It happened so quick, no one knew what to think, but several villains from another world passed into ours. The pro heroes thought they were like any other villains; only they weren't! They could take down several heroes easily and still have the power to do more, and what more they easily took down the League of Villains and their benefactor. Several days after they had shown up did the footage of what happened when the first arrived were shown.


"What is this?" All For One asked as he had gathered Shigaraki and his followers to the area they were hiding in after their breakout when a black hole surrounded by green sparks appeared and expanded making a man with dark skin dressed in dark green and brown robes walked in, followed by a man in brown duster which hide a green and yellow suit.

"Is this it?" the duster wearing man said

"It is, but it seems there is some obstacles to overcome" the man in robes said as two more figures stepped out, one in a outfit looking like a heroes' out only black with a target on his forehead and the other was a man wearing armour with a green tunic and hood cape on top.

"Who are you?" Shigaraki asked before they were all forced onto their knees.

"Bow in the presence of DOOM!" the armoured man said "Well done Mordo"

"I aim to please Dr Doom" Mordo bowed.

"So, what now?" the man in the duster said

"Now we kill you!" Shigaraki said trying to move his hand

"So you are villains, impressive. I shall like to add your power to my own" All-For One cockily smirked. Doom then turned to Mordo, who nodded then held up two fingers on his hand and pointed with two on the other hand making a portal behind him, which showed black, suddenly the feeling of being pulled in was felt. Dr Doom then threw up a green field of energy stopping the feeling happening to everyone outside of the field

"You think I wouldn't have planned to take down the biggest threat?" Doom asked "I do hope you enjoy your new home...the core of a black hole" he declared as All-For-One was sucked in and seemingly crushed to dust.

"NO MASTER!" Shigaraki shouted as he reached out for Doctor Doom, only to have a small portal, big enough for his hand to fit through to touch something grey, then he felt unbearable yet familiar pain surge through his body

"NO SHIGARAKI!" Spinner shouted going for his knives .

"I don't think so he man dressed in black said before he drew out shuriken and threw them into Spinner, one in each lung, one in his throat and one in his heart, causing the mutant to fall over dead "That was fun" he snidely

"NO SPINNER!" Twice cried out as he made five duplicates.

"Oh, you can duplicate too" the man in the duster said "Nice to meet you I'm Multiple Man" he laughed making twice the amount as Twice, and each one defeated the Twice Duplicates.

"You bastards!" Twice snapped before he felt some Multiple man duplicates grabbing his arms and holding him in place before the real Multiple Man walked up and snapped Twice's neck killing him. The last two members saw the and tried to flee, Dabi throwing up a wall of blue flames.

"Let's go!" Dabi shouted grabbing Toga's hand and getting out of there.

"Leave them" Dr Doom snorted as he approached the stone throne.

"What should we do now?" Multiple man asked

"Simple, there is a villa that is run by their forces, I want you to go there with Mordo and Bullseye, clear them all out and bring the others to this world. For soon we will rule this world" Doom declared

"Of course" they all bowed and left through a portal Mordo made.

"So begins the Reign of Doom" Doom declared.


Once that video surface the amount of fear in the air increased. It was clear that these guys weren't playing around as word got out of the Meta Liberation Army, which measured in the amount of thousands of members were taken down by 45 of these new otherworldly supervillains. After that Japan was defenceless. Our Pro Heroes were nothing to them ,almost as if they were pretending to be heroes. Soon the pro heroes gave up and started to qui, reducing the amount of hope we all had. Soon The pro heroes started to act like a resistance against these villains; but they were beaten most of the time. Mount Lady, Death Fist, Kamui Woods and Edgeshot were taken down by a group who were named after snakes. Endeavour was nearly frozen to death by one named Blizzard, the Wild-Wild Pussycats were almost killed by one named Sabertooth. Needless to say whoever this Dr Doom was and his forces they were going to take over Japan easily. Things were so bad they turned the Hero academies into secured shelters from these villains attacked, but they still had to worried. Shinketsu had fallen a week after it had been turned into a security shelter as the one called Mordo opened a portal allowing several villains into the school, the students were battered away like playthings by an angry toddler. What was once an age of heroes was quickly becoming an age of villainy. Only what we didn't know was something was brewing on their world. What none of us thought of was: if they were the villains from their world, then that must mean there were heroes as well.


"Any luck finding Doom?" a dark skinned man in a long black trench coat with an eye patch over one eye asked

"Negative Director Fury sir, but we have a list of 48 other missing villains" his second in command said

"gee thanks Hill, Coulson?" he asked turning to a man approaching him, "Tell me you got good news" Fury said

"Yes sir Director Fury sir, the UItimate Alliance Protocol is in full effect, we've asked members of Avengers, X-Men, Defenders, Thunderbolts, agents of ATLAS, the Fantastic Four and even a couple of the Guardians of the Galaxy to join it" Coulson said

"Good, which Helicarrier are they using?" Fury asked

"They've gotten down to either the Bellerophon, the Theta or the Chimera" Coulson said.

"Good choices" Fury said

"Thank you sir" Coulson smiled

"Sir, are we really sure about this?" Hill asked

"I do" Fury nodded

"We have do, we don't know what is going on in that world Doom and the other missing villains went to" Coulson said

"That is why I'm declaring the use of Ultimate Alliance protocol" Fury said

"I couldn't agree more sir" a new voice said as a man wearing a red blue and white coloured uniform walked in, a shield on his back

"That it is Steve, but question is can we follow them?" Fury asked

"I'm sure they can" Steve said. "So the Ultimate Alliance protocol, do you have a list?" Steve asked

"I sure do" Fury said

"Here you are sir" Coulson said as he handed him a list. Steve read it and smiled

"Some familiar faces on there, and all of them look strong enough to deal with whatever Doom's got going on over there" he said

"With Captain America leading them, I'm have no doubt" Fury said before a man wearing what appeared to be robes walked in.

"And of course with my help we'll no doubt find out where they are" The man said

"Dr Strange" Captain America said

"Captain" Strange nodded back. "I've found them" he said

"What where?" Fury said.


"I found them on another world of the Multiverse" Strange said as he used a magical map of the multiverse to show the gathered heroes where Dr Doom and the villains had

"So how do we get there?" Fury asked

"And who did he go with?" Captain America asked

"Oh trust me, he went with a whole lot of nasties" Hill said as images of all 49 villains were showed on a screen behind Dr Strange

"That's not good" a voice in the crowd said

"Agree, but I checked this world just quickly, and don't worry I didn't use Dream Walking or anything like that, I discovered something, those without powers are the minority, 82% of the world has some sort of super powers, which they have dubbed quirks." Dr Strange explained

"Cute" Fury snorted

"Yes, but there Heroes are a professions, they have to be licensed to be a hero" Dr Strange continued

"Kind of like the Sokovia Accords before they were retracted" Hill said

"And that Superhuman Civil War happened" Captain America frowned.

"I agree" another voice said.

"Anyway, I can get us there through a portal. After that we don't know what is going to be waiting for us" Strange said

"Understood, Coulson can you read out, who we have from what team?" Fury asked.

"Yes Sir" Coulson said as he took the stage


"As you know, we activated the Ultimate Alliance Protocol for this, which means that we have several members from several teams here presents and working together." Coulson said "Now I'll inform you of who is in this ultimate alliance" he said as he activated a screen with various squared "First up and no surprise we have representing the Avengers: Captain America, Quicksilver, War Machine, Capt Marvel, Iron Man, Antman, Scarlet Witch, Hawkeye, Dr Strange, Falcon, Hawkeye, Black Panther, Black Widow, Wasp, Thor, Hulk and surprisingly Blade" Coulson said as the screens showed the Avengers members.

"Trust me, I'm just as surprised" Blade said.

"Next from the X-Men we have Havok, Emma Frost, Bishop, Shadowcat, Phoenix, Psylocke, Gambit, Wolverine, Deadpool and Beast" Coulson then said

"I'm an X-Man" Deadpool said surprised making Wolverine groan

"Next up from the Defenders we have Elektra, Luke Cage, Daredevil and the Iron Fist" Coulson said

"Happy to help" Daredevil said

"Yeah we'll bring them down" Luke Cage declared

"Next up we have The Thing, Mr Fantastic, Invisible Woman and the Human Torch better known as the Fantastic 4" he nodded

"Good thing they're coming with us" Dr Strange said

"Yeah" Iron Man nodded

"Now we've got some of the Thunderbolts namely Songbird, Red Guardian, US Agent, Ghost Rider and the Punisher" Coulson read off, making Black Widow groan and mutter something in Russian.

"This going to be okay Nat?" Captain America asked

"Hope so" Black Widow sighed

"Next up from the Guardians of the Galaxy we have Drax and Star Lord" Coulson smiled

"Why those two?" Havok asked

"The rest must be dealing with something major" Captain Marvel shrugged

"Then we have two Agents of ATLAS: Aero and Luna Snow" Coulson smiled

"I guess the others are staying here as backup" the Thing said

"And to finish it off: the Spider-society: Spider-Man, Black Cat, Ghost Spider, Scarlet Spider and Agent Venom"

"The Spider Society?" Ghost Spider asked

"You want to be called the Web Warriors?" Agent venom asked

"No but still" Ghost Spider shook her head as she saw Spider-man looking saddened

"Hey Pete, look after this mission we'll try and find MJ even if we have to crack a certain fishbowl or two" Agent Venom said

"Thanks man" Peter sighed.


"Look Tony we need to talk" Captain America frowned as he lead Tony into a room where Captain Marvel and Ant-Man were waiting for him

"What's wrong?" Ironman asked

"We're taking our biggest hitters with us" Captain Marvel said "heck the majority of the team is our heavy hitters"

"And that means we're leaving the planet vulnerable" Ant-Man said.

"Okay Carol, Hank I know what you mean I knew that too, so I organized a team of our reserve members to be the Avengers while we're away on this other world." Ironman said

"Tony, please tell me you thought about this" Captain Marvel groaned

"I did!" Iron Man exclaimed

"Who did you pick?" Ant-Man asked

"Vision, She-Hulk, Black Knight, Hercules, Photon, Moon Knight, Spider-Woman, Darkhawk and Shang Chi" Ironman told them

"It's a good team" Captain Marvel nodded.

"Indeed it is" Captain America agreed "Alright and if they have any trouble they can fall back and ask for help from the other teams"

"But are we seriously going with some of the Thunderbolts?" Ant-Man asked

"Blame Fury he called them, and he called the less dangerous ones" Ironman said

"One of them is going to be killed Tony" Ant-Man groaned

"Who?" Ironman asked

"Red Guardian, you expect him to act seriously while he's on a team with Nat?" Captain America asked

"Um" was all Ironman could reply with.


"Ah, there you are Natasha" Red Guardian said as he spotted Black Widow sitting by herself

"Hello Alexei" Black Widow sighed

"What no papa?" Red Guardian asked

"That was just for a mission" Black Widow said , but sometimes it felt like it hurt to deny that this man was her father, he was a better father then her actual father, who juts sold her to the red room at a young age. While she was in there she was mentored by Alexei and Melina alongside her sister Yelena. They were given a mission and once it was over the girls were forced back into the Red Room program to become Black Widows under Dreykof's harsh training. Alexei was dumped in a gulag for his part in a mission that went south, only to be recruited by CIA Director Fontaine for her Thunderbolts program. He frowned knowing that The Thunderbolts were the creation of HYDRA leader Baron Helmet Zemo. Eventually he did sign up and was recruited alongside his daughter Yelena. "Even if it did feel real sometimes" she smiled slightly.

"There's that smile I love, so you excited to go to new world?" Alexei asked

"We don't know what will even be over there Alexei; for all we know we're not going to come back" Black Widow said.

"Da, but we are ready to face anything, especially you; for you are Avenger" Red Guardian proudly smiled. "Just being able to say that make me happy, and proud of you Natashsa" he smiled

"I Guess, but try not to get overly emotional" Black Widow said

"I will try, but no promise" Red Guardian smiled

"Good, so how's Yelena?" Black Widow asked

"Stubborn and headstrong, like her sister" he smiled

"Good, at least it's better than being loud and obvious like you. So why were the Thunderbolts recruit; not that I'm not happy for the help but surely Val and Ross wouldn't do it out of the kindness of their heart" Black Widow frowned

"So we can recover rogue thunderbolts" Red Guardian told her

"Who?" Black Widow asked worried

"Moonstone, Ghost, Taskmaster, Whiplash" Red Guardian revealed

"Oh crap" Black Widow panicked

"Indeed, we have been trying to recapture them quietly, but then they join Doom's team and head to this new world" Red Guardian said "So that is why we are here" Red Guardian shrugged making Black Widow let out a Russian curse.


"So which Helicarrier are you going to take?" Fury asked as he and Coulson walked pass several helicarrier docks.

"The latest model, the one which was designed for multiversal travel: The Liberator" Coulson said

Good choice, not only can it travel to the multiverse its also the biggest and consider we have a large team thanks to the ultimate alliance protocol you're going to need the space

"Yeas sir" Coulson said

"Hopefully this mission won't last long, just detain the villains and bring them back, but do try and play nice with the locals Coulson, the last thing we need is another multiverse ticked off at us" Fury said

"I'll keep that in mind sir" Coulson nodded "We took off in 15" Coulson said

"Understood, have fun" Fury said.


15 minutes later all of the heroes were getting on board, Coulson looking over the crew and making sure everything it ready

"So can this take us to them?" Strange asked

"We have a multiversal drive on board, so don't worry but there will be times we'll need your sling ring doctor" Coulson said

"Understood" Strange said "But how are we going to find those who Dr Doom brought to their world, I mean I'm sure they have a master of the mystic arts besides Doom" Strange frowned

"There is one we're worried about, Karl Mordo" Couslon said

"Just had to be him didn't it?" Strange groaned before Coulson got a message saying everyone was on board

"Very well" Coulson said "Starting up the multiversal warp drive" he said

"This better be good." Strange said as a massive blue portal opened for the Liberator to get to the world Dr Doom invaded.


G'day Guys Grizz here, and wow I must say I was not expecting that ending of My hero academia. Anyway I thought of this fic after watching Deadpool and Wolverine as well as reading the fic My Hero Academia-Into the Marvelverse by ShadowNinja77. Now as you guys know I am a major fan of Marvel comics and this fic will have them set in the MHA world, it is also a love letter of sorts with all he different heroes I've picked with inspirations coming from the comics, the movies, the cartoons and some from the Marvel Ultimate Alliance game.

Now before I wrap this up I just want to say a thank you to those at Marvel both now and previous that created the characters we all enjoy today such as Stan Lee, Jack Kirby, Steve Ditko, Don Heck, John Romita Sr, Roy Thomsa, Gill Kane and many more

So until next time I'll catch you on the flipside
