Here we see the Pro Heroes heading to a ruined part of the city to find whatever destroyed the area, since this was a field trip Class 1-A and 1-B was being chaperoned by All Might along with other Pro Heroes like Mt. Lady, Mirko, Ryukyu, and Midnight. Here we see the heroes encounter a large entity that looks like an insect-like humanoid.

All Might: "Stop right there villain! Your days of bringing destruction to the city are over because we are here!"

???(Alexei Belitrov): "Please I surrender, do not harm me!"

Midnight: "Huh well that was easier than I thought."

Katsuki: "Grr, I can't believe this!"

Mirko: "It couldn't be that easy right?"

Then helicopters from the SCP Foundation arrived along with Mobile Task Force soldiers surrounding the humanoid.

MTF soldier: "Sir, did he put up a fight?"

All Might: "Actually he surrendered on the spot."

Mt. Lady: "Why would he just surrender? It's like he wanted to be captured."

Tenya: "Hmm, perhaps all of this destruction was not his doing and he's in a different environment. That's what I'm going with based on his reactions."

Later, we see the entity who is now in it's cell and number SCP-2273 as we see you and the heroes in the observation room.

(Y/N): "You found this guy in your city?"

Ochako: "Yeah, what did you come up with (Y/N)?"

(Y/N): "Well he has an appendage that looks like an organic transmitter, open wounds on the shoulder blades and forearms, and scars that are in the shape of military badges from the Soviet Union."

Ochako: "Okay but any reason why he gave up so easily?"

(Y/N): "The medical team examined that he was tired, injured, and malnourished. Once he recovers, I'll talk to him."

After the SCP's recovery, you are in another chamber with a radio as the Pro Heroes Midnight, Mt. Lady, Ryukyu, and Mirko were observing you.

Midnight: "Why do you need a radio for?"

(Y/N): "We need to talk to the guy."

Ryukyu: "Is there anything else we need to know about it?"

(Y/N): " Well from the X-Rays there's a guy inside the suit, just a normal guy in an organic bug suit. He speaks Russian, and I can speak all kinds of languages including dead ones."

Mt. Lady: "Alright let's see what he has to say then."

(Y/N): *speaks into the radio in Russian*"Hello, can you hear me?"

???(Alexei Belitrov): * from the radio in German*"Your accent is atrocious, speak into a language that you understand."

(Y/N): "I guess German is Russian from wherever he's from."*speaks into the radio in German*"Your name is Alexei Belitrov correct?"

While you and Alexei are talking the Pro Heroines are having a hard time understanding what you and Alexei are saying.

Midnight: "Um what are they saying?"

Mt.Lady: "I have no idea, I don't speak Russian or German."

Midnight: " Okay does anyone have a translator on them? Or a German to English dictionary and a Russain to English dictionary?"

Ryukyu: "Nope."

Mirko: "I do but I left it at home."

Back to you and Alexei.

Alexei: *over the radio in German*"Let's quit with the pleasantries. I am a prisoner-of-war and you are my interrogator. You killed my men, tortured me, and left me to die in the wilderness. Have you not done enough?"

(Y/N): *speaking into the radio in German*"I beg your pardon?"

Alexei: *over the radio in German*"You heard me. Don't act like you don't know what was done to me before I was brought here. My men died because I surrendered. I see now that it was a mistake. They should have died like warriors, fighting for the Motherland, not gunned down like animals. I thought I could end the war for them, give them much-deserved peace. Instead, they are dead, likely not even buried but left to rot, and I am here, being interrogated by some skinny in an American Concentration Camp."

Ryukyu: "What do you think they're talking about?"

(Y/N): *speaking into the radio in German*"We're not with the USA."*to the girls in English*"His name is Major Alexei Belitrov, he thinks the world is at war and we killed his men like dogs."

Ryukyu: "Woah what? But we just met this guy. How can he know that we killed his soldiers?"

(Y/N): *pulls out a level one researcher general debrief*"Watch and learn girls."

You then head into Alexei's room and then hand him the debrief as he reads the debrief. You then head back into the room where the girls are as Class 1-A and 1-B joins in as well.

Mina: "So how's the interviews going?"

(Y/N): "Good so far, we learned that he came from a world at war between the USA and Russia armies and he thinks we killed his men."

Mina: "Why would he think that?"

(Y/N): "He's a soldier of war and he thinks we're at war. I'll talk to him."*speaks into the radio in German*"You ready to talk?"

Alexei: *over the radio in German*"I understand now. You... you are not dogs, you are crows."

While you and Alexei talk to each other we see the heroes still confused on what you're both saying.

Pro Heroes and Class 1-A and 1-B: *in their heads*"Dear god what are they saying!?"

(Y/N): *to the pro heros*"Okay in case you were all wondering what we were saying I asked him if he was ready to talk and he came to senses and realized we're not the enemy."

Ochako: "Thank you for clearing that up."

Tsu: *to Momo*"Don't you know what they're saying?"

Momo: *blushes a little*"Well my German is a bit rusty."

(Y/N): "He calls us Crows, it's Red Army Slang for SCP Foundation. In his Earth, the Foundation steals weapons from both sides for containment. I told him that we would bring him home but he and I both know he will stay in a cell for the rest of his life."

Momo: " Isn't that a bit much?"

Katsuki then blows up in rage literally as he then turns to you in anger.

Katsuki: "YOU ABSOLUTE DUMBASS!! YOU HAVE THE MEANS TO GET HIM HOME BUT YOU CAN'T CAUSE THAT WILL BREAK HIM OUT OF JAIL AND GET ON THE FOUNDATION'S BAD SIDE! NO THANKS TO YOU, HIS WORLD WILL THINK HE'S A COWARD AND HE LET HIS FELLOW SOLDIERS DIE FOR NOTHING!!!"

(Y/N): "That is bad if you put it that way."

Katsuki: "OH NO SH#T SHERLOCK! HOW ABOUT YOU GET OFF YOUR ASS AND BUST HIM OUT!!"

(Y/N): "Where would he stay in our world? I know the Foundation is not the best choice of a home, but it's all he got."

Ejiro: "He has a point, Bakubro."

Katsuki: "Ugh, fine! BUT IF YOU DON'T FIND A DECENT HOME BETTER THAN THIS FOR THIS BUG EYED FREAK! I'LL KILL YOU!"

(Y/N): "I'll ask Alexei for more details about the war in his world."*speaks into the radio in German*"Can you explain this war at the best of your ability?"

Alexei: *over the radio in German*"It is the Second Great Patriotic War, the War to End the World. Several years ago, when I was only a child, the Americans launched a nuclear attack against the Motherland and her allies. We retaliated in full force. Very few people were left alive, and much of the surface was rendered unusable for farming, or even just living. That is why I am in this armor. I couldn't survive very long on the surface without it."

(Y/N): *Speaks into the radio in German*"Can you tell me who made your armor?"

Alexei: *over the radio*"It was built for us by the engineers. I don't know how they do it or how they work, but this armor has saved my life more times than I can count, and has been worth the pain it has caused me."

While you two are talking in German, we see the heroes once again unable to understand what you two are saying.

All Might: "What are they saying?"

Tenya: "I would figure out what they're saying if I had my German to English dictionary."

Mina: "Ugh this is so frustrating!"

Katsuki: "WHAT ARE YOU TWO SAYING!?"

(Y/N): "Alexei told me about the war in his world, he calls it the Second Great Patriotic War, the War to End the World. When he was a kid, America attacked them with a nuclear warhead and the Russians retaliate and left the planet's surface uninhabitable. The purpose of his suit is to survive the radiation of the surface, but he doesn't know how the suit works or how it's made. But the people who made it are called the Engineers. His parents volunteered him to be a test subject for the suit and it took many years to grow into it but he felt a lot of pain in the process."

Shoto: "What about the scars?"

(Y/N): "Those were his weapons and supply packs. Also his suit is alive. His men were stationed at a place in America to fight off the Americans until they were ambushed by Americans and he surrendered to them only to have his men killed, they spared him cause he is their leader. Then a flash of light he appeared in a place where there is life everywhere."

Momo: "So his suit is symbiotic?"

(Y/N): "Yep."

Tenya: "These Engineers, who are they?"

(Y/N): "I'll ask."*speaks into the radio in German*"Who are the Engineers?"

Alexei: *over the radio in German* "Crow, do you not have engineers here, in this world? They are very much not like us. They fear the sun and have coats like beasts, but are smarter than any man; skinny or armored; crow, dog, or Soviet Patriot; any man you may ever meet. They are what has made the modern war possible, for both sides."

You and Alexei talk to each other for a while as they still don't understand what you two are saying.

Neito: "How can Class 1-A be worthy heroes if they can't understand what they're saying!"

Mina: "Oh yeah, if you're so smart then tell us what they're saying?"

Neito: "Touche."

Itsuka: "Hey (Y/N), what did you get out of him?"

(Y/N): "Well according to him, we actually have Engineers. We just call them by a different name, SCP-1000 or Bigfoot. Opened up that old wound."

Neito: "Bigfoot? You mean that giant mythical hairy sasquatch?"

(Y/N): "No, no that Bigfoot, there's a lot of those all over the world. Many years ago before we invented the wheel, I was in love with a forest trickster goddess and in return she helps me and humanity takeover Earth, I managed to get their weapons and I wiped out 70% of the Bigfoot species and wipe away the minds of the remaining 30% to reduce them to a mental state that makes them go feral."

Neito: "Um what?"

Mina: "Wait, you made Bigfoot an endangered species out of love!? What is wrong with you?!"

Denkai: "Yeah man! I'm a ladies man and even I know there's a line you shouldn't cross!"

(Y/N): "She made me realize that she told me who would want to love a monster like me. I've been all over the Earth looking for her so I can just kill her."

Mina: "But why?! Why would you almost kill an entire population?! What do you have to gain from that?!"

(Y/N): "I asked myself that question everyday of my life after that. Anyways, he is going through PTSD and the suit is not helping. One of the suit's features is to store and replay memories."

Mina: "So that's why he thought we killed his men. He saw those same memories over and over and couldn't tell what was reality or real."

(Y/N): "He did say he should've died with them."

Mina: "What would happen if we took the suit off of him?"

(Y/N): "How? He grew into it and he can't get out. I'll get Biggie on this."

Later, we see Biggie examining the suit on Alexei as you enter the room.

(Y/N): "Anything?"

Biggie: "Sorry, but I am not familiar with this. I have never seen this kind of technology of my people be so advanced."

(Y/N): "Hmm I see, I guess if he lives with it then he'll die with it."

Mina: " You're kidding right?"

(Y/N): "I'm sorry but what other option do we have?"*to Alexei*"Sorry bud."

Alexei: "Da, it is okay my friend, I will atone to my death."

(Y/N): "Hope you will be okay."

Alexei: "I will."

Later, we see you and the heroes at a restaurant in Beach City and they're having a meal with the Crystal Gems.

All-Might: "Who are these geode themed heroes?"

(Y/N): "They're the Crystal Gems."

Midnight: "Crystal Gems?"

Mt. Lady: "How long have you been heroes?"

Pearl: "You know we've been on Earth longer than you think you know?"

Garnet: "Indeed, we have been here for eons."

Amethyst: "Really? Thought it was like a century or two."

(Y/N): "Yeah I've met them before and fought alongside them."

You then spot a familiar man that you know during your onslaught of SCP-1000. You then walk up to him and grab him by the collar and hold him up in the air.

(Y/N): "Adam!"

Adam: "Oh hey how have you been (Y/N)?"

(Y/N): "I've been through Hell, on multiple occasions."

Amethyst: " Woah dude you know this guy?"

(Y/N): "This is Adam, the First Man, one of the O5 members, a womanizer, and my younger brother."

Pearl: "You have a brother?"

(Y/N): " Unfortunately, yes I do, I'm still peeved because he and the new O5 turned me into a woman!"*To the girls*"No offense to you girls."

Midnight: "None taken actually, in fact I like to see you on your feminine side sometime."

(Y/N): "It wasn't as pleasant as you thought it was. Also-"*punches Adam in the face*

Adam: *after getting punched*"Agh! What was that for?!"

(Y/N): " That was for that little prank you pulled and there's plenty more where that came from!"

Izuku: "Wait you mentioned something about Adam being a womanizer, what do you mean by that?"

(Y/N): "He broke up with Lilith over carrier pigeon. And he left his 3rd wife Eve after Cain killed Abel out of jealousy."

Garnet: "What about his second wife?"

(Y/N): "You do not want to know, it wasn't pretty."

Midnight: "Wait a second, breaking up with someone over carrier pigeon is another way of saying-"*realizes*"Oh my gosh, he broke up with her over text!"

Adam: "Hey I put a smiley face on it, I'm not SCP-106."

???: "ADAM!"

You and the others then see a woman that you know too well.

(Y/N): " Oh no."

Pearl: "Who is she?"

(Y/N): "The First Demon of Hell, Lilith."

Lilith then slaps Adam in the face out of anger.

(Y/N): "Hey Lily what's up?"

Lilith: *sees you and in a sweet tone*"Oh hi (Y/N) it's good to see you, how was your time as a demon?"

(Y/N): "I thought it was nightmare fuel but actually it felt nice to be in your shoes for once."

Lilith: " That's wonderful, say you don't mind if I kill your brother do you? You know, for breaking my heart!"

(Y/N): "Well the O5 needs him, unfortunately. Plus he sent me a rock that turned me into a girl."

Lilith: "That's awful, can I at least beat him up to the point where he can't get up?"

(Y/N): "Hmm yeah that's acceptable. Besides-"*points to the angel in the room*"His new angel girlfriend just might patch him up again, her name is Serafina."

Serafina: " Hi."

Lilith: "Ugh why did it have to be an angel?"

Serafina: "What?"

Lilith: "Listen golden girl I'm gonna save you some trouble, that guy was my boyfriend until he broke up with me over carrier pigeon!"

Serafina: *gasps*"No he wouldn't do that right?"

Lilith: "He would and I still have the note to prove it."*pulls out the break up letter*"See."

Serafina: *reads the letter*"This was written on the 14th of February, which means-"*to Adam*"You broke up with her on Valentine's Day?!?"

Adam: "W-well I-I mean-"

Serafina: *emits heavenly light out of anger*"I don't wanna hear it! I knew there was something off with you! We're through!"

Serafina then flies back to Heaven as the girls turn to Adam.

Pearl: "I can't believe Steven was one of your descendants!"

Garnet: "You're terrible at relationships."

Amethyst: "Yeah you make Hal's breakup with a violet lantern look like a sequel!"

Ejiro then leans towards Katsuki and whispers to him.

Ejiro: "Hey Bakubro, teach this guy some manners."

Bakubro: "Alright."*to Adam*"Hey Adam."

Adam: "What?"

2 seconds later. Here we see Katsuki attacking Adam by using his explosion quirk.

Katsuki: "DIE! BURN HELL ADAM!"

Adam: "AHHHHH!!!"

And 5 hours after that, we see Adam in a hospital bed at the Foundation and his body is in a cast.

(Y/N): "Serves you right."

We then see Castiel fly into the room and turn to you.

Castiel: "Serafina was crying like a woman with a horribly shattered heart like an emotional time bomb, what happened?"

(Y/N): "You know what happened between Lilith and Adam?"

Castiel: "I was not aware of their relationship, why?"

(Y/N): "Adam broke up with Lilith over carrier pigeon."

Castiel: "Is that a precursor to breaking up over text?"

(Y/N): "Yes."

Castiel: "Oh I see well he got what he deserved."

(Y/N): "Agreed."

We then see Lilith appear into the room and turn to you.

Lilith: "Hello (Y/N)."

(Y/N): "Oh hey Lilith what's up?"

Lilith: "Well...since you're the only one who comforted me since Adam broke up with me and we've known each other for a long time, maybe we can have a relationship together?"

(Y/N): "Sure, but aren't you married to Lucifer?"

Lilith: "Oh about that, me and Lucifer aren't together anymore."

(Y/N): "Does Charlie know about this?"

Lilith: "She does, at first she was a bit surprised but she accepted it and she understands."

(Y/N): "Okay I guess we're a thing now."
