Alright. Here we go. We're finally gonna see if the Avengers, Barry, and Oliver can stop Thanos and save the multiverse.

BTW, I decided not to give Oliver the power to fly. Despite getting many reviews saying it would be good, I eventually decided that I couldn't visualize it, and that there might be powers more suited to Oliver I could give him.

Let's get to it.

Chapter 13- Thanos comes to Earth

Oliver holds tightly to his bow as he flies through the air, holding tightly to Rhodey with the other hand.

Oliver looks back at the battlefield. The Battle of Wakanda is almost over. Thor has massacred the aliens on the battlefield, and is now chasing the last few back to their ships, destroying the ships in the process.

Oliver lands in the trees besides Barry. He sees a bit of blood on Barry's hand, and seeing Corvus Glaive's corpse, knows who was Barry's victim.

"You okay?" he asks.

"Yeah. I'll be fine. Using killing as a first resort is not something I want to make a habit of, but in this instance, it couldn't be helped," Barry responds.

"At least you get it now. Sometimes it's necessary," Oliver says.

"I still don't want to be known as a killer. But, if I can't see another way out of it, I'm okay with making that call now," Barry responds.

Oliver nods. Right then, Wanda flies in and lands beside Vision, kneeling down to check on him. Both Oliver and Barry look at her and Oliver asks, " So, how did you end up with her? What about Iris?"

"I got dropped on Earth-99 by the vortex 3 years ago. I saved Wanda's brother, though he ended up in a coma. We got to be friends, then started dating, then got married. I had to go back to Earth-1 to deal with some new villains right after our wedding. I only just came back to Earth-99," Barry responds.

"Well, I think it's about time I get introduced," Oliver says. Barry grins, and turns towards Wanda and Vision to get Wanda's attention, only for Vision to cry out in pain.

Both Barry and Oliver look at Vision, concerned. Wanda also worried, asks, "What? What is it?"

Vision looks up, and everybody close enough can see the fear in his eyes. He looks right at Wanda as he says, "He's here."

Oliver's face hardens, knowing who Vision is talking about. He quickly draws an arrow and fits it to his bow, looking around for any sign of Thanos.

A chill descends on the area, and the wind begins to pick up. By now, almost everybody has assembled at the site. Steve looks up at the trees and calls out over comms, "Everyone on my position. We have incoming."

Everyone looks around, waiting anxiously. It only takes a few moments before Banner turns around and sees a blue portal opening up behind him. The portal crackles and grows for a few moments before Thanos steps out, the Infinity Gauntlet on his left hand, with all but one of the Stones fitted to it.

Everyone's attention is drawn to Thanos. Assuming this is him, everyone who hasn't met the Mad Titan can instantly see why Banner was so shaken by Thanos. His very presence is intimidating, and he exudes an aura of power.

"Cap, that's him," Banner confirms his identity.

Steve expands his gauntlets into combat position and says, "Eyes up! Stay sharp!"

Banner lunges for Thanos, but using the Space Stone, Thanos turns him intangible and sends Banner falling through Thanos before solidifying halfway through the cliff.

Barry races at full speed towards Thanos, but with a wave of his hand, Thanos uses the Power Stone to knock Barry flying out of the way. He knocks Steve aside in a similar manner, then grabs T'Challa by the throat as the Wakandan leaps at him, then punches him in the face. Sam comes flying in, firing his pistols, but a burst from the Power Stone downs him.

Barry gets back to his feet, then starts racing around Thanos. Charging up enough energy, he sends a lightning bolt at Thanos, but to his shock, Thanos uses the Space Stone to turn the bolt around and send it back at its caster. Barry is knocked flying into a tree.

As Wanda watches this in horror, a hand grabs her wrist. She turns around to face Vision, who says, "Wanda. It's time. You need to destroy it."

"No! Vision, I can't kill you!" Wanda cries.

"Wanda, you have to. Only you can destroy the stone. And we are out of time. If Thanos gets the Stone, half the universe dies. I know you don't want to, but we can't let so many die. Please, Wanda. This is my choice," Vision pleads.

Wanda is torn, wanting nothing more than to refuse. But, deep down, she knows she can't. So, she slowly nods, raising her hands.

"Thank you for being my friend," Vision says. Wanda nods, a tear in her eye, and she says, "Thank you for being mine." And then, she unleashes her power on the Mind Stone.

As Wanda tries to destroy the Stone, the Avengers try desperately to slow him down. Rhodey unleashes every weapon he has, but they're all blocked by the Space Stone. Thanos then uses the same Stone to squeeze Rhodey's armor and throw him aside. Natasha and Okoye both race to the attack. Thanos sends Okoye flying, then uses the Reality Stone to rip rocks from the ground to trap Natasha.

Barry regains his feet and races at Thanos, firing his repulsors. The blasts do little besides annoy Thanos, as does a speed punch. Barry comes in for another punch, only for Thanos to block it with the Gauntlet, breaking Barry's hand. He then knocks Barry back before using the Reality Stone to bring up more rocks from the ground to trap Barry.

By now, only Groot, Morris, and Oliver remain between Thanos and the Stone. Groot unleashes a torrent of vines, but Thanos rips them apart and uses the Power Stone to knock Groot flying.

Morris turns his body to water and sends a jet of water streaming at Thanos, firing at a pressure several times greater than a firehose. Thanos blocks it with the Space Stone, though the pure force of the jet forces him back a few feet. Thanos then uses the Reality Stone to force Morris to return to solid form. Using the Space Stone, he pulls Morris towards him before punching him in the face, knocking him out.

At this point, Steve has recovered and runs towards Thanos. Thanos takes a swing at him, but Steve ducks under the blow. Using his gauntlets, he then lands several blows. Thanos, impatient with this, tries to knock Steve down using the gauntlet. However, Steve holds out his hands and grabs the Gauntlet, stopping it a few inches from his face. Thanos is genuinely surprised at Steve's strength. However, with Steve holding the Gauntlet with both hands, he can't defend against a punch from Thanos' free hand. With a powerful blow from his right fist, Thanos knocks Steve to the ground again.

Thanos looks up and sees Oliver is the only one standing between him and Wanda. "You're not getting past me," Oliver says before firing an arrow into the ground at Thanos' feet.

Thanos looks down at the arrow, then back at Oliver. "You missed," Thanos says.

Oliver smirks. "No, I didn't," he responds. Right then, the arrow discharges a massive burst of lightning. The lightning actually forces Thanos back a step and dazes him for a moment.

Taking this brief advantage, Oliver leaps at Thanos, smacking him in the head with his bow. He then draws another arrow and fires it into Thanos' chest. Thanos is surprised when the arrow penetrates his skin, hurting more than Tony's attack on Titan that drew his blood.

Oliver manages to land a few more blows before Thanos recovers himself. Thanos grabs Oliver's bow with the Gauntlet and rips it from his hand. Using the bow, he then strikes Oliver multiple times. His new armor protects him from the blunt of the blows. But, it doesn't protect his face. His nose breaks from a particularly hard blow. As Oliver staggers back, Thanos pulls the arrow from his chest and slashes it at Oliver, opening a cut on his cheek.

Oliver falls to his knees as Thanos throws the bow and the arrow aside. Looking up at Thanos, he realizes that this is what he saw in that dream on the Commodore during the journey from Sakaar to Asgard. Him, kneeling on the ground before Thanos, bloody and beaten. He has just enough time to reflect on this before Thanos punches him in the face, knocking him down.

Thanos looks down at Oliver for a brief moment before looking back up at Wanda and Vision. But, Oliver had done what he intended. He had bought Wanda enough time. Just as Thanos looks up, the Mind Stone finally succumbs to Wanda's power and blows apart, blowing Vision apart with it.

Thanos covers his face for a moment before looking back at the scene before him. Vision is gone, with just scattered pieces of him left. Wanda lies on the ground where the blast knocked her, crying in grief over her friend.

"I understand, my child. Better than anyone," Thanos says in a low voice.

Wanda, tears on her cheeks and fury in her eyes, looks up at Thanos and says in a venomous tone, "You could never."

Thanos looks up before responding, "Today I lost more than you can know. But now is no time to mourn. Now is now time at all." He then steps forward before activating the Time Stone. A circle of green energy forms in front of his palm, which he begins to turn. And slowly but surely, time begins to turn back.

Realizing something is happening, Wanda looks up and sees as the fragments of Vision slowly begin to gather again until, finally, they completely reassemble, revealing both Vision and the Mind Stone intact once more.

"No!" Wanda screams. She tries to scramble back to her feet, but Thanos swipes his fist at her, sending her flying.

Slowly, Thanos grabs Vision by the throat and lifts him up. Then, he slowly reaches out, takes hold of the Mind Stone, and rips it from Vision's head. Instantly, Vision's body goes limp, and the color drains from it, leaving Vision's body completely gray.

Thanos tosses Vision's body aside, where it lies motionless. Thanos' eyes are fixed on the Stone in his hand. He raises the Infinity Gauntlet and slowly moves the Stone into position. As he feels the Stone pulling against his fingers, he releases it, and the Stone flies into place.

Thanos yells out as he feels the power surge through him. As the surge fades he looks down at the Gauntlet. It's finally complete. All six Stones are his.

Suddenly, he's cut off as a powerful lightning bolt hits him and knocks him skidding back into a boulder. The bolt is from Thor, who is descending on Thanos from the sky. Thanos leaps back to his feet and fires a beam of energy from the Gauntlet at Thor. However, Thor pours all his strength into Stormbreaker and throws it at Thanos. The beam and Stormbreaker collide, and the axe cuts right through it, all the way to Thanos' chest.

Thanos collapses to one knee as Stormbreaker enters his chest. Thor lands in front of the Mad Titan and slowly walks up to him. He places his hand on the back of Stormbreaker's head and looks into Thanos' eyes. "I told you...you'd die for that," Thor says furiously, referencing the death of Heimdall. And with that, he pushes Stormbreaker deeper into Thanos' chest.

Thanos' eyes bug as he bellows in pain. Thor looks right at Thanos with dark satisfaction at the pain he's feeling.

Thanos gasps as he feels himself weakening. Then, he looks up at Thor and manages to get out, "You should….you should've….you should have gone for the head."

Out of the corner of his eyes, Thor sees Thanos raise the gauntlet. From across the clearing, Barry has managed to free himself. He looks over and sees Thanos raising the Gauntlet. He and Thor's eyes widen, and they both cry, "NO!" as Barry prepares to run at Thanos in a last desperate attempt to stop him. But it's too late, and Thanos snaps his fingers.

There is a sound like a thunderclap, and bright flash of light. When the light fades, Barry and Thor can both see that the Gauntlet is damaged. It looks like someone threw it in a wood chipper then took a blowtorch to it.

"What did you do? What did you do?!" Thor bellows at Thanos. Thanos doesn't respond. Instead, he raises his fist and activates the Space Stone. He almost falls back through the portal before it closes, leaving Stormbreaker behind, the blood on the head the only sign that Thanos was there.

By now, most of the Avengers have regained their feet. Steve, nursing a bruise on his arm, looks at Tor and asks, "Where'd he go?" When Thor doesn't respond, he again asks, "Thor, where'd he go?"

"Flash?" Steve, Thor and Barry look at Morris, who is looking down at his hands, which are disintegrating into dust. He looks up just as the rest of him disintegrates. The three men watching stare in horror.

A few yards away, T'Challa scrambles towards Okoye. "Up, general. Up! This is no place to die," he says, reaching out to pull her to her feet. She reaches out to take his hand, but it disintegrates as she does, followed by the rest of T'Challa. She looks on horror at the sight.

As this is happening, Groot is beginning to disintegrate. "I am Groot," he says weakly.

Rocket watches painfully as his friend is disintegrating before his eyes. "No. No, Groot, no," he almost moans mournfully as Groot disintegrates.

A few yards away, Sam is trying to regain his feet, but is never able to as he disintegrates. Nearby, Rhodey calls out his name, not knowing that he no longer exists.

Barry is looking around in horror at what is happening. Then, he hears Wanda call, "Barry."

Barry looks over at Wanda, and his eyes widen in horror at the sight of his wife's hands disintegrating.

"NO!" Barry screams before racing over and dropping to the ground in front of her.

Wanda looks up at him, tears in her eyes. "I love you, Barry. Take care of Nora and Stephen, and tell them Mommy loves them," she says tearfully.

"No, Wanda, no!" Barry cries, but is forced to watch as his wife disappears before his eyes.

Barry just sits there as the dust floats away in the wind. He tries telling himself this is all a bad dream, but in his heart he knows it isn't. Wanda is gone. His wife is dead.

Thanos has won.

And, I'll end there.

I know some of you were probably are disappointed I ended up having Thanos succeed. But, let's be honest. The Avengers are not united, and not fully prepared to deal with Thanos. And they haven't had enough time to truly prepare for a threat of the magnitude of Thanos. Also, just to confirm, this story will be ending in two chapters, and I will be covering Endgame in a different story. That story will be fairly different than Endgame, and may or may not do the time heist, but I'm not positive yet.

Now, I know a lot of people were hoping Wanda would survive and that the Allen family would stay together for the next story. But, for my plans for the future she had to die in the Decimation. I'm sorry. The main reason will be explained in the last chapter of this story. But, obviously, she won't be gone forever. So, as some people have mentioned, don't give up on this story. Events triggered by Wanda's death will open up a whole new realm for the MACU.

I hope you don't mind that I seriously powered up Oliver. But, with an uru bow and arrows, he would be. And since I wrote that chapter in Arrow: Ragnarok where he had the dream about kneeling on the ground in front of Thanos, I knew I wanted to do it like this. Plus, I liked the idea of Oliver being the last line of defence. Plus, it'll be kinda nice when he's with Barry and Kara now that he's not completely without super powers. Also, it's been confirmed that those who wield Mjolnir can have their strength and fighting skill augmented by the hammer, as we saw when Steve used it to take on Thanos alone. So, since Oliver's new bow is also made of Uru, I figured it could have similar powers and enable Oliver to hold his own against Thanos for at least a little bit.

Next chapter will show the aftermath of the Snap, and we'll see more how Barry reacts to his wife getting turned to dust. Until then, please review and tell me how you think I did with this, and stay tuned!
