With his fangs, the mage alchemist tugged on the Fullmetal alchemist's bottom lip, asking for entrance. The smaller teen complied and soon their tongues were battling for dominance. Edward arched up into Harry, causing their erections to brush. Ed jerked, blushing madly. Harry stared at him with hooded eyes, a seductive smile tugging at his lips. Edward allowed a shiver of pleasure and excitement go down his spine.

Chapter Four: The Past and Battle on the Train

----

He had been fourteen at the time. The war had escalated early and fast, as well as unexpectedly. The ministry was the first thing to go. Soon carnage was all that was left and he was surrounded by dead loved ones. He had just killed the fool who had started it all, and the ones he would give anything to bring back were lying at his feet.

He had come across alchemy when he was in his second year. He had been enthralled and had soaked up all the information that he could get his hands on. He even went as far as to contact Nicholas Flamel. He had the natural ability of it, but there was one alchemy practice that was forbidden. Human transmutation.

However, his friends were at his feet their glassy eyes staring straight through him. Tears running down his face, leaving clean streaks in their wake, he slowly started to draw a transmutation circle around the six bodies. His soft breathes and his drawing was the only sound that broke the still air. He finished the circle and carefully stepped back, gazing blankly at the bodies.

Luna was sprawled on her back next to Neville. Next to the pair was Ron clutching Hermione tightly, and lying next to them was Sirius being gripped tightly by Remus. "I'm sorry, but I can't live without you," Harry whispered.

He slammed his hands onto the ground, making the circle glow and lightning to crackle dangerously. A grin started to form before the light grew brighter and brighter and with a loud explosion he was standing in front of a gate. His grin vanished and the fact that he would never be able to bring his friends back was forced onto his mind. Face impassive he let the gate open and the black creatures grip him.

Their grubby little fingers tore his hand to his elbow off, but their mouths bit chunks off. Soon half his thigh, a thin line on his arm, and part of his neck and his entire ear was also gone. Then a burst of emerald green light and he was in a six year old body with his older mind and he was lying on the doorstep of the Rockbell house.

"WAH! Daddy this is fast! Wow!" a little girl exclaimed, looking out the window of the speeding train.

Her father grinned at her laughing, "You'll get tired if you're having too much fun! Didn't you promise daddy we'd play a lot when we get there?"

His wife wrung her hands in worry asking softly, so their children wouldn't hear, "But is it really okay to take a vacation?"

His eyes softened and he replied, "I was finally able to get a break. Forgetting about work and spending time with the family shouldn't be a sin."

The sudden noise of the compartment door opening caught the four occupant's attention. The door revealed two big and muscled men. The one on the left asked, "You General Hakuro?"

Hakuro tensed and glared, "Who are you? What complete lack of mann—" He was cut off by the end of a gun. He jerked back.

A shadow moved and revealed a rugged looking adult man with his hair in a ponytail and an eye patch over his left eye. "Sorry for screwing up that family get-together you tried so hard to get, General." The man stared at Hakuro intently and spit out, voice dripping with acid, "Your fun family vacation is over. From here on out, let's go on a family vacation of thrills and despair."

Central Headquarters

"The high jacked train was limited express no. 04840, departing from New Optain. This is the work of the 'Blue Squad,' a group of eastern extremists," Riza Hawkeye explained, reading off a sheet of paper as she walked next to Roy Mustang.

"Any statements?" Roy asked.

"We received a manifesto. Would you like me to read it?" Riza replied.

"No that's alright." Roy opened the door to his office, "Let me guess…I'm sure it's full of kind words for the military."

Riza snorted, "How'd you know…?" The two walked up to their station. "They want us to release their leader. We've got him in prison."

Roy snorted this time, "How predictable. So is the general really on board?"

Vato Falman was the one to reply, "We're verifying that right now, but it's likely."

Roy scratched the back of his neck, "Man, what am I going to do? I have a date set up later in the evening."

Heymans Breda held up a steaming cup of tea and continued to read the newspaper, "It wouldn't hurt to have an overtime date with us once in awhile. Complete with nasty tea."

"I guess the general's just going to have to sacrifice himself so that we can wrap this thing up right away…," Roy stated sagely, eyes closed and his gloved hand holding his chin.

Kain Fuery raised an eyebrow, handing a piece of paper to his higher officer, "Don't be ridiculous, colonel. Here's the list of passengers." Roy took the papers and started to skim over it.

Over his shoulder Jean Havoc also skimmed over it, commenting, "Ah…old man Hakuro really is on board with his family."

The dark haired colonel sighed, "Good grief…I'm sure he knew the situation out east is unstable, and yet he comes here on vacation…" Still scanning the paper two names popped out at him. He raised his head from its previous resting position, "…Hold on, everyone! I think we can go home earlier today than we thought." He smirked, "The Fullmetal and Mage Alchemists are onboard."

The Train

----

Harry breathed softly as his head rested on Edward's lap, sleeping. The blonde was sleeping as well, but was snoring quite loudly in the silence. Edward's gloved hand was resting on his lover's head and his other hand was entangled with one of Harry's hands loosely. The two slept blissfully unaware of the sudden hold up on the train. One of the gang members sweat dropped, gun swung carelessly over his shoulder, "…How can these brats sleep through all of this?" The man poked Edward's cheek then Harry's with his gun, "Hey! Wake up!" The two continued to sleep, though Harry's top lip twitched. A vein threatened to pop on the man's forehead, "Why you…Act more like a hostage…YOU LITTLE RUNT AND GIRLY LOOKING KID!!"

Harry's and Edward's eyes snapped open and both stood up slowly, a dark and menacing aura surrounding them. The guy blinked, "Huh? What? You got a problem or something!? Huh!?" The guy pointed his gun at Edward, who was the closest. The small blonde clapped his hands on the gun and with a bright flash of light and lightning crackling the end of the gun turned into a trumpet. "Whoa!? WH-WHAT THE HELL IS THIS!!?"

Two legs shot out and kicked the guy in the face, sending him flying to the other side of the train. A dark smirk slithered onto Harry's face and he cracked his knuckles in a threatening manner. The other gang member cocked his gun at Edward's Harry's head, "That was dumb, kids. We were ordered to kill all resisters. I don't want to shoot a runt and girly looking kids like you but…"

Al made a move to take the gun away, but Harry's finger pressed against the underside of the man's wrist harshly. The male cried out in pain, dropping the gun. This also caused him not to see the flying knee kick Edward was sending his way. The two lovers then proceeded to beat the living daylights out of the gunman. Edward was shouting, "YOU CALL ME A RUNT?! A DWARF? A 'LITTLE PERSON'!?" while Harry was shouting, "WHO ARE YOU CALLING A GIRLY LOOKING KID!? I DO NOT LOOK FEMININE!!"

Alphonse waved his hand carelessly, "Big brother! Harry! If you don't stop, he's gonna die!"

Edward stepped back, eyes blank. Harry, on the other hand had a foot placed on the back of the gunman's head and was scowling darkly. Ed looked over at Al, "So, um…who are these guys?"

Al hung his head thinking, 'So they were just subconsciously reacting to the respective insults toward them…'

----

"Besides us, there are two more in the engine room and four more in the first-class car guarding the general. There are four in the coach car standing guard in different locations," the gunman explained.

Ed held a fist out, face all smiles, "And the rest?"

Gunman squeaked, "That's it! Really! There's no more!"

"There's still ten more of them!"

"What are you going to do now? When they hear you beat up their men, they might come retaliate…!"

Alphonse shrugged, "If some people were more mature, this might have ended peacefully."

Both males hinted at twitched and shouted together, "YOU CAN'T MOVE FORWARD IF YOU KEEP REGRETTING THE PAST!" Edward clasped hands with Harry and continued, calmer, "What's done is done. I'll go above. Al, love, you take them from below, all right?"

Al waved a hand, "Sure, sure."

Crackling lightning emitting from the ground soon cleared away to show Harry's choice of weapon. A large scythe was grabbed by a gloved hand and a shit-eating grin took over Harry's face. "Of course, kitten," the dark haired teen purred.

"Wh…who are you guys?" a passenger asked.

Edward paused in climbing out of the window, grinning. Alphonse stood next to him, posture straight. Harry reclined on a bench lazily, scythe resting over his shoulder and the back of the bench. "We're alchemists!!" Edward answered. Then he was gone and on the roof of the train. "…Hup. Well then…why don't I give it a shot!"

Harry threw his head over the back of his seat, staring up into Al's helmet, "So…how are we doing this? Do I get to scare them shitless? Or do you want to stand there and try to do it peacefully but end up with them shooting at you and the bullet ricocheting back at them?"

Al sweat dropped, those really were the only options. "Well, you haven't gotten much excitement lately, well, barring the sex, so I guess we'll go with Plan A," the suit of armor responded with a shrug. Harry's reply was an evil grin and standing up with his scythe.

----

A guy wearing a bandana, so we shall call him Bandana picked up the radio but received no response. "Hey, weird. Our men in the rear aren't responding," Bandana stated. He opened the door, "I'll go check it out."

The other guard there, one with suspenders, thus he is dubbed Suspenders, replied back, "All right."

Bandana sighed, "…Man…they're supposed to call in to report…" He then noticed the suit of armor casting a shadow over him. Clearly not thinking he started to shoot at the armor. However, Harry's prediction turned out correct when a bullet ricocheted back at Bandana and hit him in the thigh.

Suspenders rushed in and seeing Al also started to shoot, before also getting hit. Harry slipped out from behind Al, his scythe's blade glinting in the light. "Hmm, it looks like we ended up doing part of Plan B as well," Harry commented looking down at the two fallen men.

Suspenders, since he doesn't get much screen time, looked up at him with a small amount of fear, "…Who are you?"

A dangerous smile spilled onto Harry's face and in a dark and demonic voice he whispered, "Your worst nightmare."

----

"Hey, Bald." You remember that guy back in the very beginning? Yeah, you know the guy that took over the train? The one with the ponytail. Yeah, him. His name is Bald, which totally contradicts his looks considering he has hair, but anyhow, that's not what we are talking about! "Contact with the rear car has ceased," a big guy with dark skin announced, holding the radio; oh, and he's dubbed Scary.

An underling wearing a trench coat, now dubbed Trench, asked, "What does that mean?"

Bald paused for a moment before replying, "…There's someone onboard. We took care of all the guards, and we've cut all communications to the outside. There's no way a passenger could call for help…"

"Did one of us turn traitor?" Trench asked.

"Couldn't be!" Scary answered.

Hakuro snorted, sneering, "You're nothing but a bunch of trash. You fall apart as soon as our little plan starts to go wrong. Things aren't going to go how you want. Now's the time to start thinking about surrender…you slime."

A shot rang out and part of Hakuro's ear blew off. He gritted his teeth and his hand hovered over his ear, not daring to touch it. "AGGGGH!"

"Don't speak until spoken to. Next time the hole won't be so little," Bald stated. Footsteps suddenly sounded on the roof and Bald cocked the gun on his arm back and started shooting at the roof. Bald jerked his thumb at a fat underling, who is now dubbed Fatso, "It's a rat. Go check above."

----

Edward held his leg up straight, sweating, "Whoa, that was too close!" He took his boot off and examined his automail. "Man, if it weren't my left leg, I would've been gone." He took the bullet out and put his boot back on. He held the bullet and scowled, "Dammit! Just you wait…First, I'll recapture the engine room!!"

Unseen by the four men in the engine room, Ed chucked the bullet into the room. The guard with no hair, now dubbed Baldy, picked the projectile up, eyebrows furrowed, "A bullet?"

The other guard with spiked hair, now Spiky, leaned in closer, "Where did that…" Spiky never got to finish as Edward entered with a kick to Spiky's head. The force of the kick sent him face first into a pipe.

Baldy made a move towards the blonde, "Why you…" he didn't get to finish either, but it wasn't Edward who shut him up, it was the two engine room guys, Muscled and Scrawny, and their Shovels Of Doom ™. When Muscled and Scrawny finished beating Baldy with their Shovels Of Doom ™, the three conscious gave each other bright thumbs ups.

Edward climbed up the ladder on the side of the train, but paused when Scrawny asked, "Anything I can do?"

Edward smiled sweetly, "Just drive safely, please!" Pulling himself up to the roof of the train he came face to face, well not really but anyway with Fatso. "Hup…"

Fatso leveled his gun at Ed, "There you are, you rodent." Edward quickly ducked when Fatso started to shoot.

Before Fatso could start shooting again, Edward jumped onto the roof and made a cannon, quickly firing, "THAT WAS DANGEROUS, YOU JERK!"

Fatso screamed and ducked back down, panting. Scrawny leaned out the window and called, "Hey!! What are you doing to the tender car!!? That's got the water and coal for the whole train!"

"Oh! Sorry!" Ed called back. Once back on the roof, a childish mental diagram of the tender car appeared in his head, "Hmm? The tender car?" Sitting on the edge of the cart full of coal and water, he rapped his knuckles on it, "Hmm…"

Down below Fatso screamed hysterically, "BALD! THAT'S NO MOUSE! I DON'T KNOW WHO HE IS, BUT THERE'S SOME CRAZY GUY UP THERE…!"

Scary held the radio to his ear and called out harshly, "Hey, car no. 2! What's going on!!? Hey!!"

"Help…He's insane! Death is here!!"

"DEATH!? What the hell are you talking…"

"AGGH! GYAAAAAAHHH!" There was silence and Scary, Fatso, Trench and Bald stared at the radio in wonderment. "Hello~ my little chicklings! This is Death speaking~! Your little Bandana and Suspenders are under my tender care-HELP ME!-SHUT IT SUSPENDERS, NOBODY ASKED YOU!! Anyhow, I have to go now, kitten is telling me to get off the radio now, so ta-ta~ my little chicklings~!!!" There was maniacal laughter before the line cut off into dead silence.

A loud clank and then a 'floop!' and a little speaker in the shape of Ed's head appeared on the wall. Together Fatso and Trench thought, 'Floop…?' "What the…?"

Then Edward's voice crackled over head, "Hello, hello. Calling all hijackers. We have recaptured the engine room and the rear cars. This car is the only one left. Please lay down your arms and let the hostages go…If not, we will have no choice but to use force."

Bald glared at the speaker, "What a joke! I don't know who you are, but as long as we have the hostages, we'll never give up!"

The eyes on the speaker glared, "Oh my, you're still going to resist? Too bad…talk's over. Bye."

A large water pipe suddenly exited the wall and Trench stared at it in confusion, "Is that a water pipe…?"

The speaker spoke once again before ceasing to exist, "All passengers please take cover."

Edward turned a knob and Bald shouted, "RUN FOR YOU'RE…" He was cut off as water exploded from the pipe.

In the next cart Al opened the door and the underlings washed in. They looked up an Al punched his fists together, "Welcome." Harry slipped out of his friend's shadow, Scythe swung over his shoulder and a feral grin shown to the world.

Breathing heavily, Bald slowly stood, water weighing him down, "We're not through!! We still got the hostages…"

His eyes widened when Edward jumped down in front of him, creating a blade from his automail. "Well, well…someone else with an automail arm?"

"Y…" he started. Then he snarled and yelled, aiming his gun, "You're just a little brat!" Before he could lunge Edward was already shoving his knife through the gun.

"You know…" Al grabbed Bald's shoulder and reared his fist back and Ed finished, "…You bought the cheaper model, didn't you?" Ed tore his knife out and Al slugged the man.

----

"Hey, Fullmetal," Roy called, hand held up in greeting. Edward made a disgusted/angry look.

Al looked up and waved in greeting, "Oh, hello, colonel."

"What's with the unhappy face?" Roy deadpanned.

Edward rubbed his forehead angrily, "#$%...I wouldn't have helped t if I knew it was in your district!"

Roy crossed his arms, "You still don't like me…huh? I guess you're still not back to normal."

Before Ed could reply Harry kicked Roy's back sending him forward and onto the ground. Acting as if he didn't have a foot on the back of a colonel's back, Harry took a bite of his pocky, smiling brightly, "I'm back, kitten!"

"You're causing commotion wherever you go like always," Roy grumbled angrily, only to eat dirt as Harry walked off him, by going forward.

Still wearing a bright smile, "Do you hear something, kitten?"

Edward snorted quietly, "Not at all, love, not at all."

"AGGGGH!"

"STOP HIM…AGGGH!" Bald stood up angrily, a hidden knife protruding from his metal arm. He snarled angrily, breathing heavily. Riza readied her gun, but Bald was already charging for them. A flash of black was all that indicated Harry was on the move. Harry stopped right in front of the man and his hand shot out and gripped Bald's face.

Green fire covered his hands and black lightning crackled all over his body, lashing out around him. With his other hand Harry summoned his scythe out of thin air. Pressing the blade against Bald's throat Harry hissed out darkly, "Never ever charge at my family, scum." The feral look in the teenager's eyes made Bald go limp in prey submission. Harry scoffed tossing the man at some of the other soldiers.

Bald shook in fear, "Wh…Who are you?"

Harry sneered, "Harry Potter. Rank: State Alchemist also known as," a feral grin replaced the sneer and the next words dripped with acid, the deadly look in the dark haired male's eyes returning, "The Mage Alchemist. Remember it."
