Black Star : Falling Stars

Prologue

(Go City, Ten Minuets after Ultimeca's Defeat)

They had seen Azula, Juri, and C. Viper escape into the portal that took them to Azula's home world. Before that Morrigan had escaped with Blackfire. The world had been saved by Team Go's untapped powers of the comet. Now they stood there looking as the portal shimmered before them.

Kim looked at the portal, her crimson hair followed around her head. Glancing over she looked at Shego, her skin now pale since her powers seemed to have left her. Kim also had lost her powers, powers she had been granted when she had died at the claws of XeYori. Shego had tried to save her life, and it had worked, with the added side effects of the white plasma.

The plasma wouldn't even had been if it wasn't for the genetic enhancing serum the Doctor Cortez had her injected with on Isla Sorna. It had enhanced her strength, speed, regeneration, and intelligence. That was the island, the island full of dinosaurs where things had been uncovered.

It was an eye opening trip for Shego. She had gone there looking to save Kim from the mad man. She had uncovered more then she had ever thought. She had developed a new found friendship with a young woman named Tiara Lockheart. Though for her, discovering her true feelings for Kim were found out by a man. If that man hadn't come into Shego's life, she'd have never figured out her feelings for Kim.

The man went by the name of Jacob Matthews. He was a former Navy SEAL, on that island for one reason and one reason alone. He was out for blood. He had lost his true love, Lex Murphy, killed by the same man who had captured Kim. He became Shego's best friend, being close with one another. They had become practically family, since he had lost his.

Then Jacob had been approached by Blackfire, and Black Star an organization that Doctor Cortez had been a part of. He was offered a chance to reclaim his lost love Lex. He had to do one thing he hated and still hates himself for. He had to turn on Kim and Shego. Along the way he had to do some dastardly things to them both. Finding out they never had Lex nor was Black Star going to deliver on their promise he did what he could to help Kim and Shego again.

Black Star launched its final attack, with the help of evil women from different dimensions. Their ultimate plan was to release a powerful witch named Ultimeca. It was then shown that this witch would not side with Blackfire. She had used the woman as nothing more than a pawn in her plans. In the end Team Go had discovered their true potential. But it was Blackfire who had ultimately defeated the witch. She defeated her by banishing her to Hell with the help of Ai.

Before the all powerful witch had been released heros from other dimensions had been summoned to aid Team Possible and Team Go. S.H.I.E.L.D, JLA, Avengers and other heroes had done what they could to stop Black Star. Now everyone was about to be done with the mess Black Star had created.

"Going to another world to hunt down and capture the last three members of Black Star. This should be fun" Shego said with a smirk as she looked to Kim.

"There's something you three should know" Katara said turning to face Kim, Shego, and Jacob.

"And that is what?" Kim asked looking at her.

"My world has been at war for a hundred years. Azula is the princess of the Fire Nation, the ones who started the war" she said looking around at them. Her blue eyes scanning them over as they traded glances.

"Look Katara, as much as we would love to try to stop the war we can't. We are going to apprehend Azula, Juri, and C. Viper" Kim said looking to the Water Tribe girl.

"Still, a war torn land hunting down three woman who kicked our asses. It would be a wise idea to gear up" Jacob said making both Shego and Kim look back to him. His arms were crossed and his head was down. His hair, black as Shego's and very shaggy hung in front of his eyes. The former soldier had his M-4 slung over his back. His brown eyes lifted up to them, both of them looking at them.

"Right, he has a good idea" Shego said with a nod.

"What and you fucking trust him? All this shit that happened was partly his fault" Kim said making Shego look at her.

"Princess he has proven he's on our side again" Shego said looking at Kim.

"Oh like how?" Kim challenged folding her arms across her chest as she looked at Shego.

"Kim, when Azula shot me with lightening it was him and his friends who brought me back" Shego said placing her hands on Kim's shoulders.

Kim looked at her, her olive eyes locked with Shego's green eyes. Slowly she looked over to Jacob, his eyes weren't even on them. Instead they were looking at a picture, one of him and Lex together. He placed the picture back into the pocket of his frayed jeans. He brushed his hair back before looking back over to them.

"Fine, I still don't fucking like it" Kim grumbled before the three walked away from the portal.

Jacob couldn't hold it against her, Kim was right he was just a traitor. He pulled the picture out again and looked at it. He had broken one rule that was unforgivable, he had turned on his family. He stuffed the picture away just as a green and black 1970s Dodge Charger pulled up and came to a stop in front of him. The door opened and out stepped Frank Castle a.k.a The Punisher. The vigilante had once been Jacob's drill sergeant.

"Hey Kid" Frank said, using Jacob's old call sign. "I got what you wanted."

Jacob looked as he sat a black duffle bag on the hood of the car. Opening the bag he reached in and pulled out a massive revolver. It was a .500 caliber Smith and Wesson. Jacob looked at it, his eyes trailed down to the handle. Gold initials had been inlaid into the handle. It said; LM & JM.

He holstered the revolver in his rib holster before looking to Frank. "Thanks Frank, got explosives, camera, enough ammo to win a small war. Also back up ammo for Kim and now a few spare weapons for Shego. Finally a couple of sets of clothes."

"Be careful Kid, oh take this" Frank said pulling his black duster off. He handed it to Jacob and looked at it as he took it. He looked to Frank who just nodded. "You've earned it."

Jacob put it on before he picked the duffle bag up. He looked down as the coat went all the way to his ankles. Looking back to Frank he extended his hand as to which The Punisher took it. "Thanks Frank" he said shaking his hand.

"I hope you find what you are looking for Kid" Frank said with a nod towards the portal making Jacob look at it.

"Me too" was all he said moving towards the portal to wait for Kim and Shego.

"I still don't fucking trust him" Kim mumbled as her and Shego walked over to Tiara.

"He's coming with us, he knows their weakness, and if we are being thrown into war we'll need him" Shego replied looking at Kim.

Kim huffed a bit still not happy that Jacob was coming. Deep inside she still believed that he and Shego had relations behind her back. Quickly looking up she saw the JLA jet come and land in front of them. The hatch opened and Wade came walking on out. He was carrying some things in his hands.

"I brought some things I whipped up for you two" he said looking at Shego and Kim.

"Oh boy presents" Shego chuckled looking at him.

"Yup, for you Kim I made a hybrid suit. It's a cross between your enhanced Black Star suit and your Battle Suit. If it's damaged the nano tech will repair it quickly. It's fire resistant and if your powers return it will accommodate them. The battle suit part of it will enhance your powers" Wade said passing her a suit.

Looking down at the suit it was black like the Black Star suit she had worn when Cortez had captured her. It had light blue lines going down it. She smiled before disappearing into the jet. In a few minuets she walked back out. Her swords on her back, sais on each hip. On both of her thighs were a pair of .50ae desert eagles. She had them holstered on each hip.

"Ooh Kimmie got another upgrade" Shego said walking over and giving her a quick kiss.

"And for you Shego a new suit, one similar to Kim's. Fire resistant, able to repair itself, and like hers if your powers return it will enhance them. I had managed to infuse bits of the comet that gave you your abilities into the suit" Wade said looking at her before passing her the other suit in his hands.

She looked down at the suit before looking the suit she had on over. It was torn, exposing her mid rift and cleavage. Her pale hand was out, the glove over her left hand had been torn off. She smiled before walking into the jet. She walked back out in a few minuets dressed in her new suit.

"You look hot" Kim said with a smile before walking over to her side.

"I do don't I" Shego said looking herself over.

"You two be careful, just come back" Tiara said hugging them both. They looked at her and smiled as Kim hugged Ron goodbye.

"You two ready?" Jacob asked walking up. They turned and looked at him. He looked different too, new guns, new outfit, and a new look in his eyes.

"Yeah, let's go" Shego said looking at him. "Even you got an updated outfit" she said nudging her shoulder into his. This action made him smile before they started walking towards the portal where Katara waited.

"Wait" he said making both Kim and Shego look at him. He turned and looked at Tiara who was looking at him. Four hours earlier she had professed her love for him. He had rejected her because of what he had done. He looked at her, her face blushing a bit as he walked over to her. As he walked he tugged out two necklaces, one was of his dog tags from when he served. On that chain was a diamond ring, it was the one he had proposed to Lex with. The second one was a mushroomed bullet, his lucky charm. He took it off of and placed it in her hand.

"What's this?" She asked looking at the necklace.

"It's my lucky charm, that bullet almost killed me. So when it was removed I requested to keep it and make a necklace out of it. I want you to have it, maybe the luck will go to you too" he said looking down at her.

She looked at the necklace before back up to him. She quickly threw his arms around his neck hugging him tightly. A lone tear slipped from her eye as she felt his left arm wrap around her. "Just come back to me" Tiara said before he let her go.

"I don't make promises if I can't keep them" he said softly before walking towards the portal.

"You three ready?" Katara asked looking at them.

"Yeah, ready as can be" Kim said looking at her.

Together the three walked forward. One by one they walked into the shimmering portal. Shego was the last one in. She was in awe at its splendor. It was a purple color, swirling around them. She felt weightless as she floated behind everyone.

"Go Team Go" she heard from her right making her look. She saw it in the wall of the portal. Her and her brothers when they had founded Team Go. She looked around to her left to see the day she had left the team for a life of crime. Looking around she was seeing flashes from different times in her life.

She saw the pyramid in South America where it had all started. She saw herself battling the hunter, the serpents, and finally the serpent queen. She reached up and rubbed her cheek, feeling the lightening bolt scar on her cheek.

Looking around she saw it go to the dinosaur infested island. The night they had been attacked before they were caught up fighting raptors. It then flashed to the first time she met Jacob. The man had saved her life. It then jumped to when her and Kim were in the tree for the night. Their kiss, one that wasn't real at the time. It then flashed to her fighting the mind controlled Kim. Another vision appeared, when Kim has Shego skewered to the ground when she broke the mind control.

It jumped to them riding on Jacob's boat, leaving the island behind. Their eyes were locked and they slowly leaned in and their lips met. It was their first real kiss. Shego smiled at the memory. Her hand went up and touched her lips, feeling Kim's on hers. Looking up she watched many others memories flash by. The first time they made love, their first real date, and the massive xeno attack

Kim's death flased by reminding her of the death that almost broke her. Looking away she closed her eyes banishing the memory away. "Never again" she mumbled softly telling herself she would never let that happen again.

Jacob watched his own memories flash by. He saw Lex just before he left for basic. He watched as he presented her the ring. She happily accepted it and kissed him. It flashed to her death reminding him of the most painful part of his life. He looked away and looked as the next memory was him saving Shego.

Jumping forward he saw after XeYori was defeated it was of the whole team in a pizza shop eating and laughing. He looked over to see the day he turned on Shego and Kim. He turned on them for an empty promise of returning his dead bride to be to him.

It flashed again showing his fights with Kim and Shego. He had chances to kill them, but he couldn't no matter what. He loved them, they were his family and he had turned on them. He looked down at his revolver thinking of just ending his shame now. He couldn't though, they needed him.

XX

Kim looked at her memories as they played out on the walls of the portal. She saw her first mission making her smile at it. Looking around she saw many of the same memories that Shego had except from her point of view. The kiss she gave her in the tree while she was under mind control from Cortez she had ment it.

It flashes to her fighting xenos in Middleton. She saw her own death at the hands of XeYori. She turned away from it and looked in the direction of some more memories. She saw her tapping into a new plasma power she had gained from when Shego had saved her life. She looked at her and Jacob fighting.

She snarled a bit remembering what he had said to her. He had admitted to sleeping with Shego. That had caused her to go into a fury. Every time she had a chance to kill him people had stopped her. She was going to make sure of something, he was not going to return to their world.

Suddenly there was a bright flash and she landed on hard stone. Looking forward she saw Katara standing in front of her. Looking back she looked as Shego and Jacob landed on the ground. Walking over to Shego she placed her arm around her waist. They looked as Jacob stepped forward, slinging the duffle bag over his back. He cocked the action of his M-4 and looked around.

The sun shined down on them as birds flew over. The buildings that surrounded them were almost Japanese in design. Looking behind themselves the portal closed revealing a large building. They looked at it, golden dragons were on the building. It had massive pillars holding the roof up. One thing seemed to bother all of them, no one seemed to be home. It was completely deserted making Kim, Shego, and Jacob trade worried glances.

"No, this isn't good" Katara said making them turn and look at her.

"What is it Katara?" Shego asked looking at her.

"This is the Fire Nation capital city" she said looking to the three of them. They looked at her, remembering what she had said earlier. They were in the capital of the nation that had started a war. Looking up the saw a figure fly by. Katara's eyes shot wide. "AANG" she screamed making the figure look down.

It swooped down and they looked at a twelve year old boy. His bald head had a blue tattoo of an arrow. He wore orange and yellow robes, similar to that of the monks on earth. His gray eyes looked at the three people who stood behind Katara.

"Who are you three?" Aang asked looking at them. "And were you the ones who kidnapped Katara?" He growled looking at them snapping his staff at them. A breeze shot by them making them trade looks.

"No, they didn't kidnap me Aang, they needed my help..." Katara was in the process of explaining what happened when three explosions went off. They all looked back as three water jets shot into the air. "It's begun, the invasion" Katara said looking at Kim, Shego, and Jacob.

"I'm going after Ozai, you need to get to Sokka and your father on the front line" Aang said spinning his staff making ten foot long wings shoot out of it, and taking off into the air.

"Did he just fly away?" Jacob asked pointing at the kid.

"Later, we need to help Katara" Shego said looking at him.

"Well it ain't the full Team Possible but it'll due" Jacob said walking forward with them.

Kim quickly turned and looked at Jacob. He stopped and looked at her. "Let me make this clear fucker, it is me and Shego. You are just here as the help. You are only here because you know Black Star. Make one false move, give me one good reason and I'll cut your fucking head off" Kim snarled taking her sword out and putting the tip to his throat.

"Kim we need him now, he's a soldier. We need to let it go right now. We need to help Katara get to where she needs to go" Shego said placing her hand on the hilt of the redhead's sword.

She looked at Kim who looked back at her before to Jacob. The sword lowered and she sheathed it. Kim turned her back to Jacob. Slowly the four walked up a small hill. Together they looked on as the invasion force started up the beach.

"Let's go" Kim ordered walking down the hill leading the way.


Well that closes out the prologue honest thoughts please. As promised this is the music mix I promised y'all. This is like the main soundtrack to this story. I had help from Raischenzo himself to make this mix. Since I had time to prepare I tweaked this mix big time. Once each chapter is over I will put up a tracklist to go with each chapter. There will be a main song on the chapters I deem. The main song will come from the soundtrack. Well give me your thoughts on the mix.
