Edward Elric with his younger brother Alphonse were walking back home at night-time.
It had been a long day of State Alchemist duty in the East-City Amestris military.
Edward was muttering to himself about one day, he will surpass Roy Mustang to become so tall everyone else in the world would appear small. Alphonse merely shook his head to listened quietly to his older brother.
The alchemists went into an old abandoned alleyway before Edward suddenly crashed into an eccentric-looking young man who appeared from nowhere. The man had dark hair, a thin face with sunglasses, a grey overcoat, and a blue scarf.
"Blimey! I do apologize." the man smiled, exclaiming in a strange accent. "I wasn`t looking where - blimey, aren`t you Edward Elric, the Fullmetal Alchemist?"
"Yeah mister, I`m - " Edward began, only for the man to shake Alphonse`s metal arm so hard, it looked like it was about to fall off.
"I`ve heard so much about you! I`m the Doctor, really wanted come to face a real-life alchemist of Amestris! You know, I began to study alchemy myself to discover the secret of the - " the man began
"Umm...I`m sorry, it`s not me. I`m his younger brother, Alphonse." Alphonse responded awkwardly.
"Oh, I knew the entire time!" the man exclaimed gently. "I wanted to observe your older brother when someone finally recognizes he is the Fullmetal Alchemist before accidentally calling him short - "
"Who are you calling a little microscopic midget so short, everyone thinks he couldn`t drown because he is small enough to breath oxygen molecules through the water, you ▂▂▃▃!?"
The Doctor smirked. "I told you so."
"Brother, please!" Alphonse tried to restrain Ed from jumping onto the madman, who reached out to inspect a surprised Edward`s automail arm before speaking.
"Ah..." the Doctor began solemnly. "Since I finally found you, I am here to give you two a warning."
The Elric brothers gave the Doctor a strange look.
"What do you mean?" Alphonse asked.
"There is a dangerous fate approaching Amestris and the whole world, especially when the country is in the shape it is in." the Doctor whispered mysteriously, sadness in his eyes. "You two must be prepared to save the day, although sacrifices must be made. Remember, Equivalent Exchange can only be fulfilled when you have the Truth is within reach once more - "
"What the hell are you talking about? Who are you?" Edward exclaimed. This man was more than what he appeared to be...like someone ancient, with infinite wisdom...
"This man is like old Hohenheim!" the brothers recognized.
"I told you, I`m the Doctor! Oh, should really going, my presence could potentially attract some...unwanted little thingys." the Doctor smiled cheerfully. "One last thing, promise me to not tell anyone else about me, I really don`t belong around here...tally-ho!" With this, the lunatic began to make his departure.
"We promise." Alphonse hastily answered, hoping that this would cause the man to stay for a little longer. Edward`s response, on the other hand, was quite something else.
"Hey! You`re coming with us!" Edward yelled, using his hands to perform alchemy.
The Doctor whirled around, pressing the button on a flashlight-like object he pulled out of his pocket when a massive stone hand burst out of the ground to reach for him. The flashlight object emitted a high-frequency sound for the stone hand instantly disintegrated onto the ground.
"What was that?!" Edward exclaimed bewilderingly at the Doctor.
"It is, Edward, the creation of a sound frequency with temporal resonance aftereffects, making your stone-construct fall apart. When you`re a multiversal time-traveler, you always have to have a escape plan, you know!"
Alphonse blinked at this strange answer. "You`re basically...a Time Alchemist?"
"I suppose you can call me it, although I don`t really use alchemy. I used advanced technology instead!" the Doctor exclaimed, slowly withdrawing back.
"You`re still coming with us, mister!" Edward glared, slowly advancing forward.
"I think not, Mr. Elric. I already told you I don`t really belong around. Basically...auf Wiedersehen!" the Doctor turned around and ran away.
"You come back here!" Edward screamed.
Alphonse sighed to run after his brother.
It was midnight.
After a long battle with Edward and Alphonse making a miniature alchemic war against the Doctor who defended himself, much of East City was destroyed. In the end, the Elric brothers finally cornered the Doctor on a rooftop.
The man looked quite calm before looking up for a moment at the crescent moon. "Blimey...we could have settled this with a cup of jelly babies instead. Look at my overcoat!" The Doctor glared at his scratch-covered overcoat. "Another one ruined... Oh, I`m beginning to like the lovely-sounding nickname you gave me, the Time Alchemist..." the Doctor slowly retreated away towards a blue box the Elrics had not noticed before.
"You...I`m going to capture you when it`s the last thing I do!" Edward screamed, smirking like a madman.
"Brother, we did promise to not tell anyone." Alphonse reminded him.
The Elric brothers looked at the lunatic of a madman, only to see him step into the blue box. "After him!"
The brothers leaped at the man, only to smash into what appeared to be an invisible wall.
"The Tardis projected a force field to protect me. You could attack all night long." the Doctor explained, opening the box`s door. The Elric brothers gasped. The box was bigger on the inside! "Remember what I mentioned earlier. I will be secretly watching from the shadows. Good luck!
"Doctor...who are you?" Alphonse muttered.
"...Doctor who?" Edward asked too.
"My name is not Doctor Who. I am the Doctor!" the Doctor smirked, then he entered the blue box.
The 'Tardis' disappeared in the Elric brothers` eyes.
Time Alchemist indeed...
