Alright, readers, this is the story that I came up with for this series as I have mentioned in my profile!

Now first off, this is the first story that I'm doing for this series, and it's my very first time, so don't be surprised.

Secondly, as I stated in my profile, this story will be based on and inspired heavily by Sonic Adventure 2; something that I don't think any writer for this series has done before. So if you're not familiar with the game, don't be surprised by how this story is set up.

Also, for this story, the seven Miracle Gemstones will be introduced and the characters from the show as well as the OC characters will act like they've known of the gemstones all this time. The gemstones are made to work similarly to the Chaos Emeralds, and to balance out the gemstones will be the Ruler Gemstone, a big gemstone relic that works like the relic Master Emerald. This is just a heads up for you all.

Another thing, as I said on my profile, most of the setup of this story for the series will be given some altercations to make it flow like the game it's based on, while at the same time, many of the references and pinpoints from the show itself will be included as well. Also, a little notice that this story will take place two years in-universe after the show started and Star moved to Earth.

And that brings me to the next thing, regarding traveling through dimensions like the show utilized. As mentioned on my profile, I'll be putting that to full use and having the characters travel through dimensions to places that would be similar to the action stages that said places are based on. I just want to throw this out to you guys so there's no confusion.

Lastly, in addition to 5 actual characters from the show playing a big role, 2 other OCs will be given a role in this story. One of them is going to be an expert treasure hunter and the guardian of the aforementioned Ruler Gemstone, and the other one will be the main enemy rival who was made to rival against Star and be put at odds against the princess of Mewni. Just letting you guys know now.

Well with this explained, I hope you looked at everything else on my profile page to see what this story will be about, and on that note, I hope you do enjoy this story!

21:02 - INSIDE A MILITARY BASE ON JAIL ISLAND LOCATED ON EARTH:

"Intruder alert! Intruder alert! Security breach at gate 3! The intruder has been located in the North Quadrants, and is moving in the direction of the underground base! All units prepare to engage! Emergency battle formations! Standard Battle Procedures initiated! Locate and stop the intruder from entering the security area! This is not a drill! Repeat: This is not a drill!"

As the computerized voice had made that announcement, initiating a lockdown of the base, as a result, the intruder was blasting his way through the guard robots that stood in his path, using what appeared to be a creepy looking staff that shot green lasers, which successfully turned the robots into scrap. The intruder was identified as none other than Ludo Avarius. Ludo was shown to be a tiny 2 ft Avarian; a bird-like monster of some sort. He was shown wearing a brand new bull skull cap that he had gotten, as well as a new robe while keeping the beard he had gotten since his previous castle got blown up and when he got thrown into that portal. Accompanying Ludo was a giant spider that he was riding atop of, and an eagle that was perking on the back of the spider. As soon as Ludo used his staff to blast the robots to bits, he then held it down sideways as the spider walked over to a ledge.

"Ha ha ha ha ha, that was all too easy," Ludo chortled as he peaked over the ledge. "Now then, let's take a look at what my grandfather was working on; a top-secret military weapon. The military shut down this research because they feared it."

The spider with Ludo and the eagle in tow then jumped down, preparing the intrusion to the center of the base.

Intruder alert, assume level 1 defense formation!

Ludo paid no attention to that as he focused on getting to the location.

Believe it or not, the source of motivation for Ludo's intrusion in this military base occurred when Ludo was at his new castle that was made with a new army accompanying it, which was possible thanks to Dennis, he stumbled upon what was his grandfathers' diary. The diary revealed that there was a top-secret military weapon in this very base that was shut down due to fear that the military of the US had felt.

As a young Avarian, Ludo had seen his grandfather Professor Gudo Avarius as his idol and someone he admired. Unfortunately, his parents did not approve of Gudo's achievements and did not see eye to eye with the professor, so they cut all their connections with him, and they forced Ludo into repressing all his memories about his grandfather by abusing him into forgetting, which worked for a long time, but the abuse didn't stop there. All of his brothers (sans Dennis) were encouraged by his father into bullying him mercilessly and it was not just because of his inability to grow in size and fly either. There was also the possibility of the repressed memories of his grandfather could surface right back if an action wasn't taken, and it seemed that the memories did resurface thanks to the discovery of his grandfather's diary.

I really do feel regret and shame for repressing my memories of my grandfather after all these years. Ludo thought to himself as he blasted more guard robots. To make up for that, I'm gonna find out what this top secret research project he worked on is.

With that said, he blasted the first security door with his staff.

Level 1 security door breached; emergency formation, intercept intruder!

"Bah, what a bunch of incompetent fools," Ludo huffed. "Spider and Eagle, let's take care of these pests!"

They both obliged as they took out the guard robots easily with three different methods; the spider webs that rendered them unable to move, being snapped into half by the massive beak of the eagle and blasted to smithereens by Ludo's staff that shot green lasers.

Soon enough, they made it to the second security door that was also taken down.

LEVEL 2 Security Door Breached! LEVEL 2 Security Door Breached!

As the red sirens started going off, Ludo and his companions went onto an elevator of some sort that descended downward. While waiting, flying robots tried to ambush and get them to let down their guard, but they weren't any match for Ludo and his determination. As soon as they got off the elevator, they continued onward. Just the sight of having defeated those robots caused Ludo to smirk since these guards were pushovers.

"Ha, so much for having one of the most heavily guarded military bases around on Earth."

Ludo then shot down a security camera with his staff before busting down the third security door.

LEVEL 3 Security Door Breached! The intruder has breached Sections 3 through 8! Get him!

Obviously, nothing could stand in his way as the robots were taken down and turned to scrap in a matter of seconds. He followed the red arrows which led to the heart of the base and before he knew it, the fourth security door was in sight. Wasting no time, the door was taken down as well.

LEVEL 4 SECURITY DOOR BREACHED!

Another elevator-like platform was waiting beyond the door as they got onto it yet again, following the same procedure. All the robots that planned on ambushing him were taken out without breaking a sweat and they got to the bottom. By this point, the base was flashing red in all areas and the sirens were blaring loudly, but Ludo didn't care. The secret weapon of his grandfathers was within reach, and nobody was getting in his way.

"Away with you pests," he barked before blasting more guards and then breaking down the fifth security door.

LEVEL 5 SECURITY DOOR BREACHED! SWITCH TO EMERGENCY DEFENSE MODE! LOCKDOWN FINAL SECURITY DOORS!

Ludo shrugged that off as he and his companions then burst through the sixth security door, getting closer to the center of the base.

By this point, the base had issued a fleet of robots to stop Ludo in his tracks, but he and his girls unleashed everything they had on them and broke right through them.

"Is that the best they can do," he asked rhetorically.

He was then met with a hallway that got closed up by security doors that couldn't be blasted down by all means.

"Well, at least they stepped it up a little this time."

The eagle then screeched and directed his attention to a nearby missile, which he got to work with using. He then activated the missile which blasted right through the security doors, allowing Ludo to proceed forward. At the end of the hall, the spider jumped down with Ludo and the eagle as they had reached their destination; the seventh security door was in front of them and Ludo felt the need to gloat for a second.

"Ha ha ha, piece of cake."

He looked towards the Level 7 Security door, which unlike the others, required a passcode to press on through. Using the one that was in his grandfather's diary, he successfully got the door to open as he entered with his spider and eagle.

"Oh ho," he gasped in awe as the giant spider approached some kind of a containment device that possessed the top-secret weapon he was dying to see. "So this is the military's top secret weapon? It's a lot smaller than I expected!"

He peered towards a monitor on the spiders' back as he then saw what it said.

"Enter user data…aha, enter the password," he typed in the password that was also found in the diary. "Password is 'VIC-TO-RI-A!' Victoria. Now all I have to do is to place this Miracle Gemstone into this console."

He took out the white Miracle Gemstone that he had in his possession; a gift that was given to him by his brother Dennis. Once he placed it into the console, the room suddenly got dimmer, and the containment started rising. Ludo jumped down with the spider and eagle to get a closer look. He saw a bunch of sparkling mists of electricity occur and was in complete awe at witnessing the containment reaching the top.

The last thing he expected was for what looked like a girl to pop out and fold her arms boldly while looking at the small Avarian.

"What the…? Is that you Star Butterfly," he bellowed. "Are you trying to spoil my plans again!?"

The girl did resemble the princess of Mewni to a large degree, but she was anything but Star. For starters this girl had dark purple hair with red streaks on both sides instead of blonde hair, two purple color neutron atoms on both sides of her cheeks replacing the two hearts, red color eyes instead of blue, and also wore a sinister looking purple skirt dress with a red shiny gem on the front; a contrast to the blue-green kind of dresses that Star usually wore. She also wore combat boots that didn't look anything like the boots that Star wore which the heels took the shape of some kind of monster, a pair of medium sized dragonfly wings which contrasted Star's butterfly wings, and finally, the girl had four golden bracelets on her wrists and ankles, which were fastened by red and dark purple cuffs.

Once Ludo took a good look, he did a double take and made the realization.

"Wait a minute, you're not Star Butterfly," he announced. "This is impossible!"

The look-a-like looked down towards Ludo and gave him a rather cold glare; a contrast to Star's typical cheery smile. The girl then decided to introduce herself to the Avarian.

"My name is Nebula; Nebula Dragonfly," the girl who was known as Nebula introduced. "Since you were so kind as to release me, my master…I will grant you one wish."

Before Ludo could question her about what she said, something else just entered the room as he looked behind him with the sirens going off again.

"Now what!?" He huffed in annoyance.

Nebula jumped right in front of him and had in front of her face what looked like a wand, which looked almost like Star's wand but was far more sinister looking, with a darker color coating and a creepy texture. The wand started flashing a purple aura as Nebula began to activate it.

"Behold the true power I possess!" She spun around and the wand did its job, as she teleported out of the pit and right in front of what had just entered the room.


The eagle picked up the giant spider and Ludo and flew up to the area that Nebula was in, and they saw that in front of her. It was a fighting mech twice the size of Nebula, with a military soldier piloting the machine, getting ready to fight.

"This is Centipede troops' Cold Blast. The enemy movement has been detected," the military machine had been sent to dispose of the intruder; aka Ludo, but was dealing with a different face. "En route to intercept and destroy!"

"Copy that!"

The Cold Blast then took to the air and started to hover around the room and started to shoot Nebula. Nebula was able to dodge the incoming bullets with ease and display good acrobatic combat skills that could be comparable to Stars'. The mech flew over her head and went to the other side of the fighting area.

"Witness my true power!"

Baring the wand in front of her, it then charges up some purple energy and then fired what looked like a dark purple laser beam towards the giant robot. The beam did a good amount of damage to the robot, causing the pilot to recoil from the impact. While Nebula repeated the procedure, Ludo was watching in shock at how Nebula was dealing with the robot.

"Her fighting displays are almost exactly like Star's, but her outlook definitely betrays that," he mused to himself.

Nebula stood upon a crate, waiting for the machine to head for her, just enough so she could then attack again.

"Hmph, pathetic," she then did a motion. "Let's try this: Dark Purple Fist Punch!"

She then fired what looked like a fist that's color dark purple to punch the cockpit of the machine, which looked identical to Star's Rainbow Fist Punch. Seeing how powerful the opponent was, Cold Blast decided to charge some particle beam cannon and fire towards the dark girl, but to no avail. Nebula then used other spells that worked as dark counterparts to the spells that Star uses with her wand.

"Wow, she doesn't just jump and kick the robot, she waits for the right moment to strike it with one of her spells," Ludo was getting excited. "She could be an even match for Star, outdoing any Cupcake Blast, Dagger Crystal Heart Attack or Mega Narwhal Blast that the princess of Mewni could dish out."

Ludo could already imagine Nebula fighting against Star and being an even match for her, trampling the Mewni princess and proving to be stronger.

With Nebula, she let out a scoff and launched a dark lightning strike attack from her wand towards the robot and made direct contact. The pilot of the Cold Blast machine was aware that the machine couldn't overpower this mysterious person and looked about ready to throw in the towel.

"This is Centipede troops' Cold Blast! The enemy is stronger than expected, request additional support!"

"No one can stand up to me!" Nebula bellowed as she took to the air, and went to deliver a spin kick towards the cockpit of the machine, making direct contact and dealing one final blow to the Cold Blast.

"SHE IS TOO STRONG!" The pilot cried out as the robot fell apart from some mini explosions with the pilot falling into unconsciousness minutes later.

"Pathetic humans," she scoffed and folded her arms. "There's no time to play games."

She then took a glance towards Ludo to see his reaction before turning her back on him.

"Destroying that guard robot was spectacular!" Ludo expressed his surprise towards Nebula's raw power.

"So Nebula, you are the military's top secret weapon," Ludo concluded as Nebula was lost in thought. "But what did you mean when you said you'd grant me a wish?"

Nebula only took a quick glance towards Ludo before being blunt with him.

"Bring more Miracle Gemstones." Nebula showed the white Miracle Gemstone that Ludo sacrificed just to release her from her containment towards the Avarian before she started to walk off.

"Nebula, wait a moment!" Ludo cried out to her, which she then stopped long enough to deliver these instructions with a smug grin of intentions crossing her face.

"I'll be waiting for you Ludo, in the central control room, on the Space Colony GOD located in the Space Dimension."

Ludo was bamboozled by what she said and leaned onto the spider's head. "G-GOD…? The Space Dimension…?"

Without another word, Nebula then left to put forth what seemed to be revenge planned 40 years in the making into action; something that Ludo knew nothing about. Ludo was left behind staring in shock and confusion before he found his voice.

"I wonder what she meant by the Space Colony GOD that's located in the Space Dimension," Ludo said to himself. "Well, I'll find out more about this space colony and space dimension soon enough..."

He then directed his attention to the giant spider and the eagle and informed them.

"For now, we should probably get out of here now, shall we?"

The spider and eagle screeched to show that they are ready to head out. Ludo then pulled out his dimensional scissors, cut open a portal, and the three of them entered the portal and left the area, with the portal closing behind them.


LATER THAT NIGHT, AT THE FEDERAL RESERVED BANK LOCATED IN ECHO CREEK:

In Echo Creek where the bank was located, there was a green Miracle Gemstone that was emitting a green glow kept in a glass cover for protection. Moments later, a shadow figure shaped like a female hovered right over it.

"…"

Without a single word, the figure punched through the glass, breaking it as she then grabbed the green Miracle Gemstone, causing the sirens to go off. By the time the figure made it outside, the security guards surrounded her. But a sinister grin emerged on the shadow's face, directed towards those in front of it. Holding what looked like a wand, the figure fired purple lasers at the guards, causing them to get knocked out cold. The other guards that tried to stand in the thieves' path got trampled and sent forward or were sidestepped, leaving them helpless to fight back. Several purple lightning bolts got fired towards the machines that stood before this robber. Once the figure escaped, the person responsible for stealing the gemstone hid in an alley and she had to lay low in hiding for a bit before making her next move…


END OF CHAPTER 1!

YUP, THAT'S IT FOR THE FIRST CHAPTER. THE ACTION IS JUST GETTING STARTED!

NOW LET ME SAY THAT UNLIKE THE PREVIOUS STORY I DID 'LOVE AND DUTY', THIS STORY IS A SOLO WORK OF MINE, AND ALSO IT WON'T TAKE ME 7 MONTHS TO COMPLETE THIS STORY! IT'LL TAKE LESS THAN THAT SINCE THIS IS THE KIND OF STORY I WANT TO CREATE!

NOW SOME OF YOU ARE CONFUSED BY NEBULA AND HER APPEARANCE AS THE TOP-SECRET WEAPON, BUT MORE ABOUT HER BACKSTORY WILL BE REVEALED AS THE STORY GOES ON, SUCH AS HOW SHE WAS CREATED AND ALL THAT STUFF! AND AS FOR THE FACT THAT HER ATTACKS ARE DARK COUNTERPARTS TO STARS' SPELLS, THAT WAS INTENTIONAL TO MAKE NEBULA THE COMPLETE OPPOSITE OF STAR. THE ONE MOTIVE BEHIND THIS WAS TO MAKE A CHARACTER WHO IS A LOT LIKE STAR IN TERMS OF APPEARANCE AND ATTACKS BUT IS THE STARK CONTRAST TO STAR'S OVERALL PERSONALITY, SIMILAR TO SONIC'S OPPOSITE COUNTERPART IN THE FORM OF SHADOW IN SONIC ADVENTURE 2. THIS WILL BE EVIDENT IN THE LATER CHAPTERS WHEN STAR AND NEBULA ENCOUNTER EACH OTHER FACE TO FACE. I LOOK FORWARD TO DEVELOPING THAT TOO!

ANYWAY, NEXT CHAPTER, THE OTHER NEW CHARACTER WILL BE INTRODUCED WITH THE RULER GEMSTONE, ANOTHER CHARACTER FROM THE SHOW ARRIVES IN THE OTHER NEW CHARACTER'S DOMAIN TO TRY TO STEAL THE RULER GEMSTONE BEFORE A CONFLICT HAPPENS RESULTING IN IT GETTING SHATTERED, AND OH YES, STAR WILL BE INTRODUCED AND BE ON THE RUN FROM THE FBI AND MILITARY WHO WANT HER FOR A CRIME SHE DIDN'T COMMIT. HOW WILL THIS ALL GO? FIND OUT NEXT TIME, READERS!

FOR NOW, ONLY IF YOU LIKE, YOU CAN LEAVE A REVIEW AND TELL ME WHAT YOU THINK OF THIS SO FAR, OR YOU CAN PM ME AND LET ME KNOW WHAT YOUR PERSONAL OPINION ON IT IS! BE FAIR AND EASY ON ME SINCE THIS IS MY FIRST STORY FOR THIS SERIES AND IT'S A FIRST ATTEMPT.

OTHERWISE, THAT'S ALL I GOT FOR NOW! I HOPE YOU LOOK FORWARD TO THE REMAINDER OF THE STORY AND TAKE CARE UNTIL NEXT TIME READERS!
