Earth-1
Year: November 2016

The heroes who are known as Supergirl, but in her civilian identity as Kara Danvers, and The Flash, who in his civilian identity is Barry Allen, is currently racing across the world as they have been placing the small nano-weapons on the Dominators. It's a high-frequency transmitting device made by Martin Stein specifically used for the Dominators.

The Dominators are a race of extraterrestrial beings from Swan Moon. They are conquerors intent on maintaining the status quo in the universe by any means, with the unpredictable meta-humans being their prime targets on Earth.

With the appearance of meta-humans, especially Barry Allen who caused Flashpoint, the Dominators returned to Earth, prefaced with a warning to Earthly authorities that they meant no harm, though in fact planning war. Four ships crash-landed, one of them in Central City, spilling forth with Dominators.

This faction kidnapped the President and set up a mind control device in an old salt mine, but this device was eventually destroyed by Supergirl, with the help of The Flash. However, they soon abducted Sara Lance who goes by White Canary, John Diggle who is known as Spartan, Thea Queen who calls herself Speedy, Ray Palmer who likes to be known as Atom, and Oliver Queen who is now going by the Green Arrow, placing them into an induced dream world. They eventually escaped, fighting against the Dominators, before escaping in a pod.

As they headed down towards Earth, the mothership followed them. At this time, the Dominators were about finished with their superweapon that they intended to use to wipe out all metahumans on Earth. They threatened to drop it unless Barry Allen surrendered himself in 24 hours, which he refused.

They lowered the mothership down on Central City and began to drop the meta bomb, while a platoon of Dominators fought the heroes on top of the S.T.A.R. Labs hangar. And that's where the heroes are right now as the World's FInest being to circle across the globe putting the device on as many Dominators as they can.

S.T.A.R. Labs Hall Hangar

In the S.T.A.R. Labs hall hangar, Felicity Smoak, who goes by Overwatch, is looking over at the large computer monitor as it shows the location of all of the Dominators present with their massive ships. She is currently holding the detonator as she is waiting for the signal to activate it.

"All right, devices are being planted," Overwatch informs her teammates. "Let me know when I can bring the pain."

Up in the air the Waverider, a time travel ship, is currently in the air as it struggles to hold the meta-bomb that the Dominators planned to use.

White Canary is currently the one driving the ship as behind her the ship begins to spark. "Come one, Firestorm."

Outside of the ship, the transmuted hero Jefferson Jackson and Martin Stein, when fused together they go by Firestorm, are currently struggling to get rid of the meta-bomb. As Firestorm's powers are matter transmutation, they struggle to do it as it's bigger than they have ever done before.

"Grey, I can't do it, man," Jefferson tells his friend who is currently is in his head when they transform. "It's too big."

Meanwhile, on the roof of the S.T.A.R. Labs Hall, the other heroes known as Steel, Spartan, Green Arrow, Atom, Vixen, and Heat Wave were still engaging the extraterrestrial opponents. Defending their world from them.

"Still waiting on that signal!" Gren Arrow heard Felicity's voice over the comms.

Green Arrow turns around as he seems more and more Dominators by the minute. If they don't act soon, they'll all lose the battle and the Earth along with it.

"Do it!" Green Arrow ordered.

Immediately after that, Felicity, inside the hangar, activated the nano-weapons as she pressed the red button on the main device.

"Done," Overwatch said.

As soon as Overwatch pressed the button, almost all of the Dominators who had a nano-weapon on them begin to screech in agony as they fall to the ground. Unable to move but just scream in absolute pain as the heroes watch it.

"It's working," Green Arrow noted.

"What about the superhero bomb?" Heat Wave wondered.

Back up in the air, Firestorm is still not able to matter transmutate it.

"I can't! I can't do it!" Firestorm said to them as he can't transmute something this big.

"You must, Jefferson," Grey said in his head. "I have a daughter. Her name is Lily, and she's counting on you. She's counting on both of us."

Hearing this inspires Firestorm to try again as with that he begins to grunt as with all his might begins to finally matter transmutate the meta-bomb. All around the bomb, it begins to glow orange, before it finally transforms into water as gravity took it to the ground.

In the Waverider, Sara and Cisco Ramon, who is Vibe, look at the screen in shock and excitement as their friend finally did it and got rid of the bomb that would destroy the metahumans of the world. They almost think they wouldn't do it, but they did.

"They did it!." Cisco said with excitement as his hands are in the air while Sara sighs in relief. "They could do that?"

Sara looks back at Ciscos as she is still sighing in relief. "They did that. Ground, what's your status?"

On the ground, the Dominators got up and started running off, disappearing in yellow beams of light as they were transported back to their ship. All the while each and one of them screech and howl. The heroes stared at them with a mix of surprise, disbelief, and wariness.

"They're retreating," Steel noted, as his skin transformed to normal.

"It's not just them," Felicity said over the comms as she saw that all the Dominators are fleeing across the world. "It's all around the world."

Everyone begins to see that almost all of the Dominators are in their ships as they begin to fly and take off, away from the planet Earth knowing they can never defeat the heroes.

"He did it," Green Arrow said about Firestorm, as everyone came back as they stood on the rooftop relieved that the threat was over.

"No Oliver," Supergirl said next to him as Flash just races behind them.

"We all did it," Flash said as Green Arrow gave a small smile to his friend while Supergirl did the same.

Suddenly, there was a familiar screeching. Everyone turned to see a lone Dominator slowly walking towards them, despite its agony. It started right at them, holding on despite being in pain.

Green Arrow quickly drew an arrow and aimed it at the Dominator. "Don't move!" He bellowed at the alien.

The alien hissed loudly several times before he finally spoke in their heads. "You may have beaten us. Forced us to retreat. But, that does not change anything. You and your kind are still a threat. And we may not have achieved victory. But we can still have a small win."

With that, the Dominator pulled a small sphere and tossed it towards them. A beam then shot down from the sky and took him up to his ship, right before the sphere exploded, sending out a small shockwave, and opening a vortex in front of them.

The vortex begins to spin, and a fierce wind starts pulling at them, trying to suck them into the vortex. With no warning, Green Arrow was pulled off his feet and into the vortex, disappearing from view.

"Everyone move!" The Flash yells to his friends.

They all begin to retreat as Atom took Spartan and Heat Wave, with Firestorm taking Vixen and Nate into the air and away from the vortex. Unfortunately, Flash and Supergirl were left behind since they along with Oliver were close to the vortex. The World's finest are trying to outrun and fly it as they don't want to be sucked in wherever it will take them.

But as they do so, it was no use as they were pulled into the vortex as gravity took them there. All they saw as they were pulled in were blue space as they try to look around to see a void of nothingness as they are pushed into an upcoming portal.

Earth-939
Year: May 2012

They fall down the portal, their ears were filled with roaring sounds as it sounded like someone activated a flash grenade. They'll be alright, but has no idea where they are. The two look at each other for a moment as they try to stand up after being disorientated.

"You alright?" Flash asks Supergirl who was trying to make sure her ears were still working as all she hears is ringing. But after a few moments, she can hear again but figured out what Barry was saying.

"Yeah...yeah, I'll be fine," Supergirl answered as she then looks to where they are. "Where are we?"

The Flash too look around and see that they were on a road, with many buildings beside them. What caught their attention was the destruction that is around them as they hear blast noises from the sky.

"I think we are in New York" Flash theorized as he points to a new york taxi cab that was blown in two, but can still tell it's from New York.

"If we're in New York, then what is happening? And where is Oliver?" Supergirl asks as she is worried for her new friend.

"I don't know, but we gotta figure out what's happening first," Flash said to the Kryptonian. "Oliver can handle himself just fine."

With that the two races off, one in the ground and the other in the air as they zipped through the city to see what's going on. They begin to pick up speed, and before they know it, they made it the actual battle that's happening in New York.

Destruction is filled in Manhattan, as several new alien species, they have never seen before are coming out of a large blue portal in the sky. They stared in almost amazement seeing this, but it immediately changed where they saw the aliens coming down to Earth and causing destruction wherever it goes.

But that's not the most interesting part, what is, is a man in a suit of armor. It was colored in red and gold, with a blue glow in the eye socket, along with a blue glow on the chest, which powered up the entire suit.

The armored suit guy was chasing a group of those aliens as a big Quinjet type ship came in and started blasting the ones that chased their allies. Needles to say, the Kryptonian and speedster were surprised once more as they now have another problem to deal with.

"I think we have a new problem," Flash said, almost in a groaning tone.

"Yeah, let's see if they can use some help," Supergirl said to her friend, who nodded in agreement as they begin to take off again to help this world's heroes as they are going into another invasion.

And how was that? Did you all enjoy this chapter? I know it's a little short, but I thought it would be a good spot here. So, I would like to say that this story was formed thanks to Stand with Ward and Queen and Raptor2216 as they inspired me to make my own Barry x Wanda series. And yes, this is a Barry x Wanda story, so take a guess who the rest will end up with.

So because of their awesome series, I decide to make it but as I wanted it to be different from theirs, as that's why the Trinity is coming to the MCU in 2012 instead of the end of Age Of Ultron. I also would like to say, that this series is called the AMCU which stands for Arroverse Marvel Cinematic Universe.

If you don't know, the setting of this story in 2012 Avengers is that they just arrived to see Tony being chased by the Chitauri as Clint gave a hand. Don't worry, Oliver is okay too, as you will see him in the next chapter. This is also a test to see if everyone wants me to continue it or not. Be on the lookout for the rest of my other stories which you should all check out.
