We see Cory, Hooper and Task force Phantom are seen wondering through the sewer trying to find a way out all awhile being alart of the creature that attack and killed Jon.

Some keep an eye on the water and never dare to jump into the water in case it might attack them within the water. They keep on walking through the sewer tunnel looking for a exit.

Cory: This place is like a maze.

Hooper: Yeah a deadly maze. How close are we to the exit?

Y/n: Hopefully not for long.

They keep walking when they suddenly hear some distant roars or growls that echo all around the sewer.

Sam: I think we might be being watched.

Y/n: I think so.

Daniel: Must be that unkillable SCP.

Cory: Who?

Hooper: SCP-692. That thing is impossible to kill and is very deadly.

Cory: Yikes.

Jack: You think it wants pay back from a few months ago?

Y/n: I believe so. Let's keep our guard up and stick together.

They agree as they keep going while also sticking together. Y/n peak around corners and signaling them that the ghost is clear. They exit around the corner and look around to see there is a split.

Zack: Which way?

Before they can figure it out they suddenly heard something on their left and they turn and immediately sees something swimming under the water and heading towards them.

It was a gaint so there is doubt that it is the SCP. Y/n and the rest slowly move back while I gets closer and closer towards them. Soon it suddenly vanishes and they froze in place for a moment. Seconds later there was a large splash and SCP-692 burst out of the water and try to attack them.

Task force Phantom begin to open fire at SCP-692 while moving backwards. Bullets hit SCP-692 but it doesn't hurt him. Daniel fire his grenade launcher which did something as SCP-692 begins to go back.

Y/n: Pull back! Pull back!

They turn and ran off while SCP-692 begins to chase after them. They run through the tunnels of the sewer while SCP-692 is on their tail.

Y/n: We can't lose him! We have to split up!

Cory: Thought you said we need to stick together?!

Y/n: Change of plans! Split!

They all begin to split off to different directions while SCP-692 stop and see them splitting off. He try to decide who to chase snd thne he dive into the water and goes after whoever he picked.

We cut to Y/n running and soon stop and turn back to see that he is no longer being chased. He hopes that the rest will be alright and active a tracker so the rest will find him.

Then he hears voices deep in the tunnel so he investigate the voices. Soon he turn a corner and stop as he peak over and sees skull like soldiers cover in black armor ad they are awaiting orders.

Y/n: (whisper) Who are they?

???: Yes sir. Copy, over and out. (Cut communication) A mobile Task force will be on their way to stop the containment breaches. We need to get out of here along with the information.

They agree as Y/n noticed boxes filled with missing files from the site as the soldiers then head off. Y/n decided to follow however when he turns corner they suddenly disappeared.

He look around seeing nothing and begins to think that whoever the soldiers were, they must be a bugger threat to the world.

Jack: Hey.

He quickly turn and sees Jack as the two came together and Jack ask.

Jack: What happened?

Y/n: Long story but where's everyone else?

Jack: Probably still out there but listen, while I was running I found the exit.

Y/n: Good. Let's meet up with the rest and get out of here.

Daniel: No need.

Then Daniel, Zack and Jack arrived as they came up to them. Soon Hooper turn a corner and rush over to them and now it is just Cory.

Hooper: Hope Cory is alright.

Y/n: He seems to avoid a lot of dangerous SCP so I think he'll make it.

Daniel: Let's hope so.

They stood here for a moment and then suddenly Cory run around the corner and runs towards them while saying.

Cory: Run!

He run pass them which they turn back and see SCP-692 also turning a corner. They immediately run after Cory as Jack takes over and guide them to the exit. After a while od running they run through a tunnel with a exit however its blocked with metal bars.

Hooper: I can't break through!

Daniel: I'm almost out of explosions.

Sam: No point. We'll be killed if this tunnel collapses on top of us.

Cory: Any plans?

Then they hear its roar as SCP-692 is getting close and then Y/n has a idea.

Y/n: You all hide. I know how.

They obey and hide as Y/n draws out his pistol and shoot the lights out. He is now cover in darkness as he stood in the middle of the tunnel and soon SCP-692 appears and turns to Y/n direction and then it spoke.

SCP-692: I do not need to see. I can smell you.

Y/n: Then come at me. I'm not afraid.

SCP-692: How interesting. Too bad I have to kill you.

SCP-692 then charges towards him and was about to ram into him when he quickly leaps out of the way as SCP-692 runs pass and break through the metal bars and giving them a exit.

They exit out to the surface and sees SCP-692 laying unconscious as they all breath a sigh.

Cory: We're free!

Daniel: Thank god. I thought we never gonna get out.

Sam: You said it.

Hooper: That was some adventure.

Y/n: No kidding. Come on.

They walk away from the tunnel and SCP-692 as they made it to a clearing and Y/n pulls out a flare gun and shoots a flare into the sky. Moments later their Avenger flies over head and soon begins to land in front of them.

The drop door begins to open and William was the first to greet them as he came over to them.

William: Well aren't you all lucky. While you all have soke fun I was out here with SKYFIRE bored out of my mind!

Y/n: Good to see you FIREMAN.

William Let's out a small chuckle as the two fist pump. Them the general came out of the Average which they stood at attention.

Y/n: Task Force Phantom reporting.

Hooper: Corporal Hooper reporting.

Cory: Oh and Cory.....reporting.

Male general: At ease soldiers. Task force Phantom I appreciate everything you did during the containment breach.

Y/n: It's our job sir. Although the site was not completely cleared.

Male general: We had the situation under control. Get some rest, you all deserve us. We reassign you to a new site.

Y/n: Yes sir.

They then climb onto the Average and once on Victor is seen on the pilot seat as he look out and called out.

Victor: I knew you all will make it.

Y/n: Indeed. Anything happened while we were inside the site?

Victor: Nothing much. Most of the staff got out just in time before they be killed. There were plans to nuke the site but I convinced them not to.

Daniel: That would have been good to see.

Sam: Yeah not the type to get blown up.

Daniel: I am. (Chuckle)

Sam rolled his eyes as Victor begins to take off. The drop door closes and then Jack noticed 999 which he called out.

Jack: BOSS. We might have a SCP in here.

They spotted 999 as Sam groans a bit.

Sam: Great that thing must have followed us until we got in.

Daniel: So what should we do with it?

Y/n: We'll take him to the new site where they will keep this one contain.

Sam: So we're stuck with that thing.

Y/n: Yep.

Sam: (sigh) Damn it.

999 pured on Sams leg which he groans even more as a few of his team laughed as the Average flies away and leaves the area.

(Present day)

At the interrogation room the agent stops his story and ask.

Male agent: Sorry to interrupt but you haven't told us the incident between your team and the SCP foundation.

Y/n: I'm telling you all we met Cory.

Male agent: Why?

Y/n: Because he's important to the story. Trust me.

Male agent:.....Give me a moment.

He stood up and leaves the room. At the other side of the mirror we see a man watching Y/n when the door open and the agent enter and ask him.

Male agent: Sir should we end the interrogation?

???: No. Let him continue.

Male agent: But sir this will take us forever. Maybe if we talk to the rest we can-

???: He's someone he will give answers to. Besides we need to find proof that one of their site directions is responsible for crimes against humanity and he's our only hope.

The agent sighs and leaves the room. He then return back to the interrogation room ans sat back across of Y/n and then he ask him.

Male agent: Tell me about Cory? Why is he important to the story?

Y/n: Cory is a mysterious person. Disbite his light hearted possibility he has a mysterious past.

Male agent: Did you ask him about his past?

Y/n: One time but he explain he doesn't know who were his parents.

Male agent: Right......Well tell me.....when is it the next time you met Cory again?

Y/n: A few months after we escape both he and Hooper were promoted to be mobile Task force units of the foundation. Their team leader, Tirana were sent out on multiple missions involving capturing SCP creatures. At first seems to be slowly going back to normal but little did we know something big would change our entire mission forever when we were assigned with along side them to capture a SCP.

Male agent: And who is this SCP?

Y/n: SCP 1000.......Bigfoot.
