I got the idea at random and a way to make the story work. There have been even weirder stuff happen in other SVTFOE fanfictions and Naruo fanfictions, so I see no reason this can't happen.

I know no one asked yet and I know Season 3 is over but this takes place from Marco after he left back to Earth after The Battle for Mewni. I wondered what an alternate start to Season 3 would be like and this suddenly popped in my head.

Mewni/Butterfly Castle

Marco was packing a duffel bag filled with what he brought along and reminders of his time on Mewni. Corn, his grass skirt he got from King River, Mewni Corn Soap, a Goblin Dog, a spare T-shirt, and a Love Sentence toothbrush. He was currently sporting his white "I'M A HOT DAWG" T-shirt with a picture of a goblin on the side of a hot dog he got from the incident with Roy's V.I.P. line, slightly baggy black pants, and his brown and white tennis shoes. As Marco looks into the bag of his only souvenirs of Mewni and Star.

Star

He looked away from the bag in sadness. He is going to say good bye to his best friend. Well, yes, he does have Dimensional Scissors and can come back anytime, but would King and Queen Butterfly let him? They obviously appreciate what he did for their daughter, but that's just it. What did he do for her?

She had done far more for him than he ever did for her. After all, she is the whole reason his life changed so much and got the courage to ask Jackie out.

Marco stopped at that thought.

Why did she help him get together with Jackie if she had a crush on him? "She wanted me to be happy." That does sound like Star, but why did she only tell him when she was leaving forever? "Guess she thought she had nothing to lose." That didn't make it okay, but is understandable.

Marco grabbed his bag and took a deep breath to calm his thoughts. He was asking questions that are screwing with his head. He needs to calm down. Technically this was goodbye, and he didn't want to make it even harder for both him and Star.

Marco looked down while walking out of the room when he was grabbed by the arms and upwards he heard a familiar faces of Mime Girl, Foolduke, and the Songstrel Rubariot. "Uh, hey guys." He said feeling awkward about the angle.

Rubariot spoke first. "We're going to miss you dude." He said in a soft voice.

"Come on Marco, can't you stay a little longer?" Foolduke asked kindly.

Marco smiled softly. "Love too. But Earth's calling."

Rubariot responded. "Alright then. Catch you on the flip Marco." He said as they threw him at an angle for him to flip. Due to Marco's experience with this kind of thing he reflexively flipped and landed on his feet on the large stone stair rail and slid to the bottom where he saw the wide eyed River, blank faced Moon, and down looking Star who had her hands behind her back.

"Well, uh, I guess this is goodbye." Marco said with the sadness returning.

River put both hands on Marco's shoulders. "And what a pleasure it's been." Marco smiled before River pulled his face into his beard. "This place won't be the same without you my lad. Eh, but, before you go. There's something I want to give you for all you've done for our kingdom." He said releasing the teenage Latino from his hug. "Squire!" He shouted as a skinny young man dressed in servant clothes showed up with a small blue and gold chest with one blue star on each side of a golden crown symbol.

Marco looked at it in slight excitement and confusion when River opened it and pulled out a turquoise colored cape with a light blue "M" on the back. "Ta-da!" He said as he put on Marco, to which he turned around a bit checking out. "Woah cool." He said in amazement.

"Ha ha! You're like a real live knight now look at you my boy. In fact, if you ever want to be a knight one day give me a call." River said as Marco lit up.

"Wow! Thanks River!" Marco said excitedly but couldn't help a bit off. He lost the cheerfulness and excitement and dawned a look of confusion. "Wait. Doesn't being a knight take a lot of training and practice?" Marco asked as River gained a surprised look and slight nervousness.

Marco looked at his cape removed it and handed it back to River who looked even more shocked than before. "I appreciate the thought River, but I have Dimensional Scissors. I can come back and learn to be a real knight through trial and effort if you would let me one day." He said that last part nervously afraid he offended the King.

River looked from Marco to the cape he handed back in silence for a few moments before he smiled and took the cape from him. "Like a true warrior wanting to prove himself through the toughest of trials. Well said my boy." Said River as he affectionately slapped Marco's back as said boy winced but smiled brightly at the King's praise.

River then backed away allowing Moon to walk towards him with a gentle smile on her face and gave her own goodbye. "Take care of yourself back on Earth." She said as she kissed his forehead.

Marco smiled softly never really seeing this side of the normally stoic Butterfly monarch. "Thanks." He said in a soft voice but laced with an unfathomable amount of appreciation. Moon smiled at him then gave a look to her daughter that he could have sworn was sly look. Star had a blank look that quickly turned sad when her and Marco got closer.

"I guess this is it." Marco said sadly.

Star responded in an obviously fake enthusiastic voice. "Well, bye." She said holding out her hand in a waving motion. Marco then cut a portal to Earth with his Dimensional Scissors. He looked back briefly at Star before grabbing his bag and began to walk through the portal.

Star gained a sad and pained look watching him leave. She then reached out, grabbed him, and pulled him back through. "Wait! Marco!" She said holding him by the shoulders in front of her face. "I need a longer goodbye than that" She said desperately.

Marco then let a sad smile make its way onto his face. "Me too." She then pulled him into a tight hug and Marco could feel her tears through his shirt on his shoulder. He the placed both hands on her back and returned the hug with a heavy heart. She then released the hug.

"Well, bye. Again." Star said looking down.

"Bye." Marco said as he tried to walk to the portal but Star accidentally walked in his way.

"Oh, your going to the p-portal, right? Okay." She said but they kept walking into each other. While this goes down River and Moon share a knowing glance.

They eventually get Marco with his back to the portal and Star standing in front of him. "Well, bye." Marco said

"Bye." Star responded.

"Bye." Marco said again.

"Okay Marco." Star said with a half lidded look.

Marco awkwardly laughed. "Right." He picks up his bag and walks through the portal. Star crosses her arms and looks away sadly, then Marco sticks his head back out. "Oh and can you let me know if you see my hoodie anywhere?"

Star looks back at him. "I told you I haven't seen it. But if I find it I will send it to you." She said with a smile and hands on her hips.

"Okay, cool." He pauses and looks to the side with a strange look on his face. "Thanks. Okay. Bye." He said as he disappears into the portal and it closes.

Star just stands there gazing sadly at where the portal vanished from. Moon and River look at her with sad gazes. She looks at them and says. "I'm, going to my room." Star spoke as she started up the stairs.

Earth/Echo Creek Diaz Household

Marco walks through the portal into the living where both his parents jump up from the couch and hug him tightly.

"Are you alright mijo? How is Star? Is everything okay? Have you eaten?" His dad asking him rapid fire questions.

"Raphael calm down lets let Marco explain what happened. Can you do that sweety?" Angie calmed her husband and asked Marco. She was the more in charge parent when it came to stuff like this.

Marco takes a deep breath and begins from when he brought the Sugar Seeds Cereal to Mewni and found River in a trashed castle.

Meanwhile in a dimension one over from Earth

"You sure this will work?" Said a missing ninja from the Hidden Leaf. The man he was speaking to is a jonin level ninja but never belonged to a village. He was one of the 21st century humans from Earth. He had gotten here after his friend had stolen a pair of Dimensional Scissors after killing the previous owner. So far the person who crafted the scissors didn't suspect anything, yet.

After they became friends and read some ancient scrolls they found HIS tomb. They kidnapped some poor sap walking down the road and planned to use him as the sacrifice required for the Impure Reincarnation Jutsu. Thats how they got here today.

"Come on man. After all the research and all the effort you want to go back, now? Think about it, with him we can rule all the dimensions especially this one!" He said to his Elemental Nation native friend.

He scratched his head. "That sounds great and all but I have a bad feeling about this. What if that missing and teared apart bits of the scroll was important?" He said still unsure of if this would turn out well.

"Dude, come on have some faith besides I can't use chakra like you can so you do the hand seals. Besides this way if something goes wrong you can just release the jutsu right?" He said already knowing he won him over.

"*Sigh* Fine. But if this goes wrong I blame you." He said pointing at him to which he raised up his hands in defense. He then turned his attention to the gagged and bound stranger begging to be let free but only came out in muffled cries. "Sorry, but we need you for this." He then started flashing through the required hand signs.

After it was activated the man then was covered in paper and reformed into something else. When the figure took full shape it stepped out of the coffin and looked at those who reincarnated him. "What is this all about I was enjoying a drink in the afterlife with a friend." He spoke roughly and glared through his narrowed eyes.

The Earth dwelling human spoke out in excitement. "It worked! Now with him under our control we can rule!" He shouted while the reincarnated man had a blank look on his cracked face.

"You both do realize you have to have more chakra and better control over it in order to control a reincarnation right?" He asked rhetorically. His theory proven when both men froze up on the spot with horrified looks on their faces.

"Quick! Release the jutsu!" The Earth Native shouted at his Elemental Native friend who quickly made a hand sign.

"Relea-!" Before he even finished the word however, the reincarnation looked him in the eyes crimson red eyes glowing stopping him from finishing even a thought. He then stabbed the Earth Native with a kunai in the juggler.

As he bled out the reincarnate looked into his eyes with the Sharingan. "Earth huh? I thought your signature was a bit off." He looked back at the one who reincarnated him which he had under his control.

He walked over to him and took the Dimensional Scissors from his pocket. "It's been thirteen centuries since I seen one of these. I wonder how Earth has been? The first people to awaken chakra all got it from The Sage of Six Paths, that much is known. However what most don't realize is that we all came from Earth originally. After several humans abused Dimensional Scissors to get to this reality Hekapoo then started making people earn them as so not to through off the balance. This however left Earth isolated as no 'normal human' can really do any good in her trial much less have the drive to." He finished his history lesson and looked at the dazed missing ninja.

"You know what? Maybe I should visit Earth. It would be nice. Who knows, there could be some chakra users there." He then cut a rift to Earth with them and walk through.

Earth/Border to Echo Creek

As he stepped out of the portal he noticed the buildings and technology inside the town. The humans in this dimension have certainly advanced. He looked back at the man under his control. "As long as he is alive and doesn't release the justsu, I won't return to the afterlife." He muttered to himself. He then looked out at the town. "Go back to the cave and come back in 3 hours. I'm going to have a look around." He said handing the scissors to the mind controlled man then began moving superhuman speeds past anyone before they could see him he was standing on top of the hill of Echo Creak Park.

He didn't have to worry about people here because it was closed for destruction for some reason. He could have sworn the construction workers said something about a crazy purple haired donut dumpster looter. Anyway he didn't expect any results for sensing chakra signatures and just kinda wanted to see the sights a bit before heading back to the afterlife.

He sent out a pulse of chakra and just stood there bored, then he felt something.

His eyes snapped open.

He looked in the direction he felt the pulse and rushed to it. How did one of his clan end up here and with no other signatures around?

Diaz Household

Marco just finished answering his parents questions about everything that happened on Mewni and was texting Jackie an apology for not answering her messages or calls. Apparently in some dimensions you get more bars or no bars. It was extremely inconsistent, no wonder everyone uses mirror phones.

Before Marco could continue his thoughts on Cellular Service across the dimensions, he felt something that made him sit straight up. He couldn't explain what it was, it was a brief... pulse... a powerful center sending it out that is for sure.

Something suddenly appeared in his room in a swirl of leaves. A tall man with long black hair, red eyes with three tomoes in each eye and for some reason black behind it and cracks in his face, he wore red plated armor of some sort over a black cloak that kind of reminded him of a samurai, thick black gloves, black pants with the bottom tucked in white wraps, and open black Japanese sandals. "Hello there young one my name is Madara Uchiha and I think we should have a discussion."

Marco froze. What was he supposed to do? This guy showed up out of no where appearing faster than his eye could track and wants to have a talk with him. This Madara could have killed him if he wanted to before he even knew what was happening. So wanting him dead immediately was out, so he must want something.

Marco gulped. He doesn't know what this guy is capable of, so best to play along for now. Marco nodded slightly in agreement as to not upset him.

Madara raised an eyebrow at his behavior this young teen is a member of his clan and living here? "Probably a descendant from one on Earth. That would explain the brown hair and brown eyes instead of black." He concluded. Madara then looked the boy in the eyes. "You felt me when I sent that pulse." It was a statement more than a question,

Marco nodded. "Then you really do have access to chakra." Madara responded in thought. Marco looked at him confused.

"Um, I never actually meditated so..." Marco trailed off. Madara brought a hand to his head.

"I don't mean that Buddhist thing. This may take longer than I thought." Madara corrected a little annoyed. He sighed. "Guess I should start with an explanation on chakra, the elemental releases, its uses, etc." Madara looked at Marco. "Alright, I guess I'll start by telling you what chakra is in my world." Marco timidly nodded.

Madara proceeded to tell the teen about chakra and basic history, like his battle with Hashirama (to which Marco got wide eyed and slack jawed hearing how they tore mountains apart in their battle and the crazy skills they unleashed.) The closest thing Marco seen to that was Star blasting Toffee into oblivion. Madara briefly stopped his explanation to hear about it, he commented how her blast may not be as powerful as some of his justsu but the spells use did kill an immortal and maybe that was the whole point. It was meant to kill things that aren't killed through normal circumstances rather than raw destructive power. (Remember her Turbo Nuclear Butterfly Blast?)

Marco was genuinely interested in this subject. Humans manipulating the elements, defying the logic of reality (and gravity), and bloodlines to enhance those abilities or give new ones. Marco couldn't help but ask the question that has been on his mind through most the lesson. "Um, Madara, sir? All of that is really cool but what does that have to do with me and why tell me all of this?" Marco asked the million dollar question.

Madara then grinned. "Perceptive. I like that. Well I am not going to sugar coat it for you, you are a really long descendant of mine. An Uchiha. I sensed it in that pulse of chakra I sent out. You have a similar signature to all other Uchiha, which is surprising considering that you are probably a lower offspring. Meaning one of your grandparents or great grandparents were originally born in The Elemental Nations." He answered honestly.

To say Marco was shocked would be an understatement. This ancient powerful man was his ancestor? Then again if he is able to chakra that would explain how a 14 year old punched through the chest of a lizard man and fought all those monsters on a normal basis. So he had unknowingly awakened his chakra and Madara just happened to show up to explain all of this now? What are the chances? Most likely astronomical, but so was meeting Star.

Madara spoke again. "Look because it would be a waste of potential I am willing to train you. However if you don't want to learn about this I can wipe your memory of me, I will leave for good into the afterlife, and you never have to know this moment even happened. Or keep the memories of what I told you but deny my training that is also fine. I will not force you, but if you want to learn to be a real Uchiha meet me at the park at 6 AM. Your first test would be to sneak through the construction site. I do hope to see you there. I would hate for such potential go to waste." Madara finished and vanished in a swirl of leaves leaving the boy alone in his room once again.

Marco stared at the ceiling blankly. These past few hours have been the most heart tugging and strangest of his life. He looked over to his alarm clock. 3 in the afternoon. Marco then heard a noise at his window and got up to check it out. He didn't see anything until a blue star shaped box hit him in the face.

Marco looked down at it and opened it revealing it to be his hoodie. He smiled and put it on then he noticed something peculiar. "It kinda smells like Star." He said to himself. He looked up for a second before sniffing it again.

7 PM Echo Creek Pier

After what happened early that day Marco decided it would probably be nice to see his other friends and girlfriend. So he invited them to the pier to tell them what happened on Mewni, but decided not to mention his ancestor from centuries ago showing up to have a chat.

Which reminded him, how is he here now if he is centuries old? He should ask about that later.

With him was Jackie, Alfonzo, Furgesion, Janna, and Starfan13. All of them were sitting at a table in front of a coffee shop discussing what occurred on Mewni.

"Is Star okay?! Is she hurt?! Did Starco happen?!" Were the shouts of Starfan13 in such rapid succession he could only understand a handful of what she was saying.

"What was all of that stuff about at the party?" Asked a confused Alfonzo.

"Yeah. Star just shouted she had a crush on you and had to leave Earth forever. That doesn't exactly mean something good." Furgesion said with an eyebrow raised.

"Did you leave an ere before you left?" Was the classic inappropriate question Janna asked which caused everyone at the table to turn bright red. Marco glared at her with the red never leaving his face.

"N-No! We're fourteen and have n-never done anything like that J-Janna!" Marco replied hotly with a stutter. During all of this Jackie had been silent and a strange look on her face. Marco took notice first.

"Jackie are you okay?" He asked in honest concern. Jackie looked at him and smiled gently. She thinks it's sweet of him to worry about her even calling her to let her know beforehand where he went and apologized for not responding sooner.

"I'm fine dude, really." She responded putting up her classic cool front. This seemed to delude Starfan13, Alfonzo and Furgasion, but Janna and Marco knew better having been around her longer. Janna and her are best friends after all. Jackie figured out how to see through Marco, but he picked up some things too. Marco decided to talk to her about it after the group split up.

"Anyway, Star killed Toffee with some powerful golden blast from her wand and in a golden butterfly form. Afterwards I spent the night resting up after Toffee threw into a wall so hard it left cracks, so I had a bit of pain in my ribs and back after that and-" Marco was interrupted by Janna.

"Wait, wait. The lizard guy threw you into a wall so hard it left cracks? Your spine should have broken or at least your ribs, but you just walk it off saying it was just sore?!" Janna said in a confused tone as if the whole thing was ludicrous.

Looking back Marco had to admit he didn't even think about that. Then his mind wondered back to his talk with Madara and how he explained that chakra makes the body stronger and more durable, which explains a lot of his injuries being better than they reasonably should be now that he thought about it.

"I guess I'm just durable. I don't really have an explanation for it." Marco shrugged.

He is lying through his teeth, but in this case if Madara does something he can't risk their safety. It's best to keep it a secret for now.

Janna looked at him as if seeing through his lie, but didn't say anything. She would find out eventually anyway. After everyone asked about Star and the fight they noticed it was getting late so everyone started heading home. The only ones left were Marco, Jackie, and Janna. Janna said her parents work a lot so she usually stays out late most of the time. Marco couldn't tell which part could be the truth or a lie, she was very good at it so its hard to tell.

Marco stopped Jackie from walking away by grabbing her hand. She looked back at him and noticed Janna sitting at the table on her phone occasionally taking peeks at them. She turned her attention back to her boyfriend who looked concerned.

"Jackie are you sure you're okay?" He asked again. Jackie sighed knowing he figured her out. She looked at him again this time with a gaze filled with sadness and uncertainty. Marco and Janna both were taken aback by the expression neither had ever seen on her face before.

"I... well... it's just... I just don't know what to think right now." Jackie said looking down. The look on Marco's face signaled her to elaborate. "Star confessed to you, left for Mewni forever, died for a bit, then came back and wiped out Toffee, and then you two said goodbye. I thought that you might realize how interesting and amazing she is and how... boring I am in comparison." Marco looked shocked but she continued. "She is this magical princess from another dimension with a cheery personality, fun adventures, beautiful looks, and so much more interesting then me." At this point tears started to form in the corner of her eyes. "I never showed it but I envy her. She is everything I would want to be. I never hated her though, she is just better than me in every way and-"

Jackie was cut off by Marco doing something that shocked Janna and Jackie both. He kissed her on the lips. It's always Jackie who starts their kisses and yet here is the safe kid now taking the initiative.

Jackie could feel the passion he put into it and how overwhelming it was. It took a few seconds, but she eventually closed her eyes and returned the kiss with tear streaks running down her face.

After a few more moments they broke the kiss and Marco wiped away her tears with his thumbs. She put up a hand and held his to her cheek which now was sporting a pink blush.

"Jackie listen, I won't lie to you. I don't know how I feel about Star anymore. She was my best friend and after she confessed it caught me off guard. I'm confused with how I feel about this and me and her will have to talk about this eventually, but I do know one thing that I know for sure. I love you. I'm not going to abandon you to run off and be the biggest douche bag in the infinite dimensions by leaving an amazing, funny, gorgeous, caring, and kind heated girl in tears." Marco said with complete conviction and no doubt in his tone or face.

If Jackie and Janna weren't shocked enough they sure were now. While Jackie's blush had become as red as Marco's hoodie. Marco had just said he loved her with no hesitation. Loved, not liked. Jackie felt her heart warm at his deceleration along with every compliment he gave her.

Jackie spoke barely above a whisper. "Do you really mean that?" She said with new tears of joy replacing the previous tears of sadness and self-doubt.

Marco nodded. "I really do." He answered.

The warmth in Jackie's heart just increased a hundred fold. No one had ever spoke to her like this before or showed his much care towards her. It was official, Marco is definitely the guy she loved. She pulled him into a hug by bringing her arms around his neck and pulling him down a bit. "I love you to." She said back finally.

Both Jackie and Marco stayed like that for a bit until they heard the voice of their favorite trouble maker.

"Aaaand posted!" Janna said as she put her phone away and the couple looked at her confused and suspicious. "You sure have a way with words Diaz. I thought other guys on the Web could learn a thing or two from you so I posted the first part of your speech on an account I hacked. So no worries about a video or something. Even I have lines I won't cross." Janna finished shrugging nonchalantly.

Jackie smiled. "Thanks Janna. I appreciate you keeping this between us." She thanked her beanie headed friend who just waved her off with a smile.

Marco also gave his thanks before saying he had to rush home before his parents think he's off schedule. That caused Janna to wave goodbye. "Okay Safe Kid!" She said loudly causing him to cast an unamused look to her as she laughed it off.

When Marco disappeared from sight Janna turned to Jackie. "I know he lied about the having no clue about surviving the wall thing. He is hiding something and I will find out like always." She said getting a suspicious look on her face while Jackie looked confused.

"How can you be sure?" She asked.

Janna looked back at her I've known him since Kindergarten. I know what makes him tick and everything else, especially when he is lying." She answered evenly.

"Okay, but why lie? He wouldn't lie without good reason. Then what does he gain from this?" Jackie asked out loud. Janna just looked on where Marco left. She would have to look into this.

Okay first chapter done! Hope you all liked it and as always you have any suggestions for the story put it in the reviews and I'll get back to you as soon as possible.

And if anyone is wondering why I picked Madara, well I thought having the Sharingan just fit Marco better and who better to teach him than the most powerful Uchiha (besides Sasuke) to teach him.

Madara has also seen a great many jutsu in the 4th Great Shinobi war with his Sharingan and could teach it to Marco. I know he never used them, but Kakashi copied the Rasengan and used it once during Naruto's training but never in another battle. So there is no reason to believe Madara can't at least tell Marco how it works.

Also the chakra thing is a good reason to believe how Marco took so many hits that would incapacitate him or doing damage that could only be explained through a boost in power. (Another good reason could be Monster Arm's residue coursing through Marco's body.)

Okay anything else please let me know.
