New story, very exciting.

This story will contain spoilers for the manga and Brotherhood. It is based on that story line, so don't expect any otherworld stuff or Dante or anything like that.

I've wanted to write a story with the next generation for a while. I've had many ideas and this has been the best thought out and my favourite so here it is.

Disclaimer- Guess what, I don't own FMA in anyway shape of form.

Prologue – Protect Her

The two soldiers started awake to the sound of someone pounding on the door. The female dived off the bed and grabbed for the gun that was on the table beside the bed. The man snatched gloves from under his pillow and pulled them on while slipping out of bed.

"I'm pretty sure an assassin wouldn't be knocking," the dark haired man said."Go back to bed." He gestured at it before leaving the room, he didn't remove his gloves.

The blonde haired woman ignored his instruction and stepped out onto the landing. She didn't follow him downstairs instead carefully aimed her gun at the door.

Roy Mustang wasn't sure what to expect when he answered the door at gone 3 in the morning, it wasn't however, a tired and frightened looking Edward Elric. Ed pushed his way past Mustang and kicked the door closed. Roy briefly studied the boy – no, man. He'd grown, though was still a head shorter than Mustang, his hair was in a high pony tail and he now wore more conservative clothing. It was obvious he was hiding something underneath his worn brown coat.

"Fullmetal," Roy said by way of greeting. Ed growled at the use of his former title and turned his eyes, which had previously been scanning his surroundings onto Roy. It was then that the elder became aware he was standing there in nothing but some loose pyjama trousers and his gloves. Ed's eyes focused on the gloves with a look of mistrust. Mustang pulled them off quickly. "What do you expect when you come pounding on the door of the leader of this country at stupid hours of the night," he said by way of explanation, "and what's more, how did you get past the main gate and security."

Ed merely gave him a look that said 'it's me, what did you expect'. The bundle under his coat squirmed drawing both men's attention. Ed moved his coat aside to reveal a baby nearly six months old, it started to cry. He pulled it close, rocking it back and forth while making soft comforting shush sounds.

"Edward?" Riza said coming down the stairs, her sleepwear covered by a silk dressing gown Roy had bought for her. She handed him the shirt of his pyjamas and he gratefully slipped it on. "What's wrong, Edward," she said to the young man. He tore his eyes from the child in his arms and looked at her.

"You have to help me," he said, he voice full of the fear that was written all over his face. Roy didn't think he'd ever seen Ed like this and it worried him. The baby bawling increased in volume as chubby hands reached up and latched on Ed's pony tail, which hung over his shoulder, and pulled. He winced but didn't stop the child. "She needs food, can you get some warm milk please. There's a bottle in here." He shrugged off the satchel that Roy hadn't even noticed. Riza nodded and took the bottle out of the bag before hurrying off.

"Come in here and tell me what happened," Roy said gesturing for Ed to follow before picking up the bag and walking towards the lounge. Ed followed quietly still shushing the crying baby.

Once they were seated Roy asked the question he'd been burning to ask since Ed pushed his way into the house.

"What happened?"

"They want to take her away from me Roy. They can't have her I won't let them take her but I can't keep her now." He was bordering on hysterical now.

"Ed, I don't understand. Start from the beginning," Roy instructed. The younger man took a deep breath and resumed rocking the baby gently. When he looked back at Roy he was calmer.

"This is Lucy, Lucinda, she's my daughter. A few days ago some men came to my house and said they wanted her for an alchemy experiment, said she'd become the most powerful alchemist ever. Like I was ever going to say yes, but you see these men didn't leave they hung around. I got the message; they would take her with or without my permission. So I ran. Winry doesn't know. I can't believe I've been forced to do the very thing I hated my father for. My son will probably hate me now." Ed eye's dropped as a look of sadness passed over his features before he seemed to shake himself and carry on.

"It's only a matter of time before we're found. I need her to hide somewhere safe. I've wracked my brains but there is only one way I can think of. Roy, she needs to be someone else's daughter."

"Are you asking me what I think you are?"

"Please Roy, you have to take her."

"Why me, you don't even like me. There must be someone else. Why not go to the police and tell them what happened. They can protect you. You're being illogical Fullmetal." Roy's cool was broken slightly. He was beginning to hope he was going to wake up in his bed in a minute.

"These people are too well organised for the police. The military might be able to take them out but by the time they do it'll be too late. As for why it has to be you? It's because no one else can make it look like she's their daughter. No one would dare touch your child. I'm hiding her in plain sight."

"And if I refuse?"

"Hold her Mustang," Ed passed the baby to Roy, who after a hesitant moment took her. The child, who had still been fussing looked slightly bemused at the new face above hers. She took a moment to consider it then gurgled happily. Despite himself, Mustang could not help but crack a smile at the child.

"You're wrong, you know," Ed said, "I don't dislike you. I respect you. You've done a lot for me and my brother. You've done a lot for this country. You've turned this country into a democracy and still managed to come out on top. Please you have to protect her," Ed pleaded.

"It's really hurting your pride to say this isn't it."

"Yes but this is bigger than that. Will you do it will you look after. Promise me."

Roy looked long and hard at Ed, before sighing.

"I promise," Roy said quietly.

"Thank you." Ed leant over the child in Roy's arms and kissed her forehead. When he looked up he nodded to Roy, then spun on his heel and left without a backward glance.

When Riza Hawkeye returned with a bottle of warm milk, Edward Elric was nowhere in sight. Instead Roy sat in his high backed arm chair cradling the child.

"Where's Edward?" she asked.

"Gone," came the reply.

"Gone? Where? He wouldn't leave his child."

"He just did Riza, she's our daughter now."

"I don't understand." Riza sat down in the chair opposite his and handed the bottle over. Roy shifted the child then offered her the bottle which she latched onto happily. He looked across to Riza and began to explain.

15 years later...

"Please."

"No."

"Pretty please."

"No."

"Daddy, come on, please."

"I said no!" Roy Mustang slammed his hands on the table top and glared at his daughter, "You are too young to date."

"I'm fifteen, I am not too young to date."

"You're too young to date if I say you're too young to date."

"You're being unreasonable."

"I'm being unreasonable? You're the one who's trying to send me to an early grave through worry."

"You're so melodramatic Dad. You know I'm going whether you say I can or not."

"Evelyn Lucinda Mustang, you will not be going out. I will lock you in your room if I have too," Roy shouted causing the girl to step back a bit. It wasn't often that her father yelled at her.

"I'm sorry Lou," Roy continued in a softer tone, "I've got a lot on at the moment. I have a meeting now can we talk later."

"Sure Dad, are you ok?"

"Of course," Roy replied kissing her on the head as he walked past. He held the door open for her and she stepped outside his office before he closed the door behind himself.

During fights with her was one of those time Roy was made painfully aware she was not his real daughter, she always look so much like Ed when she yelled.

Just a couple of notes:

1. Her name doesn't mean anything, it's not symbolic at all. I just tried to pick old fashioned names that I liked.

2. Incase you were wondering, at the start Ed is 23 and Roy is 37. For the main part of the story, Ed is 38 and Roy is 52.

I hope you enjoyed this first installment. I can't promise this will be updated very quickly I am still working on I Want You as well. I'll try to be as quick as I can though.

Please do let me know what you think!
