Note: Star vs the Forces of Evil belongs to Disney and Sonic the Hedgehog belongs to Sega. I don't own anything. This is my very first fanfiction, so my writing is not 100% perfect. Now with that out of way, let's continue the story where we left off. Also there will be a reference of Star Wars the Clone Wars and My Little Pony in this chapter
Sonic and Star in Adventure in Mewni
Chapter 8 "Super Star" vs the Forces of Evil
"HAHAHAHAHA, Now Sonic the Hedgehog, my admirable adversary, prepare to be destroy." Yelled Dr. Eggman as he launched the Death Egg Robot's retractable arms at Sonic who which quickly dodge but can't attack. With Star's wand, the Master Emerald, and Eggman's 6 Chaos Emeralds, the Death Egg Robot is invincible, he can't damage it at all. Meanwhile Tails, Star, and Marco, who are trapped in between two force fields at the metal altar, can only watch Sonic trying to fight Eggman's mech while Knuckles decided to try to punch his way out to reach the Master Emerald, even though the force field protecting the emerald is stronger, the Guardian of the Master Emerald won't give up.
"We can't just do nothing guys" said Star, "we need to help."
"But how?" asked Tails, "this room is jamming the M.E.D.E.L so we can't teleport out of this." But then Star remembered something about the Chaos Emeralds on how they have the power to turn thoughts into power.
"Maybe we don't use M.E.D.E.L, what about the Chaos Emerald, the one I gave you when we first met today? Did you and your friends that the emeralds have the ability to turn thoughts into power?"
"Yes but...oh I see what you're planning. It's risky but I think Chaos Control from the emerald will allow you to teleport out of here and to the Master Emerald." Then Tails pull out the white Chaos Emerald and gave it back to Star, then whispered to her how to properly use Chaos Control, "and take Knuckles with you, he's the only one who can use the Master Emerald to stop the Chaos Emeralds." Star with Chaos Emerald in hand, turn to Marco and told her boyfriend about her plan. "Good luck Star." said Marco and gave Star a quick kiss on the cheeks before Star rush beside Knuckles and whispered to him the plan.
"Well I guess we have no options, Sonic needs help." then Star grab hold of Knuckles and followed Tails' instructions. She closed her eyes and imagined herself and Knuckles outside of the force field and near the Master Emerald in her mind as hard as she could and shouted "Chaos Control" suddenly a flash a white light covered Star and Knuckles and seconds later Star open her eyes and saw that her plan work, she and the echidna are on the other side of the second force field and near the Master Emerald.
"You did it Star" shouted Tails and Marco.
"Ok Knuckles it's up to you, Tails tell Sonic that help is on its way in the form of the Master Emerald." Knuckles rush up the metal steps of the fake altar and reach the Master Emerald. Then Knuckles clear his mind.
"The servers are the 7 Chaos. Chaos is power, power enriched by the heart. The controller is the one that unifies the Chaos."
The Master Emerald began to glow a bright green aura, and its energy began to take effect. The force fields began to flicker as if losing power and the modified Death Egg Robot started to malfunction.
"WARNING DEATH EGG ROBOT LOSING POWER." Said the mech's cockpit computer.
"What? What's happening? I'm losing my connection to the wand and the...NOOOOOO."
"Master Emerald, only you can stop the wand which your energy flow through along with the Chao Emeralds."
suddenly the Master Emerald shot a green beam of light into the air and glowing so bright everyone has to cover their eyes from the brightness. The Master Emerald's energy created some kind of EMP that only affected the whole room, force fields, Death Egg Robot, the 7 Chaos Emeralds and the wand. seconds later, the Master Emerald stopped glowing and everything went silent for a moment as if time as stop.
Tails reach out for the force field to discover that the force fields are gone and our heroes hear machines shutting down. The Death Egg Robot has been deactivated and Sonic noticed it and took his chance to attack as hard as he can and finally damage the mech and hitting the panel which held the 6 Chaos Emeralds and the wand, with the fight force of power to break open the panel and the wand and the 6 Chaos Emeralds fell out as the mech itself topples and fell backwards to the metal ground while Sonic using his speed to grab the wand and the 6 emeralds and ran towards his friends now free from the force field trap.
"NNNOOO I CAN'T BELIEVE THIS." Shouted Eggman unable to restore power to his mech. Then push the eject button which automatically blew off the Death Egg Robot's head in order for Eggman in his mobile to escape, but his mobile also lost power so it can't fly and forced Eggman to climb out, only to face Sonic, Marco, Star with wand in hand.
"Eggman, you are done?" Said Sonic as he grabs Eggman's arms to prevent him from escape as Star look around and asked "What's Seth?"
"I don't know, I called him earlier before you show up, but he didn't answer."
"Guys." Shouted Marco to draw their attention. Star, Sonic, and Eggman turn towards the metal altar to find Seth defeated Knuckles and push him off the altar, luckily Tails caught him just in time. Sonic, Star, Marco and even Eggman rush besides Tails and Knuckles to see what's going on.
"Finally," hissed Seth standing beside the Master Emerald, "with this, revenge will finally be mine."
"So you have you own agenda after all." shouted Eggman "I knew you couldn't be trusted."
"And yet you did anyway you stupid egghead, you see I don't want a super solider army, I want to wipeout all mewmans and any human, monster, or even mobian that stands in my way and my Septarian Warriors' revenge."
"Wipeout all mewmans?!" Star shouted, "you still want to harm all mewmans for what happen so long ago? Seth those days are gone, and the mewmans has change and see monster as equals."
"It's too late for that, just because you destroy the Realm of Magic to save your friends doesn't change the fact that your people, the self-proclaimed noble mewmans take everything you see ever and destroy anything that is not look like mewman since your kind appeared on Mewni. Justice must be served, and now that day have finally come." Then Seth hopped on top on the Master Emerald.
"HEY GET OFF THE MASTER EMERALD YOU LIZARD!" Shouted Knuckles, but before anyone could stop Seth, a golden light cover all over the Septarian leader and seconds later disappeared, revealing Seth in a new golden form hovering over the Master Emerald.
"Oh no, Seth knows how use the Master Emerald to gain a super form?!' cry out Eggman in fear. "A super form?" asked Marco as Seth shot a golden laser from his fingertip at the Death Egg Robot, right over our heroes, and destroyed it. "Never mind. I get the idea." whispered Marco.
Things went from bad to worse.
Seth, now in his new super form, use his newfound supersonic speed and punch Star, launching her in mid-air and crash into what's left of the Death Egg Robot and fell unconscious with wand still in her hand. "Star" yelled Marco as he rushes to her. Sonic mad at Seth after what he did to Star, yelled, "ok Seth that's taking things too far, just because you're mad at Star's people for what they did centuries ago, doesn't give you the right to destroy them, She told me all around Mina Loveberry and you are no different to Mina in fact you're just a horrible, inhuman, cruel, TYRANT!"
"You, you mobians shouldn't have got involved, once I do this universe a favor and destroy all mewmans and take over New Mewni your world is next, once will sent my armies to invade Mobius and make your people suffer, I meant what I said about anyone that stands in my way and with the Master Emerald and soon the 7 Chaos Emeralds, the Septarian Army...no the "Septarian Empire" will be unstoppable.
"I can tell you have done your homework to gain that form, and you should know already that I too have a super form too." suddenly the 7 Chaos Emeralds appeared out of nowhere in mid-air and circling around Sonic. Then the hedgehog fused with the emeralds and became Super Sonic, his blue fur became gold, and his green eyes became red and gain to hover off the ground. Then without waring Super Sonic appear in front of Seth in hyper speed and upper cut the golden Septarian which launch him literally through the dome roof and the upper levels of the until he broke through the final roof back outside leaving a large hole in the Central Building that lead back to the Master Emerald Generator Room. Suddenly Super Sonic appeared out of nowhere and charge towards Seth which the Septarian did the same and the crash between two emerald powered super beings began right in the skies above Neo Scrap Brain Zone.
Back to our other remaining heroes, Septarian Warriors began to pour into the generator room and charge towards Tails and Knuckles as Eggman ran away back to his Egg Mobile that survived the Death Egg Robot's destruction and got out a hidden radio. "It's another trap." said Knuckles as the red echidna and Tails rush towards the warriors and begin knocking them down one-by-one. Meanwhile Eggman finally got the radio on and yelled into it.
"This is Eggman to all of my robots, the Septarian Army has doubt-cross us, all Septarian Warriors are now enemies, I repeat all Septarian Warriors are now enemies." Then Eggman climbed back into the mobile and managed to restore power. Now off the ground, Eggman rise his mobile higher in the air and push a button, which lower down a brown, checker pattern wreaking ball attached to a chain connected to the mobile and fly over to join Knuckles in battle. "YOU HAVE A WREAKING BALL WITH YOU?!" yelled Marco as he saw Eggman flying by with the wreaking ball in tow as he stayed closed to a unconscious Star, trying to get her to wake up.
Meanwhile in Star's unconscious mind, the former magical princess of Mewni woke up in a room with tapestries that show the past queens of Mewni, which she recognizes as she regains her sights.
"What...the Grandma Room? How did I get here? Wasn't I in Neo Scrap Brain Zone?" Star stood up as she spots her tapestry which show her in standing as she is destroying the magic as her parents, Ecplisa, Globgor, and every monster behind her with a forest and the Monster Temple in the background along with 3 of Mewni's moons in the sky. The last time she saw that is when she convinces herself to destroy the Realm of Magic to save everyone from Mina Loveberry.
"Oh this bring back memories, and that was 3 weeks ago."
"Oh yes it does bring back memories." Said a familiar voice from behind her and turn to see a small dark-blue humanoid wearing a yellow tunic and belt with a pendant. He has a white beard in the middle, a magenta gem embedded in his forehead and has pink lips and pink eyes and is floating in the air in a meditation stance. "Hello Star, it's been a while." greeted the small man as he waves his hands revealing six fingers on his hand.
"Glossaryck?! Ok this must be a dream?" asked Star which Glossaryck replied "actually, you're in a subconscious dream, Seth really knocked you out good and if you're wondering, your friend Sonic is battling against Seth in his own super form called 'Super Sonic', Eggman has just ordered his robots to fight the Septarian which some of those Septarian are fight Tails, Knuckles and even Eggman while your boyfriend is standing beside your unconscious body trying to wake you up by the way.
"Unconscious body...now I remember, but wait, if my body is still in Neo Scrap Brain Zone, then why am I here? I need to wake up and help them stop Seth."
"Now slow down Star, I'm afraid it going to take more than karate and Super Sonic to take down Seth, with the energy of the Master Emerald combine with Seth's natural regeneration, that Septarian as become invincible and Sonic's super form won't last forever, the reason why we brought you here in your mind is because you need to know how to uses the Master Emerald, you need to use magic again to save the day."
"Use my magic, but I destroyed the Realm of Magic and...'we'...what do you mean by 'we'?"
"Oh Star Butterfly, the magic you use is still in you." said a sweet, unfamiliar voice as a orb of bright pink light descended from nowhere and hover around Star. "Star Butterfly, met a spiritual friend of mine, the one who seal the original guardian, Chaos, in the Master Emerald after her clan attack the altar back on Mobius in ancient times. Tikal." Glossaryck introduced Star as Tikal transform from a light orb into a echidna with peach-orange fur, black nose on her peach muzzle. She has cobalt-blue eyes with two medium length eyelashes, dreadlock like spines around the sides and back of her head just like Knuckles. But unlike Knuckles, she wore tribal clothes and wore a golden necklace and a tiara like band atop her forehead.
"You see Star, unlike Sonic who draw the energy from the Chaos Emeralds, Seth is drawing his power from the Master Emerald which is stronger and powerful then the Chaos Emeralds their selves."
"Which means, Seth is more powerful than Sonic, but what those that have to do with my magic?" asked Star to which Tikal answered. "Well, let me put it this way. Magic doesn't just come from a Realm of Magic, it's a energy a field created by all living things. It surrounds us and penetrates us; it blinds us together."
"So what's you saying that I don't need the Realm of Magic to use magic?" This makes her concern. Her family back when they were royalty, they try to use magic to solve problems but only make things worse. What if using magic again will make thing even worse.
"Oh Star" began Glossaryck "I can tell you're concern, and I can understand. But Star, you have the biggest heart anyone have ever see and right now your friends need your help more then ever now and you'll need the Master Emerald to use your positive energy to defeat Seth's negative energy. I know you can do it."
Star think it over and remembered how much she have change since first meeting Marco and agree with Glossaryck, she does have a big heart.
"Ok, please tell me how to use the Master Emerald."
Back in reality, the fight between Super Sonic and Seth above Neo Scrap Brain Zone as they witness explosions happening all over the Zone as Septarian and Badnik armies turn on each other.
"Well Seth, it seems your army bit more then they could, that way have when you doubt-cross Eggman." Seth only hiss at the hedgehog and kick him.
Meanwhile back to Maco, Star has finally woken up and quickly got back up. "Wh...what happened."
"Star, you're ok" cried out Marco and gave her a hug. "Ok I enjoy the hug, but right now Marco, I got a plan, and we can thank Tikal and Glossaryk for their help."
"Wait what those Glossaryck have anything to do with our situation and who is Tikal?" asked Marco.
"Wait, you met Tikal? When?" asked Knuckles as he holds a Septarian in the neck as he constantly punching the lizard in the face. "Oh now, Glossaryk was right, everything went into chaos since I got unconscious."
"That's the usual shenanigans to us at least." replied Marco as he and Marco watch Tails using his gadgets to support Eggman as his Egg Mobile has ditch the wreaking ball for an small cannon attached at the bottom and shooting fireballs at some Septarian lizards while Knuckles throw the Septarian he was holding at another Septarian knocking both of them out. Then suddenly Sonic crash through the hole he made earlier into the ground but quickly to avoid an attack from Seth.
"Marco, there's little time to explain, but I need to reach the Master Emerald."
"The Master Emerald? But why?"
"Because I could use the energy of the Master Emerald to restore my powers and stop Seth."
"Your powers, but you destroyed the..."
"Yes I know, and I'll explain once this is all over, but you have to trust me."
Marco was hesitant at first, but he smiles and said, "ok let's do this."
Star and Marco got back on their feet, got into their fighting stands and rush into the chaos of a fight. Knuckles was closest so they ran in and help the overwhelmed echidna and gave him some fighing support and defeat 8 Septarian Warriors. "Thanks" shouted Knuckles as they continue fighting their way to the metal altar. Finally, they went up the metal steps to the Master Emerald and then Star climbed on top. "Are you sure this will work Star." asked Marco and Star replied, "I'm sure Marco and you may want to step back."
As Marco quickly went back down the steps, Star did what Tikal told her "Clear my mind and ask the Master Emerald for help" she whispered to herself. Then she closed her eyes, raise to wand in front of her with two hands and image asking the Master Emerald for help as she spoke the prayer Tikal told her, the very same one Knuckles used earlier.
"The servers are the 7 Chaos. Chaos is power, power enriched by the heart." then the Master Emerald begin to glow a green aura just like before and not just too far from the altar both Sonic and Seth began to feel the effects of the Master Emerald and turn to find Star standing on top of the giant green emerald pointing her wand at Seth. "NO" yelled Seth as he flies towards Star but suddenly lost his ability to fly. The same go to Sonic as the 7 Chaos Emeralds reappeared around him and began floating towards turning back to his normal self. The glow from the Master Emerald made everyone else stop fighting to see what's going on.
"The controller is the one that unifies the Chaos." Star's wand began to transform from the form when Marco held it last back into the first form it took when Star first held the wand as a golden glow centered at the wand. "Master Emerald, I need your help, help me take back what belongs to you from Seth." the Master Emeralds glow as bright as it sent its energy into the wand while the wand drains Seth's of his newfound powers he took from the Master Emerald."
"NO, MY POWER NO." yelled Seth as all of his power was drain and went into Star's Wand as Star transformed, golden wings appear, her clothes' colors turned white and gold and she opened her eyes revealing her blue eyes turned green as the 7 Chaos Emerald float around her, lending her their power.
"SUPER SONIC EMERALD BLAST" shouted Star as she unleashes and giant green and gold energy laser at Seth as Sonic quickly dodge it. "NONO NNNNNNNOOOOOO" yelled Seth as his body get disintegrated from within the laser just like Toffee when Star uses something similar. A minute later the laser began to get smaller and smaller then finally the laser finally disappeared as everyone stare in shock and awe. Star began to transform back to her normal form, her golden wings disappeared and her clothes' white and gold color scheme changed back to it's original colors. Then Star collapsed on top of the Master Emerald as the 7 Chaos Emeralds dropped in mid-air to the ground surrounding the giant emerald. The spot where Seth stood is replaced with a giant hole in the wall, bigger then the one Sonic made earlier showing the outside of Neo Scrap Brain Zone. Seth is dead for real this time, and unlike Toffee, nothing remains of the Septarian Leader.
"I don't believe, Seth...his gone." said one Septarian. The whole Septarian Army lost their fighting spirit to continue and flee from Neo Scrap Brain Zone. "You did Star." cried out Marco as he help the weaken but still conscience Star down from the Master Emerald and noticed that Star's wand changed back to it's first form. "Star...did you just use magic?"
"Yep, it's turned out I never lost my powers." she answered as Knuckles rush up and grab the Master Emerald off of the metal altar to make sure that no one else is waiting for a surprise attack out of nowhere. "Finally the Master Emerald is safe, now I can return it to my island back on Mobius. Hey...where's Eggman?" everyone turn to Tails who was now next to Sonic, since he was with Eggman during the fight against the Septarian "I flew to Sonic when Star shot that crazy laser at Seth to see if he's ok." explain Tails as he and Sonic climbed up the steps to met Star and Marco. "Here must have escape."
"Indeed I have." Eggman's voice and be heard through hidden speakers. Meanwhile in a secret room hidden somewhere in Neo Scrap Brain Zone, Eggman in his Egg Mobile activated a secret portal gate that leads back to Mobius. "You have won for now," continue Eggman talking in a microphone "But you have not see the last of Dr. Eggman, I'll see you back on Mobius Sonic the Hedgehog. That's go for you too Star Butterfly, we'll meet again." then Eggman put down the microphone and piloted the Egg Mobile through the portal back to Mobius an as it closed the portal gate self-destructed to prevent his enemies from following.
Back to our heroes, they walk down the steps of the metal altar, knowing that they're too late to stop Eggman from escaping. "I'm sorry that Eggman got away" apologize Star to which Sonic replied as he helped Marco carry Star down "Don't apologize Star, the important thing is we stop them from carrying out their plans, get the Master Emerald and Chaos Emeralds back and save both of our worlds, I think we did enough, and I think Eggman will leave your world alone for now."
"Hey Star, your wand looks different somehow?" Tails noticed the wand and asked Star about it to which she took a look for herself. The wand is now light purple with white wings attached to the grip. The bell of the wand has a blue circle with a gold star and pink hearts surrounding the crystal star inside. A yellow crown on the tip of the wand, a blue butterfly between the bell and grip and a yellow tip with a blue heart at the end of the grip. "Hey this is the form the wand took when I first held it." said Star in amazement. "I wonder if that she said is true?"
Then Star raise wand in the air and yelled "narwhal blast" Suddenly a bunch of small narwhal shot out of the wand and disappeared, leaving everyone in shock. "Tikal was right, there was a chance that could happen." everyone stare at Star in confused
"Oh come on you guys, have you never see a spell involning with narwhal before spoke up Glossaryck from behind and scare our heroes as they turned and face him.
"WHO THE HECK ARE YOU?" yelled Tails then Glossaryck replied "who am I, well Tails, I am Gossaryck...of terms, and I know all about you Sonic the Hedgehog, Miles, "Tails", Prower and Kunckles the Echidna the guardian of the Master Emerald. I also known that Globgor is here with a few of Star's friends and King Pony Head are about to come through that hole that Star made."
Suddenly as Glossaryck predicted, Globgor climbed through the hole from the side of the building carry Janna, Buff Frog, and even Star's dad River Butterfly on his shoulders following by King Pony Head and princess Pony Head flying in and began screaming that the top of their lungs ready to fight with makeshift weapons as they noticed that the final battle has already ended and they all stop scream and lower their weapons.
"Wait hold on...the battle is over? Already?" ask the so-called prince of darkness as he got Star's other friends and dad off his shoulders and shrunk down to human size. "Yeah, pretty much. What are you guys doing there?" asked Tails and added "and you must be Globgor, Star and her friends told us all about you."
"Well Tails, we came here to help you. Pony Head told us where you went and Janna has a tracking clip in Marco's jacket, the Septarian and Robots were fighting each other when we got here and fought our way to here, by the time we reach the center, the Septarian Army were already in retreat, running to all directions and we already took care all of the robots it was so exciting." explain River with spear in hand which could explain why they look like they been through a huge fight while Marco panicked and yelled "THERE'S A TRACKING IN MY JACKET?!"
"Well, we appreciated your help guys, but we already taken care of it." appreciated Star as Janna spoke. "Aww man I was hoping to see the finale and this that Glossaryck?"
This is the longest chapter I ever written due to that this is the final boss fight. Star vs the Forces of Evil belong to Disney and Sonic belong to Sega. I don't own anything. once again this is my very first fanfiction so my writing is not 100%. But the story is not let over. Until the next chapter and maybe the last chapter.
