Drama and Danger Grow in Sly Moon Prime

Previous ChapterNext Chapter

In our last chapter, Shaggy, Scooby, Misty and Sunny saw the true nature of Aruna, the beloved Sun Jaguar on Earth-- she was actually nasty, vindictive and abusive toward her own twin sister, Umbra, who was a Moon Jaguar who had been banished to the dark side of the moon for the past 10 years, never getting to be in the daylight or see the sunrise.

Misty knew how it felt to be locked away somewhere, lost and alone, so she and the others instantly offered their friendship to her and offered to protect her from Aruna, and Umbra gladly accepted their friendship before they all went off to find something for Umbra, Shaggy and Scooby to eat.

But there was still a big problem on the moon that night-- the Sly Star One still needed to be repaired before the crew could leave for Earth again, and the alien was still out there somewhere, waiting to strike, while Aruna knew her sister was around and she needed to get her revenge on Umbra while trying to complete the tasks that Alterro has given her.

It makes all of us wonder... what is going to happen next?

Well, you better fasten your seatbelts, cause we're about to find out in just a couple of minutes.

Back in the work area Hudson had set up, Steelcase and Elvin, along with Starshine Tide, Hitch, Izzy, Sparky, Pipp, Cassiopeia and Tidal Wave, were working on the Sly Star One to get it ready to go back to Earth.

Fred and Daphne were there too, and needless to say, Fred was rather excited to get to be working alongside his heroes. “Wow, look at all this cool stuff,” he said, holding a hammer. “I don't even know what half of it does!”

Izzy let out a yelp and immediately grabbed the hammer from mid-air as Fred tossed it aside, panting slightly. “Phew… is it me or is it kinda tough to keep up with Freddy when he’s so… all over the place?”

“You’re not wrong, Izzy,” Hitch responded back, wiping his face before feeding Sparky a cookie. “I think meeting Steelcase and Elvin is kinda getting to his head.”

“Hey, Hitch! Toss me one of those cookies, would ya?!” Starshine called out from where she was reattaching a loose piece of metal. “It’s hungry work trying to fix this thing!”

“Sure thing! Coming at ya!” Hitch said before tossing the cookie up, which Starshine immediately caught in mid-air. “Phew… thanks, Hitchster!”

That was when Fred spotted a fire hydrant-like device not too far away from the rest of the tools. “Check this out!”

Elvin looked at him a little worried as Fred tried to figure out what the device did. “Maybe you shouldn't touch that.”

“It's a coolant gel,” Steelcase explained. “Used to extinguish fires by…”

But when Fred hit the trigger, it sent a blast of gel toward Cassiopeia, Daphne and Pipp, but while Cassie was able to get out of the way, Daphne and Pipp got hit, causing them to scream and causing Steelcase to sigh to himself. “...totally emersing it in gel.”

“Fred!” Daphne cried out. “Seriously?! Come on!” Pipp groaned. “Do you know how hard this is gonna be getting it out of my mane?!”

“Sorry, girls! Let me... wow, look at this thing,” Fred picked up another canister with interest, completely forgetting about Daphne and Pipp. “I wouldn’t touch that, Fred,” Tidal warned. “It's oxygen imbued liquid nitrogen. If that goes off…”

But completely ignoring him, Fred pressed the tap and the nitrogen sprayed him, freezing him in a instant and causing Tidal to sigh irritably. “...you’ll get frozen in a block of ice.”

“Oh, wow,” Cassiopeia blinked in surprise. “That’s, uh… that’s quite a powerhouse of chemicals.”

“And this ice is thick,” Starshine said, tapping the ice with her claw. “Yikes!! And cold!”

However, as the young creatures were trying to figure out how to get Fred out of the ice, Elvin picked up a hammer and prepared to bust the ice himself… that is, until Steelcase stopped him. “Zip, what are you doing?”

Elvin looked at him as if he were crazy. “I'm gonna get him out of there.”

Steelcase approached him with a slight smirk. “Really? You think that's a good idea? You hear that?”

But, when the others lifted their ears to listen, they didn't hear a single sound... exactly what Steelcase was referring to at the time. “It’s all quiet... peaceful... no Fred talking our ears off...”

“Oh, right,” Elvin chuckled before he walked over to Fred and waved his hand at him before he tapped the ice around Fred's helmet. “How long can someone survive in that?”

“Depends,” Steelcase shrugged. “How long do you want to enjoy the blissful sound of not hearing his voice?”

“Uh... half hour?”

“Yep. Sounds about right.”

“What, what?!” Cassiopeia was immediately against the idea. “But you can't just leave him stuck in one place!”

“Cassie has a point,” Starshine agreed as Izzy and Tidal tried to pull Daphne and Pipp out of the gel. “He'II die if he stays stuck in that icy prison for a long time.”

However, Steelcase didn't seem all that worried. “Don't worry. We'II get him out after a half hour of not listening to his annoying voice. Now, hand me those calipers.”

Starshine let out a sigh before doing as she was told while the rest of the group tried to get Daphne and Pipp out of the slime.

But needless to say... this was going to take quite a long while.

In the kitchen, U-Boat was using the microwave to heat him up some food, but as he took it out of the microwave, he heard H.A.M's voice off to the side. “Interesting.”

That was when U-Boat turned to face the somewhat human-looking robot, who was smirking to himself before he spoke again. “I thought you didn't trust anything that's not human. A microwave isn't human. Yet you let it make your food.”

U-Boat seemed to glare over at him before he went over to the cabinet and pulled out a can of tomatoes, but as he turned around, he saw H.A.M holding up an electric can opener, with the same smirk on his face. “You'll be needing this, I suppose. Another machine. See? Machines are useful. Machines are...”

However, H.A.M was cut off when U-Boat quickly crushed the can opener with one squeeze of his hand, squishing the tomato can with his other hand before walking off, leaving a nervous H.A.M to try and realize what just happened before running out of the kitchen.

U-Boat walked over to the table and emptied the tomato cans over his burritos, and Velma, who had witnessed the entire thing with Zipp, Clark, Cloudy and Shutter Snap, finally decided to speak up. “Jinkies. You really don't like robots, do you?”

Cloudy let out a slight scoff to this. “That’s the understatement of the year. As long as I've known him, machines and robots have sort of been his mortal enemy.”

That was when Clark, who had been admiring his reflection in a spoon, finally turned to look over at U-Boat. “I guess you don't take to progress very well.”

U-Boat's eyes narrowed at this. “Progress?”

“Oh, brother...” Shutter Snap immediately shuddered when she heard this. “Here we go...”

“You mean the sort of progress that put automated machines in the car factories?” U-Boat continued to question Clark, clearly not pleased. “The sort of progress that put my father and hundreds of others like him out of work when I was a kid? That sort of progress?”

And with that, U-Boat crushed the spoon that Clark was holding before grabbing his plate and walking out of the kitchen. “Geez...” Zipp muttered with a bit of fear and suspicion in her tone. “If he had his way, we wouldn't have planes let alone the technology to fly to the moon.”

Velma hummed in thought at this, and Cloudy spared her a slight glance. “I know that look by now, Velma. You can't honestly think that U-Boat is responsible for that alien thing. He's been with me through 98% of the whole trip.”

“I don’t think he's responsible yet, Cloudy,” Velma responded, looking at the doors that U-Boat left through. “I just need the evidence to prove that someone is responsible for the alien... but I'm just not sure where to look for it.”

“So you see, Opaline was trapped in the Together Trees forever,” Sunny started to conclude the story of Opaline's final defeat to Umbra as she, Umbra, Misty, Shaggy and Scooby all walked together, “and we don’t think that she’s ever gonna come back. But if she does… we’ll be ready for her, especially since we have dragons on our side.”

“Wow... she really was a monster, just like Misty said,” Umbra muttered softly, eyes trailing to the floor. “It makes Aruna look like a saint... well, sort of.”

“Everyone, no matter who they grow up to be or what species they are, has the ability to make choices good and bad,” Misty said, her eyes filled with a gentle warmth. “And sometimes, ponies make mistakes. But it's what we do in the end that counts.”

Umbra nodded in agreement to this. “...I know that. I just hope my sister can realize it before long.”

That was when Misty noticed that Shaggy and Scooby had been pretty silent while they were talking to Umbra, getting her curious almost immediately. “Hey... is something okay, guys? I don't think I've ever heard you be this silent before.”

“We were just thinking, and… maybe U-Boat and Cloudy were right before,” Shaggy told the others with a shrug. “Maybe that alien was only in our heads.”

That was when Scooby looked outside the window and saw the alien crawling along one of the buildings, causing him to run back to the others. “Yeah, just like that alien.”

“Huh?!” the girls cried out and turned to see the alien’s tail disappearing from sight. “Uh… yep,” Misty chuckled nervously. “That alien's not really there.”

But as they walked on, the alien appeared outside of another window, causing Umbra to gulp nervously. “Neither is that one!”

And then, as their walk began to turn into a run, the alien appeared on another window, causing them to screech to a halt. “Or that one!” Shaggy cried out. “Come on, guys! This way!” Sunny exclaimed as she tried to urge her friends in another direction. “RUN!!”

“YIKES!!!” everyone shrieked and broke into a very fast run down the hallway before screeching around a corner, where Umbra saw some double doors ahead of them. “Quick! Run in there!”

“Good thinking!” Misty cried out, slightly panting as the door automatically opened for them before they ran inside, causing the door to slam shut.

This allowed the group to get their bearings, not used to being chased by something from the outside. “Like, we lost him,” Shaggy said in relief as Scooby turned around. “I think we’re okay, Scoob!”

“Yeah,” Scooby nodded to Shaggy's claim, smiling upon seeing an amazing sight in front of him. “More than okay.”

Umbra gasped as soon as she saw what Scooby was seeing. “Girls… you have to see this!”

Sunny, Misty and Shaggy slowly turned around to see what Scooby and Umbra were staring at, and they found that they were actually in a very large dining room, with different kinds of food are piled up neatly all around the room.

And seeing all this food caused Shaggy to gasp, not seeing the alien anywhere around. “There's no alien. Yup, no alien at all. We're just hungry. That's all!”

“Yeah!” Scooby nodded as he quickly ran after Shaggy. “We need to eat that alien away!”

“I don’t really know how you EAT an alien away, but… I am feeling kinda hungry myself,” Sunny shrugged before turning to Misty and Umbra. “You girls feel like joining in?”

“I thought you would never ask, Sunny-- come on!” Umbra cried before running forward, causing Sunny and Misty to laugh before they followed their friends into the dining room to eat their hearts out.

XXXXXXXX

Needless to say, Sunny, Misty and Umbra got full of their makeshift meal rather quickly, but as for Shaggy and Scooby, they continued to eat for what felt like ages before they decided to take some food to their friends working on the Sly Star One, in case they were getting hungry.

Scooby sighed rather contently as he and Shaggy carried giant stacks of food toward the doors. “Ah… I feel better already.”

“Me too, Scoob,” Shaggy nodded. “This spread is a…”

“Uh… everyone? I don’t wanna be the bearer of bad news or anything,” Umbra said, gulping nervously at something ahead of them, “but… I think we have a bit of… unwanted company.”

“Oh, no,” Misty looked worried. “Don’t tell us it’s Aruna!”

“No… it’s not her,” Umbra squeaked, her eyes wide in terror. “It’s someone much… much worse…”

That was when the two ponies, Shaggy and Scooby finally looked up and trembled upon seeing the alien towering in front of them, causing Misty to quickly fire up her horn and create a distraction. “GET DOWN!!!”

As Misty shot a beam of magic at the alien, the alien sliced through the piles of food, causing Shaggy and Scooby to run while Umbra, Sunny and Misty tried to get rid of the alien by fighting it using magic and physical combat. The alien even tried to throw a table at Shaggy and Scooby, but Sunny was able to grab it with her alicorn magic aura and threw it back at the alien, who narrowly dodged it.

Umbra was able to get Shaggy and Scooby to hide behind the dessert table, and while Umbra tried to think of a plan to get her friends out safely, Shaggy and Scooby were visibly shaking and eating from their stacks of food in order to calm their nerves. “I am so scared!” Shaggy wailed, causing Scooby to nod quickly in agreement. “Me too!”

“AGH!!!” Sunny screamed as she was suddenly tossed over the dessert table, with Misty following right after. “Girls!” Umbra cried. “Are you all right?”

“Ugh… we’re fine, thankfully,” Sunny groaned, “but that alien is a lot stronger than I thought he would be!”

Suddenly, the alien appeared behind them and smashed right through the table, revealing their hiding place and causing them to run and try and find another place to hide.

After shaking off the ice cream it had splattered on its face, the alien went toward a glass statue of Sly and sliced it with its massive claws, causing it to shatter upon hitting the floor. Then, after looking around, the alien spotted Sunny levitating Umbra onto the chandelier with Shaggy, Scooby and Misty… a chandelier much too high for any human being to jump to.

Shaggy smirked down at the alien, holding a small plate of food in his hands. “Sorry, Mr. Alien, like, this table is for the five of us.”

“Plus, you can't reach it. Unless aliens can jump really high,” Scooby added before turning to the others. “Can aliens jump really high?”

“I don’t know,” Misty shuddered, “and honestly? I really don’t wanna find out.”

Suddenly, the alien opened its mouth and emitted a high-pitched scream that broke plates, glasses and flowerpots all around the room, as well as deafening our heroes. And to make matters worse, the chandelier began to shake, causing the ponies, Umbra, Shaggy and Scooby to scream and fall to the floor, just before the chandelier came loose and fell right down on top of them. “Oh, no!” Misty strained as she tried to lift the chandelier, but to no avail. “We’re trapped!”

Upon seeing her friends so terrified for their lives, Umbra knew that she couldn’t stand by and do nothing any longer. So, she leapt out of the chandelier and onto the ground in front of the alien before roaring at the top of her lungs, startling the others and even scaring the alien.

And after her roar, Umbra took on a fighting stance as wings of shadow began to appear on her back. “If you want to hurt my friends, you’re going to have to go through me first!”

The alien let out a growl of its own, but Umbra wasn’t fazed. In fact, she turned to her friends with a stern look. “Sunny! You and Misty get your friends out of here! I’ll take care of the beast!”

“Umbra, no!” Sunny tried to plead. “That thing is way too dangerous!”

“It’s a chance I have to take,” Umbra said seriously. “Just go… GO!”

And upon realizing that Umbra wasn't going to change her mind, no matter what they said, Misty and Sunny nodded as Umbra and the alien tackled one another with roars and snarls filling their throats. And while Umbra was busy battling the beast, the two ponies used the invisibility spell to sneak Shaggy and Scooby out of the room and through the double doors, hoping to find their friends before it was too late.

It was around that time that Fred had finally been released from the hydrogen ice, and as the group took a break from working on the Sly Star One, Fred took the opportunity to talk to his heroes again… much to the others’ slight annoyance. “So you guys were on the very first mission, right? That's so cool,” Fred kept saying. “You probably have a huge following on the Internet and have your own blog, but it wasn't around then. Heck, I don't think there were even computers back then. Ha, ha.”

“Fred… I mean this in the NICEST way possible,” Pipp said gently, putting a hoof on his hand, “but… I really need you to shut up. Like, right now. Please?”

Fred smiled sheepishly at this, causing Steelcase to sigh in annoyance. “Ah, we should've left him in the ice.”

“I still can't feel my fingers,” Fred spoke up after a moment. “Would you like me to freeze him again for you?” Cassiopeia asked. “My mom taught me a freezing spell a while back that I think could…”

“No, that’s okay, Cassie. I’m sure Steelcase was just… kidding,” Tidal said with a somewhat nervous smile. “Or at least… I hope he was kidding…”

That was when Daphne spotted some blue looking liquid on the floor next to her, immediately stepping back with disgust. “Eww… what’s that?”

Steelcase looked at the puddle of liquid and then at the vents above them, automatically assuming what it was. “Condensation. Probably from the air vents.”

“Looks like alien juice to me,” Daphne said with a slightly disgusted frown. “And you’ve seen alien juice before?” Hitch raised an eyebrow, as did Sparky. “No, not exactly,” said Daphne. “But if I were to take a guess at what it looked like, I would say it would look a lot like that.”

Steelcase let out an irritated sigh at this. “Could this day get any worse?”

That was when Shaggy, Scooby, Misty and Sunny were heard screaming before they ran right into the others, causing them to collapse into a huge pile on the floor. “Sunny, guys!” Izzy panted, trying to get out from under the huge pile of people. “What’s going on? Why were you running so fast?”

“Alien! Big!” Shaggy panted as he and Scooby got up. “Attacking Umbra!”

“It hates food!” Scooby immediately blurt out, looking just as panicked as the others did. “And likes melting brains!”

“Wait, hold on a second,” Starshine raised an eyebrow. “Who’s Umbra?”

“Believe it or not,” said Sunny, “she’s Aruna’s twin sister-- a Moon Jaguar!”

“A Moon Jaguar? Seriously?” Pipp’s eyes widened in surprise. “And she’s fighting off that alien we saw on the monitors?”

“She was willing to fight it off to save us!” Misty added, her eyes wide with worry. “There’s a whole story behind Umbra later, but we can’t tell it to you right now-- we have to get back there and save her before it’s too late!”

“Wait,” Daphne immediately stopped the conversation. “Where did you leave Umbra and the alien last?”

“Dude!” Shaggy panted. “In the restaurant!”

“And you left before you were done eating?” Fred asked in surprise, causing Shaggy and Scooby to nod. “Uh-huh.”

“Okay… that definitely proves that something was in that restaurant,” Hitch said. “Shaggy and Scooby would NEVER leave any kind of food behind, and if Sunny and Misty say there’s a Moon Jaguar fighting the alien in there, I say there is!”

“And that’s the total, absolute truth!” Misty said fiercely, just before Scooby lifted a paw. “So help me, hot dogs.”

“Okay,” Elvin sighed and rolled his eyes. “Let’s go take a look.”

“Sure, why not?” Steelcase smirked slightly. “I could use a good laugh.”

“Pipp, call the others and tell them to meet us at the restaurant as fast as they can,” Sunny told the pegasus mare as they began to head toward the restaurant. “But make sure Aruna doesn’t hear about Umbra!”

Pipp seemed pretty confused at this sort of request but reluctantly did as she was told as she and her friends, both new and old, headed toward the restaurant to see what was going on with the alien and Umbra situation.

But little did they realize that Aruna did hear about this situation and was now growling with fury, her eyes glowing a sadistic orange. “They’ve joined forces with my sister?! That does it… I need to call Alterro and tell him there’s been a change in plans. If we BOTH want to get the revenge we deserve, we need to figure out this alien’s next movements and THEN strike.”

And so, making her wings appear, Aruna flew off further into the base, sort of dreading telling her ultra-powerful master that there was a change in plans, but then again, if it got her sister off of her back and those ponies off of Alterro's back for good... there didn't seem to be any use in complaining.
