, mistress of the Sith.

A/N: So when trying to pick Star's sith name, I went with a Latin translation. Turns out the two closest were Stella, which seemed too obvious, and Sidus which was a little too close to Sidious for me. Astrum, at least according to google, translates to constellation, immortality, and heaven, which I figured was a good alter ego for everyone's favorite angelic magical princess.

So that's it for this chapter, remember I'm always looking for new stories to add to this so please, if you read this and like my writing, be generous with suggestions. I also want to acknowledge a couple people who have taken the time to review

Starco4everr: Thank you for all the positivity! I'm glad you've been liking them so much!

SugarQueen97: Yeah I've always enjoyed JanTom where Tom both loves Janna and is terrified by her. I figured it plays to her creepy persona and it just seems to work really well. It's an interesting theory on why Star's soul in damned, guess you'll have to wait for Son of Hades Part II to find out. Gracias!

RJWritingInk: I hope that means you liked it haha. If so, great! If not, any suggestions on how to improve?

Shaeril McBrown: Yeah I like it when Marco sings too. Truth be told I borrowed the idea heavily from LordCornwallis' fic "In the Pale Starlight" The way they incorporate piano into the story is fantastic and I was hoping to replicate that at least a little.

Next update sometime soon!
