Prologue

"How did I not notice?" Thor asked distraught, looking from the injured form of his brother drinking a glass of scotch Tony had passed to him, to the hologram Tony had pulled up of Loki with bright blue eyes showing off that Loki had been controlled into attacking New York and controlling Clint, Selvig and many others. "Brother, I am so sorry, can you ever forgive me? Who did this to you?" Loki smiled tensely at Thor and the others as he told them what happened after he fell off of the Bifrost Bridge only to be interrupted by Jarvis.
"Sir, there are some people in the lobby asking for you." Jarvis announced.
"Tell them that he's busy -"

"Be quiet Rogers this is my home you have no say here!" Tony snapped, he just wanted them all gone so he could continue looking for his baby girl. "What do they want, J?"
"They have a young girl with them that looks like the missing young Miss." Jarvis informed Tony, shocking the Avengers into silence.
"Pull up the footage of the lobby please." Tony requested, immediately, his heart beating a mile an hour as it felt like it was going to beat right out of his chest. A second later a footage appeared before them of a beefy blonde man yelling and demanding to see Tony, a dark haired, long-necked and horse-faced woman who Tony recognised as Lily's sister, Petunia; a large boy who looked so much like his father with his mother's colouring; and a small but beautiful young girl. She had Tony's dark brown almost black curly hair - which no doubt most thought she inherited from James - and Lily's bright emerald eyes.

Tony had met James and Lily in a pub a decade ago - where after several drinks and explanation of James not being able to have kids - the three had an amazing night together and kept in close contact with each other and even became best friends throughout Lily's pregnancy. Tony took any excuse he could to travel to England to spend time with his daughter who had been Blood Adopted by James and Sirius when she was born.
"My little Bambina." Tony gasped tears gathering in his eyes upon seeing the state she was in as fury burned white-hot within him. Her right hand was in a cast, she had multiple cuts on her face and a black eye, not to mention that she was flinching at the loud noises and had backed herself away into a corner away from her uncle and security. "J, what's happened to her?"

"Tony, who, who is that?" Natasha and Clint asked hesitantly.
"That's Valentina. My daughter. She was stolen from me when she was a baby after her mother and stepfather were murdered." Tony replied, eyes still locked on the image of his baby.
"It appears Sir, that she has been injured quite severely in multiple ways. She seems to have been abused and is severely underweight, her uncle is also demanding quite a lot of money before he hands her over." Jarvis added, interrupting the stunned silence that had fallen on the Avengers at Tony's revelation.
"That Bilgesnipe!!" Thor thundered, lightning crackled all over his body as he glared at the image of Vernon, his fist clenched tight around Mjölnir.

"Let security know I'm on my way down." Tony stated, heading into the lift.
"Tony, wait! We have to -" Rogers demanded.
"I have to do nothing other than get my daughter away from them. I have been searching the globe for her for a decade and if any of you try to stop me you will surely regret it!" Tony threatened as the doors to the lift closed.
"Why would you try and stop Man of Iron from being with his daughter?" Loki asked, confused. "Do you have no compassion for your teammate? Wonderful friends you have here, brother." Loki griped, rolling his eyes, but Thor along with Natasha, Clint and Hulk were heavily frowning at Rogers as well.

"I do not condone this brother. Friend Tony should be allowed to see his daughter, you should be ashamed, Rogers. Come brother, we shall help Friend Tony deal with these Bilgesnipes before we return to Asgard and inform mother and father the truth of what has happened to you. I shall not let Father harm you, or throw you into prison, I swear to you brother. I apologise for not being a better older brother."
"Thank you, brother." Loki beamed, heading to the lift.

"WAIT!" Rogers shouted but once again he was ignored, he looked to the two assassins hoping they would agree with him but instead they ignored him apart from throwing him a dark glare and heading into the same lift with the two Gods.
"Puny man!" Hulk scoffed, punching Rogers into a wall with a smirk before he headed downstairs, changing back into Banner as he went.

As the lifts opened into the stylish lobby that held a cream wall on the north side wall where the doors and lifts were located but the rest were all made of tempered and reinforced glass and with tiled floor in Aztec white and light blue pattern, Tony could hear that all hell had broke loose, and despite Tony informing Jarvis to lock down the tower - (he didn't trust or need S.H.I.E.L.D interfering and informing his Godfather Nick Fury the truth of the attack on a privet line) - his receptionist was still trying to get them to leave the premises; even though all staff members had received the lock down notice and was actually making the situation worse than it needed to be.

"I'm sorry Sir, but as New York was just attacked by aliens, Dr. Stark is very busy so I suggest either leaving your name and contact information and we'll get in contact when Dr. Stark is free or you make an appointment." The receptionist said in a blasé tone of voice.
"I WILL NOT MAKE A RUDDY APPOINTMENT!" Vernon Dursley roared, banging his meaty fist on the glass reception desk, spittle flying from his lips as his face turned a puce colour. "WE'VE COME ALL THE WAY FROM ENGLAND TO GIVE HIM, HIS FREAK OF A DAUGHTER, AND WE ARE NOT LEAVING UNTIL WE ARE COMPENSATED!!" As he got angrier at the lack of cooperation from the staff, Valentina backed her injured body into a corner as far from him as she could while trying to make herself as small as possible.

"Muummyy!" Dudley whined, stomping his feet, adding to the demeaning volume of the lobby. "I'm bored! How long will it take to be rid of the freak!"
"I know Duddikins, but as soon as we are rich from being compensated I'll buy you all the toys you could possibly dream of." Petunia placated her son causing the security guards to cringe at her lack of proper parenting.
"I don't much care for your tone, Sir." The receptionist was saying to Vernon over the boys' whining and complaints.
"WELL, I DON'T CARE FOR THAT FREAK THAT GOT DUMPED ON MY DOORSTEP A DECADE AGO!" Vernon thundered, just as Tony rounded the corner from where the lifts were located at the back of the lobby through a set of double oak fire doors.

"What!?" Tony shouted, causing the noise to rapidly cease. "Why was I not informed immediately of their arrival... Valerie?" Tony asked, pausing to read her name tag which caused the blonde woman in her thirties who wore far too much makeup to scowl. "Why did it take Jarvis to inform me when it is your job."
"Well, I thought that given all the rumours, this  man's claim was fake." Valerie replied unrepentant.
"Excuse me?" Tony demanded. "It is not for you to decide what is important or not, consider yourself on a warning and up for a review!" Tony snapped.

"Everyone in this building knows I had a daughter stolen from me a decade ago and I have scouted the globe for her. Now, obviously someone kept her hidden from me and I will find out! And instead of removing my daughter from this hostile environment you've all made it worse! Scott, Aaron, take these despicable people to the security holding. Jarvis, contact the police, Rhodey and C.P.S and inform them my daughter has been returned to me but by her abusers who are demanding the British equivalent of $10,000 from me for her return!" Tony ordered, once they were gone he slowly approached his terrified daughter.

"Hi Bambina, I'm your Daddy Tony." Tony smiled reassuringly at his baby girl, trying to make himself seem as non threatening as possible - despite the armour he still wore - to his terrified little girl who clutched a cage tight to her chest that contained a beautiful Snowy Siberian owl who barked at him while seeming to glare at him with bright amber eyes. "Can I sit?" He asked, pointing to the tiled floor a few feet from her, smiling blindingly when she nodded shyly. "That's a beautiful owl, what's her name?"
"Her name's Hedwig. I... I remember you a-and Dadfoot." Valentina whispered, a far away look in her eyes as she recalled a distant memory.

"That's right baby." Tony praised, before a horrifying thought struck him. "Do you remember everything, Tina?" Valentina nodded quickly, tears gathering in her luminous emerald eyes.
"Yes. I even remember when Mum and Daddy James died." She whispered causing Tony to close her eyes in horror and those around them to gasp. "Are you really taking me from them?" She asked cautiously.

"I am, sweetheart. You were stolen from me and I haven't once stopped looking for you." Tony confessed, slowly moving closer to his baby. "Who hurt you, mini-me? Was it them?" He asked, barely keeping a hold on his anger that felt like a volcano inside him as Valentina nodded slowly, cautiously as if she was afraid to be hurt again.
"And from school. A teacher and the man who killed them." Valentina whispered so only Tony - and Thor and Loki who stood in the background keeping an eye on the receptionist Valerie - could hear.

"Jarvis, contact Dr Stephen Strange. Let him know what's happened and that I need him here ASAP." Tony ordered once more.
"Of course Sir." Jarvis agreed, attracting a curious look from Valentina as she looked from the ceiling to her father.
"Jarvis is an A.I. isn't he?" She asked shocking Tony but a pleased grin quickly stole across his features.
"Correct Mini-me, well done." Tony praised, getting a beaming smile from his baby girl. "I promise that no one will ever hurt you again, and those that have will pay. How about we go up to our apartment and watch some cartoons until my friend Dr. Stephen Strange comes to look you over, as well as the police for those people?" Tony suggested, standing and holding his hand for his daughter.

Slowly Valentina eased herself from the hard floor and took her Dad's hand, Hedwig still held close to her chest but now with her broken arm while Tony grabbed her trunk.
"Man of Iron, I shall keep an eye on things down here." Thor told him, lowering the volume of his voice when he noticed the little girl jump startled.
"I shall accompany you to make sure Rogers doesn't bother either of you. Those assassins have secured the Sceptre in a conference room on the ninetieth floor, and I think Dr. Banner is back to normal." Loki added, nodding to Bruce standing near the double doors.

"Thanks Point break, Reindeer games." Tony said gratefully. "Sweetheart, this is Thor the God of Thunder and his brother Loki the God of Magic and Mischief, and that man by the doors is -"
"- Dr. Bruce Banner!" Valentina squealed excitedly, making everyone chuckle especially as it reminded Bruce of how excited Tony was to meet him. "My friends Fred and George would love to meet Loki, they love mischief, chaos and pranks." At the mention of boys a scowl appeared instantly upon Tony's face making the three men chuckle.
"Well it would be an honour to meet them and it is an honour to meet you -" Loki trailed off, looking to Tony to introduce her. He didn't want to startle her by knowing her name before meeting her.

"Right. Guys, this is my daughter Valentina Rosa Potter-Stark." Tony introduced. "Bruce, I know it's not really your forte but could you look her over until my friend arrives please?" Tony asked, glancing worriedly at his daughter as she winced with every step.
"Sure Tony." Bruce agreed. "I can start a profile for when the police and C.P.S arrive."
"Perfect, thank you." Tony replied gratefully, ignoring S.H.I.E.L.D Task Force who were trying to get his attention at the front doors but he has more important issues to deal with; namely making sure all who hurt his baby paid, getting her healed and comfortable, and protecting her from everyone and all threats. No one was taking her from him ever again. He'd watch the world burn if it meant protecting her.

Second Author's Note: This will be a Tony and Loki pairing (love Frostiron) but who would you like to see Valentina with from HP? It can't be Peter Parker as he will be like her older brother. Comment and let me know.

Thank you Arcstark for the banners.
