PARIS, FRANCE, 14:20

Multiple high-tech equipments and machinery were built in the huge Catacombs under the city of Paris, the men and women working in those equipments wore green and yellow uniforms with skull like helmets. The bigger area of the catacombs was turned into a throne room of some sorts, sat on the throne was man with a face that resembled a red skull, he wore a black leather trench coat, black gloves and black boots, above him was the banner of his organization, a skull with six octopus tentacles.

That man was Johann Schmidt, better known was the Red Skull, one of the leaders of the Terrorist Organization HYDRA. By his side was his bodyguard, a tall and muscular man who wore a black and white skull like mask, a black sleeveless shirt, black fingerless gloves, green camouflage pants, a brown belt with ammo bags and soldier boots, he was Brock Runlow also known as the mercenary Crossbones. "Crossbones, report our progress." The Red Skull said.

"Yes, boss. We contacted The Hand in Japan, as well as Count Nefaria Leader of the Maggia, they were more than willing to assist us, I also talked with your old acquaintance the Soviet General Aleksander Lukin, he seemed a little resistant about working with us. I gave him a deadline to think about it." Crossbones said.

Red Skull growled in annoyance. "This is barely a quarter of the military power I need. To defeat my rivals and acquire full control of HYDRA , I'll need more than that." Currently HYDRA was under a Civil War of sorts, the organization was divided in four splinter factions. One was lead by Baron Wolfgang Von Strucker, as additional forces other than the HYDRA soldiers he had his bodyguard the Grim Reaper, and the support of the organization A.I.M. The other faction was lead by Baron Hemult Zemo, other than having an army of HYDRA Soldiers he also had his own group of Supervillains, the Masters of Evil. And Viper, also known as Madame HYDRA, along with having the normal HYDRA forces she had the support of her husband and Yakuza leader the Silver Samurai and the Serpent Society.

"I know, boss. But understand, it is hard to find people that are willing to assist you." Crossbones explained.

"I, see. Good thing that I asked Dr Zola to work on a sub-project, as a guarantee." Red Skull said and he got up from his throne. "Crossbones, could you please follow me?" They walked through the corridors of the catacombs until they arrived at a laboratory, there they found a man who wore an orange and purple suit with camera in the place of his head and there was a holographic image of his face in his chest, working on a giant ring like machine, that man was Dr Arnim Zola, the head scientist of HYDRA. "Dr Zola."

"Oh, Herr Schmidt, good to see you here, I was just finishing the last details." Zola said.

Crossbones raised an eyebrow in doubt. "And what is this trinket, doc?"

"This "trinket" is a trans-dimensional portal." Zola said in an annoyed tone as he kept working on the portal.

"This is an attempt to recreate the same experiment that I did during WWII. By that time I had transported creatures from the Nine Realms of Nordic Mythology to gather an army, of course it could have been a success if wasn't for the interference of Captain America and his partner Bucky Barnes."

Zola pressed a few buttons and then the portal flashed and opened a black vortex. "Herr Schmidt! The portal! It worked!"

"Good job Zola." The Red Skull said shaking Zola's hand.

Crossbones crossed his arms and he leaned forwards to the portal. "But where is this thing will take us to? Shouldn't be better to do some sort of test to see if it is safe?"

"Do you think so?" Zola said.

Crossbones shrugged. "I am not into science doc. But you can be damn sure I won't cross a portal with the danger of being split in half."

Zola activated a flying drone with a camera and he made it cross the portal, through a computer they could see what the drone was seeing. The drone had arrived at a seemingly never-ending white desert, with a multitude of dunes, littered with boulders. The sky was black like the night with a shining full moon. "What is this world?" Red Skull said.

"It is not the first time I've seen this place, I've been studying this world and its inhabitants for a long time." Zola said.

"Wait, something is near the drone." Crossbones said, pointing at the screen.

A gray-skinned slim and muscular humanoid walked towards the camera. As it came closer, more of its features were visible, the creature had a hole in its chest and its face was covered by by a white skull like mask with six eyes.

"What am I looking at?" Crossbones said.

"At the foundation of our new army." The Red Skull said. The six-eyed creature crushed the camera with its bare hands.

SOME TIME LATER

The Red Skull and Crossbones had gathered a handful of HYDRA soldiers, they were yielding special weapons made by Zola. "Now men, our mission is to go to that world and capture the creatures there." Red Skull said.

"Doc built these guns to paralyze the creatures, we don't know what is in there so stay sharp, the smallest mistake can be your last." Crossbones said.

"All soldiers move out!" Red Skull said and he crossed the portal.

"You heard the boss, move out!" Crossbones said, he and the soldiers crossed the portal, they found the Skull there, in that nightly desert place. "So boss, how are we going to find those creatures?"

"Remember, Arnim Zola has been studying this world and its inhabitants for a long time. He discovered that those creatures feed on souls." The Red Skull said and he showed to Crossbones a metal disc with a circle of blue crystal in the middle. "He gave me this to bait the creatures." He crushed the disc and then threw it at the ground, and then the disc started to expel a white smoke like energy. "The bait will stay active for only a few seconds, but it surely will attract a lot of attention, be on your guard men!"

Six tentacles burst out of the sand and grabbed one of the soldiers, then a creature that resembled an octopus with a dinosaur like head. Just like with the six-eyed creature, this one had a white skull like mask. The captured soldier panicked and tried to shot the creature but he missed all the shots and he ended up being eaten alive whole. The Red Skull rolled his eyes and then he shot the creature that fell unconscious on the ground with energy rings surrounding its body. Then more creatures appeared they all looked hungry.

The bigger monsters, were 6 stories tall, easily dwarfing the other creatures, with white masks with an elongated nose. Their bodies were covered from their head to their feet with a black covering reminiscent of a cloak. Around their neck is a row of thin white spikes. They had large, pointed feet wrapped in white bandages. "Sir, we are surrounded! They outnumber us in 22:1!" One of the soldiers said.

"22:1? These odds show a very low chance of winning." Crossbones said.

The Red Skull took the paralyzing rifle of the dead soldier and he smirked. "For them! Hail Hydra!" They started to shoot at the monsters that rushed to eat them.

MEANWHILE

Far away in another the desert, stood a large white fortress with the center being a giant dome surrounded by several smaller buildings and towers, on top of the dome were five large towers. Inside the fortress was a laboratory being oversaw by a thing tall man with shoulder length pink hair and amber eyes. He wore a long shirt that covers his entire torso up to the top of his neck. He had three stripes on his uniform, each starting at his collar with two running to each side of his chest and one down the middle, regular pants with a slight length taken away, and white gloves, he also had white rectangular glasses that gave him a scholarly appearance. That man was Szayel Aporro Granz, the 8th Espada, and he had a displeased look as he kept watching the screen of his computers. "These humans are way more dangerous than what I would expect." Szayel leaned forwards, his eyes narrowed. "But why are they capturing the Hollows?"

"This is something I'll discover by myself." Szayel widened his eyes in surprise.

"Lord Aizen?"

WITH THE HYDRA FORCES

The bait's effect has wore off. Of the 21 soldiers sent, 15 were dead, but nonetheless, their mission was a success. The creatures have been captured in a large quantity, and now they were being transported through the portal. "Hey boss, about the big ones. How are we going to transport them? I mean they are too big for our base." Crossbones said.

"You are right, Crossbones." The Red Skull pressed a few buttons and in his rifle then he shot the five giant monsters in the head, killing them. "Problem solved. Now finish taking these creatures through the portal." He grabbed one of the monsters by the face and then threw it through the portal.

Crossbones helped the soldiers transport the creatures. The soldiers left first to assist Zola, Crossbones and the Red Skull were about to leave until the mercenary stopped walking and he looked through the corner of his eyes. "Hey, boss."

"I know." The Skull and Crossbones quickly turned and they shot at a man that had recently arrived, but in vain for the man deflected the shots with a few swings of his sword, that was a katana with a hexagon shaped guard. The man was slim and tall with swept back brown hair and brown eyes, and he wore a white coat over a black hakama.

"Interesting weaponry you have, it made you capable of capturing those Hollows. Still, to shoot me, you have quite a nerve for a mere human." The brown haired man said.

"Mere human?! Who do you think you are talking to?! I am the future ruler of mankind!" The Red Skull snarled and he aimed and shot at the brown haired man this time killing me. "So much from someone supposedly better than me." The Skull scoffed.

"Shatter, Kyoka Suigetsu." Then the man's corpse broke into the sword he was previously using, Crossbones and the Red Skull widened their eyes in shock, the later turned and tried to shoot but both his rifles ended up destroyed.

The brown-haired man disappeared and reappeared to take his sword. Crossbones tried to shoot but his rifle ended up cut in half. "What the hell, just happened? I saw you gunning him down, boss."

The Red Skull dashed towards the man and tried to punch him while evading the man sword's swings, the man tried to stab the Skull in the face, but he ended up being kicked in the head and launched towards a rock. "That is what I am trying to discover."

"It is the power of Complete Hypnosis generated by my Zanpakuto, Kyoka Suigetsu. It controls the five senses to the point that it can make the target misinterpret another person's shape, size, feel, mass, smell and sound." The man said.

"It is obvious that you are not human. Who and what are you?" The Red Skull said.

"I am Sosuke Aizen, a Shinigami and Former-Captain of the 5th Squad." The man said.

"Former-Captain? So I am talking to a military. I am Johann Schmidt, of the organization HYDRA. This is my bodyguard, Crossbones." The Red Skull said.

"HYDRA? So you must be the famous Red Skull." Aizen said.

Crossbones gulped, and Schmidt's right eye twitched as he showed a smile filled with venom. "So, I am known even in places out of Earth."

"Of course, HYDRA has quite a reputation, even in Soul Society." Aizen said.

"Soul Society, this is the place we are in?" The Red Skull said.

"No, this place we are is called Hueco Mundo, the home place of the Hollows, the creatures that you captured moments ago." Aizen said.

"It seems that we could learn a lot with each other." The Red Skull said, and he crossed his arms. "Your abilities impressed me."

"Indeed, you are far from an ordinary human." Aizen said, and then he grinned. "How about we make a deal?"

"I am listening." The Red Skull turned to Aizen.

"I would aid you in conquer Earth, and in exchange you assist me in taking over Soul Society." Aizen said.

"Very well then, help me destroy my competition for HYDRA's leadership and take over Earth and I'll help conquer whatever place you want." The Red Skull said. "As long as you stay out of my way." He gestured to the gun holster in his right hip.

"The same to you." Aizen said, the Skull chuckled and then they shook hands.

MEANWHILE

Arnim Zola and the other scientist were putting electronic collars in the Hollows, in order to control them. Until the head-scientist was distracted by Red Skull and Crossbones crossing the portal, the former having a huge smirk in his face. "Good that you are back, Herr Schmidt." Arnim said.

"I am thankful for your concern doc." Crossbones grumbled and he left the laboratory, his hands in the back of his head.

"You look happy Herr Schmidt. Did you find any new specimen for me?" Arnim said.

"Even better, Dr Zola. I found the support that I needed. Soon, HYDRA will control the world, with me as its leader."
