I don't own The Avengers or the Justice League. They belong to Marvel, DC, Disney and the Waner Brothers. This was a requested by Crazyboi23. I thought it was a good idea and I would like to give it a try. Aright, let's get this story started.

Captain America entered room followed by Thor, Hulk, Wolverine, and Spider-Man. "What's the situation, Tony." Tony Stark busy typing on holographic computer to turn around but he respond, "We had a breach in Stark Tower. Some one broke into my lab last night and stole a transwarp prototype and used it to break some of Earth's most dangerous Super-Villains and escaped with it into the same dimension."

"You intvented a transport to another dimension, please tell me you have an elevator to New York to Tokyo." Spidey Joked. "Spider-Man, this is serious." said Cap as he turned back to the inventor, "Do we have any leads?"

"Actually I already know who did it. The guy left a "IOU" when he took the device." Said Tony as he gave Cap the he's a paper with the IOU plus a drawing of Deadpool's mask. Wolverine then sniffed around the lab. "Yeah, he was here last night. I can smell him."

"But what does the Pool of Dead want with this tenghology?" Asked Thor. Spider-Man remembered his encounters with the merc with the mouth and said, "Someone probley hired him to do it. He a mercenary, right? So somebody paid him to break everyone out of pirson and then use the device himself to get out of the room before any of us could arrive to stop him."

"You could be right be right, Spidey. I'll see if he had any recent contacts and see if I can pinpoint who is behind the strings. In the meantime, you guys are going to have to follow him and stop all the supervillians he broke out and Deadpool himself before they can do any damage." Said Tony as he went to a near by desk and pulled out a small device. "Thank God, I always make a spare." he muttered to himself.

He then toss the device to Cap. He looked at the device and then turn to Tony and asked, "Are you sure sending Thor and Hulk, our biggest guns just us go after this mercenary?What if the Earth needs them?" Tony just smirked and said, "Skaar and Valkyrie, agreed to take their place while you were away. Plus, if Loki and Red Hulk are out there, you're going to need them."

Hulk smirked, he was proud that his son was finally an Avenger. He may not be as strong as him but with the combined Old Power from his Mother and his Gamma Strength still made Skaar a force to be reckon with. Hulk then turned to Thor and asked, "Glad they finically found someone to replace you, Goldilocks?"

"The Son of Odin is irreplaceable!" Thor said proudly, "Thou, is glad that Valkyrie agreed to watch Midgard while I'm away. I bet she will be better than your brute of a son by far."

Hulk the punch Thor and said, "Talk about my son like that again and I'll smash you." Hulk threatened as Thor got back his feet. Thor, prepared to fight the Hulk, started to swing his hammer. Before either of the could charge Cap opened the portal in between them as Tony said, "Guys, if you have to fight. Please do outside my building. I'm fixing it, when we fought Galactus."

Spidey was still unsure if he should go through the portal. He still had a job at the Daily Bugle and he hadn't told his Aunt he wasn't going to call for awhile. Tony saw this and gave him a device that looked like the latest iPhone. "Don't worry. I told the Bugle you quit and got a job a Stark Industries and told your aunt your doing a job for me across the world. Also the phone I gave you works across detentions. You can talk to your aunt when ever you like to."

Peter was relived. Even since he told the Avengers who he really was, they made sure that his aunt would be safe if ever Super Villain found out who he was. He didn't want to repeat what happened with Gwen and the Green Goblin again. "Well, action is my reward. Let go save new Earth from Deadpool."

Meanwhile on New Earth, Deadpool just sat on his chair for the apartment he bought. "Alright, New Earth means new life." he said.

"The crimes, assinations, and other illegal stuff we did never happened here."

"That means we can finally prove to the world and comic book readers that we do have what it takes to be a superhero."

"That's right, after that job we took, gave me the idea to start a new life, now all we have to do is wait." Said Deadpool to his voices in his head.

"What!? We have to wait!? Why!?"

"You see but silence, the TV speaks." Said Deadpool as he turned on the news. He saw senators arguing amongst themselves if they should get rid of there Nuclear Missiles or not. Just then a former astronaut spoke, "...when I was an astronaut on Mars, I survived an experience which profoundly changed my life. Looking at Earth from that distance I saw for the first time how small and fragile our planet is. It's fate is in our hands. Ladies and gentlemen, that is a responsibility we must not take lightly. Therefore, today I propose a bold, new solution for peace one that would use a force more powerful than any before a force dedicated to the good of all mankind a force known to all as Superman."

Superman then entered the room, and there was talk amongst the other senators in the room.

"Wait, this looks familar..."

"Yes, but ssssshhhh..." Said Deadpool. As he muttered, "Can't believe I said that."

"With all due respect, we can't entrust the security of the entire world to one man." argued the General. Superman, the responded, "I understand your feelings, General. When Senator Carter first approached me, I was reluctant to get involved but after meeting with him and his advisors I became convinced that I could make a difference.
I have fought hard over the years to earn your trust. And I solemnly swear to all of you that I will continue to uphold the ideals of truth and justice not just for America, but for all the world."

"Now I remember this. This is when the aliens attacked Earth..."

"...and the three part special of how the Justice League was born."

"Wait, your not think what I thinking you thinking, are you?"

"That's right. When they assemble, we help. That will make us an official member of the Justice League!" Deadpool said as he put his fist of his hips.

"Oh... Now I see why we're waiting. We're gonna be member of the Justice League! I'm so excited!"

"Clam down or probably kick us out before they even assemble. "

"Yes, we just sit patiently in the comfy chair and watch the news until they attack." Said Deadpool as he continued to watch the news. "It's been six months since Senator J. Allen Carter's dramatic disarmament plan was ratified. While Superman has been disarming hundreds of deadly warheads public support for the plan has swelled." said a reporter.

"Superman rocks!"said one of the people they interviewed. "Yet some remain skeptical..." The reporter continued.

"Hey, the big guy's heart's in the right place, but give me a break." Said Flash as he ran around the reporter a few times. "And even I can 't be in five places at once."

"Still, with more missiles dismantled every day most of us will sleep better knowing|that Superman is watching over us." The reporter finished.

"You guys don't think they going to find out what we did to get here?"

"Impossible! What make you say that?"

"Well, one they're going to get suspicious when unfamiliar Super Villains start showing up. Another, is that the story is labeled under both Justice League and Avengers fanfiction crossover. They might have followed us here, and the might not be too happy after what we did to get here."

"It's probably just a typo. Since I took the only transwarp device so there's no way..." Before he could finish his sentence a portal opened in front of his TV.

"Wow! This 3-D is Amazing. It actually looks like a portal is opening right in front of us!"

"That because there is, genius." intelligent voice said sarcastically. Just then Captain America, Thor, Hulk, Wolverine, and Spider-Man walked out the portal. "...Unless they had a spare. I hate you, author. Hey, Spidey, Wolvie, Hulk, Thor, Cap. It's been a while since we been in the comics."

"Actually we're all in one right now except for Logan."

"What! When! And why not Logan?"

"Avengers X-Men Axis. It when the good guys are the bad guys and the good guys are the bad guys. Except for Spider-Man, Captain America, and Nova. And haven't you heard Wolverine's dead right now."

"Yeash! Things sound screwed up in the comics right now."

"I know right." Deadpool muttered. As Wolverine grabbed Deadpool by the throat and growled and said, "Alright Wade enough games! Who hired you and who else did you break out?"

Before Deadpool could answer, everything the room began to shake. Everyone began to lose balance before the looked at the Hulk. Hulk just shrugged, "Wasn't me."

"Uh, Cap. You might want to see this." Said Spidey. Everyone turned to the TV to see white aliens were invading and the skies where turning black. The headlines on the screens was, "Where is Superman?" Wolverine then turned back to Deadpool, "Start talking Deadpool. What the hell is going on here? Who this Superman there talking about? Say anything I don't like and I'll gut you! Got it!?"

"Long TV episode sort ship shaping aliens are invading and Superman is one Earth's greatest heroes and is helping Batman rescue another alien and gather Heroes to fight this threat. Is that good Wolvie" Deadpool said. "Great it's like the Skrull invasion all over again. So, Cap. What's the plan?" asked Spider-Man.

"The way I see it. The Earth is in trouble again and this Superman might need some help, we can then ask his help to track down the other criminals." said Cap. He turned to Deadpool and said. "As much as I prefer you to be behind a cell, we need all the help we can get. So can I expect you to behave?"

"Say what now?" asked Deadpool. He wasn't sure he heard him right. Neither did Wolverine, "Please, tell me your joking, Rogers, because if it is I'm not laughing."

Deadpool then puts an arm on Wolverine shoulder and said, "Relax, Logan. I want to redeem myself by become a hero. I promise to behave a help capture every super villain I broke out. Cross my heart and hope to die. Do you want be to pinkie swear too?" Wolverine then looked to Cap and he nodded. Before he let go of him he threatened, "If back stab us and I'll take you and apart and feed you to Hulk."

Wolverine then let go of him. Deadpool struggled to get back on his feet, trying to catch his breath. Once he did Cap asked, "Alright Wade, How do we find this Superman?"

"Don't worry the Martian will contact us any moment now." said Deadpool. Before anyone else could respond, they all started to he a voice inside there head.

"This is a message to a Super heroes near by. My name is J'onn J'onzz. If you are hearing this Superman, Batman and I are under attack by the Invaders. When need you help. I'm giving you our location now."

"Did we just get a third voice inside our heads?"

"Doubt it. See how the others heard it too, it must have been a telepath."

Cap then turned to Thor. "Can you create a portal from here to were the others are?" Thor shook his head, "Nay, Captain my connection to Asgard has been cut off. I can fly some of us there, while Hulk carries the rest."

"I have better better idea. I have a telport belt..." He prove this by teleport away and then teleport back with a soda. He tries to drink it, without taking his mask off, "Dang it. Well anyways I can just teleport us all there myself."

"Wait, we can teleport other people as well?"

"Well if the author actually read more of our comics, he would know how it works better. So, he just saying it can teleport a group as well. It's fanfiction the author can write whatever he wants to."

"Wait, so we can write us having a hot girlfriend? We need to get our own site going."

"It's on my to do list" Deadpool told his voices. Cap just stared at Deadpool and then turn to Spider-Man "Spidey, is this a trap?"

"My Spider- Sense hasn't gone off so unless he's possessed by a evil symbiote, it's not a trap." Spider-Man replied. The first Avenger nodded and then turned to Deadpool. Alright Deadpool get us there. Now!"

Deadpool then saluted Cap and said, "Sir, yes, sir. Now ever hang on me like a port key boot." They all held on to Deadpool as he teleported them out.

Meanwhile, Batman was flying J'onn the Batwing when they got hit by one of the invaders ships. The were going to crash when a green light caught them. "Whats going on", he thought aloud.

"Help has arrived" replied J'onn J'onzz.

Outside, on a cliff, stood the local Green Lantern of Earth. This Lantern was John Stewart, a former marine, now the current Green Lantern of sector 2814. More fighters came around, blasting at the Lantern. Then, the next arrival hit, and it was Hawk Girl, Shayera Hol, a Thanagarian warrior, with an Nth metal mace. She flew down to destroy any fighters she could.

"Hawk Girl? What's she doing here?" Batman turned to question the Martian, but he levitated out of the back seat. Green Lantern lowered the Batplane to the ground, and Batman hopped out.

"Sorry I'm late. There was an uprising on Rigel 9." The Lantern said, as all the fliers formed up, and moved out. Superman grabbed a fighter, and swung it around, building force for a few seconds, and then releasing it to destroy a squad of the enemy invaders. Lantern projected force through his ring falling back on his Marine Corp training of projectile weaponry.

Supergirl, Superman's cousin, then grabbed ship and threw it into another. Superman then flew to her, "Kara? What are you doing here?" She just smirk and said, "School was cancelled due to an alien smashing through the school. So, I thought you could use some back up.

Hawkgirl, Superman and Larntern destroyed as my fighters as the could until only a few remained. Hawk Girl got hit but then a girl in a one-piece suit with the colors of the America flag got in the way saying, "Allow me."

The fighter tried shooting her and reflect the lasers at the ship destroying it. The others saw this and Lantern looked over at Superman, questioningly. "Who's the rookie in the tiara?"

"I'm not sure." Lantern nodded grudgingly.

"Thanks", Hawk Girl said to the unknown woman, as she knelt down to help her up. The were all about to finish the rest of the fighters when a flash of light and revealed five other heroes. Captian America took the charge, "Thor take out their gunships." Thor nodded the flew into battle, Cap the turned to Spidey, "Spider-Man, draw there fire."

"Sure thing." Said Spidey as he use his web to swing on to a gunship. "I just love being the target."

"Wolverine, take Deadpool and..." But Wolverine interuputed him, "Hold it, Boy Scout. I don't take orders from you." Wolverine the run on to a gun ship with Deadpool following him saying, "Hey Logan. Wait for me."

Cap then turn to the Hulk and said, "and Hulk..." Hulk then turned to Cap. "...smash." Hulk grinned and started to tear the the gun ships apart. Thor flew right there on destroying some of the other fighters and start shooting at him. One hit but he shrugged it off saying, "soulless creatures! How dare you strike the Son of Odin!" Thor then struck it down with lightning.

Spider-Man who saw the explosions and torn up fighters just said, "Show offs." He then crawled on top the ship and knock, "Pizza Delivery!" The pilot then opened up and point his gun and the Wall Crawling. Before he could pull the trigger, Spidey webbed his gun and the triggerman to a near by tree. Spidey then swing away. Supergirl watched the whole thing and said to herself, "That was cool but Spider Powers? Ew!"

One of the pilots tried shooting at Spider-Man but he kept dodging until Deadpool teleported into the ship and taped the alien on the should, "Hey ugly, hope you like pineapples." He then tossed him a grenade without the pin. Deadpool then teleported out before it explode. Then the grenade blew up, killing the pilot and destroyed the ship.

"Ah! Got to love the classics."

One of the ship tried to shoot shoot at Cap but he blocked every shoot from his might shield and then he threw his Shield and it cut off one of the wings and went right back to the Man Out of Time like a boomerang. The ship lost balance and crashed. Spidey then joined him. The turn to see Wolverine cut down the invaders and he crashed with there ship near Batman and J'onn. "That dude scares me, sometimes." Said Spidey. Cap nodded and went with Spidey as they join the other heroes.

Flash then joined up with them, "Hey, Bats. I think you dropped this." As the others regroup as Wolverine walk out the remains of the destroyed ship like nothing happen, in rack all of his injuries where already healing. The heroes of this Earth just watched in amazement but then Wolverine just said, "What are you girls looking at?" Then the just turned to the other new heroes and Flash just stared at girl with the tiara, "Whoa. Where have you been all my life?"

"Themyscira." She answered causally

"The home of the Amazons? I always thought it was merely a legend." Said Spidey. Supergirl nodded and said, "Ditto."

"I assure you it's as real|as the ground on which we stand." She contenuied. "I am Diana, princess of the Amazons."

"Pinch me. I must be dreaming." Said Flash. Deadpool then pinched him. "Ow."

"Not dreaming dude but once this is over, one of the days, I going find that island." Said Deadpool as he dreamed about going there.

"That kind of stuff only happens in our dreams."

"...At least till, Paradise Lost."

"Themyscira is protected by the gods but I couldn't stand by while the rest|of the world was in danger." She explained. Batman then turned to the other heroes, "and the rest of you are?"

"Well I'm Spider-Man and this my hairy sidekick, Wolverine." Joked Spider-Man as introduced himself and Wolverine. "Don't push it, Web head." Said Wolverine. Supergirl giggled at his joke and Flash grinned, "Finally another comedian."

"That makes three of us. I'm Deadpool. Rhymes with no school, too cool and..." Puts on a Wolverine like mask and said in a low dark vocie, "...I'm the best there is at what I do...ool."

"Really you did the introduction of us from Ultimate Spider-Man."

"You mean the one where we sound like Ron Stoppable."

"Yeah, just go with it." He said to his voices. Batman glared at Deadpool, he did sound like he belonged in Arkham. Thor then spoke, "Greetings to you warriors of Earth. I am Thor the Thunderer, Son of Odin, Prince of Asgard, and I proudly say I am I an Avenger!"

"Thor, I am honored to finial meet you." Wonder Woman said with a bow. The Amazons may have worship the Greeks but the knew the Norse as will and respected them too. "I'm Captain America and this is Hulk..." Hulk nodded. "...We all have come from a different Earth."

"A different Earth? Cool! What's it like?" Flash asked. "Similar to this one but different." Said Spider-Man

"It was lucky you all showed up when you did." Said Superman. "No, not luck. I telepathically summoned them." Everyone turned to the Martian. Cap then said, "alright care to give us the situation."
