[No one's POV]
Manhattan, New York, a place where good people come and go. Its also home to a paticular teenage boy living in a nice home with his parents..

His name is y/n l/n..(what you look like)

To his family and friends, he's just a normal boy and a good student at Horizon Academy. But what they dont know..that he's a spider-hero named Spider-X. The ongoing ally of Spider-Man and a carefree hero to all. Right now, our hero is walking downtown to Starbucks to meet a friend of his..

Y/n: Ok, let's hope Pete is there..

Y/n entered the cafe. Before stirring down, he went to a cashier, as he spoke.

Cashier: Welcome to Starbucks. How may i help you?

Y/n: I would like one Mocha Frappuccino.(what he's asking)

Cashier: $3.75 please.

Y/n: *hands him the right change*

Cashier: *takes the money and works on his blended drink before coming back* Here you go. Have a good day.

Y/n: Thanks!

Y/n got hos drink and looked around to find him, but a voice spoke out instead..

???: Hiya, Y/n.

Y/n turned to see one of his best friends.. Peter Parker

Y/n: Hey, Peter. *sits down across him* Any reason why you called me here?

Peter: Well, I've been meaning to ask..how did you do it?

Y/n: What do you mean?

Peter: Gwen told me that you added an A.I in your suit. How did you do it?

Y/n: Well..

Flashback..
Y/n is seen working in his lab on something on his computer that can be a benefit with his spider outfit. Multiple wires are attached to the Spiser-mask and corrected to his computer for one thing... An A.I, capable of detecting enemy locations, zoom into them, hear conversations, night vision, thermal vision, X-ray vision, strategic patterns in the bsttle field and other stuff..

Y/n: Let's see..multi-processor is working fine..voice box is installed..type of dialouge..translator and done.

???: Hey, Y/n.

He turns to see another friend and classmate of his..Miles

Y/n: Hey Miles. What's up?

Miles: Just seeing what my friend is up to.

Y/n: Oh. Just finishing the last touches for an A.I I'm working on.

Miles: A.I?

Y/n: Virtual assistant for my suit. Say hello to Miles, Karen.

Miles: Karen?

My computer started glitching to reveal a holographic woman

Karen: Hello, Mister Morales. It's a pleasure to meet you.

Miles: Woah!

Y/n: Surprised?

Miles: Yes! Youre like Tony Stark. Not even Peter can do that yet.

Peter: *walks from outta nowhere* Can't do what?

Miles: Y/n here installed an A.I system into his suit.

Karen: Hello, Mr. Parker. How are you this evening?

Peter: Umm..just fine.

Y/n: Alright. Karen, download your mainframe into the spider suit.

Karen: As you wish, y/n.

Static electricity surged from the computer into the mask for a few seconds before the eyes flashed, signaling that it's done.

Y/n: Sweet. Lets see if it worked.

Y/n grabbed his mask and put it on and looked to see a hud on his sight. Peter and Miles can't see it

Y/n: Nice.

Peter: What else can she do?

Y/n: Night vision, heads-up display embedded in the eye lenses, allowing me to access a personal database and review information i may have overlooked previously, or to research further into people or events I've previously didn't encounter yet

Miles: Jealous.

Peter: Now i need to update my suit more..

Y/n: I wish you luck on that...

End of flashback..

Peter: Still can't believe you now hand an A.I

Y/n: Yep. In fact, ill cheek up on her.

Y/n pulls out some hi-tech glasses to communicate with Karen..

Peter: What's that?

Y/n: Glasses communicator for me to speak with Karen. It's similar to my spider mask. I made one for you and miles too*gives Peter a copy and puts his on* Hey Karen. Any crime activity in Manhattan today?

Karen: Checking right now..*scans the worldwide web in Manhattan*
There's some unknown bulky creature wrecking havoc on a nearby building.

Peter: Dark creature? Can you describe it for us?

Karen: Running a close scan.. the figure appears to be over 8 feet high, large rows of teeth, and a white spider symbol. I believe out is some kind of symbiote. I'll send you a image.

The image appeared and they have what karen was talking about..

Y/n: Symbiote..wait! Peter, i thought the V2D2 was disposed of?

Peter: It was given to Tony stark a few weeks ago.

Y/n: Someone must've tempered with it.

Peter: What are we gonna do?

Y/n: Kick it's ass, that's what.

Peter: Sweet. Let's suit up. I'll get miles and tell him about venom.

Y/n: Alright. Let's move.

The two boys got up and headed to horizon to gear up.

Y/n: I hope Venom is ready for a world of pain.

[In a different country]
in Paris, France, a young teen is seen wearing a red skintight bodysuit covered in black spots and with a black collar. On her face is a red mask with five black spots that are in a symmetrical design, and the waterlines of her eyes are colored black. This is one of France's heros: Miraculous Ladybug..

Eariler, she had recently found an ancient book of great importance. She didn't quite understand it herself, but she knew whatever information lay hidden in its pages was crucial to the secrets of the Miraculouses.

As she continued to swing herself between chimneys and high roofs, she sighed. Ladybug had only obtained the book because she stole the book from a boy named Adrien Agreste, the boy she had a dizzying crush on. Well, Lila stole it, then threw it in a trash can, but Ladybug was the one to scavenge it. The point was, she hadn't given it back to him and that made her as good as a thief. She reminded herself that her mission was more important than Adrien fretting about a lost book. This was about keeping Paris safe. At least, that's what her Kwami Tikki said and Ladybug was inclined to trust her no matter what.

Ladybug stopped on a nearby roof and then looked down at the GPS on her yo-yo. Tikki had marked a blinking red dot on the map near the south end of Paris. The destination was just a few swings away now. She lunged forward and let her yo-yo wrap around another chimney. In a matter of seconds, she landed in front of an old building. It looked like an abandoned apartment building, but Ladybug sensed a strange energy coming from it. She scanned the building for an entrance and found a broken window on the north wall she good jump through. She used her yo-yo to knock down the remaining shards of broken glass and then jumped in.

The inside was just as wrecked as the outside. Ladybug assumed she was in an old hotel now that she got a proper look inside. There were rusted bellhops and a dusty front counter that had stacks of molted, forgotten books behind it. Ladybug wondered if they were customer logs. The room, the lobby most likely, was probably really grand at one point. There was evidence of huge chandeliers decorating the ceiling and the floor was covered by a moth eaten carpet that was surely lush in its first life time. It seemed like the hotel had a Chinese theme as there were certain accents scattered around the room that reminded her of her mother's own knick knacks and charms. There were once gold lions and punctured lanterns with Chinese characters on them. There was furniture every where, but they were covered by greying sheets with moth holes in them and the entire interior seemed to have a thick coat of dust over it. Streaks of sunlight came in through boarded up windows and from certain angles, Ladybug saw dust particles gently drifting in and out of the beams of light.

It was an eerie place and she wouldn't have been surprised if it was haunted, but she also felt an odd calm feeling. Time seemed to stop here. It was quiet. Peaceful.

After taking another look around the old room, Ladybug released her transformation and became her normal civillan self..Marionette

Her earrings turned black and a small ladybug-like thing appeared in her hands..

Tikki: Ah-choo!

Marinette: Tikki?

Tikki: *wipes a paw across her nose* Marinette, there's so much dust"

Marinette: This is where the Great Guardian lives?

Tikki: Yes! I can feel his presence. I sure hope his room is cleaner though

She flew in front of Marinette and beckoned her to follow. Marinette obeyed and was led to a grand staircase that started wide at the bottom and narrowed at the top. It angled in a spiral shape and Marinette marveled at what a beautiful hotel it must have been before.

Marinette followed Tikki down a hall way that looked like it was brand new with expensive wallpaper and lights lining the walls. Tikki stopped in front of a door on the right.

Tikki: This is it!

Marionette: Ok..

She was being ridiculous. She took a deep breath and opened the door.

An elder Chinese man sat on a futon in front of her. He looked up and smiled.

Old man: Hello, Ladybug.

Marionette: Monsieur, we've met before haven't we? You healed Tikki that one time

Old man: That is correct.

Tikki: Marionette, show him the book.

Marionette: Oh..right. tikki told me that you may know something about this..

She then took out a book with a weird pattern..

The old man's eyes grew wide as they found the book. He looked at yhe two. Marinette gave it to him and he stared at it like it might disappear at any moment.

Old man: Tikki, where did you find this?

Tikki and Marinette relayed the whole story to him. How Adrien Agreste had been holding it, how Lila, or Volpina, took it, and how they took it from her. The old man listened while stroking his beard, absorbing every word with careful consideration.

Old man: Fascinating. Why don't you stay for a while? We have much to discuss.

Marionette nodded and closed his door before sitting in front of him. What they will discuss will soon come to light.
