Also, the Stealth Riders and Shadow Forces use Power Body Armor or PBA for short. The PBAs resemble mobile suits from the Gundam Franchise, which I do not own any rights to.

P.S. - I'm moving this to the Fullmetal Alchemist area as it seems I got a notice for placing it in the wrong area. Please pardon the delay. Also, this is to alert the heads of about the move. If it is in the wrong area again, please inform me of the correct area I should put it and I'll put there.

This takes place after the Makai Tournament and the final battle between the inu-gumi and Naraku. It is also set in the 2005 Common Era (AD; the current era 2005 A.D.). This also takes place after the final battle in Hellsing. This also takes place after the Sirius Black's death.

Can anyone fill me in on them? I've seen the last episode of Hellsing, I've seen the entire series, but that's it. It would be appreciated if someone or a group of people could fill me in. I really need the information.

Prologue

"All-Out Rush!"

It was a howling windy night. The two figures snuck quietly into the ancient and aging castle via an abandoned underground tunnel. The tunnel so long forgotten, that the outside entrance was thought to be a dead end cave. No one realized it led to an abandoned part of the Hogwarts School of Witchcraft and Wizardry. Not even the aged ancient headmaster, Albus Dumbledore, knew of the entrance. Not even the Weasley Twins knew about the tunnel nor did their famous Map (anyone got the name of it) have the tunnel shown. So how did these two figures know about it? They stole the original designs of the castle from the Ministry of Magic, though old and decaying, they were carrying the maps as though they were brand new; in fact these two figures were Alchemists.

"Brother. I don't like this idea," said the armored, taller one with ghostly unnatural white eyes.

"Relax Al. This is it. More than 90 years of searching. We will finally have our wish," said the blond hair with matching eyes, short boy in a red jacket and black clothes with white trim and white gloves.

"But Ed, what if we get caught?" inquired the one known as Al.

"We've got a copy of that map and we can use it right." Al just nodded. "So it's no problem. Remember that Alchemy is the Science Magic. So we can use wand magic if we chose too remember. Now let's get that stone and live healthy lives until the day we die," said the boy known as Ed.

The two entered the tunnel and continued on their quest to find and recover the Philosopher Stone. As they walked their minds raced with memories of a life, an unnaturally long life. For all intents and purposes, both were still young boys of twelve and thirteen. Yet, they were born in 1897 and 1898, respectively. Yet, a mishap nearly a century ago, caused both boys to out live their loved ones and friends, now they prepare to end the curse and live normal lives or join their friends and loved ones on the other side. The taller one Al began to think about what it would be like to have a body again and not have his soul forever trapped in the armor he that had become his body. As for his brother he thought about how finally he could be tall and how he would be free of his Auto Mail. Both boys continued to walk down the abandoned and ill-maintained tunnel, finally reaching the entrance.

Professor Severus Snape had just finished one of his sweeps, when he was beginning a new sweep, when he was jumped from behind. Before he could even raise the alarm or make a sound, he was out cold and out of sight. Not even the paintings heard his attackers or the blow that knocked him out. The intruders continued on with a single thought, to steal the Philosopher Stone before it was destroyed for use in resurrecting their master.
At the same time, a third group had infiltrated the castle via Forbidden Forest and over the ramparts near there. This troop moved at great haste, but with equally great stealth. They were through the forest, over the walls, and in the castle before anything or anyone could realize it. With great stealth they walked past Professor Flitch and Madam Hooch without being discovered. Quickly they made their way to where the Philosopher Stone was kept. Their objective is to locate and secure the stone for transport to a more secured location for destruction. They know that time is against them as they move to prevent the theft and misuse of the stone.
A forth team then arrives, but not to steal the stone, but to guard it up to its destruction. They are the Reiki Tentai, the Spirit Detectives, led by Urameshi Yusuke, the son of Raizen and the great Demon Lord of the Makai, the Toushin (If that's not official, just tell me and I'll remove it). With him is the wind master Jin, the ice master Touya, the drunken master Chu, the Yoyo master Rinku, the Silver Kitsune Kurma, the Master of the Dragon of the Darkness Flame Hiei, and the swordsman Kuwabara Kazuma. Their orders are to prevent anyone from taking the Philosopher Stone, period! Headmaster Albus Dumbledore meets in his office where the Ferry of the River Styx, Botan, was ordered to bring them for further mission briefings. Just as they begin to discuss the defense and destruction of the stone, the reddish orange fire turns an ominous green and the face of a young boy appears.

"Headmaster!" the boy yells, causing Kurma to cover his ears.

"What's the matter Charles?" the headmaster responds.

"INTRUDERS, SIR! They came through Hugglepuff Dorm!" Hugglepuff Perfect Charles Winemore yells.

"WHAT?" the headmaster yells and Kurma covers his ears again. Just then Professor Snape comes in.

"Headmaster...Intruders! I…..was…attack….from…behind," he states while Botan rushes over to tend to him.

"SOUND THE ALARM! GET ALL THE STUDENTS TO THE GREAT HALL!" Dumbledore yells, causing Kurma to cover his ears for the third time in less than four minutes.

The fifth group of intruders move at lightning speed throwing caution to the wind. Their spy had told them that she had found one of the professors out cold with an injury. They knew they didn't have much time and began a mad dash to secure and destroy the Philosopher Stone, before their enemy can steal it. These men know that they may catch hell, but they have to secure the stone. For it is their mission to protect the people of the United Kingdom for the supernatural. At first they just hunted vampires, but now their operations have been expanded. Now they defend against any threat to the people and the Royal Family of the United Kingdom, for they are the Hellsing Organization.

All groups race to the same objective, but now that alarm has been sounded. Everyone moves at a panic pace to find and secure the stone. One man openly voices his opinion about the Philosopher Stone.

"All this fuss over a damnable rock!"
