Hey Readers! This story is gonna take place in season 2, after episode 1. I've been wanting to do a Donnie x OC story for a long time now, so I'm glad I'm finally doing it! My OC is inspired by Sombra from Overwatch, on how good she is at being a hacker, and manipulating people. Also I'm going to be a little mean on April O'Neil. I know a lot of you are Donnie x April fans, and I am one of them. But I can't really forgive her after what she did in season 4 episode 22.

Also I try and catch all my spelling errors, so please forgive me, if I missed some.

Anyway, hope you enjoy!

Donnie had shut himself in his lab, hard at work for hours, with no sleep. the tech-turtle groaned from tiredness, bags were forming under his eyes. He and his brothers had been out all night finding mutagen tanks. So far they only had found four. He couldn't sleep, he didn't have time to, he had to figure out what to do about April's dad. He needed to make a cure, it was his fault Kirby O'Neil got mutated in the first place. Well technically, it was all their fault, but he took it harder. April now hatted them, she hatted him. "I never want to see your faces, EVER again!" Donnie sighed, looking up on his wall, where he kept picture of April and himself. He felt a pain in his chest. The turtle looked at his phone, wondering in he should try and text April, to ask if she was okay. But the words she said to him, pulled at his heart. He really messed up. "What's the point..." he sighed, going back to his work.

Just then his phone goes off. Panicking he quickly grabs it, fingers slipping, almost dropping it. Maybe it was April! But it was from some unknown caller. Probably someone got a wrong number.

Donnie sighed in disappointment. He was about to reply with "you have the wrong number." When he saw the text.

UNKNOWN -Is this Donatello Hamato?-

Donnie starred at his phone, his eyes wide. Who is this? Only April knows about the turtles having phones. Unless the Foot clan got a hold of her again! Of maybe it was the KRAANG?! The person texted again.

UNKNOWN -Guessing by how slow you are to react, I'm going to say yes- ;)

Donnie told himself to remain calm. He replied back. DONNIE -Do I know you?-

Very quickly they replied back. UNKNOWN -No-

Donnie raised his eye.

UNKNOWN -But I know you. And your brothers-

Immediately he was send with photos of himself and his brothers. The first time they fought the KRAANG when they went to the surface. The time they met Baxter Stockman, and their first fight with the Shredder. They were taken very well, and surprisingly up close, to make out their faces.

UNKNOWN -You know for ninjas, you're not very stealthy ;P-

Donnie began to panic, shaking his phone. Who was this person, how did they take these? Was he and his brothers being watched the hole time?!

UNKNOWN -You're the purple one, right?- they sent another picture of just him. It was well taken, he was holding his bo-staff and he could see his gap tooth. What shocked Donnie the most was that it was taken the other night, when he and his brothers were fighting the KRAANG. When the mutagen fell out of the ship, scattering all over the city.

DONNIE -You were there?! You were watching us?! THE HOLE TIME?!-

UNKNOWN -I wasn't there, per-say. But I definitely saw everything. It was quite a show XD -

Donnie gritted his teeth. Now this person was messing with him. DONNIE -Ok, enough playing! Who are you?! How do you know about us?!-

UNKNOWN -(◣_◢) Ok first! Threatening something who has photos, videos and information about you, isn't very smart. Aren't you supposed to be the brainiac of the group?-

Donnie frozen. They were right, this person had photos of him, and knew his name. If they wanted they could post it up online. His phone buzzed again.

UNKNOWN -And second, don't you think you have enough problems to worry about? Your red-headed friend who's dad turned into a bat.- they sent a video of how Kirby O'Neil mutated, trying to save April.

Donnie watched with horror. The fear in April's eyes, just made him regret that it ever happened. How did this person take this? They replied again.

UNKNOWN -Also, what about out those tanks filled with glowing green ooze? Mutagen, was it called? I think that's more concerning right now. Don't want a cat to drink it. LOL-

Donnie replied back. DONNIE -This isn't a laughing matter! Do you have any idea of what could happen if someone of something touches it?!-

UNKNOWN -(ಠ_ಠ) Uhh, I just sent you a video of a man become a legit mothman. I know what this stuff can do. Conveniently, I have collected 8 of them (~˘▾˘)~-

Donnie blinked at the photo he was sent. eight mutagen canisters, all tucked in the corner in a dark room.

DONNIE -Ok, I'll only ask this again. And I'll be 'polite'. Who are you? And what do you want with my family?-

Donnie waited, worry on what the person might say.

UNKNOWN -Nothing ╮ (. ❛ ᴗ ❛.) ╭ -

DONNIE -...what?-

UNKNOWN -To be honest with you, I wanted to see if I could contact you myself. I didn't think it would work, or you would reply back to me. I'm impressed with myself! (〃^∇^)ﾉ -

DONNIE -then how-

UNKNOWN -I want to play a game! (─‿‿─)-

Donnie blinked, that came out of nowhere. DONNIE -What game?-

UNKNOWN -listen, you're the smartest one it the group. I wouldn't try to contact your other brothers, because they won't be as fun as you.-

Donnie raised a eye again.

UNKNOWN -Here's the deal, I'm pretty good at what I do.- they sent more pictures -I'm also very good a hacking. It's like in my DNA. I can help you get information from any big corporate company in the City. Hell, the world. And information on any person.-

They sent a picture of April's school ID, which made Donnie shiver. He felt uncomfortable.

UNKNOWN -With someone like me on your side, I can be your inside guy. The KRAANG, the Foot Clan, I could watch their every move, just like I did with you. I could even help collect canisters in the day time, when you can't come up to the surface.-

Donnie thought about this, it could really help him and his brothers. But could he really trust this complete stranger, who knows everything about them? Was it even safe?

UNKNOWN -But of course, I don't do this without getting paid-

Of course. Donnie frowned, he knew they wouldn't do this without getting something in return. DONNIE -I don't have money. If you've been watching me you should know-

UNKNOWN -Not THAT kind of paid, I mean alien tech. KRAANG tech to be persist-

DONNIE -What?-

UNKNOWN -I want more information about the KRAANG, and the mutants around the city. Excluding you and your family. don't worry I'm not a creep wanted to dissect you. I want to see how much information I can collect-

-And as for the game. I want you to find out who I am. If we work together I'll give you little clues to figure it out. I did my research on you, it's only far. ( ಠ◡ಠ ) But here's the rule, you can't tell your brothers, your rat dad, or your red-headed girlfriend about me. If you do, I'll post all this photos and videos to the public-

Donnie swallowed. He was playing a deck, and this person had all the good cards. Should he take a risk?

-I'll let you think about it. As for your clues, I'll give to two to start with. You may call me "INFO-Chan" and I'm a girl. (⌐■_■) -

Donnie made a face. Why would this person, who doesn't want to be discovered, give out their gender. He was not believing it. DONNIE -doubt that-

UNKNOWN -Sorry but I can't send you nudes. Those will costs you ;) -

Donnie blushed. I walked in on that, didn't I. Groaning out of tiredness, he needed to finish this up before he passes out from lack of sleep. DONNIE -Can I think this over?-

UNKNOWN -Know worries, think about it. But don't pretend we never contacted. Remember, I still have way more. (¬‿¬) I'll give you three days. And remember what I said, don't tell your family. What you and I have right now, is just for the two of us~ -

-Bye for now~ -

And that's when they ended the call. Donnie sighed out, leaning down over his desk. That was exhausting. glancing back at his phone, it was 3am in the morning. I need to sleep on this. Slowly getting up, he left his lab, and went to his room. Am I doing the right thing? He asked himself. "just for the two of us~". He blushed remembering what she texted. Or at least they had said they were a she. "She" made it sound like they had a special connection, like girlfriend and boyfriend. Donnie felt a headache coming, groaning he climbing into bed. I have only three days to reply back. And I can't tell the others. Maybe...I don't want to tell them.

Inside a small apartment room, sitting in a gamer's chair, in front of five computer screens, was young woman, busy tipping away. She had just finished her conversation with the mutant turtle Donatello, and was quite pleased with it. Sighing out, she stretched her arms over her head. "That was fun, you out did yourself girl!" She complemented herself. But then she frowned. "Doesn't believe I'm a girl. Though to be fair for him, guys do pretend to be woman online all the time." She turned to the corner of her room, where she kept the mutagen tanks, and smirked.

She heard barking from behind. Turning her head, she saw her pet bulldog, Diesel. He barked, with his upper bite smiling at her. The girl spinned her chair around, patting her thighs. "C'mere Diesel! C'mere!" The dog jumped up onto her lap, licking her face. "Good boy!" She giggled, wheeling her chair back at her screens. each one had different information on the turtles, KRAANG, the Foot Clan, including the members and the O'Neils. But she was focusing on the purple banned turtle in the center of her computers. She smirked, petting her dog's head.

"Donatello Hamato. I think this is gonna to be the start of a beautiful relationship..."
