A/N: Gonna try and wrap up the team gathering in this and we might get a cameo of a rather special guest in either this chapter or the next. This guest will be a rather familiar and special guest. There's actually going to be more special guests, excluding everyone who was mentioned, name-dropped, and shown in chapter 18. On with the story.

Also, I just wanna say, this cinematic universe/series I'm making has three names (if there's anything you wanna call it).

EU (Expanded Universe, full name is MDEU or Marvel/DC Expanded Universe but EU is easier)

Legends (Another name for this series, not like the Legends of Tomorrow, just Legends)

Worlds Collide or WC (The third and final name, also the original technically)

Response to Guest Reviews:

Chloe: Thanks.

Earth 199999

New York City

Hell's Kitchen

"So how'd you say you knew this guy?" May asked as she and Daisy stood outside the door of a certain room inside a building. The door to the room had the letters 'Nelson and Murdock' branded on it.

"We grew up in the same orphanage," Daisy explained. "I met Matt at St. Agnes. When he was nine, he lost his sight in some sort of car accident. The accident took his vision away but it heightened his other senses. He became Daredevil a couple or so years ago."

"You said he was a good fighter?" May asked.

"The best," Daisy said as she glanced at May with a smirk. "Maybe even better than you."

May gave her a short glare as Daisy cleared her throat.

"Right," Daisy said. "Let's get to it-"

"Daisy," May interrupted. "Do you love him?"

Daisy blinked twice. "What?"

"Barry. Do you love him? Does he make you happy?"

"Yeah…May. He does. I've never felt anything like what I've felt with him and he's made me happier than anything."

"Good," May said lightly. "Because if he doesn't, I'll beat him to an inch of his life with a shovel and bury him with it."

"Yeah, thanks, Mom." Daisy sassed as May suddenly felt mentally uneasy, the last word of Daisy's sentence echoing in her head.

"Let's get this over with." May said.

Daisy then clenched her hand into a semi-tight fist as she knocked on the door three times, her knuckles meeting the wooden frame of the door. There were a few seconds of silence before May and Daisy heard a voice echoing from inside the room.

"Come in." a familiar voice said as a feeling of familiarity began building up inside Daisy.

Daisy turned the knob as she and May walked through the opened door. The two of them entered as they saw a rather good-looking and relatively tall blind man standing just a few feet away from them. The man had red glasses with round glasses, specific glasses that were meant for the blind. He had short brown hair and was dressed in a gray business-casual suit. His suit was well-put together and he stood tall with his walking stick in front of him as he held it tightly with both hands, the opposite end of it resting on the ground. Daisy slightly smiled as she let out a huff upon seeing Matt for the first time in months. Almost a year.

"Hey Matt," Daisy said.

Matt furrowed his eyebrows before his eyes grew large in shock. "Daisy?"

"It's good to see you," Daisy said as she and Matt embraced each other, the both of them hugging for a moment.

"I'd say the same," Matt replied as he and Daisy. "But then again, I never have."

Daisy chuckled. "Matthew Murdock. Always with the blind quips."

"So, uh, what brings you here?" Matt asked.

"I need your help," Daisy as she and May exchanged glances. "We need your help. And not as Matt Murdock. As the other guy."

Matt furrowed his eyebrows as he pointed to May. "Does she-"

"Yeah," Daisy interrupted. "We need your help and it's a pretty complicated story."

"What're we going up against?" Matt asked.

"Aliens," Daisy revealed as Matt tilted his head in confusion. "In a different universe…"

Inside the Sanctum Sanctorum of New York City, at the top of the grand staircase, Stephen Strange and Wong stood next to one another. Strange was dressed in his blue robes, the Cloak of Levitation hanging from his shoulders, the Eye of Agamotto, which held the Time Stone, hanging off his neck. Wong stood next to him, on his left, wearing his usual brown, dark robes. Suddenly, at the other end of the stairs, a large blue portal opened as Strange and Wong stared at in surprise, two of them went halfway down the stairs as they stopped, the both of them forming orange-colored, magical mandalas with their hands. Then, two grown men jumped through the portal as it closed behind them. The two rose to their feet as Strange and Wong stared at one of the men in confusion, instantly recognizing him.

"That's a handy device you got there, Cap," Phil Coulson said as he noticed the two sorcerers standing not too far away from him.

"Captain America?" Strange said in confusion as he and Wong stood down, the two pairs standing a few stairs away from each other.

"We're sorry to disturb you," Steve said apologetically. "But we wouldn't be here if it wasn't urgent. We're looking for Stephen Strange."

Strange raised his hand. "That would be me. What can I do for you, Captain Rogers?"

"Steve," Steve corrected. "We need your help. Barry Allen told us you could help."

"Barry?" Strange asked. "As in Barry Allen from Earth 1."

"You know him?" Coulson asked.

"He trained with us not too long ago," Wong explained. "He was powerful and skilled. The Ancient One and I taught him the ways of the Mystic Arts."

"You taught him magic?" Coulson asked incredulously.

"We did," Wong confirmed with a nod. "And not just magic. Combat. Hand-to-hand and with almost every kind of weapon ever made in the mystic arts. Allen was exceptionally skilled and gifted. Especially with weapons. Every master across the Sanctums was defeated by him in sword combat."

"Rumor had it that he even beat the Ancient One in a sword duel," Strange added. "All without his speed. Just pure skill and talent."

"Cool story," Coulson said dryly.

"Right," Strange said immediately. "What is it you said you needed help with?"

"Aliens," Steve explained as Strange and Wong exchanged glances with one another. "Aliens are invading Earth 1… and we need your help, Mr. Strange."

"Please," Strange said, tidying his cape. "Dr. Strange."

A flash of orange lightning appeared in Thea Queen's old apartment as Barry, Oliver, and Diggle appeared inside. Barry was dressed in normal clothes, a long-sleeved blue t-shirt with his sleeves rolled up right under his wrists, black jeans, and blue running shoes. Diggle was in his Spartan suit and his helmet, Oliver was in his Green Arrow suit, his hood pulled back and his mask hanging off his neck, his face exposed. Diggle quickly removed his helmet as he began to run to the balcony.

"Sorry," Barry said.

"It's okay," Diggle replied quickly before he reached the balcony, vomiting extensively.

"You okay?" Barry asked as Oliver cracked his neck.

"Yeah, I'll be fine," Oliver said. "Have you gotten faster?"

"A lot actually," Barry said as Felicity and Thea entered the apartment area. "Hey Felicity."

"Hey Barry," Felicity said. "You've been gone for a while."

"Yeah," Thea added as Diggle, unmasked, walked back into the apartment living room. "A really long while."

"I swear, Barry," Diggle muttered. "My life was some level of normal before I met you."

"So you've said," Barry replied.

"Barry," Oliver began. "Where've you been? Bruce told me you were training with him for a month and then you disappeared for a week."

"Bruce?" Thea asked as she, Felicity, and Diggle stared at Oliver and Barry in confusion. "Who's Bruce?"

"Bruce Wayne," Barry explained. "Long story short, I went to Gotham City to train with him. I stayed and trained there for a month. Then, I tried to run back with the tachyon. I ended up opening a portal and found myself stuck in an alternate earth two years in the past. For two years, I was stuck there but after stopping another evil speedster, I was brought back here."

Everyone stared at Barry blankly as the trio tried to process the information Barry had dropped on them. Barry wanted to laugh humorlessly at the looks on their faces. The information he had told them wasn't even half of the full story.

"I have so many questions," Felicity said out of the blue.

"Yeah, like…" Thea began as she chuckled with a laugh. "What exactly was Bruce Wayne teaching you? How to be rich? How to get girls?"

Oliver and Barry looked hesitantly at each other as Diggle, Thea, and Felicity noted some form of secrecy between the pair.

"Should we tell them?" Barry asked.

"We trust them," Oliver said as Barry nodded. "If we do, Bruce will. We should tell them. They're gonna need to know pretty soon."

"Know what?" Diggle asked as Barry and Oliver faced the trio.

"Batman is Bruce Wayne," Oliver deadpanned as he and Barry waited for the explosion of shock.

For a couple moments, there was nothing but silence in the entire apartment. Then, Thea started chuckling.

"Okay," Thea said, smiling as her chuckling came to an end. "Funny joke."

The looks of seriousness and sounds of silence from Oliver and Barry, however, made her, Felicity, and Diggle stare at them incredulously.

"Oh my god, you guys are serious." Felicity spammed.

"Oliver, how long have you known about this?" Diggle asked, him and Felicity feeling a somewhat feeling of betrayal at the thought of Oliver hiding Bruce's identity from them.

"A few years," Oliver revealed. "Me and Barry. I'm sorry - why is that so important?"

"Oh I don't know," Felicity said sarcastically as she fiddled with her fingers. "Maybe 'cause we're…you know, your team and this is part of the stuff you should kinda tell us."

"Felicity, Diggle," Oliver said sternly as the pair shut up immediately. "This was not something you needed to know. This was not something I needed to tell you. I kept this from you because I felt and knew that it wasn't necessary for you to know. There is nothing wrong with that and if you think otherwise, save it. I don't want to hear it. Not at all."

Diggle and Felicity were in silence and surprise. Barry and Thea raised their eyes in surprise, they hadn't seen Oliver take control of his team and his position as leader in quite a while. Usually, he was more lenient and often let Felicity and Diggle undermine him with relative ease. This time, however, things appeared to be different. Barry and Thea exchanged glances as they shrugged.

"You still haven't told us what you're doing here," Thea said to Barry, changing the topic of conversation.

"And why you stopped us from catching Vigilante." Oliver added.

"Okay, first off," Barry began. "I saved you two from early graves. Second off…it's aliens."

"Aliens?" Oliver asked.

"Aliens?" Thea, Diggle, and Felicity asked simultaneously.

"Aliens," Barry confirmed. "They've arrived. And they're about to attack. We need everyone we can get. I've been going around everywhere. Daisy and a few of my other new friends are gathering a few people of their own."

"Daisy?" Oliver asked in confusion.

"Yeah, who's Daisy?" Felicity asked.

"My fiance," Barry deadpanned as the four raised their eyes in shock. "From that other earth. I proposed to her last night. Also, I have a one-week-old son named Luke."

"How long were you on that other earth again?" Thea asked.

"Two years," Barry said. "Time and space travel."

"Right," Oliver said. "One sci-fi story at a time. Bruce is on point with Dick and Jason?"

"Dick is with him at our new base," Barry explained as he turned to Oliver. "Jason went off to Keystone. Said he knew someone who could help."

"How many new friends do you have?" Oliver asked.

"Hopefully," Barry said. "Enough. Didn't you know Sara and a few of her new friends?"

"They call themselves the Legends," Oliver replied.

"Egotistical and a little cocky, but still catchy." Thea commented.

"Know where they are?" Barry asked.

"I know where they were." Oliver said in a 50-50-like voice.

"I know there's been a lot of difficulty between us…" Steve said as he, Daisy, Sam, Bucky, Strange, Coulson, Matt, and the agents of S.H.I.E.L.D. were inside the Avengers facility, two men were standing in front of them. One of them was relatively old, past his 40s and almost six feet tall. The other was a young teenager, fifteen years old, at around five feet and five inches of height. "But what's happening on Earth 1 is serious. I wouldn't be asking if it wasn't absolutely necessary. There's been tension between us but now's the time we have to solve it. We need your help but we can't do it with what's been going on between all of us."

The older man lifted his head up as he instantly glared at Bucky, who tried to avoid eye contact. The man instantly clenched his fist as he glared at Bucky in rage. The young fifteen-year-old beside him awkwardly looked back and forth between Steve and the others and the older man.

"Well…" Tony Stark said as he slipped his hands into his pocket, looking through the team in front of him. "You said something about aliens?"

"Aliens?" Peter Parker said as he began stirring with excitement. "Like real aliens? From outer space? Is it like E.T.? Or are we talking about Star Wars?"

"We're seriously doing this?" May muttered to Daisy as Steve continued conversing with Peter and Tony.

"We need all the help we can get," Daisy said. "Even if it means getting help from him."

"Daisy," Matt said in a warning voice. "He's part of the reason you had to go rogue. And you were pregnant then."

"We can't trust him," Fitz said.

"Maybe not," Daisy admitted. "But we need to trust Cap. If he feels that Tony can help us, then maybe he can."

"Alright Cap," Tony said reluctantly. "I'm in."

"Hey, me too." Peter added as Steve and Tony stared at him incredulously.

"Not happening." Tony said quickly as Peter frowned.

"I'm sorry, son, but this is too dangerous," Steve said apologetically. "You're just a kid. This is not something you should be doing."

"Oh c'mon, Mr. Stark," Peter whined. "I can help. You know I can."

"I'm sorry," Tony said sarcastically. "Did you miss the part where they said there was an army of aliens?"

"Yeah and did you miss the part where they said they needed all the help they can get?" Peter shot back.

Tony sighed as he let out an exhale. "You're gonna try and come either way, aren't you?"

"Y-yeah," Peter said sheepishly.

Tony groaned. "Kid, one of these days, you've gotta listen to me. Look, you can come, but you follow my lead and stay away from big fight. You're just back-up, got it."

Peter grinned with excitement. "I won't let you down, Mr. Stark."

"Is that everyone?" Strange asked.

"Everyone we've got from this earth," Sam confirmed.

"Let's head back to Earth 1," Steve said as he pulled out his extrapolator device.

"He is so cute," Thea said in awe as Barry swayed baby Luke in his arms, him, Oliver, all of Team Arrow (including the recruits), Clint, Natasha, Wanda, Dick, and Team Flash inside the new S.T.A.R. Labs facility they were based in.

"Thank you," Barry said as he looked down at Luke with a smile. Luke cooed in his arms.

"How old is he?" Oliver asked.

"Little over a week," Barry answered, lifting his head up to face Oliver and everyone else.

"Congratulations Barry," Diggle said. "Welcome to the club."

"You are officially a father now," Felicity added.

"By the way," Rory said sheepishly as he scratched his head. "I'm really glad you reached out. It's so cool to meet you."

"Likewise," Barry replied as he eyed Rene, Rory, and Evelyn. "I've been wanting to meet Oliver's new recruits."

"So this kid…" Rene said slowly. "He's like you? Metahuman?"

"Sort of," Barry said. "Half-metahuman, half-inhuman."

"Inhuman?" Curtis asked in confusion.

"Luke gets his speedster abilities from me," Barry explained. "He's half-metahuman from my side. From his mother's side, he's half-inhuman. They get their powers when they're exposed to dust from a crystal called Terrigen."

"So he can do everything you do and more?" Clint asked.

"Potentially," Barry said as he looked down at Luke's baby blue eyes. "He could become even faster and more powerful than his parents."

"Damn," Diggle muttered. "And here I thought my chances of a normal life were gonna come back."

"So when do we get to meet this 'Daisy' person?" Thea asked curiously.

"Soon," Barry confirmed. "She'll be back with quite a lot of reinforcements."

"So where's Bruce?" Oliver asked.

"He's still in Gotham," Caitlin replied. "Said he knew a friend who could help out."

"Also," Felicity said as she noticed Clint, Wanda, and Natasha. "I don't think you've introduced your new friends."

Barry nodded his head. "Everyone. Meet Clint Barton, archer, known as Hawkeye. This is Natasha, the Black Widow, former Russian spy. And this is Wanda, the Scarlet Witch. They're part of the Avengers."

"The Avengers?" Thea asked, emphasizing the name.

"Well, we used to be," Wanda said.

"We kinda split." Clint added.

"What? Like the Beatles?" H.R. asked.

"A lot worse," Natasha replied.

Then, two large blue portals opened a few feet away from everyone as from the first portal, Cisco, a suited-up Kara, and a suited-up Clark jumped to the ground, the breach closing behind them. The second portal saw Daisy, Sam, Bucky, Steve, and multiple other people coming through. Team Flash and Team Arrow stared in surprise at the number of people that were currently present in the room.

"This is one heck of a team." Evelyn muttered.

"A team?" Diggle said incredulously as he scoffed. "A team is five-to-ten people. This. This is a whole damn army."

"I'd call it a cavalry," Hal Jordan said as he, Diana, and Arthur walked in, standing by everyone.

"This team is badass!" Arthur declared, his voice growing at the end of his sentence.

"It better be," a man said as he, Bruce, Jason, and a teenage girl with white hair walked in.

"I'm sorry, who are you?" Oliver asked.

"Name's Logan, bub," the man replied. "But they call me the Wolverine."

"He's a friend of mine," Bruce explained.

"This is Felicia Hardy," Jason said, jerking his head to the teenage girl beside him, she appeared to be no older than Peter. "She calls herself the Black Cat."

"That's a really cool name," Peter said sheepishly as he cleared his throat before he and Felicia made eye contact.

"You think so?" Felicia asked as she smirked at Peter.

Peter blushed. "Y-yeah. I-it's cool."

Felicia nodded with a slight grin.

Then, through the large hangar door, everyone could see the Legends' large time ship appearing out of thin air as it began to land on the ground.

"Best team-up ever." Felicity said under her breath as she and H.R. high-fived.

"That should be everyone," Daisy said.

"Alright," Barry declared as he continued swaying Luke in his arms. "Let's get started."

Several hundreds of thousands of feet in the atmosphere, four ships were looming over the earth in space. Three of the ships were relatively smaller as they were only the size of a small city. The fourth ship, however, was the largest of them all. It was the size of the moon as it could be observed from the surface of the earth. Inside the mothership, a green alien creature almost completely covered in advanced metal armor and technology stood tall, looking at the earth through the front of his ship. His arms were behind his back, metal tentacles stretching from different spots of his armor, from his arms and his back. The creature turned around as he faced two human-looking men in front of him. One of them was dressed in a red-black suit, the other in a white armor suit, lined with gold metal.

"I trust you two will be valuable resources in this mission of mine," Brainiac, the Collector of Worlds, said.

"Certainly," Eobard Thawne said with a grin.

"We have common interests," August Heart said

"We do," Brainiac confirmed. "Barry Allen is an exceptional resource. As is this world."

"And we have the perfect bait," August said, grinning evilly as he looked down at a human baby that was covered in blankets, resting in a small pod that Brainiac had made for it.

"Allen and Daisy had a daughter too," Thawne whispered.

"They did," August admitted. "And without either of them even knowing, just like that, I stole her from them. Took her from Earth 199999 and brought her here."

August then walked closer to the baby as he traced his finger through the blankets the baby was covered in. The baby opened her small baby eyes as she saw August's face.

"If I'm not mistaken," August began. "Her name is Emilia. At least, that's what it would have been if poor mommy Daisy had the chance to properly name her. And she will be exactly what we need to break Barry Allen…"

A/N: I'll end this chapter here. Hope it was enough for you guys. At least now, I've wrapped up the team-up, so next chapter onwards, there will be fight scenes.

For Daredevil, it's been confirmed that season 2 of the show takes place after Agents of S.H.I.E.L.D. season 2 and the first Ant-man movie and before Captain America: Civil War. So Matt has already lost Elektra, because technically speaking, it's already happened. Season 3, on the other hand, is confirmed to be before the snap but there's no specific time beyond that. The Defenders (which show-cases the beginning of DD s3 and Matt's 'death') is said to take place a few months after season 2 of Daredevil. For the sake of this story, let's just say it takes place a month or so after my version of Invasion, with Daredevil season 3 happening at some point before Infinity War.

If you want to put faces to Logan and Felicia, the castings are: Hugh Jackman for Logan and Anya-Taylor Joy for Felicia. Hugh is always going to be Logan for me, that will never change as he is too good and too iconic in the role (and also too damn handsome, LOL!). Anya has multiple pictures of fan-casting for her, so if you want to really put Anya's face to Felicia/Black Cat, just look up 'Anya-Taylor Joy Black Cat'.

I know the whole Emilia thing is a shock. I was originally planning on having both Luke and Emilia to be together but I forgot to include Emilia, so I'm including her now through this. Yes, Emilia and Luke are twins and both are Barry and Daisy's children.
