Loki's Twin, Tony's Sister

I WIN

In the middle of practically no where Miami, Florida, a front door opens revealing a 5'9 black haired beauty, in cut off booty short jeans, and a black tube tank top, her bright greens eyes flint around the living room.
"Miss Stark?" A ginger woman in a business suit asks the 34 year old girl standing in the doorway.
"Miss Potts!" The girl rushes forward taking the business woman by the arms and places a kiss on each of her cheeks. "Now where is my jerk brother?" A smirk takes over the red lips of the younger girl as she looks at her brother's P.A, Pepper Potts (Personal Assistant), who rolls her eyes and smiles back at the girl.
"His lab where else?"
"Oh I don't know, with the last walking STD he's brought in." She says, he face scrunching up in disgust, while her voice getting a slight english accent as her anger rises, causing Miss Potts to laugh.
"Oh trust me, I took the trash out quickly, especially after the last time you came back and one of them started yelling at you. Tony learnt from that little adventure." THe ginger laughed and smiled at the smirking Stark girl.
"Ha, yeah....Anyways I'm going to bug my brother now, that he's back after three month." The girl turned to lean, and waved to Pepper over her shoulder, leaving the ginger woman laughing. The girl descended the stairs and to the glass sound proof lab/garage, her brother was working in. The girl stopped at the door and touch screen part of the glass holding the keypad. Putting her number into the system the door buzzed open and automatically turns down the rock music her brother was blaring.
"Hey! Do not turn my music off Ms. Potts." A black hair man yells out from behind the red and gold project.
"I guess it's a bloody good thing I am not Pepper, then huh, my dear big brother? The same big brother that has been missing for three months and doesn't even THINK to contact his little sister, who has been in England when all of this happened, and was forbidden to return home because they maybe after me as well, so big brother, how do you feel?" As she talks she slowly stalks her way to her brother, who had come out of behind his project, noticingly gulping, and slowly leaned on the project as she got in his face, at the end she smiles sweetly, her eyes closed, but her hands, which were behind her back, clenched in a deadly grip, ready to hit him.
"Ah! Well, you see-" He starts only to stop quickly as one of her hands fly up and she points at him, her smile gone, and her green eyes cold, hard, and practically venomous.
"DO. YOU. HAVE. ANY. IDEA. HOW. WORRIED. I'VE. BEEN ANTHONY EDWARD STARK!!!!" She yells at him loudly poking him in the chest, just over his heart, and mere centimeters away from the glowing arc reactor under his shirt. She brings her hand back, open palm and Tony flinches thinking she's gonna hit him. She stares up at her brother two seconds before collapsing into his chest sobbing, his arms wrap around her almost instantly, he looks about trying to find some type of inspiration to make her stop, he almost prefered her slapping him.
"Rachel, I'm fine, I'm alive. I'm so sorry little sister. Please stop crying, Stark's don't cry, remember? Come on Marie-" The crying girl, Rachel looks up, a water glare in her green eyes.
"Don't call me Marie." She growls out, Tony smiles down at his baby sister and wipes away her tears.
"I'm O.K Princess, I swear." He whispers gruffly, hating when his sister cries, she smiles at the nickname, and holds her brother's shirt tighter, like he was going to disappear right then and there.
"I never thought I would miss you calling me that. Three months Tony, you'd been gone and left me, like Mum and Dad." She muttered, her accent stronger now as she lays her cheek on the arc reactor, she knew about it, so she didn't asked as it buzzed lightly. Tony flinches a little at the mention of their parents, he rarely talked about them, but the two siblings missed them. Tony squeezes his sister a little bit tighter, his eyes closing automatically, and he rests his cheek on the top of her head.
"I'd never leave you Tonie, you know that. You need me too much." Tony cracks a smile when the girl scoffs. Her name, Rachel Marie Antoinette Stark, younger sibling to Anthony Edward Stark, the famous kids to the equally famous Howard Stark. When Howard and Maria Stark died, Tony was almost 21, Rachel almost 10. Tony took over raising the adolescent Rachel, giving the two siblings quite a close relationship, they were all the other had.
"You'd better not Anthony, or I'll bring you back and lock you up in a room and not let you out, and I'll change Jarvis." Rachel smirks and leans back to see her brother's stricken face. Tony's face morphs into a smirk as he kisses her forehead.
"Never Princess, never." Rachel smiles at the pet name, the only reason he called her that is because, technically she is the princess of Stark Industries, and named after the famous Queen of France, during the revolution.
"Promise?" The 34 year old looks up at her big brother, sort of mainly up through her eyelashes, giving Tony the same looks she used when she was younger to get whatever it was that she wanted, knowing it would still work.
"On your blue eyes." Tony smiles and flicks her in the nose lightly, like he did when she was ten. Rachel's face lights up, it was a joke between the two, Howard once accidentally got the colors wrong while the two were behind him and he wasn't really paying attention. Now though, Rachel knew it was stronger than a joke between them, it was an actual promise, one that neither one of them had ever broken.
"So what are you working on?" Rachel asks Tony as he turns his back and starts to work on it again. She looked at the suit of red and gold, inspecting it, and making calculations in her head on what could be made better, for her own at least.
"Nothing." Tony deadpans, hoping, futilely, that she'd drop it.
"Fine, I'll go sit at the desk then." She moves to the right of Tony, and towards her desk.
"NO!" Tony shouts looking at the smirking girl, who had just barely sat down.
"Well, it looks likes you have two choices here, tell me, or I hack Jarvis." Tony grits his teeth, his sister was just as smart as him, if not smarter, in some regions.
"Fine." He sighs and waves her over, she quickly gets up and literally skips to his side. "I'm working on getting rid of Stark Industries weapons, with this. It's a suit I've made once while I was captured, I am going to recreate it, make it better, and use it to right wrongs." Tony gestures to the suit.
"What's with the colors?" Rachel asks raising a brow.
"Hod rod colors." Tony smirks, Rachel nods and walks around it. By her own calculations, and modifications, she and Tony could make another suit, one specifically for her, by the end of the night.
"I like the design, what's it run on?" She asks coming to a stop next to Tony, looking at the whole in the middle of the chest.
"This." Tony taps the arc reactor on his chest, Rachel again nods, looking at Tony then the suit.
"I want in."
