What if Godzilla was in the MCU?

Here we see Tony Stark, Steve Rogers, Thor and the other Avengers are going to a press conference at the helicarrier and they're sitting with Director Fury about a serious issue of a possible Avengers level threat.

Tony: "What's all this about?"

Nick: "We have a possible Avengers level threat on our hands here Avengers."

Scott: "Wait, you mean there's another Avengers level threat? Like an army or some douchebag with phenomenal cosmic power?"

Nick: "Actually, this one is not from space. It's from Earth."

Bruce: "Like an Ultron 2.0? Cause I hope so it would not be tough to take down like last time, unless it's like how the iPhone 6 is basically the iPhone 5s."

Steve: "What do you mean?"

Bruce: "You see when the iPhone 6 came out, it's kinda like the iPhone 5."

Tony: "Bruce, can you stop talking about the iPhone."

Bruce: "Sorry."

Nick: "Anyways, there was some high amounts of nuclear radiation in the water coming from a single source."

Then puts up a projection on the board and shows a large creature that is reptilian in appearance and it looks like it's 393 feet tall.

Wanda: "That is a big lizard."

Peter: "Wait, we're going up against a kaiju?"

Thor: "What's a kaiju?"

Peter: "It's a giant monster that the Japanese call."

Thor: "I see."

Nick: "Now this thing which we're gonna call Godzilla has awoken and it's making it's way to the antarctic, why? We don't know yet, it is theorized that it has enough firepower to melt all of Antartica."

Then everyone in the room hear a door burst open as they see the Guardians of the Galaxy enter the room.

StarLord: "No penguin is dying on my watch!"

Drax: "What's a penguin?"

Starlord: "It's a flightless bird that is black and white and can swim in cold water, and they're adorable!"

Drax: "What does this creature have against penguins?"

Rocket: "If you ask me this giant lizard monster is basically the biggest douchebag on the planet."

Nebula: "More like the 2nd biggest."

Rocket: "Who's number one?"

Groot: "I am Groot."

Rocket: "Hey!"

Tony: "Anyways, do we need everyone?"

Nick: "And when you say everyone, you mean everyone."

We then see Carol Danvers enter the room and turn to everyone.

Drax: "Are you gonna help us save the penguins?"

Carol: "What?"

Rocket: "Drax, I'm pretty sure saving the planet means we're saving penguins."

Nick: "Anyways, we'll get to Antartica first before Godzilla."

We then see a montage of the Avengers and the Guardians of the Galaxy getting ready face off against Godzilla. We then see the Milano and a quinjet heading to the Antarctic where they see T'Challa and the warriors of Wakanda getting ready for battle. We then see the Avengers and the Guardians of the Galaxy ready for battle.

Clint: "Should we make him as big as Hulk so it would be a fair fight?"

Scott: "Yeah that's a good idea."*pulls out a red disc*"Just say the word and I'll throw it."

Everyone then see the dorsal plates coming from the waters of the Antarctic. They dive down as they see Godzilla come out of the water and roars at everyone. We then see Scott throw the red disc and shrink Godzilla to the same height as Hulk.

Hulk: "Giant lizard not giant anymore."

We then see Godzilla fire his Atomic Breath and wipe out most of the Wakanda forces with a single shot. We then see Drax pull out his daggers and he's ready to fight.

Drax: "I won't let you hurt my friends or the penguins as long as I live!"

Drax then start screaming and jump onto Godzilla and start stabbing Godzilla. We then see everyone start attacking as Godzilla use his mouth to grab Drax by the leg and throw him at Bucky and StarLord and then use his tail to swipe at Steve and Natasha at the same time. We then see Peter use his webs to shut Godzilla's mouth as he then swing the webcrawler at both Tony and Rhodes to knock them down. Godzilla then get the webs off of his mouth and then fired his Atomic Breath at everyone as we then see Hulk coming in and the punch Godzilla in the face that stunned Godzilla for a small amount of time as Thor then use Mjolnir and Stormbreaker to shoot lightning at Godzilla. Godzilla then absorbed the lightning since this is naturally made lightning and not man made electricity as Godzilla then use his Atomic Breath on Hulk as Hulk then use his hand to block the attack and get close enough to attack the King of all Monsters. Godzilla was about to fire his Atomic Breath again but the attack was interrupted by an uppercut to the lower jaw. Hulk then use his tail to launch Hulk away from Godzilla as Godzilla then stomps his foot on Hulk's chest and then roars at Hulk as Hulk roars back. We then see Carol flies head first at Godzilla and knock him out as everyone else get back on their feet and they were exhausted from the battle.

Rocket: "Man, that is one heck of a super lizard."

Drax: "Yes! We saved the penguins!"

We then see a portal being made by the hands of the Sorcerer Supreme himself, Dr. Strange.

Dr. Strange: "I guess I arrived too late."

T'Challa: "What brings you here Strange?"

Dr. Strange: "Godzilla is not the danger, I've seen a prophecy that he's our defender against the beast known as Ghidorah."

Thor: "What does it look like?"

Friday: *from within Tony's suit*"Boss, something entered Earth's atmosphere!"

Everyone then turn to see a 3 headed dragon landed onto the ground of the Antarctic Circle. The dragon then roar and shoot lightning out of it's wings as Godzilla then wakes up and sees his foe. Dr. Strange then use his magic to communicate with Godzilla.

Dr. Strange: "This is merely an misunderstanding, please forgive us."*to Scott*"Get him back to normal size."

Scott: "On it, stand back guys."

Everyone stand clear from Godzilla as Scott used a blue disc to get Godzilla back to normal size. We then see the Avengers and Guardians of the Galaxy get together and team up with Godzilla to fight King Ghidordah. We then see the Avengers fight off the 3 headed dragon as King Ghidorah use it's gravity beams to try to hit the Avengers, however due to their small size they're hard to hit. We then see Godzilla whack Ghidorah with his tail as Hulk then land on the middle head and use his strength to rip off the middle head. Ghidorah then use it's massive wings to make a powerful Gust of wind to blow away the Avengers and Godzilla as we see Drax being flying around and he sees a penguin being flown away by the winds as he then catches it and use his dagger hold his ground.

Drax: "Don't worry penguin, I'll protect you!"

We then see King Ghidorah fly into the air and leave the area. We then see Godzilla then give chase to the 3 headed dragon as everyone got back on their feet. Drax then let goes of the penguin as then waddles away and then dives into a hole into the water.

Drax: "Your welcome penguin."

Dr. Strange: "We need to get back to the Sanctum Sanctorum, I'll explain everything there."

Dr. Strange then makes a portal that leads back to the Sanctum Sanctorum in New York as everyone heads into the portal where they meet Dr. Strange's friend and fellow sorcerer Wong.

Wong: "Welcome everyone."

Rocket: "Nice digs, pretty rustic."

Vision: "It is a wonderful place to stay."

Dr. Strange: "Alright, let me explain about Godizilla and other like him."

Dr. Strange then makes a projection with his magic and it shows the Avengers and the Guardians of the Galaxy a series of images that look like giant monsters including Godzilla.

Dr. Strange: "For many years since the dawn of mankind, there is a realm within our world where they come from. These creatures are called titans and they come from a realm called Hollow Earth." 

Wong: "The creatures came to our world during it's infancy and bring live to our world, and Godzilla is the alpha of all of them while Ghidorah is an invasive species that has the power to control them to make our planet his own planet."

Rocket: "So what you're is that this 3 headed freaks how is a douchebag that is telling everyone what to do to make their home his home?"

Dr. Strange: "Yes."

Scott: "Okay, so how do we know that all of those things will be awake?"

Everyone then hears the call from King Ghidorah as both Dr. Strange and Wong turn to the others.

Wong: "That will wake them up."

Meanwhile, at the helicarrier, we see Nick Fury looking at all the locations of new reports of all the titans from all over the globe.

Nick: "Will anyone get me the Avengers on the coms right now, we have a worldwide crisis on our hands!"

Random guy: "Yes sir!"

Once communication was established to the Avengers, Nick then sees a giant butterfly flown by, who was Mothra in her adult form.

Nick: "What's going on at your end cause I just saw a bug that has wings wide enough to cover half of the Helicarrier!?"

Steve: *over the coms*"It's a monster called King Ghidorah, we got informed by Dr. Strange that Godzilla is one of many creatures called titans and Ghidorah is gonna use them to make our planet his."

Nick: "Well find a way to stop this thing right now!"

Steve: *over the coms*"We'll come up something."

Back to the Avengers.

Here we see the Avengers at Wakanda with Shuri, Tony, Rocket, Peter, and Bruce analyzing the sound waves from Ghidorah and Godzilla.

Rocket: "Well there's more to these screams than just a wake up call."

Tony: "Yeah they are a method of communication between the alpha titan and normal titan."

Shuri: "We need a device that replicates these alpha waves."

Peter: "So we can herd them to a different place without a human population?"

Bruce: "That's pretty much the plan."

Gamora: "So what are the rest of us are gonna do?"

Tony: "For starters, stop King Ghidorah and his army and help Godzilla."

T'Challa: "Wakanda will try to control the titans in Africa and Asia."

Starlord: "Dibs on Australia!"

Steve: "Half of us will go to Europe while the other half will cover both Americas."

Rocket: "We'll catch up with you guys once the device is ready."

Vision: "Strange, if you please?"

Dr. Strange: "Alright I'm on it."

We then see Dr. Strange make multiple portals that lead to certain parts of the world as the Avengers and the Guardians of the Galaxy head into them. We then see a montage of the geniuses working on the device that can control the titans at the same time see. Another montage of the Avengers and Guardians of the Galaxy doing the best they can to keep the titans from causing any more damage to the world. We then see Starlord contacting Rocket while dog fighting Rodan. 

Starlord: "Rocket! We need that device now!"

Rocket: *over the coms*"We're working on it!"

Back to the geniuses in the lab. We see Bruce finished up on the device and turns to everyone.

Bruce: "It's done!"

Tony: "Friday, get every single speaker all over the globe activated. Time for a global broadcast!"

Friday: "On it boss!"

Tony: "Hope this works!"

Tony put the device to a microphone and activate the device to pacify all the titans across the globe with some exceptions of Godzilla, Rodan, Ghidorah, and Mothra as the geniuses saw it happened on the monitor.

Peter: "Um Mr. Stark, if the device can make alpha waves, what will happen if alpha titans hear it?"

They then hear a loud stomp as the whole room shakes from the stomp happening. They then see a wall being pulled off by a large primate alpha titan known as King Kong. 

We then see Rocket put on a Aero-rig and Tony put on his suit to carry the others out of the room with the device at hand. Later, we see King Ghidorah and Godzilla come into Wakanda as King Kong sees the 3 headed beast and engages the beast. We then see Mothra comes in as Rodan charge in on her and hold her against a large tower in Wakanda and burn most of the wings off as she then stab Rodan and stun him for a while. We then see Kong grab one of the heads and rip it off. We then see one of the heads grab Kong by the foot and throw him at Godzilla. We then see the Avengers arrived just in time to attack King Ghidorah with everything they got as the 3 headed monster then use it's electric power to knock them all down from the sky. We then see Kong get up and charge head first at Ghidorah only for him being knocked to the side and launched to a mountain. Godzilla was knocked unconscious and his battle with the Avengers worn him out as Mothra tries to get him back up. King Ghidorah turns to see Mothra as she then flies even though her wings are a burnt and sacrifices herself to save Godzilla as King Ghidorah destroys her. Godzilla then absorbs the energy from Mothra as Ghidorah attempted to absorb the energy we see Hulk jump onto one of the heads and start punching while both Dr. Strange and Carol then use their powers to distract the heads as Kong then grabs his axe and then hits Ghidorah from behind and then pulls it off and then hold him back with all of his might as Godzilla then stands up in his burning form. Kong then quickly gets away from the area as Tony sees Godzilla in his burning form.

Tony: "Uh guys, we need to evacuate the area he's about to blow!"

We then see all the citizens of Wakenda leave the city as fast as they can as Godzilla then unleash nuclear pulses that destroys King Ghidorah and reduce him to ash as Wakanda was reduce to ash from the pulses. We then see Godzilla holding onto one of Ghidorah's heads and then use his  Atomic Breath to destroy it. We then see other titans from other parts of the world gather around Godzilla including Rodan as they then bow down to their true King of the Monsters as Godzilla then roars in victory as the Avengers and the Guardians of the Galaxy then see it happening.

Groot: "I am Groot."

Rocket: "Yeah, at least he's on our side."

Samuel: "Where do we even put these guys?"

???: "We found a good place for them."

Everyone then turn to Nick.

Nick: "Well, they have to go somewhere right? And I know just the place, we call it Monster Island, an entire island filled with the biggest freak shows on or off of Earth. I believe it's a good place for them."

Several months later, we see all the titans on the remote island called Monster Island as we see S.H.E.I.L.D. forces surrounding the island, making sure that no titan escapes.
