Sonic the Star in Adventure in Mewni 2


Chapter 5 - Janna?


The Solarian Base, New Mewni


"HOW COULD YOU TWO FAILED!" shouted Solaria at Manfred and a hologram of Fang while being watched by Eggman Nega who have just return from Mobius in the command center of the Solarian Warriors' new base of operations built within a mountain at the center of the Solarian Forest called the 'Solarian Base'. This based was built from parts from with Eggman Nega supplies and salvage parts from the abandoned Neo Scrap Brain Zone.

"But my queen, that red rat of a echidna shattered the Master Emerald into piece which I informed Fang of." said Manfred as he pointed at Fang which the hologram showing him repairing his hoverbike, the 'Marvelous Queen', as both he and the hologram stand behind a window that show a view of the Solarian Forest which the city of Echo Creek can be seemed in the distance as Fang spoke up.

"It's not my fault miss Solaria, but that bat girl managed to us my own missiles against me, since 'someone' didn't inform me of her and the ENHIDNA and stop called us mobians as rats, pudding face." referring Manfred a 'pudding face' which made him mad for a creature like Fang called him like that out loud with no respect at all and the mewman and mobian began arguing at each other to which Solaria have enough and shouted in a commanding voice.

"SILNCE" Manfred and Fang stopped arguing at focus their attention on Solaria

"I don't care about this 'Rouge the Bat' or that our enemies now know we're working together." she was referring to Eggman Nega for revealing himself to Star and Marco who also heard about the Master Emerald breaking into piece and told her how the shards can still be use for their plans on 'retaking Menwi', and continued "Luckily our Chaos Emerald dimensional radar can also locate those emerald shards, we already located 3 shards in north of the Solarian Forest and 3 more in what remains of Neo Scrap Brain Zone and sending squads to get them. I have Mina get ready to go to Mobius to pick up on the shards from a place called 'Speed Highway' and right now Eggman Nega is going back to Mobius to get a Chaos Emerald in Aquatic Ruin Zone. So, I need Manfred to stay here to oversee preparations for tomorrow while I'll go with Eggman Nega as support, and I want Fang to go to Speed Highway since radar picked up a Chaos Emerald on the move which means someone has an emerald in their hands."

"But my queen-" Manfred began to protest but Solaria interrupted him with a shout

"DO I MAKE MTSELF CLEAR WARRIORS?!"

"SIR YES SIR...I MEAN MA'AM" saluted Manfred

"Fine Miss Solaria, as long as I get paid of course." answered Fang. Then his hologram disappeared and Manfred ran out of the command center to oversee preparations. Then she turns to face Eggman Nega and said to him

"I still can believe you're having MY Solarians all over New Mewni in search for shards, why do we have Fang to search for them while he's getting paid to look for Chaos Emeralds?"

"You may not believe, but Master Emerald is one of many countless artifacts in our universe beside the royal butterfly wand, even broken into shards still possess a great power, power that can control all seven Chaos Emeralds and power that can be uses for my greatest creation yet, Egg Gloomfly."

"If you said, I know that Star still possess the royal wand, and I plan on taking it back from her and sent a message to any other traitors of mewman kind that we Solarians do allow mewman support of monsters. Plus, I never been on an alien planet before, so this is a whole new experience to me."

"Huh, I didn't know this would be your first trip to an alien planet, well good for you I guess." said Eggman Nega as he and Solaria walked out of the command center for their mission.


Mystic Ruins, Mobius


It wasn't easy for Tails to keep the Tornado in the air due to Star and Marco's human weight while that hang on to the wings of the plane because the plane itself has two sits and both Tails and Amy are using it, and Sonic is standing on top of the plane, making it a slow trip from South Island. But they finally landed at Tails' Workshop in Mystic Ruins. As the plane finally came to a stop on the runway and the engines turned off, Marco climbed off the biplane's left wing and began kissing the ground in relief while Star jumped off the right wing and excitedly cheered.

"HAHAHAHA, WE MADE IT, LET'S NEVER DO THAT AGAIN, WAY TO DAUNGEROUS EVEN FOR ME!" shouted Marco.

"Agreed" said Tails agreeing with Marco as he, Sonic, and Amy got off the plane as well while Tails was thinking he should have got out his stronger biplane the 'Tornado 2' and then check on the Tornado for any damaged of any kind worrying for the biplane since Sonic gave him the Tornado which used to be his biplane back when he and Sonic first met. To Tails' relief, the Tornado didn't develop any problems or damaged from Star's and Marco's weight during the flight as he knows that this biplane survived far worse.

"OMG, this is your workshop, Tails?" asked Star in amazement as she stares at Tails' Lab or 'Tails' Workshop' as Sonic pointed during the flight from South Island. The workshop is a large hanger with Tails' twin tail symbol on the hanger door, with a separate small apartment on the top, and a generator rotating next to the workshop.

"Sure is Star, here is where I make my gadgets and inventions like my M.E.D.E.L device that allow us to visit your world for the first time." said Tails as he put out a remote with one red button on it, then push the button to open the hanger door to reveal the hanger interior with has a small laboratory at the back of the building, a set of stairs that lead up to a catwalk which lead to a door to Tails' apartment where he lives in. In a large open room on the side on the first floor near the hanger door is another biplane parked which looks like the Tornado, but with a blue and yellow color scheme instead of red and gray and look more upgraded with Tails' symbol on both top wings and vertical stabilizer, but both biplanes have the word 'SONIC' in white written on the fuselage.

"So this is where made that device about allow you to come to New Mewni without dimensional scissors?" asked Star as she rushed inside while Sonic, and Marco help Tails, push the Tornado into the hanger as Amy asked, "Dimensional scissors?" which Marco answered as he pushes the plane into the hanger. "It basically magical scissors that create portals, sounds dangerous when running around with but they were effective when traveling to planets or even other dimensions before Star has to destroyed Mewni's Realm of Magic which that's a long story for another time."

"Which I still think that your Realm of Magic should have a Guardian to watch over." said Knuckles holding three emerald shards in hands, catching everyone off guard turning to face him as he continues "Hello Star, hello Marco, I'm surprised to see you two here on Mobius."

"Hey Knuckles what beings you here?" greeted Sonic as Knuckles raise and open his hand to show the shards to them.

"Oh man Knuckles, how did the Master Emerald break apart this time?"

"Wait, the Master Emerald broke apart?" asked Star, then Knuckles replied, "It's a long story Star, but this is not the first time, and I can restore the Master Emerald when I gather all of its shards, I already found three shards in Sky Sanctuary and six other shards in Windy Valley and in Lost World underneath the echidna temple ruins, that's when I saw the Tornado. Also Star I should let you know that someone from the Solarian Warriors try to steal the Master Emerald which I have to destroy the Master Emerald to stop that from happening."

"Did you say 'Solarian Warriors'?"

"Yes, he did mention 'Solarian' and from what you told us about the Solarian Warriors from our first adventure on your planet, I figured that maybe Eggman is cause trouble to your world again and could have team up with the Solarian Warriors?"

"You're halfway right knuckle head, but this time its Eggman Nega." said Sonic. Then Sonic and Marco explain to Knuckles about the current situation while Star go over a whole lot of messages left by her family and friends who used Star's communicator that's linked to Tails' computer in his laboratory who she sent a message of her own to saw to everyone back home on what happened and say that she and Marco are safe and sound and are with Sonic and his friends. She also warned her friends and Family about Mina and Eggman Nega in the message too and Star hopes they got the message. Then as she finished and sent her message, Star noticed Tails walked up to her with his M.E.D.E.L device in his hands.

"Hey Star, have you got your message sent?"

"Yep, and I can tell that you got some news to share?"

"You bet I have. I just upgraded my device so we can locate the Master Emerald Shards and already located 3 shards in the other end of Speed Highway at Station Square. I also found a Chaos Emerald moving around in Station Square too and another Chaos Emerald in Aquatic Ruin Zone."

"Already? Darn Tails, you're on a roll."

"Thank Star, I'm going to tell Sonic and Knuckles, if you want, you can tag along to see what we're planning to do next?"

"You don't have to tell me twice, plus I just got done and sent everyone back home a message, hopefully they'll get it."

"I sure they'll get your message Star."

A few minutes later, after Tails told Sonic and Knuckles about the emerald shards and Chaos Emerald locations. Our main heroes gathered in the hanger to see what to do next.

"I know Sonic is fast, like supersonic fast, but even he can't be at two places at once."

"You're right Marco, so I think we can separate into two teams while one goes to Station Square and help Knuckles find the shards while the other goes with me to Aquatic Ruins Zone and grab the Chaos Emerald." explain Sonic then turns to Tails and asked if he could come with him to Aquatic Ruins Zone?

"You bet Sonic. We can take the Tornado 2 to West Side Island and reach Aquatic Ruin Zone."

"Came I come with you two, I still want to kick Eggman Nega's butt if he does appear again" asked Star who is still mad at losing a Chaos Emerald to Eggman Nega in Green Hill Zone earlier and want to get answers from him on his and Mina's plans for New Mewni. Then Tails answered

"I guess Star, luckily the Tornado 2 is stronger and faster, and I don't think the Tornado won't last another trip supporting Star's weight, no offense Star."

"None Taken."

"Hey what about me guys?" cut in Amy "What am I chopped liver? I want to help too." then Marco replied, "I guess you and I could with Knuckles to Station Square, if that's ok to you Knuckles?"

"Normally I would not ask for help since I'm capable to locate the shards on my own, but I own you one for helping me find the Master Emerald when those Septarians stolen it and took it to your world, plus I know Amy for a long time as her friend, so sure I don't see why not."

"Oh thank you Knuckles." said Amy as she grabs both Marco and Knuckles to hug them as Knuckles added "Just don't get in my way too much please. Plus I think I know who have that Chaos Emerald in Station Square and Diaz, she is a friend of yours, Janna is it?"

"What?'


Station Square, Mobius


Meanwhile in the Station Square Chao Garden, we unexpectedly find a teenager with short dark-blue hair and brown eyes and wears an olive-green shirt, a turquoise jacket, a yellow skirt, brown boots, and an olive-green beanies hat. Her name is Janna Ordonia, a friend and Star Butterfly and Marco Diaz who is into things of the paranormal, that now includes the Chaos Emeralds who she has one white Chaos Emerald in her olive-green camo colored backpack. Two months ago, she found the Chaos Emerald in the sewers of Echo Creek and accidentally turned Chaos Control which teleported her to Angel Island right in front of Knuckles and the Master Emerald. Since then, she learned from Knuckles, who she convinces him to keep it a secret, and been secretly teleporting between New Mewni and Mobius and learned more about Sonic's world. Most recently she been visiting the Chaos Garden in Station Square, which the garden itself is home to cute mystical creatures called 'Chao'. Normally she rarely cares for cute things unless it's from Star, but she kind of grew to like these waterdrop shaped creatures and often help the staffs who work to maintain the garden. Since Mobius also have a native human population alongside with the anthropomorphic mobian population, Janna can blend in with any human crowds to draw less attention.

She just left the Chaos Garden and exit the building into the city and noticed a green gem shard behind a lamppost next to the Train Station.

"Oh sweet." said Janna to herself as she picked up the shards and as she opens her backpack to place the shard inside, she noticed both the white Chaos Emerald and the shard began to glow, reacting to each over. "What the? What's causing the Chaos Emerald to glow like that, maybe I should take it to Knuckles before I go back to New Mewni?" Jana asked herself as she close the backpack and added, "But first I should visit Speed Highway, I would like to see what crazy architecture they have there, since most places of this world seems to look like something out of a video game with all those loopy loops and floating platforms." That's when she spotted the red Echidna with a pink hedgehog in a red dress and a familiar face.

"Diaz?"

"Janna? So you are here on Mobius!" Marco said to Janna a very angry at her. Then Janna turned Knuckles and spoke to him. "Dude, I thought we agree to keep this a secret, also why are you here Marco?"

"It's a long story Janna, but you world is in danger again." said Knuckles and after introducing Amy Rose to Janna and explaining what's happened recently, Janna would understand and decided to help them since she was heading to Speed Highway herself as she show Knuckles the emerald shard she found not too long ago and gave it to Knuckles along with her Chaos Emerald knowing that they may need the emerald later, but then Knuckles hands the Chaos Emerald back to Janna and said.

"I think it's best that you should continue to hold on to that emerald until we meet up with Sonic and the others." then our heroes began going towards Speed Highway, unaware of Fang who is watching and following them from a distance, waiting for his chance to strike.
