Thank you to everyone who has favorited, followed or reviewed this story so far.

So finally, we reach the Invasion crossover. This is a bit of a challenge to write. But a challenge I enjoy. I'm totally free for a month which is why the updates are so fast. Late July, the updates will slow down a bit.

To Chaos Sorcerer: Thanks for pointing out the fault in the previous chapter. I edited it. I also prefer Marvel a little over DC but I love both. I also like the Avengers more. The reason the Avengers have better teamwork and better chemistry than Justice League in my opinion is that Justice League mostly have a working relationship while the Avengers are friends and hang out with each other outside of crime-fighting. But I can be wrong. The CW Arrowverse 'Justice League' is a different matter entirely.

Warning- Some bad language

Chapter 9- Aliens and Introductions

Daredevil, Green Arrow and Spartan entered the warehouse. Daredevil detected a presence and knew their opponent was there. Vigilante jumped down and brandished a pistol. Green Arrow fired an arrow that hit the pistol, making him drop it.

He brandished another big gun and fired at them. The three were about to dodge the shots. Daredevil then heard some rapid footsteps and a rapid heartbeat. He had never heard anything like that before.

Next moment, the three were whisked away at superspeed and were back in the lair. John looked around for a trash can and vomited in it.

Oliver looked at the man who had whisked them away- Barry Allen aka The Flash. "Sorry", said Barry to John. "It's okay", said John.

"You have a very fast heartbeat", said Matt, "You must be the Flash."

"And I guess you're the Devil of Star City", said Barry as he gave him his hand and said, "Barry Allen."

Matt shook his hand and said, "Matt Murdock. They call me the Devil of Star City but I prefer Daredevil." Felicity came in. Barry and Felicity greeted each other.

"So who was that guy?" he asked Oliver. "That was Vigilante", said Oliver, "And we almost had him."

"You almost had him?" asked Barry, "Because I think he was about to 'Scarface' you guys."

"Barry", said Oliver, "Is there anything I can do for you? Another evil speedster to help you with?"

"Maybe", said Barry, "But that's not why I'm here." "Then why did you run all the way to Star City?" asked Matt.

"Aliens", said Barry as all but Matt stared at him.

"Aliens?" asked Oliver incredulously.

"Aliens", Barry repeated again.

"I swear to God, Barry", said John, "My life was somewhat normal before I met you." Oliver seemed a little offended by that.

"I'm sorry", said Barry, "But they're real and from what Lyla has told us, they do not appear to be here for peace."

"Oh no", said Felicity.

"Lyla knows about this?" asked John. Barry said, "Lyla... yeah, she came to us and-"

John walked off. Thea came in.

"There was an alien attack on my Earth once", said Matt.

"Did you fight these aliens?" asked Oliver.

"The Avengers fought and defeated them", said Matt, "But some stragglers escaped the perimeter. I fought a few. That was 3 years before I started my career as a vigilante."

"Who're the Avengers?" asked Oliver.

"My Earth's Mightiest Heroes", said Matt, "They're really powerful. They used to make a difference."

"Used to?" asked Oliver.

"Yeah", said Matt, "There was an incident in which they failed to save many lives so the U.N. made a registration act called Sokovia Accords which required them to either register and do as the U.N. asks them to do or be forced to retire. It drove a wedge between them. The Avengers who did not support it are now fugitives from the law, sadly."

"That's unfortunate", said Oliver.

"I called up Thea", said Felicity interrupting them.

"I came here to get your sign on these", she said holding up some papers, "Before the City Council goes in to mutiny but it can totally wait." She then put the papers on the table and said, "Count me in."

"For what?" asked Oliver, "I thought you retired."

Thea said, "Yeah but these... these are aliens. Barry is going to need all the help he can get."

"Aw. That's so cute", said Felicity sarcastically, "You guys are gonna get together and fight some aliens- Have you all lost your goddamn minds? They are aliens and there's only 5 of you."

"Not if we get Stein and the others", said Barry.

"They're calling themselves the Legends", said Oliver.

"Egotistical, but catchy", said Thea.

"Do you know where they are?" Barry asked Oliver.

"I knew where they were", he replied.

"We're gonna need all the help we can get", said Matt, "All our friends capable of handling this must be brought into the fold. That includes your old friends and my allies."


A young man wearing red clothes with a red hood rode on a bike. He stopped when he reached his destination. As he got off his bike, he saw Oliver, Thea, John, Felicity, Barry, Cisco and a man he didn't know walk up to him.

He took off his helmet, revealing the smile of joy he was giving on seeing them all.

"Roy!" exclaimed Thea as she wrapped her arms around him. He hugged her back and said, "It's good to see you again, Thea."

He then looked at Oliver. "I'm glad you reached out to me", he said. "I'm glad too", said Oliver. Mentor and protege then hugged each other. He hugged John and Felicity too.

He shook hands with Barry and Cisco. He then looked at the last man and said, "I don't believe we have met."

"My name is Matthew Murdock", said the man, "I'm the Devil of Star City."

The two shook hands as Roy said, "So that's you. Nice to meet you." "Nice to meet you too", said Matt.

"What is this place?" he asked Barry as he looked around. "A hangar that S.T.A.R. Labs owns", said Barry, "Or technically, I own it."

"You should do something with it", said Thea.

John looked at the sky and asked, "So our time travelling friends are just supposed to pop up in the sky at this time and place?"

"This is the time and place I gave them", said Felicity, "They should be here-"

A ship appeared in the sky at that very moment.

"About now", finished Felicity.

"I didn't do drugs because I was afraid I would see weird things", said John.

Matt turned to Oliver who nodded.

"Barry, Cisco", he said, "Take me back to my Earth. There, I will convince my allies to come here and help us."

"Cisco", said Barry, "You ready?"

"Yeah, yeah", said Cisco in an annoyed tone as he adjusted his glasses, "I am not as fast as you but that doesn't mean I'm not ready."

Matt didn't need his superhuman senses to know that there was some tension between the two of them.

Looking at Matt, Cisco said, "I don't know what's cooler- The fact that you're a blind ninja or the fact that you're called the Devil?"

"Thanks", said Matt.

Barry asked Matt, "How are you going to recognize your Earth?"

"When I was first thrown on this Earth", said Matt, "I heard sounds from different Earths in the Multiverse. I think I will be able to recognize my own Earth based on that."

"This guy keeps getting cooler and cooler", said Cisco.

"We have to do this quickly", said Barry, "Because there's another stop we have."

"Where?" asked Matt.

"Well", said Barry, "Months ago I ran into an alternate Earth where I met an alien. If we're fighting aliens, we might need to have one of our own."

He then opened a breach and the three went into it.

Matt once again heard many sounds as he went through the portal. He managed to focus his hearing to hear what he wanted to hear.

"I can't risk having the Watchtower burn up on re-entry", said a man in a rough voice, "I'll have to guide it in, manually. Gentlemen... it's been an honor."

"My life would be a lot easier without us locking horns!" said a voice exactly like his, "But I'm not trying to do the easy thing but the right thing! And that's why the Kingpin must be allowed to return."

"It's you from another Earth", said Barry. Matt simply nodded at that before hearing a scared man saying, "What the hell! The guy's got a glowing fist. What the hell are you?"

"I'm the immortal Iron Fist", said a voice that Matt easily recognized. "Take me to this Earth", he said, "Quick!"

Barry and Cisco took him there. The two looked around as Cisco said, "Well hello Earth-199999."

"I didn't know there were this many Earths", said Barry.

The two watched as a masked man with a glowing fist fought a bunch of thugs. His fist deflected the bullets fired at him by the leader whom he knocked out with a flip-kick. Matt heard the whole thing.

"You're getting better", he said.

The man turned around to see him and his eyes widened in surprise.

"Matt!" he said, "How are you alive? Who are your friends?"

He took off his mask, revealing himself to be a young man with dirty blonde hair and a small beard of the same color.

The two shook hands as Matt said, "It's a long story. These are Barry Allen and Cisco Ramon."

He then turned to them and said, "This is Danny Rand."

Danny shook hands with both of them. "I'm glad you did not lighten up your fist while shaking hands with me", said Cisco, "Even though it looks really cool." Everyone laughed at that.

"Thank you for carrying out my request of saving the city", said Matt, "But there is an important matter that needs our attention. Call up Jessica and Luke. I have to explain everything quickly."

"Alright", said Danny.

"But before that", said Matt, "I think we need to buy a camera."


Later Jessica Jones, Luke Cage and Danny Rand sat in Colleen's dojo while Matt, Barry and Cisco explained everything to them. Their heads were reeling with everything they were hearing.

"So you were pulled to another Earth before the building fell on you?" asked Jessica, "Unfortunately for you, I'm not drunk so I cannot believe it."

"Please believe me", he said before turning to Cisco and saying, "Show them."

Cisco raised his hand and it opened a breach while the three gasped.

"Sweet Christmas!" exclaimed Luke.

"What the hell is that?" asked Danny.

"That is a breach to the Earth I went to", said Matt, "That Earth is facing an alien invasion. Now I know its not your Earth but the people there are innocent and I think you all like helping people."

Danny said, "Well, I believe you. I really want to go to another Earth and fight aliens. I'm in."

Luke said, "I have still not wrapped my head around the story of the kid and the dragon. This is far worse. But you're a fine, sane dude so I can believe you. There's not much going on in Harlem right now so I'm in too."

"Jessica?" asked Matt.

She looked at him and said, "You first broke my camera and now you've replaced it. But you did help me in saving Trish from that Japanese dude. So I guess I owe you one. In that case, I'm in too. Besides, I don't have much on my plate either."

"Great", said Matt, "Let's go."

The six then walked into the breach and reached Earth-1. Danny looked around and said, "I can't believe I'm on another Earth."

"It looks so much like our own", said Luke.

"Well", said Barry, "Meet the others. Me and Cisco are going to our other stop."

Barry and Cisco then went into another breach while everyone stared at Matt and his friends. Matt then said to everyone, "Everyone! Meet Jessica Jones, Luke Cage and Danny Rand."

He then said to them, "That's Oliver Queen and his sister Thea Queen. Those are their friends Roy Harper, John Diggle and Felicity Smoak."

He then realized there were new people around too. "Matt", said Oliver, "That's Sara Lance. There's also Mick Rory and Ray Palmer. And of course Jefferson Jackson and Martin Stein. They are the Legends."

Matt shook hands with all of them. "So you're the Devil of Star City", said Sara, "There's a cult in 2055 that worships you."

"Seriously?" asked Matt.

"Seriously", she said, "And there's another cult that worships Oliver as an incarnation of Apollo."

Oliver himself chuckled at that.

Mick looked at them and said, "So you're a team that comprises a blind ninja, a tall black guy, a kid with dirty blonde hair and a hot piece of ass."

"And who are you?" asked Jessica sarcastically, "Your team's dim-witted comedian/asshole?"

Mick looked a little embarassed. Everyone laughed at how this foul-mouthed woman had put down Mick.

They all went into the hall where they were introduced to Barry's other friends- Caitlin Snow, HR Wells and Iris West.

The teams then all stood a little separate from each other.

"So we have Team Arrow", said Felicity, "There's Team Legends and Matt and his friends. I think that's everyone."

"Nate and Amaya are watching the Waverider", said Sara, "The newbies."

A portal opened and Barry and Cisco walked out with an attractive woman who was wearing a cape.

"That was so cool", she said.

"Barry!" said Oliver, "I thought you were bringing in an alien."

"She is", said Matt, "I sense some things in her that are not in human beings."

"Everyone", said Barry, "This is Kara Danvers or as she is known on Earth- Supergirl."

"What makes her so super?" asked Jax.

"Yeah", said Jessica, "She can lift and throw heavy objects? I can do that too."

Supergirl flew up into the air and two beams shot out of her eyes. They hit the ground, creating the symbol on her chest.

"I'm convinced", said John.

"That I can't do", said Jessica.

"Sweet Christmas!" exclaimed Luke.

"Just like the Avengers", said Matt, "Powerful, even though she seems a little less impressive than Thor right now."

He then turned to her and said ,"No offense."

Oliver was suspicious of her. Aliens were attacking his Earth and this Kara didn't really make him feel any better about them.

Matt had a different opinion. He had respect for the Avengers and while there were alien invaders out there, people like Thor proved that not all outsiders were bad.

Kara then landed and said, "Okay. I think I have got this."

She walked up to Oliver and said, "Oliver-"

"Green Arrow", he said.

"Roy-"

"Arsenal", he replied.

"Thea-"

"Speedy", she told her.

"John-"

"Spartan", he said.

"Matt-"

"Daredevil", he supplied.

"Danny-"

"The immortal Iron Fist", he said.

"Quite a mouthful", she commented.

"Just call him Iron Clad", said Jessica which made everyone chuckle.

"Alright", said Kara, "Jessica and Luke."

She then turned to the Legends.

"Sara-"

"White Canary", she said.

"And Jax and Professor Stein?" she asked.

"Firestorm", the two said in unison.

"Ray?"

"Palmer. The Atom." Ray said as he raised his hand and smiled.

"And Mick?" she asked as he looked up from the burrito he was eating.

"Hmmm? Heat Wave", he said.

"And Caitlin, Felicity and Iris", she said as she walked up to the women.

"That's right", said Felicity as Kara cheered.

"Yes!" said Kara before asking Caitlin, "And you have cold powers but you can't use them?"

"You have powers?" asked Felicity.

"It's a long story", said Caitlin.

"Maybe we should get started", said Oliver.

Cisco nodded and showed them something on a screen. It did not look like a human. It seemed like some kind of zombie.

"It certainly makes those Chitauri assholes look like supermodels", commented Jessica.

"These are the Dominators", said Barry, "We do not know much about them but they're not friendly and they are not here for peace."

"And they're strong", said Kara as everyone looked at her, "I heard a lot about them when I was a kid. They came to my planet before I was born, experimented on my people, killed a lot more."

"Well", said Thea, "From what Barry tells us you're stronger than a locomotive."

"I have my strength as long as I have access to a yellow sun", said Kara, "It's where my powers come from."

"I think we should use Kara as a stand-in for training", said Oliver.

"Since when is Robin Hood calling the shots?" asked Mick.

"What I think Mick is trying to say is that it would be nice to know who is in-charge around here", said Jax before things could escalate.

"He's right", said Ray, "Maybe we should take a vote. Someone we can all trust."

"Fine by me", said Matt.

"My vote goes to Matt", said Danny, "He lead us all into battle against the Hand and made us triumph almost at the cost of his own life."

Matt appreciated what Danny had said. It showed how much he had grown.

"Well my vote goes to Oliver", said Cisco, "I trust him."

Even Oliver could sense the tension between Barry and Cisco.

"Thank you for the vote of confidence, Cisco", said Oliver, "But Barry brought us all together. I think it should be him."

"Fair enough", said Cisco though it was obvious he had an issue with it.

"Well", said Barry, "As team leader I think we should start out by..." he stopped as he realized he didn't know what to do.

"Doing a test run", said Oliver.

"Doing a test run", said Barry even though he wasn't sure what that was, "A test run."

"Against Supergirl", supplied Matt as he knew what Oliver was suggesting.

"Against Supergirl", said Barry, "A test run against Supergirl."

"Are we just supposed to pretend like we don't hear them?" asked a smiling Sara as she pointed at Matt and Oliver while everyone chuckled.

"Okay everyone", said Barry, "Suit up. Look alive. We're training to fight aliens by fighting an alien."

Everyone then started getting ready for training.


I think this is a good place to stop the chapter. I did what every good Arrow fic does- bring back Roy. I'm kinda surprised they didn't bring him back for the crossover.

And bringing the other Defenders into the fold was my plan right from the start. I think Jessica and Danny's reasons for deciding to help out are legit. I could not find a good reason for Luke. Danny has been portrayed as naive in the MCU mostly so I think this is how he would react. Anyways, they're all here now.

For some reason, I was bothered by Matt breaking Jessica's camera so I decided he should give her a new one.

This time, Matt heard DCAU Batman and his own Earth-616 self from the comics while going through the Multiverse.

Now for the first time, Matt and Oliver are going to disagree on something.

The next chapter will have more interactions. I did bring in the Defenders but that doesn't mean Matt will interact with only them. Up till now, we were getting an annual CW Arrowverse crossover. This is a crossover between CW Arrowverse and the Netflix corner of the MCU so characters from both of them will interact with each other. By the way, has anyone seen that photo of David Ramsey and Finn Jones?

Please review. I always appreciate your feedback.
