It had been a few weeks since the trip to Quest Buy, and during this time, Marco had been practicing new moves with his powers. Ever since his fight with the Sentinel Rover, Marco thought about how he was always having difficulty with dealing with enemies that are fast and agile.

If it weren't for my Celestial DNA, Rover could've killed me, Marco thought as he remembered how close Rover came to killing him multiple times. Then there was that Monster Arm debacle the day before. Marco shuddered, while remembering his mental battle with his dark self. Coupled with Buff Frog breaking his arm the day before that, and it was all the incentive he needed to train himself to get stronger. So, Marco spent the last few weeks coming up with a bunch of moves that focus on restraining enemies, especially those that are faster and more agile than him. It was slow going, but he could already see the telltale signs that his muscles were improving. Hopefully, the next time I encounter someone fast and robust, like Rover, I'll be able to beat them without Star's help, Marco said to himself. At that moment, Marco heard Star groan loudly beside him as they were getting ready to head to their next class.

"What's the matter, Star?" Marco asked Star in a worried tone.

"Nothing, it's just that I was supposed to ask Oskar out after the whole Quest Buy thing, but I can't work up the nerve to do so!" Star answered in a frustrated tone as she watched Oskar from a distance as he was chatting up a bunch of girls near his car.

While Marco was busy practicing with his powers, Star was feeling very frustrated. Her plan to ask out Oskar had backfired on her. Though they've been hanging out more in that time, and while she had been getting more and more comfortable around him, she was still too flustered to ask him out. To make matters worse, his new keytar has caused his musical talents to skyrocket. As a result, a lot of girls were starting to show interest in him, and that was making Star incredibly jealous. She could have sworn that she even saw Janna trying to flirt with him. JANNA, of all people.

"I'm sure you'll be able to do it, Star. It would be best if you didn't try to force it," Marco said reassuringly.

"Thanks, Marco, that means a lot," Star said, smiling at her best friend for always being supportive of her.

That's when Marco noticed something on Star's forehead, "Hey Star, I think you got some paint on your face." Star lifts her bangs to reveal a purple heart, she reaches up and then peels the purple heart off. Star immediately got a panicked look on her face before gasping.

"*Gasp* Marco this isn't paint. I think I'm going through Mewberty". Star said the last part in a whisper as more hearts formed around her face. Oh yeah, Mewberty. Star then began to panic as he started to pull her hair over her face as more purple hearts started to appear.

"Weeeeeell, ooooooookay, uh, Mewberty! Heheh, that's... nothing to be ashamed of! We have a similar thing here on Earth!" Marco explained awkwardly.

"DON'T confuse this with your Earth things, Marco! I'm from Mewni!" She said, rather loudly. "Things are going to get weird." She lowered her voice down to a whisper. "You gotta keep me away from boys!" She said, desperately grabbing onto the straps of Marco's backpack. Something tells me this won't be anything like Earth's puberty, Marco thought, judging by the desperate and panicked tone in Star's voice. I wonder if Celestials went through something different as well. Marco made a mental note to ask his dad if Celestials went through puberty or something else. His thoughts were interrupted, though, when he heard Star speak up again.

"Wait a second.." Star said in realization."Marco's a booooyy," She exclaimed, pupils, turning into hearts and tilting her head to the side. Star's face then exploded into more purple hearts.

OK, this is creepy on all kinds of levels. "Hehehehe…" Marco awkwardly laughed as he escaped from Star's grip on his backpack. Star's eyes returned to their natural, blue color as she was not near Marco any more, as he backed away a few steps to get some distance from her.

"When you say things are going to get weird, do you mean typical Star weird or, like, destroy the school weird?" Marco asked, though with how panicked Star was, he had a feeling it would be the latter.

"Destroy the school" Star answered without missing a beat.

Ah, crapbaskets. Well, this should be interesting, Marco thought as he looked at how freaked out his friend was. "That's what I was worried about. OK, Star, forget about the rest of our classes. I need to get you to your room and away from any other boys. Marco then grabbed her by the wrist, making sure to use his sleeve to prevent direct contact with her skin.

Thankfully, most of the classes were still in session, so the hallway wasn't that crowded. As a result, Marco was able to lead Star safely for a few minutes. He could tell that she was trying her hardest not to get distracted, but every random boy that she seemed to come across mad things worse. "Oh no, oh no, oh no… OK, here comes a boy, you got this." She mumbled to herself. "You got this..-" Star made a noise. "-avert your eyes, avert your eyes!" She said while staring at a random guy. She inhaled sharply as a popping noise was made, caused by more hearts appearing on her face.

"Marco, I don't think this is such a good ideaaa-" Star trailed off. Marco couldn't hear her footsteps anymore, so he turned around only to see her closely watching some random dude sipping from the water fountain. Star's eyes were hearts again. Hearts rapidly appeared on her face as she watched.

She put her finger in the way of the stream, and the guy opened his eyes and looked at her, Marco noticed that the hearts had spread to Star's arm that was blocking the stream of water. "My tuuurrnn!" She said in a sing-song voice.

"Woah, OK, let's go!" Marco said, grabbing her wrist again and dragging her away. They didn't make it very far, though, as Star's arm suddenly turned completely purple up to her elbow, covered in hearts, with more hearts shooting out of her fingertips and latching onto the nearest locker.

"Waaaaaahh!" Marco and Star screamed in unison, Marco pointed to her arm as they looked to Star's arm, they looked at each other before looking at her arm again.

"Ahhhhhhhhhhhhhh!" They continued to scream as Marco pulled his hand back, which was now covered in hearts from Star's arm.

Star pulled back, trying to detach her arm from the locker, but only succeeded in opening it and sliding inside. Marco quickly noted that this was NOT her locker.

".. I'm stuck." She said Marco immediately made his way to the locker to help. "Uhh, let me help!" At this, she quickly shut herself in the locker.

"NO!-" She opened the door."-Your little boy hands are part of the problem!" She closed the door after that statement before opening it again and speaking up "No offense Marco" and then closing the door again. Marco then brushed his hand against the sleeve of his hoodie to remove the remaining hearts before answering, "None taken."

"Though isn't there SOME way I can help? Maybe there's something in your book of spells that can stop this, or perhaps we can use your dimensional scissors to get home faster?". Marco suggested

"I lent the scissors to Jackie. She said she wanted to use her hoverboard to go sight-seeing" Star answers, which surprises Marco. "Where is she now, then?" Marco questioned, hoping to find Jackie so he can borrow the scissors from her. "Probably in France. She said she wanted to try boarding down from this giant tower," Star answered.


Paris, France

"Woo-hoo!! This was worth skipping school for!" Jackie shouted into the air as she used her board's anti-gravity features to rail-slide down the Eiffel Tower. Thanks to the secure harness and built-in safety-features, she didn't have to worry about falling off, either.

"I am so thanking Star when I get back tonight," Jackie said as she reached to bottom. Thankfully, no one was around to yell at her. "OK, the Eiffel Tower is done. Next up are the Pyramids!" Jackie said as she used Star's scissors to Cairo.


Darn, I can't possibly call her if she's over there, Marco thought before speaking up again. "OK, then what about your Magic Book of Spells?" Marco asked. Star suddenly got quiet for a bit before speaking up, "I gave it to Janna."

Marco got a horrified look as he thought of everything Janna could do with access to the Spell Book, "Why?! Would you give it to Janna?!? "

"I lost a bet, OK!" Star yelled as she briefly recalls the bet she made with Janna a few days ago.


Flashback

"So, Janna, just to be clear if I can pull this tablecloth without breaking a single thing I get to keep your hat for a week?" Star said as she and Janna stared at multiple dishes stacked on top of each other with a glass on the top in the kitchen table at Marco's house.

"ahuh, but if you do break a single thing, I get to keep your spellbook for a week," Janna said while smirking.

"OK, I got this," Star said as she prepared to pull the tablecloth from underneath the stacked dishes.

"And a one, and a two..."

CRASH*

CRASH*

CRASH*

Flashback Over


It's safe to say that from that day on, Star was banned from the kitchen, though she was curious about how Mr. Diaz was able to replace all the dishes she broke the next day immediately.

Star's mind was immediately brought back to her current situation.

"Do you wanna help me or not?!" Star said in a panicked tone.

"OK! But we gotta talk about that betting thing later!" Marco said while running past the locker to find Janna.


Janna was currently looking through Star's spellbook with a smirk. When she made that bet with Star, she was already sure that she would win, especially with how reckless Star was. Though she had to admit, she did feel bad about getting the dishes at Marco's house destroyed.

"Now where is the history portion here" Ever since Janna learned about the Celestials, she had been obsessed with them, especially when she found out that they were pretty ancient due to them being ageless. Now she was trying to learn as much as she could about them in hopes of meeting one of them in person.

Since the last sighting of the Celestial was over 500 years ago, Janna thought that there might be some information about them in Star's spellbook since it documented the history of Mewni going back hundreds of years. Plus, if she happened to find some cool spells, maybe she could try them out for herself.

I wonder if Mewni worshipped a Celestial in the past? Janna questioned to herself before seeing Marco run up to her.

"Janna! there you are!" Marco said in a panicked tone before kneeling next to Janna and the now open book.

"Woah Marco, what's the rush? Did you land another basketball shot on a moving cart again?" Janna said with a smirk.

"First of all, we agreed never to speak of that, and secondly Star's in trouble, so I need the book," Marco said in a severe tone.

Hearing this, Janna got a worried look before handing the book to Marco. I'll just use it later, Janna thought to herself while standing up, letting Marco use the book while she watched from behind.

"And could you give me back my house keys, please? I'm going to need them later," Marco added.

Drat, Janna silently mouthed as she gave him back his keys. I need to figure out how he does that.

Meanwhile, Star was pulling off the last of the purple hearts from her face and dropping them through the opening in the locker. There were enough to form a small pile outside, though thankfully, they seemed to have stopped appearing "OK, Star, if no one else comes near you and Marco gets back with the book and a solution, you'll be in the clear." Star said in relief as she wiped the sweat from her brow before leaning back into the locker in comfort.

That relief was short-lived, though, as she immediately heard the school bell ring. The sight of so many other boys caused even more hearts to appear on her face."No no no no no no no" Star said while spinning with a panicked look as she tried to get rid of them.

Eventually, the bell stopped ringing, "Huh, that wasn't so bad, " Star said, who was now covered with many purple hearts on her arms and face. However, its remarks like that the universe loves to refute. At that moment, the girl's eyes widened when he heard a guy's voice outside. Despite her mind telling her to keep her eyes shut, she ended up looking outside the locker and saw four buff guys in swim trunks.

"Alright, boys, we're gonna do our warmup out here today, pools been compromised," one of the guys said before speaking up again. "Poop, it was poop, someone pooped in the pool," he said with a severe tone before suddenly becoming enthusiastic "OK! let's get started" before they began warming up

Star couldn't look away as she bent the opening of the locker easily while hearts rapidly started popping off, filling up the locker she was in.


"So Marco, what's wrong with Star exactly?" Janna questioned Marco who was currently going through the book's pages

"She's going through something called Mewberty," Marco answered before groaning in frustration. "Argh! Isn't there something like a glossary in here."

"Did someone say Glossaryk?" The pages flipped fast, shooting out a one foot tall bald blue man wearing a brown bathrobe and had a pinkish purple gem in his forehead. "Greetings, I am sir Glossaryck of Terms in service to the Magical High Commission and the Butterfly Family of Mewni" He then waved his hand above, causing his name to appear in purple letters.

"Now how may I be of service milady" Glossaryck questioned.

"Uh, I'm not a milady," Marco corrected him while Janna snickered at this.

Glossaryck eyes widened as he leaned his head in as if scanning Marco before speaking up. "Well, could've fooled me. Goodbye," Glossaryck said as he raised one of his arms and closed the book.

"Hey, wait!" Marco attempted to open the book, but this time it wouldn't budge! For a moment, Marco considered using his powers to force it open but decided not to when he heard Glossaryk speak from inside the book.

"This book is for magical princesses only, which you are not," Glossaryk said from inside the book.

"It's not for me. It's for Star," Marco reasoned, hoping that this annoying little man would help him.

"Ah, Star Butterfly. What's wrong with her?" Glossaryck said with slight worry in his tone.

"She's going through Mewberty," Marco said.

"Well, I don't normally make exceptions but-" Glossaryck said while opening the book, Marco smiled thinking that this blue man was now going to give him the info he needs.

"Pudding," Glossaryck said while floating close to Marco's face. Marco got a confused look. "I want pudding," Glossaryck said. "That's it? You just want pudding?" Marco questioned skeptically, not believing that all it took was pudding to get this man to talk.

"Uh-huh," Glossaryck nodded. "High schools have excellent pudding!" "I'll be right back," Marco said while walking away to look for a secluded area to create a bunch of pudding, leaving Janna alone with the blue man.

"So you don't happen to know everything about the book, do you?" Janna questioned Glossaryck, who turned around to look at her.

"Yes, but I'm afraid you need to get some pudding like your friend back there if you want my knowledge," Glossaryck said. Janna simply smirked before pulling out a pudding cup from her pocket before speaking, "Would this suffice?"

"Hmm, I think we will get along just fine," Glossaryk said while smiling.


A guy who was listening to his earphones while making drumming gestures with his fingers was making his way towards his locker. When he opens it and looks at the mirror, he fails to notice Star, who was now purple and covered in purple hearts with her pupils now being heart shape as well.

"Boy," Star said in a creepy voice as purple hearts drop from her mouth as she extends her finger towards the guy's face. The moment it made contact Star's heart pupil started expanding while the purple hearts completely covered her face.

The guy looks at the place where Star's face used to be until suddenly two heart-shaped eyes could be seen glowing from within and blinking once. The guy, however, merely shrugged as he closes the locker door.

A few moments later, the locker Star is in suddenly starts growing purple heart vines around while seemingly expanding.


"I'm back!" Marco said while carrying a plate full of pudding cups that he created in the bathroom stall.

He sees Janna, who seemed to be humming to herself with a content smile, which was weird for Marco since most of the time, Janna smiled out of mischievousness. Marco also noticed that Janna was now holding a piece of paper with something scribbled on it. However, he decided to ignore it and proceeded to kneel next to the Spell Book.

"Glossaryck, I have your pudding," Marco said while knocking on the book cover. The book then opens to reveal Glossaryck. Oh my, I expected him to bring only one buuuuut I ain't complaining, Glossaryck thought while eyeing the many pudding cups on the metal plate.

"Ahhhhh..." Glossaryck said while pointing to his mouth, causing Marco to get a confused look before speaking up, "What are you doing?" he said in a confused tone.

"You've got to feed me, of course. Pudding doesn't feed itself, ahhhhhhh," Glossaryk said while opening his mouth full again.

"You're joking, right?" Marco asked, deadpan with Janna snickering again from behind him.

"Hmmm, no, I don't think so," Glossaryk answered. Marco simply groaned as he opened one of the pudding cups before proceeding to use a spoon to feed Glossaryck.

"It's... you got it all over your beard," Marco said with a grossed out look before hearing a clicking sound behind him, when turned around he saw Janna recording him now. "Janna! You better not be recording this!" Janna smirked before showing Marco a picture of his undignified, disgusted face.

"That better not go viral!" Marco said in a panicked tone before hearing Glossaryck speak up.

"So... you said Star is going through *burp* Mewberty," Glossaryck said while munching on the pudding.

"Yeah, how do I make it stop?" Marco questioned as he opened another cup of pudding.

"Well, you can't " Upon hearing this, Marco's eyes widen.

"What?!" Marco yelled when he was about to talk Glossaryck beat him to it.

"But you can help her get through it," Glossaryck added, which made Marco calm down a bit. "How?" Marco said

Before Glossaryck could say anything, Marco heard something drop to the floor. When he turned around, he saw Janna was now lying on the floor unconscious.

"Janna!" Marco yelled in a worried tone before running over to her. Glossaryck then floated to the now unconscious Janna and started observing her.

"What's wrong with her?" Marco asked worriedly

"It has begun," Glossaryk said, Marco was confused at this "What has begun?"

"Look, kid, whenever a Mewman girl goes through Mewberty, they release a special pheromone that renders those of the same gender unconscious while those of the opposite gender are rendered docile when they turn" Glossaryk explained.

"Though I'm curious about something," Glossaryk said as he floated close to Marco and started looking at his body up and down, making him uncomfortable.

"What is that?" Marco said nervously

"You seem to be unaffected by the pheromone, despite there already being a large amount released" True to what he said, when Marco looked around, he saw that the place was enveloped by a purple fog that smells a bit like lavender.

"Tell me, kid, what are you?" Glossaryck said while smiling though it didn't make Marco any less nervous.

"W-what are you talking about? I'm a-a human, obviously," Marco stuttered.

Glossaryck simply narrowed his eyes before speaking up again "Well, kid, if you want to help Star, then I suggest you stop her from getting her hands on a specific boy. No idea who might that be, but she'll most likely go after the one she has a crush on.

Oskar, Marco thought to himself worriedly before hearing Glossaryck speak again.

"Or someone with powerful genetics" Glossaryck said, emphasizing the last part.

"Why?" Marco asked, confused why Star would go after a specific boy.

"Because if she does get her hands on that certain boy, she might never turn back, as the point of Mewberty is to find her a proper mate. It can be someone she already has an emotional connection with or someone who can help give her strong children. Above all, though, she'll be looking for someone who can take care of her when pregnant."

"Wait. What?!" Marco said with a horrified look. Glossaryck just smiled smugly before speaking. "Oh, you know when a male and female do a special dance-"

"Oh my God, No! " Marco's face was red with embarrassment when he realized what Glossaryk was implying.

"You know what, I'm just gonna go look for Star," Marco said as he left, not wanting to hear any more from Glossaryck.

"You have until 3:57 whether or not Star will go back to normal by the way!" Glossaryck says as he takes the leftover pudding and puts them into the book before setting the alarm on his watch to 3:57

He then looked at Marco, who had just turned a corner before thinking to himself; I wonder if he's one of them.


Marco was now headed back to where he left Star, hoping that she had stayed put inside that locker. However, he abruptly stopped when he realized how dangerous the situation indeed was, as made evident by how everyone except for him was out cold. Oh, man. This is bad. If everyone's out cold, then there's no telling what Star could do. That's when it hit Marco: if everyone was out of it, then he could use his powers without worry. Even though he knew how dangerous things were, Marco couldn't help but feel excited at the prospect of letting his skills loose. But first, time for some upgrades. Marco then entered a bathroom stall before, mentally preparing himself to materialize the stuff that he needed.

The fight with Rover had made him realize that he couldn't just rely on creating simple objects like a staff or the like anymore. So as part of his training, Marco had been trying to develop more and more complex objects to gain the mental fortitude to handle his powers. Standing in front of the mirror, Marco closed his eyes, concentrating on what he wanted to make.

First off, he created a gas mask to counteract the pheromones and to disguise himself. Even though Glossaryck said he was unaffected, he refused to take that chance. Also, if Star would remember everything going on, he didn't want her to learn about his powers like this. When he opened his eyes again, he looked in the mirror and saw that it had worked. He was now wearing a helmet with a T-shaped visor, a voice vocabulator, an air filter, and decorated in crimson flames. He had modeled it after the Mandalorian helmets he had seen in Star Wars.

Always did think those helmets were cool. Plus, the jetpacks.

Deciding to go the extra mile, Marco then decked himself out in full Mandalorian armor. Everything was there: the shoulder pauldrons, breastplate, pads, thigh, and shin guards, and gloves. All comfortably resting atop his regular clothes.

Nice. Maybe I should keep this as a Halloween Costume. Too bad I couldn't get the jetpack. He had thought about trying, but he realized it would be too complicated, and he didn't want to burn down the school.

"All right, Diaz. Let's go hunting. Oh, man, my voice sounds cool with this thing on!" The boy couldn't help but squeal in joy at the sound of his voice inside the helmet.

OK. Now I just have to restrain Star until Mewberty is over, Marco thought to himself as he exited the bathroom, setting the alarm on his watch for 3:57 PM.

Young Diaz made his way to where he left Star, but as he got closer, his worst fears seemed to be confirmed. Every girl that he passed by was now unconscious on the floor. As he rounded a corner, what he saw shocked him, the locker where Star had been now had some sort of opened cocoon in its place. It appeared to be made from the purple hearts that Marco had seen on Star. "The hearts must have hardened and formed this thing, like a bug going through a metamorphosis," Marco thought out loud. He then looked around and noticed that the purple mist seems to have covered the entire school. Purple vines with heart leaves could be seen growing all over the place.

"Where are you, Star?" Marco said to himself as he walks down the hallway. As he continued, he looked and saw some of the lockers were missing their doors, with one filled with purple hearts.

When he looked inside, he saw the same teen who was drinking from the water fountain was trapped inside.

"Hey are you alright?" Marco questioned as he removes some of the purple vines.

"Hey, answer m--" When Marco got a more precise look at the guy, he saw that his face had a hypnotized look.

So this is what Glossaryck meant by making them docile, Marco thought as he walks down the hallway continuing his search for Star. Hopefully, when this is all over, they won't remember a thing.

After a few more minutes of walking around the school, Star was nowhere to be found. "Damnit, where could she be?" Marco asked aloud, groaning all the while. All right, Diaz, think. If I were magic, hormone-driven Princess hunting down boys, where would I go?

Marco then remembered what Glossaryck said about Star going after the one she has a crush on.

"Shit! OSKAR!" Marco shouted as he immediately ran towards the parking lot where Oskar was earlier that day

When Marco arrived, he got a horrified look at the sight before him.

Oskar, who now also had a hypnotized look on his face, was being held against his car by some sort of creature.

"Oskar!" Marco yelled on impulse but immediately covered his mouth when he realized what he has done. Ah, crapbaskets.

The creature turned around at the sound, and Marco finally got a good look at what Star had turned into. It was her, but her skin was utterly dark purple, and she had six arms and a pair of shimmering, insect-like wings on her back. Her dress and boots had transformed, being mostly purple now. Her headband had now turned magenta, a pair of antenna with hearts at the end replacing her usual devil horns.

Her now light purple hair was styled, strung up in two pig-tails that seemed to move around, almost as if they were alive. The strangest thing, though, was her eyes. They no longer had any pupils, replaced by giant hearts instead.

"Star!? Is that you?!?" Marco was shocked to see that his best friend was now some sort of boy crazed flying insect creature. Why does this entire thing remind me of some raunchy monster ? Marco immediately pushed such thoughts aside, thinking that despite looking different, this was still his best friend, and he'd be damned if he ran away from her now as he took another step towards Star.

"Star, stop this right now. I know you're not thinking straight, but you have to stop this!" Marco pleaded to Star, hoping that she would listen to him. However, she simply ignored him and went back to pinning Oskar to the car with more purple hearts.

Seeing this, Marco walked closer to her. "Star, will you just listen to me!" Marco yelled as he got closer, but still, Star ignored him while she continued to cover Oskar in more hearts

"I said, STOP!" Marco screamed as he grabbed one of Star's arms, making her face him, using his powers to boost his strength enough to make her face him. At first, Star looked down at her arm and then to Marco, as if she was confused by what was happening. Too late, Marco realized what had happened the last time he had grabbed Star.

"Oh, this is gonna hurt."

Without warning, Star suddenly pinned Marco to a nearby wall shooting the same thread like substance he had seen before, sticking him to the wall before leaving him there and going back to Oskar.

"ALL RIGHT, THAT'S IT! I DIDN'T WANT TO DO THIS, STAR, BUT YOU LEAVE ME NO CHOICE!!" Marco ripped a piece of a nearby locker door and turned it into a homemade knife, cutting him free from the threads before turning into bubbles so that no one could hurt themselves with it.

Looking at Star, who was now dangerously close to Oskar, Marco decided to try out something he had been testing after seeing in an anime. Pressing the palms of his hands together before slamming them onto the ground, Marco conjured two giant hands out of the Earth to grab Star, holding her tightly and keeping her away from Oskar.

Star turned around, seeing the strangely familiar boy in armor, and realized that somehow, he was responsible for the hands that had her trapped.

"Sorry, Star, but I can't let you do this," Marco said while looking at Star, who had a surprised look on her face. What little parts of her mind that were still conscious didn't think any of these beings could threaten her like this. While this should have worried her, though, she felt the opposite: she felt excited.

"Booyyy??" Star said in a creepy tone before grinning widely. Without warning, Star broke free from the hands, shattering them and sending debris everywhere, before flying towards Marco at high speed.

"Woah!" Marco sidestepped Star dodging her assault. Star then aimed her six hands shooting the same substance from earlier; however, Marco transformed his gloves into steel blades, ripping the thread to pieces before it could make contact.

Star suddenly gained a predatory look at this sight, grinning widely and making Marco uncomfortable, primarily since the look was directed towards him "Uh Star?" Marco said nervously.

"Boooy," Star said this time, this time with her voice taking on a dreamy/creepy tone. Oh, crud! Before Marco could think of anything else, though, Star charged at him again, this time faster than before.

Thankfully, due to his Celestial nervous system, Marco was able to process information many times faster than ordinary people. As a result, Marco was able to immediately transform his legs into frog legs, allowing him to leap over Star. Before she had a chance to react, Marco followed up by creating some chains in an attempt to restrain the girl before she could make any more moves. Matching his speed, Star simply dodged them before firing another blast of sticky hearts as Marco returned to the ground. Thinking fast, Marco immediately ducked. However, some of the substance managed to hit the visor on his helmet, causing him to be blinded. Marco immediately removed the helmet to try and get a clearer vision. Wait, why didn't I just use my powers to remove it! Before he could scold himself over this mistake, he saw Star fly towards him. Without thinking, Marco threw his helmet at Star, sending her off course crashing into a nearby pole. Marco felt a pang of guilt at this. Sorry, Star. When Star floated up, she seemed to be temporarily dazed. Wait, why did I do that? The Pheromones could still be active! Again, Marco wanted to scold himself over another dumb mistake mentally, but he knew he might not get another chance. Without the helmet, he had to end the fight quickly or risk losing himself to the pheromones. Seeing his chance Marco decided to use one of the Moves he practiced last week.

"Crimson Bindings!" Marco yelled before his fingers started changing crimson in color and turning metallic. He then extended them towards Star. While she was able to dodge them, she failed to notice that they haven't retracted themselves, Marco then brought his fingers together, causing the bindings to wrap themselves around Star.

Star tried to break free, but this time she couldn't break the bindings that were wrapped tightly. "Don't worry Star. It will all be over soon," Marco reassured her while looking at his watch, which reads 3:45.

Whenever Star tried to break free, Marco would tighten the bindings a little preventing her from escaping. Marco hated doing this to her best friend, and he hated himself for getting rid of his helmet, which was the only thing hiding his identity. If Star remembered anything about this afterward, then he expected to have a lot of explaining to do.

"Star, I don't know if you can hear me in there, but if you can, then I know you must have a lot of questions. I just want to let you know that you don't need to worry. I'll explain everything to you when this is all over, and I hope that you'll still want to be my friend," Marco said as sincerely as he possibly could.

Suddenly, Star let out a whimper of pain, and then uttered a single word: "Marco?" When Marco heard her say his name, his eyes widened in shock, causing him to loosen his grip. Star's pained expression then turned into a wicked grin, before suddenly breaking free of the binding. Marco had no choice but to retract his attack, causing his fingers to return to normal. Star immediately tackled Marco to the ground, and before the boy could do anything, Star shot at Marco's arms and legs binding them together.

"Star, stop this!" Marco pleaded in a panicked tone expecting Star to go back to Oskar now that she had him restrained. Instead, Star started looking at Oskar and then back at him as if choosing between the two. Marco couldn't help but notice this. Wait, is- is she trying to choose between Oskar and me? But why would she want me, she doesn't like me like- oh no. Marco suddenly remembered everything Glossaryck had said about who Star was looking for: someone she had a strong emotional connection to, someone who could take care of her, and someone with the genes to create powerful children. Marco already had the first two checked off, but with his heritage, that gave him all three!

HOW THE HELL COULD I FORGOT ABOUT THAT I'M HALF CELESTIAL? NOW SHE'S GONNA COME AFTER ME FOR SURE!!! For the third time in the last few minutes, Marco wished he could mentally slap himself for his stupidity. When he saw a dark shadow above him, he snapped out of his mental scolding and got a very nervous look on his face. Star was hovering right above him, focusing on him and him alone and grinning widely, like he was something good to eat. Oh no, I've seen enough harem anime to know where this leads! Marco thought. He tried to create another knife or anything to get him out of this mess. Before he could, though, Star suddenly blasted him point-blank with some sort of purple mist. It took a few seconds for him to realize that his mist was, in fact, the same pheromones Star was exuding. Only this time, he was getting a far more concentrated dose.

"Star, what *cough* are you doing!?" Marco managed to get out as she continued to blast him with more of the pheromones. When Marco tried to materialize anything, he suddenly felt his head hurt. As a result, any attempt to use his powers ended with any objects made to fall apart.

Why does my head feel so weird? I can barely focus, bare-bar-ba, Marco thought as he felt himself falling into a daze.

The creature smiled. What parts of her brain that still operated couldn't help but feel satisfied. While part of its brain still wanted her to return for the other male with the keytar, every fiber of it knew that the male below her was the one. The creature had been surprised that any of the males in this area could shake off her pheromones, let alone be able to subdue her. While it took more effort than she expected, the male was now hers, and she could hardly believe how powerful he was! Whatever dim parts of her mind that recognized her from the before time knew that he was strong, but not to this extent. The children they could have would be unstoppable. But first, the creature decided that she must relish in her victory.

Seeing that he had finally started to succumb to the pheromones, Star wrapped Marco in even more threads before carrying him bridal style to the rooftop. She then paused, looking up at the sky and basking in her victory and what was to come with her chosen mate.

"Star." The creature looked down at the boy. Despite everything, part of him still had the power to resist as he weakly squirmed in Star's hold. "Star, please stop this. This isn't you," he begged. Paying his words no mind, Star then started to remove the armor Marco made. He could only squirm in a useless attempt to break free. Every time he would try to call forth his power, his head would ache, preventing him from escaping. When the last of Marco's armor was removed, he felt helpless against Star, who was now looking at him like a predator who has captured its prey.

With what little willpower he had left, Marco was able to get a look at his watch and saw that it was now 3:52. Five...five more minutes. I have to get her back...to normal in the next five minutes or lose her forever. The thought of losing the friend that had brought so much fun and purpose into his life seemed to ignite a fire inside of him.

Deep within Marco's mind, in a familiar setting that he couldn't recall in his current state, a sphere of light began to hum and vibrate before glowing even brighter. As if it was acting in response to Marco's thoughts.

I can't give up now! I just have to hold her off for five minutes! With all his willpower, instead of trying to create an object, the young half-Celestial focused it on his shapeshifting. Think of what you need to stop Star!!

After a few seconds, Marco started screaming, causing Star to back off in shock. "Aaaarrrggghhhh," Marco rolled off his back to reveal a pair of massive, metallic wings protruding out of his back, with feathers that seemed to double as blades. Before Star could restrain him again, Marco used his powers to strengthen his muscles temporarily to break free of his bindings, before flying up into the sky with Star following him.

Marco was now flying into the sky above Echo Creek Academy, with Star on his trail, never losing her predatory grin. It's like she's enjoying the hunt, Marco thought as he looks at his watch- 3:54 just three more minutes.

Star shot more of her thread at Marco again. Seeing this, he covered his body with his wings and began to spin around like a top, deflecting the blast.

Marco could feel the effect of the pheromones wearing off now that the mist no longer surrounded him. 3:55 just a little more. Wait where did Star go? Marco had taken his eyes off his watch for a second, but now Star was nowhere to be seen. Using his enhanced senses, Marco tried to search the sky, seeing where his friend had gone.

He then felt something tackle him from behind. When he turned his head, he saw that it was Star who now had a crazed look in her eyes before wrapping her arms around Marco's body with the top pair grabbing onto his wings, causing them to fall from the sky.

"Let go, Star!" Marco yells as they start falling, thinking quick Marco transformed one of his arms into a gorilla arm before grabbing Star from behind him and throwing her in front of him. When Star managed to correct herself and flew towards Marco, he decided to end the fight. Despite not wanting to hurt Star, he knew that he needed to do this for her own good.

Marco then created a giant rocky first, and combined with his Gorilla arm, began to punch Star like there was no tomorrow.

Marco unleashed a flurry of punches on Star, holding back just enough to keep from seriously injuring her. After a few seconds, Star finally lost consciousness and began falling to the ground. Thinking fast, Marco immediately flew down to catch Star before she fell to her possible death.

(End Music)

Marco transformed one of his arms into a tentacle arm before extending it forward and wrapping itself around Star as he brings her to him closer, carrying her bridal style as descends to the ground.

When Marco landed on the ground, he heard a beeping noise from his watch. He saw that it was now 3:57. Before he knew it, Star's body started glowing in a flash of light, causing Marco to close his eyes when he opens it, he saw that Star was turning back to normal, with her insectoid features falling off of her as purple hearts onto the ground.

"Star, you're back!" Marco says happily as he laid Star down on a pile of purple hearts.

"Star?" Marco said worriedly when he saw Star wasn't waking up.

"She'll be out for a while," a familiar voice spoke from behind Marco, startling him in the process.

When he turned around, he saw that it was Glossaryck who had the same smug smile he had from before "G-glossaryck!?" Marco said in an alarmed tone, especially since he hasn't retracted his wings yet.

"That's right kid, it's me, Glossaryck! And before you ask yes, I saw the whole thing," Glossaryk said smugly.

Marco remains quiet while sweating nervously while thinking whether or not someone else witnessed the event. "All right, I can explain."

"I don't think you can. But as much as I'd love to hear you try, don't worry, kid. No one else saw what happened. And don't worry about Star, she'll only remember bits and pieces of what transpired. However, it seems that my suspicions were correct". Glossaryck said, making Marco even more nervous.

"R-really? What exactly is that suspicion Glossaryck," Marco said nervously as he retracts his wings.

"Do I have to spell it out? Of course, it's whether or not you're a Celestial, my boy".

As soon as he said, "Celestial," Marco felt like his heart could jump out of his chest in shock.

"I have to say; it's been a long time since I've met one, you know. Though what puzzles me more is to find one living on the same planet where we sent my student to. And for you to not only befriend said student but be living with her under the same roof." Glossaryk said as he gestured to Star before speaking up again.

"I knew those stories about you guys dying weren't true. I'm also surprised to meet one as young as you," Glossaryk said.

Knowing Marco couldn't possibly lie his way out of this one, he decided to speak up. "It's because I'm only half-Celestial. My mother was human, Glossaryck."

Hearing this, Glossaryck eyes widened briefly before speaking up, "A hybrid you say, I can't believe they actually did it. I thought they would never trust a non-Celestial again especially after the whole 'incident' "

"Incident?" Marco questioned

"Oh, that's not for me to say, kid. Now, does Star know about you?" Glossaryck questioned, now with a very serious look on his face.

Marco shook his head at this.

"I see. Well, then, that may partially explain why she didn't go after you from the start. It took her some time, but eventually, part of her brain realized that you had immense power within you. Be grateful you fended her off when you did. As fascinating as it would be, I don't think the universe is ready for Butterfly-Celestial hybrid kids running around."

Hearing this made Marco's face turn as red as his hoodie. "Do you have to phrase it like that?"

"Relax, I'm just messing with you." The blue man said chuckling. However, then the look on his face became very serious. "You're putting yourself in a potentially dangerous situation, you know. The Celestials were long sought after for their power, with many foolhardy groups trying to gain control of it. Now that you're friends with the Princess of Mewni, you'll become as big a target as her. If the wrong people were to find out what you are, they would seek to use you for their own purpose," Glossaryck said in a serious tone.

"I won't let that happen, and I'll make sure no one finds out," Marco said with a determined look.

"Does that include Star?" Glossaryk asked, catching Marco off-guard with the question.

For the past few days, Marco had wondered if he should finally tell Star what he was, but he always pushed the thought aside.

"I--" Before Marco could answer Glossaryck cut him off, "Well looks like Star is waking up," Glossaryck said while pointing to Star, who was now coming to.

"Star!" Marco runs to Star immediately, leaving Glossaryck with his thoughts. The universe really works in mysterious ways, he thought before disappearing in a puff of smoke.

"You're awake," Marco cried out in relief as he hugged Star, who happily returned it. This hug was interrupted by a buzzing noise.

The two pulled away as Star moved her hair to the side to reveal two small insect wings causing Star to squeal happily.

"*Gasp* I got my Mewberty wings!" Star said happily before putting her hair in a ponytail.

"*Gasp* does that mean you can fly?" Marco asks excitedly remembering his experience flying from earlier

"Let's test it out!" Star exclaimed excitedly, grabbing Marco's hand with no adverse consequences. She then jumped, flying through the air with Marco for about 3 seconds before falling to the ground "Nope," Star said deadpan.


Later, everyone's brushed off what had happened, with the Principal deciding to let everyone head home early. When Marco asked whether Star remembered what happened during Mewberty, she said she didn't remember. All she could recall were bits and pieces of fighting someone. Good, then my secret's still safe, Marco thought, relieved since he wouldn't have to explain to Star that he was the one who fought her.

"By the way, Marco, where were you during the whole Mewberty thing?" Star questioned.

This caused Marco to jump in place before answering, "Uh, I actually don't remember since I was also affected by your pheromones Star," Marco responded nervously.

"Hmm, that makes sense. People involved in Mewberty usually don't remember anything," Star said until, suddenly, an image appeared in her head. It was of a boy who was also wearing a red hoodie, restraining her. He could hear echoes of his voice, but when she tried to remember his face, he couldn't recall it. Who was that? Star thought as she looked at Marco Was that-no, it couldn't be. Marco is only a human, Star thought as she pushed the image in her head aside as she and Marco made their way home.

Unknown to Marco, there was a now a small crack growing on his arm.


CELESTIAL JOURNAL

Limb Generation- using their ability to shapeshift, Celestials are able to grow additional body parts like extra arms or legs. This also allows them to grow parts that are not natural to their current form like wings or even a tail.


AUTHOR'S NOTE: Hello my dear readers Rothem here back with a new chapter again. I have to admit seeing how other writers can get a bit 'raunchy' when they are also writing mewberty, I was a bit uncomfortable with making this chapter thankfully I had my beta reader to help me who by the way has a message as well like usual.

Hey, everybody, it's your beta editor Jay here! Of all the chapters that ROTHEM had planned, this was one of two that I looked forward to doing the most. Why? Well, three reasons:

First, ROTHEM agreed that the Mewberty story would be the first real opportunity for Marco to cut loose with his powers. We added in the pheromones thing so that there wouldn't be anyone able to witness Marco using his powers.

Second: It gives us the opportunity to write some cool action scenes and load them with references.

And three, and I need you to pay attention to this one: the shipping fuel. A lot of fanfic for the show that deals with Mewberty go one of two ways with it. They either have her go after Oskar like in the show or make Marco her target because of StarCo. So, why not?

See you guys next chapter, becasue this is going to be the one where things really hit the fan! Now, if you'll excuse me, I have to go buy a new suit for a dance.

Rothem: Yeah anyway feel free to leave a review as they are always appreciated. Also feel free to favorite or follow the Story for those of you who haven't yet. By the way here are the responses for my two reviews from the previous chapter.

Starco4everr-thank you very much, glad to see your continued support for this story.

Gobert600-while I don't want to spoil any of my plans for the story, the scissors will be owned by Marco at least since he's the one who worked to win them.

Anyway see you guys next chapter!
