"There is no way my brother could have two kids already." A man said, working on his latest invention.

He was known as Sean Fenton, the older brother of Jack Fenton. He was well aware of his younger brother was married with his college sweetheart and they both made a name for themselves after discovering Ghosts were real. As much as Sean couldn't believe it, he knew that Jack has every right to have his frame, as long as he matched it. Sadly, Sean could never find a woman he liked, and it was even more shocking when he learns he had a niece and nephew! he saw their images from the paper and wanted to meet them in person, but he couldn't not until he finished his creation.

"Calm down, Sean. Jack is just being himself. No need to get worked up. He's family." Sean told himself.

"FaTHer? Is SoMEtHINg WRonG?"

"No, no, my dear. I was thinking about your cousins. It going to be the first time we both meet then in person." Sean said, looking at a robot head.

"DaNIel aNd JaSmINe, RiGhT? IT WouLD bE NIce To SEe tHEm. It spoke.

"I know, my dear. But I still need to finish your body and your voice chip. Both should be done at the end of the week." Sean said, getting back to work.

The robot head remain quiet as if not disrupt his work. However, her mind was already thinking. She moved her eyes to the picture of her cousins, thinking of how the first meeting might. She kept looking at her cousin, Daniel. There was something about him that made her gears click each time she looked at him. She really hopes to learn much about him and the things they can do together.

"DAniEL..." She said, still looking at the picture.

Three weeks later,

Sean finished the last touches of his robot daughter before uploading the A.I. She was cover in mostly white with golden highlights. The face looked very make like a human and she had long white hair flowing down her back. And even white eyes. Sally Fenton was born at last.

"S.A.L.L.Y? How are you feeling?" Sean asked.

"Systems...100%. Backup...100%. Face scan...Sean Fenton. Hello, Father." She spoke.

"Hello, S.A.L.L.Y." Sean smiles.

She walks off the stand and looks over her body. There were still some metal parts shown, but she looked very much like a human. She even notices her voice chip was fully fixed, making her sound much like a teenager.

"S.A.L.L.Y? Is everything okay?" Sean asked.

"Just double checking." She said before smiling.

"No errors found."

"Good, I think it's time to see my brother again." Sean smiles.

"And Daniel and Jasmine?" Sally asked.

"And them too." Sean smiles.

"I'll get the van ready. You take the time you need to understand your body a bit more." He said, making her nod.

Sean exited the room, sighing. It was along three weeks, and he was starting to wonder if there was something different about his robot daughter. For some reason, she was focusing on Daniel. Sure, she threw in Jasmine a few times, but she spends most of the time taking about his nephew. But why? He shook his head, maybe he shouldn't worry about it.

Sally picked up the picture of her cousin Danny, looking at him thoughtfully. She knew she'll be meeting him in person for the first time and she was aware that not everything matches what she read and heard. For some reason, whenever she thought about her cousins, her mind always was on her cousin Danny. She didn't know why, but she knew she would learn soon. For now, she just has wait until she meets him.

Fenton Works,

"Really?! It's been years! Of course you can visit!"

Danny blinks as he just returned home from school, quickly hiding the Fenton Thermos in his backpack. Both he and Jazz spotted their father talking on the phone as their mother looked confused.

"Mom? What's going on?" Jazz asked.

"It seems that someone from Jack's family has reached out to him." Maddie said as her husband kept chatting.

"Really? You have a daughter?! Congrats! Can't wait to meet her!" Jack cheers.

"Sure, I'll let my family know! See you in a few hours, Sean!" He added, hanging up.

"Who's Sean?" Danny asked.

"My big bro! Unlike me, Sean was more into the fields of robotics. Never did see the idea of it, but some of those robots he made looked awesome! We had a bit of brotherly rival as kids. But it was all in good fun!" Jack said.

"You mention he had a daughter?" Maddie said.

"Yeah, through Sean told me that he had to build her. He tried to get a date so many times, but a lot of women didn't match what he wanted. Sean was always better at getting girls then me. Not sure why he had a hard time finding one." Jack said, confused.

"We have an uncle?" Jazz asked.

"And a robot cousin?" Danny added.

"It been so many years since we last talked. Which was after High School. I did invite him to the wedding, but he never showed. I'm sure he was busy at the time." Jack said.

Danny sighs, he just hopes this wasn't going to turn into another Vlad.

Later,

"You have an uncle?" Sam asked, surprised.

"And robot for a cousin?" Tucker asked.

"That's not as bad as in having a clone for a one." Danny pointed out.

"True." Tucker said.

"My dad mention they will be here in a few hours. So, I'll get a chance to know them when they arrived." Danny said.

"Still, who's your uncle?" Tucker asked.

"Sean Fenton." Danny said, making Tucker freeze.

"SEAN FENTON?!" He shouted, quickly looking his PDA.

He showed Danny an image of a young man wearing a lab coat with shirt under it, he had black hair and blue eyes holding a trophy from a fair he won.

"That's your uncle?" Sam asked, surprised.

"Wow, he almost looks like an order version of me." Danny said, surprised.

"I can't believe you're related to my number one hero!" Tucker said, still shocked.

"And his last name didn't clue you in?" Sam asked, rising an eyebrow.

"How was supposed to know? You know how Danny's father gets when he starts talking." Tucker brought up.

"Point," Sam agreed.

"Well, I'm sure my dad won't mind if I have you over, just try not to get carried away?" Danny said.

"Sure, sure. I got it under control!" Tucker smirks.

And going to end here. Heh, another OC girl story. They are just flowing out, huh? Sorry, can't help it sometimes. Okay, something a bit different. Not only am I using a robot girl, but I'm also making her Danny's cousin. Question, would cousin pairing count as incest too? I know it's mostly using for siblings, but what about other family members?

So, what we have here is Sally Fenton, Danny's robot cousin. Used the cover for a better idea of what she looks like. She was made by Sean Fenton, Jack Fenton's older brother. Sean is kind of upset that Jack not only got married but had kids too. However, he's nothing like Vlad. He's not after Maddie or want his brother kids to be his. However, it seems that Sally is focusing on Danny before they even met. The next chapter will cover the two meeting for the first time, and some old things that most of you will expect.

And you guys can come with what S.A.L.L.Y stands for. I stuck at those.
