Loki's Twin, Tony's Sister

Iron Siblings

"No" Tony once again deadpans his little sister's request.
"Well it looks like we are at an impasse. Actually, instead, you have two choices here too." Rachel smiles, looking up, the couple of inches between Tony's height of 6ft, and her's of 5'9.
"Oh?" Tony raises a brow, a questioning glance at the girl.
"Yep!" She pops the 'p', "You can either help me build it, or I hack Jarvis and build it myself." Her smiles quickly vanishes, and is replaced with a stony look of determination, one that reached the depths of her eyes, a look Tony knew well.
"This is like the fighting we did over school all over again!" Tony groans as Rachel smiles widely, knowing with that sentence Tony gave in. Tony managed to graduate college at the age of 17, a few years later Rachel, at the same college and classes, graduated at 16, but that was just the first school, after that Rachel was able to complete four more years of schools from two different schools in a matter of 2 years, before she went overseas and started extra colleges there. Rachel loves to learn, it's her favorite pass time, she's not a player like Tony, but she does go through books like Tony goes through women. She's gone to colleges for everything imaginable art, mechanics, medical, science, law, dance, fighting, etc. etc.
"Oh and I get a say in the design, I don't want it clunky like yours." Rachel puffs out her chest proudly.
"Fine, Jarvis let's get started on one for Chele." Tony sighs to the A.I. (Artificial Intelligence) butler, the literally runs the whole of the house, and much more for Tony and Rachel. Rachel's phone even has Jarvis programmed into it, something of her invention, and that Tony uses quite often.
"Yes Mr. Stark, and hello again Miss Rachel, you look quite better now that you've seen Mr. Stark." The automatic, British accented voice of Jarvis sounds all around the room. Rachel blushes brightly as Tony raises a brow at her.
"Jarvis!" She says hotly.
"I'm sorry miss, was I not suppose to say anything about it?" Jarvis retorts.
"NO! You most certainly weren't!" She continues pouting and blushing as Tony laughs.

~~*Time Skip 3 Months*~~

"Rachel to your right." A slightly robotic voice sounds out. A small growl echoes over the quiet land and intercom of the suit, followed by a light, yet pissed female voice.
"Yes Tony, I'm not blind." All of a sudden screams of men were heard, then silence.
"Come on, let's get out of here." Tony says to his little sister who was checking on a couple of civilians.
"Kay." The girl bounds over, next to her brother, her footsteps swift and quiet on the dirt of whatever town they were in, in the middle east. Standing next to her brother, the pair's rocket boosters activate and the two take off from the ground. Tony gaining altitude a bit more quickly than Rachel, quickly changed how his body was before shooting off into the sky, a blur of red and gold, with a dark blue and black blur following him.
"How can you move like that?" Tony asks his sister to break the quiet that had taken over the two as they flew.
"Well you know my suit is a lot thinner than yours, and less clunky, as well as tailored exactly to my body. Plus a lot less weapons than yours, and all the lessons I took on how to fight, and dance." Rachel said proudly. It's true, Rachel's suit, which was blue and black, was remarkably thinner than Tony's, but she didn't have exactly all the gadgets that Tony had. In Rachel's suit was knifes, of all kinds, the inside of her arms held compartments that had marble sized grenades (her own invention), her mask, which looked like a panther's head (ears and all) held surround video, and the ears laid down to reveal small, yet powerful, guns. The top of her arms held 4 blades made of single-crystal titanium, like some of Tony's suit, her feet held both springs and boosters to help her jump about and land hard kicks, she also has a tail that is basically an electrical whip, powered by the arc reactor in the middle of the suits chest, Tony insisted putting the reactor in the front, he made it so she could use it as a weapon as well, sending out a beam, much like his own suit. The initial build for the suits, are the metals, single-crystal titanium, and nickel-titanium, or nitinol. Tony's phone ringing in both their ears cut the conversation short.
"Rohdy!" Tony exclaims, but Rachel quickly loses interest as two fighter jets suddenly appear behind the two.
"Uh Ton....." Rachel calls out to her brother.
"Hold on Rohdy." Tony tell his friend and turns to look at Rachel and nods. Rachel, catching her brother's movements, nods back and the two quickly start trying to out maneuver the jets.

~~*Time skip 40 minutes*~~ (I got lazy and we know what happens here)

"I can not believe you two!" Rohdy hollers at the Stark siblings. "Do you realize how much trouble you could have gotten in? How much trouble I could have gotten in!" Rachel flinches at his yelling and tries to hide behind Tony, it was something she did when she got really shy after their parents died. Besides glaring at Rohdy, Tony hadn't moved. Rohdy sighs and sits in a chair and looks at Pepper, who was working as this was a normal occurrence in the Stark house.
"How can you put up with them?" He asks the quiet assistant.
"Chele isn't that bad, as long as she isn't competing with Mr. Stark over something, which is exactly what all this is about, kind of. As for Mr. Stark.....I have no idea how I'm sane." Pepper says without missing a beat. Rachel huffs, she's competitive, but not so much that she'd risk her neck with Tony to prove herself, and she mentions this, all three of the others in the room turn to her quickly and answers all at the same time.
"Yes you would." Rachel stares at them with her mouth open.
"I feel highly insulted by that." She sticks her nose up in the air, her British accent coming out, and huffs. Tony wraps an arm around her shoulders and pulls her into his side, before falling onto the couch pulling her down with him, practically on top of him.

"I know Pepper will get me back later for saying this, but Tonie in this cat suit, you look kinda hot. And from a brother's standpoint, you are no longer allowed to wear it." Tony says looking over his younger sister, who scoffs at him.
"I think not metal man. I am an adult I can wear what I want when I want."
"And I'm not going to do anything do anything to you Mr. Stark, that is all Chele's job, mine is to make sure she doesn't kill the CEO of Stark Industries and leaves your face alone for the press." Pepper cuts Rachel a look, who smiles at the assistant.
"Hurt my dear brother's face? Never!" Rohdy rolls his eyes at Rachel's acting.
"And why is my sister 'Chele' and I'm 'Mr. Stark'?" Tony asks Pepper who smirks at him pleasantly.

"You are my boss, she is not. She remembers my birthday, you do not. She is my friend, plain and simple." Pepper says as Rachel rolls her eyes at her brother's forgetfulness. For a genius he's pretty stupid.

"Speaking of your birthday, are we going to China this year?" Rachel asks Pepper, tilting her head to the left a little, Tony looks between the two girls.

"Hold on! Are you telling me the times that you've ever asked off, are the times Rachel carts you away to God knows where, to spend money?" Rachel smirks at her brother mischievously.

"Oh brother, there are things I do that you have no idea about. And don't worry it's not ALWAYS your money being spent. I use some of my own sometimes too." Tony stares at his sister incredulously, who smiles back at him innocently while Pepper bites her lip to keep from laughing.

"Anyways, do you know what the media has been calling you two?" Rohdy asks gathering all the attention. Rachel shakes her head to answer his question. "The Iron Siblings." Rohdy looks at Tony then at Rachel, as the two trade looks and identical smirks appear on their faces."Iron...." Tony starts."Siblings." Rachel finishes and leans into her brother's side."I like it!" The two say together. At that moment in time the only difference between the two was the eye color, everything, from the attitude to the smirks were on point.
