Hello everyone ! That's it ! You've been waiting for it for a long time, I finally started the continuation of my story crossover Arrowverse Avengers in the history of Endgame. This is the chapter 1. I hope you enjoy it.

Good reading.

Chapter 1

A time ago... my name was Kara Zor-El,

I'm from Krypton. I was a refugee on this planet. I was sent to Earth to protect my cousin. But my pod got knocked off-course, and by the time I got here, my cousin had already grown up and become... Superman.

I hid who I really was until one day when an accident forced me to reveal myself to the world. To most people, I was a reporter at CatCo Worldwide Media. But in secret, I worked with my adoptive sister for the D.E.O. to protect this planet I call my home from anyone that means to cause it harm. I was… Supergirl. At least I was.

Everything changed when Thanos landed and wiped out half of the universe with the power of the six Infinity Stones. And that I saw all my friends and family gone in ashes. We had lost. We had all lost.

Song: Dear Mr Fantasy of Traffic.

Somewhere in space

The Benatar, the ancient ship of the Guardians of the Galaxy, was sailing in space thousands of light-years from Earth. The only occupants on board were Tony Stark aka Iron Man, Oliver Queen aka Green Arrow and Nebula, a former child of Thanos who rebelled against him. All the others were gone in ashes.

On board the ship, Oliver was doing his best to stay optimistic. His mind kept thinking about how everyone had disintegrated before him on Titan. He thought of his whole team on Earth, Felicity and William. Had they survived? Had they gone to ashes too? Oh, he didn't even want to think about it.

During the first days in space, he had devoted himself to making a new bow and arrows, from objects he had recovered from Titan. While building his new weapon, he became acquainted with the pragmatic nature of Nebula. She had told him about her past, the years she had spent serving Thanos before rebelling. For Oliver, it was obvious that she views Thanos in the same way that her little sister Thea views Malcolm Merlyn. Talking with her, while making his bow, allowed him to think of something other than his family and friends. Nebula had even taken care of Tony's wound.

The more days passed, the more the chances of reaching the Earth dwindled. During the battle on Titan, the fuel cells cracked, but Tony and Nebula had found a way to reverse the ionic charge and get forty-eight hours more. But now they have stalled. Their food supply was exhausted. Oliver and Tony were starting to suffer from malnutrition. And the Earth was still out of their reach. To believe that they were going to die in space.

Several times to pass the time, Tony and Nebula played football on paper. Tony had suggested to the archer to join him, but the latter had refused, preferring to focus on his bow and arrows.

Finally, Oliver had once again settled on one of the cabin seats and watched the stars from the porthole. It was a magnificent sight, he had to admit it. He couldn't believe he was going to finish like this. From Liam Yu Island so far. If only he could hear from his relatives on Earth. If they were all in ashes, Oliver preferred to die of malnutrition rather than face the world without his family.

He watched Tony Stark send a farewell message to his beloved Pepper Potts, then fainted. With Nebula's help, he had installed it on a cockpit seat. The archer had resumed his place and waited. He waited for the moment when he felt his strength leave him. He imagined he saw Felicity and his son with him.

As he waited for death, a bright light dazzled his eyes. What was happening ? Was it heaven? No, he was sure he was still alive, despite his weak state. Oliver was doing everything to try to distinguish this brilliant light that dazzled him and managed to see… a woman?

A woman in space? Was it Kara? No, she doesn't look like Kara. A woman floating in space? But who is she?

The blonde woman who was floating in the space watched the occupants of the cockpit, then disappeared. Shortly after, Oliver felt the ship move. What was happening ? Was it an angel of space who came to their help?

Earth of Avengers

It had been more than three weeks since the battle in Wakanda. Since Thanos had snapped his fingers, and half of the universe had disappeared. It was total chaos all over the Earth.

In the sullen Avengers' compound, Kara watched the missing people on a holographic screen. The kryptonian was enormously affected by the powerful defeat they had just suffered. She had seen her friends Barry and J'onn disappear, then her sister Alex, then others who had gone to had the sensation of reliving the drama of Krypton. She remembered how she felt when her world was destroyed. Grief, despair, mourning… Today, she lived almost the same tragedy and she did not know if she would be able to overcome it.

In the days that followed, Kara gave up her superhero suit, wore simple clothes and did everything to help the surviving Avengers locate Thanos, with no results. During her research, she had met Carol Danvers, aka Captain Marvel. A woman with incredible powers. She would be the equivalent of a Supergirl on this parallel universe. Kara had met her after a man had tried to contact her on an old beeper. She had answered present and hastened to help them.

The Kryptonian didn't return to her Earth from Wakanda. Not even once. She knew that her world had been ravaged by the mad Titan's hand-snapping, and wasn't ready to face chaos in her own city. She didn't want to know if her other friends were still alive. John Diggle, on the other hand, had returned to Earth – 1, then returned some time later. Kara hadn't dared to ask him how he was doing. Seeing his helpless look, she concluded that his Earth was in the same chaos as the Avengers'.

As she watched the missing people on the holographic screen, the whole building began to shake slightly, then severely. According to her super-hearing, it was a spaceship.

She went out into the outer courtyard of the compound, and stared at the starry sky. She was joined by Steve Rogers (who had just shaved his beard), Bruce Banner, Natasha Romanoff, James Rhodes and Pepper Potts. Then came John Diggle, near the kryptonian.

All saw the great ship, supported by Captain Marvel to land softly in the yard. The landing gear unfolded as they touched the ground. The front door opened, then Kara saw Tony and Oliver, supported by a bluish humanoid. Steve ran to help Tony, while Kara and Diggle ran to help Oliver.

"I couldn't stop him," whispered Tony to Steve.

"Neither could I."

Oliver, in a weakened state, seemed relieved to finally see familiar faces.

"Kara… John…"

"Oliver," said Kryptonian, taking his friend in his arms.

"I'm glad to see you again, Oliver," Diggle exclaimed, looking shaken.

"Thanos... won..." the archer mumbled, looking away as he pulled away from his friend's embrace.

"Yes, we all lost!" Kara replied.

Oliver was surprised to see only Kara and John taking care of him.

"Where are the others ? Why are you alone?"

Kara and Diggle exchanged sad looks. Oliver watched them both, and realized that his fears he had had in recent weeks were well founded. After a silence, John Diggle looked at his friend, answering sullenly:

"It's just us, Oliver! Renee, Curtis, Dinah ... they've gone to ashes..."

The archer of Earth – 1 received a hollow in the stomach at this revelation, then looked at John with a frightened air.

"Felicity?"

Diggle shook his head in response. Oliver felt his tears fall.

"And William? My son ? Is he okay?"

Diggle shook his head before answering:

"I went back to our Earth after ... what happened ... Star City is completely annihilated. A lot of people have gone to ashes, like here ... Lyla and my son have disappeared ... I did not find William ... I think ... he disappeared, too."

Thus, his fears came true. Oliver had lost his family. He no longer had a team, and no family. Completely distressed, the archer collapsed to the ground, tears in his eyes. Kara, sad face knelt beside him.

"I lost my sister! I'm so sorry, Oliver!"

Later, everyone was gathered in the living room. The holographic screen showed the faces of people who had disappeared into dust. Oliver and Tony were sitting at a table, hooked up on a drip to were sullen.

After having all met, James Rhodes made an update on the situation:

"It's been twenty-three days since Thanos came to Earth."

"World governments are in pieces," Natasha continued. "The parts that are still working are trying to take a census. And it looks like he did... he did exactly what he said he was gonna do. Thanos wiped out fifty percent, of all living creatures."

While listening, Oliver saw Peter Parker's holographic face, and once again had a hollow in his stomach. Peter Parker, aka Spider-Man, this young man who had fought alongside him against Thanos on had witnessed his disappearance.

"Where is he now?" Tony asked.

"We don't know," Steve said. "He ... He just opened a portal, and walked through."

Tony looked at everyone and noticed Thor in a corner, ruminating, looking sullen.

"What's wrong with him?"

"Yeah, he's pissed," said Rocket, who had grown small so far."He thinks he failed. Which of course he did, but there's a lot of that's goin' around, ain't there?"

Oliver and Tony then noticed the raccoon talking and looked stunned.

"Honestly, until this exact second, I thought you were a Build-A-Bear." exclaimed Tony.

"Maybe I am," said the raccoon.

Oliver, staring at Rocket, whispered to John in a low voice:

"Is that a…"

"Yes Oliver, it's one, but don't say it out loud. He's very sensible."

First a Cloak, now a talking raccoon! What a strange universe!

"We've been hunting Thanos for three weeks now." Steve explained. "Deep Space scans, satellites, and we got nothing. Tony, Mr. Queen, you fought him."

"Fought?" exclaimed Oliver shocked. "That's an understatement."

"Who told you that?" Tony added."We didn't fought him. No, he wiped my face with a planet while the Bleecker Street Magician gave away the store. That's what happened. There was no fight."

"He had only five Stones when he was in front us," said the Earth archer darkly. "We had no chance of winning against him. As Tony said, there was no fight!"

"Did he give you any clues, any coordinates?"Steve asked.

Oliver remained neutral before retorting:

"He just said he was planning to rest after that. Rest and watch the sun rise on a grateful universe."

"Grateful?"exclaimed Kara, beside herself. "He's crazy!"

"I saw this coming a few years back," said Tony. "I had a vision. I didn't wanna believe it. Thought I was dreaming."

"Tony, I'm gonna need you to focus," Steve insisted, getting up to his friend.

"And I needed you," Tony said, looking at Steve Rogers with a glare. "As in past tense. That trumps what you need. It's too late buddy. Sorry. You know what I need? I need to shave. And I believe I remember telling you, Cap."

He began to get up and move everything that came to hand, and continued with his sullen air, withdrawing his perfusion:

"Otherwise what we needed was a suit of armor around the world! Remember that? Whether it impacted our precious freedom or not- that'swhat we needed!"

"Well, that didn't work out, did it?" Steve Rogers said simply.

"And it's not that easy," Kara added hoarsely.

"I said "we'll lose"," Tony said. "You said, "You said, "We'll do that together too." And guess what, Cap? We lost. You weren't there."

Steve didn't know what to say because he knew Stark was right. Rhodey was trying to put it back nicely, but Iron Man ignored him completely.

"But that's what we do, right?" continued Tony again. "Our best work after the fact? We're the Avengers, we're the Avengers. Not the Prevengers, right? Me, all I had besides the magician, it was Legolas of Earth Unknown! You Cap, who were you by your side, except your friends? You had Miss Goldilocks and Red Blur!"

"The Flash,"corrected Kara, in a harsh voice."His name was The Flash."

"Barry?" exclaimed Oliver.

In his grief, he didn't notice the absence of his speedster friend Barry Allen aka Flash.

"Where's Barry?" he asked.

Kara showed him the red speedster mask of Earth – 1.

"That's all that's left of him," Kara replied.

Oliver was shocked again and upset. As Tony continued his speech to Captain America:

"She's great by the way," (he pointed at Captain Marvel.) "We need you, you're new blood. Bunch of tired old mills! I got nothing for you, Cap! I got no coordinates, no clues, no plan, no options. Zero. Zip. Nada. No trust. Liar."

Then Tony snatched his Arc Reactor from his chest and shoved it into Steve's hand.

"Here, take this. You find him, and you put that on… You hide…"

Tony fell to the ground, everyone gathered around him.

"Tony!"

"I'm fine…"

And he fainted on the ground.

Later, Tony was lying in a bed in the infirmary, Pepper Potts was at his bedside. Rhodey came to see Steve, Natasha, Kara, Oliver and Carol Danvers to inform him of his condition.

"How is he ?"Oliver asked.

"Bruce gave him a sedative, he's gonna be out for the rest of the day," said the friend of Iron Man.

"You guys take care of him. And I'll bring Xorrian Elixir when I come back," Carol said, moving away from the group.

"Where are you going ?"Steve asked.

"To kill Thanos," she said as she left the infirmary.

Everyone looked at each other stunned.

"Is she serious ?" Oliver asked Kara, stunned.

The Kryptonian just shrugged.

Then, they decided to catch her.

"Hey," Natasha said. "You know, we usually work as a team around here, and between you and I, we're also a little fragile."

"We realize out there is more of your territory, but this is our fight too," Steve added.

"Do you even know where he is?"Rhodey asked.

"I know people who might," Carol said simply.

Then Oliver got in her way.

"Excuse me, but if you are looking for Thanos, I think I know someone who can lead us to him. Her. (He pointed to Nebula who was a few feet away from them.)

"Who's she ? And how does she know Thanos?" Kara asked.

"Her name is Nebula, she was one of his children. She knows him, she knows where he is."

Then the bluish alien joined them.

"Yes, I can tell you where Thanos is," she replied.

"Tell us everything you know," asked the archer of Earth – 1.

Nebula told her story to all the heroes gathered around the living room table.

"Thanos spent a long time trying to perfect me. Then when he worked, he talked about his great plan. Even disassembled, I wanted to please him. I'd ask "where would we go once his plan was complete?". His answer was always the same: To the Garden."

"That's cute, Thanos has a retirement plan," sarcastic Rhodey snapped.

"What's that, the garden?" Oliver asked, curious.

"A planet," said Thanos's child.

"A planet called the garden, seriously?" Kara said, stunned.

"So where is he then?" Steve asked.

Rocket, who was standing on the table, showed a representation of the Earth hologram.

"When Thanos snapped his fingers," he explained. "Earth became ground zero for a power surge of ridiculously cosmic proportions. No one's ever seen anything like it... Until two days ago… (the hologram showed a new planet) On this planet."

"Thanos is here," Nebula replied.

"Now we know where he is," Oliver said, looking at the hologram.

"He used the Stones again," Natasha exclaimed, looking at the holographic planet.

"But why?"Kara interjected. "He used Stones to destroy half of the universe, why use it again?"

"It doesn't matter, we now know where he is, and we have a spaceship to get us there," Oliver said, taking his new bow.

Bruce Banner intervened in his turn, not very enthusiastic about going to find the Mad Titan:

"Hey, Hey, we'd be going in short-handed, you know."

"Yes, because he killed all our friends and families," Diggle answered grimly. "I think we all know that here."

James Rhodes added:

"Look, he's still got the stones, so..."

"So let's get him," Carol suggested. "We'll use them to bring everyone back."

"Just like that?" asked Bruce.

"Yeah, just like that," Steve Rogers nodded.

"Even if there's a small chance that we can undo this," Natasha added."I mean we owe it to everyone who's not in this room to try."

"If we do this, how do we know it's gonna end any differently than it did before?" continued Banner still not convinced.

"Because before, you didn't have me," Carol said confidently.

Everyone looked at her, then Rhodey gave her an ironic look:

"Hey, new girl, everyone here is about that superhero life. And if you don't mind my asking, where the hell have you been all this time?"

"There are a lot of other planets in the universe. And unfortunately, they didn't have you guys," Captain Marvel explained.

Oliver, sure of himself, walked over to Carol.

"Would you know how to fly a spaceship?"he asked.

"I was a pilot of the United States Air Force, I know how to fly everything," she said, still smiling.

Then Rocket joined him.

"Hey, homie, I remind you that the ship that brought you here, your friend and you, it's mine. So, I know how to fly it."

"Fine," Oliver said, not used to talking to a raccoon with speech.

I talk with a raccoon! You have got to be kidding me!

"Oliver, are you sure you want to go?" Diggle intervened. "You stayed three weeks in space, and you have not recovered yet. You should rest."

"I'll go get some rest when we get rid of this monster and bring everyone back," Oliver said.

The Thor God, who ate a snack a little further, got up and walked quietly to Carol. He looked at her, while invoking his weapon the Stormbreaker who passed a few inches from the hair of the young didn't flinch and smiled quietly at the Asgardian.

"I like this one," he said smiling.

"Let's go get this son of a bitch!" Steve Rogers said looking at everyone.

"Yeah, Cap!"Kara replied as she opened her shirt revealing her Supergirl outfit under her clothes.
