Mission Zero:

The Beginnings of an Assassin, Part One

Darkness. It always began in darkness. And suddenly, there is light, as there always is at the end. Red eyes, stare blankly ahead. These are eyes that seem devoid of emotion or mercy. The creature blinks, it's eyes opening and closing in what seemed to take an eternity. Time was slowing. It would not be long now. The eyes begin to close again. They will close once more, and once they do, they shall never open again. This is both the beginning to our stories, and their end.

Kraken. Assassin to Master Sora, the new King of the Heartless. Kraken was an invisible, but he was also more than that. To truly understand this once black hearted killer, one must trace back to the beginning. How he came to be truly feared by those around him, why his name causes men to quake in fear.as well as his fall from grace, and his end.

Kraken, like all Heartless before and after him, began his existence on the home world of the Heartless. A planet dark, devoid of all natural light. He was a shadow, small and timid, but hungry. Ravenous, for his race craved the hearts of mortals, for they themselves possessed none. Kraken lived life as any heartless did on their world, but this changed when she came. Maleficent. The one they would call Queen. Kraken left his world with his friends and neighbors, travelling to the multiverse of worlds, devouring hearts, destroying the pathetic mortals and their worlds. As he devoured heart after heart. Soon, Kraken began to undergo the same transformation many of his fellows had. He first evolved into one of the new Soldier breed of Heartless. This transformation was amazing to Kraken, he was powerful, he could kill more easily, he need never fear being defeated. He was invincible! This new feeling thrilled Kraken, and as he continued on his journey, stealing the hearts of innocents, he began to grow more violent, more brutal. At times, he would not take the creatures heart at first. He would like to play with his victims, torturing them with his claws, scratching deep wounds into their skin, just to see them bleed. Hear them beg for mercy, plead for help to the silent, dark sky, before tearing their heart, their soul, from their bodies. Sentencing them to an eternal darkness. As he traveled and evolved to the next stages of his existence, he grew more confident. He was Heartless. A creature of infinite power and invulnerable to any and all opponents.

His illusions of immortality and unending victory were shattered one day. At a dark place known as The End of The World.

Kraken stood ready at the entrance to his master Ansem's realm. He was Heartless. An Invisible, strong and invulnerable. His brethren stood beside him. A mighty Angel Star, and two of his fellow Invisibles. They were charged with stopping the one named Sora. Kraken knew no fear. He was Heartless. Invulnerable. Immortal. In the distance he saw them. Three lone figures advancing through the shattered remains of countless worlds. As they approached, Kraken received his first glance of the warrior known as Sora. Kraken was appalled. He was a child. A human child. A human child with a dog and a duck. This was the warrior that had defeated their Queen? These were the warriors that had defeated countless hundreds of thousands of his brethren on countless worlds? This could not be. Kraken flew towards the child and his animals, his comrades close behind. He swung at the child with his sword, and sent the whelp crashing to the ground. Kraken laughed to himself. Pathetic. This child was nothing more then a boy with a toy sword. A fearsome warrior indeed. Kraken's red eyes widened. The boy was standing once more, and instead of tears, or the whimpering sounds of fear, all Kraken found was a cold, fierce determination. A warrior's spirit. For the first time in his existence, the Heartless moved away, for once in his existence, he felt like one of his countless victims. Afraid. Terrified. All too mortal. The boy charged forward and Kraken raced to meet him, determined to regain his lost composure. Regain his lost sense of immortality. He would kill the warrior, and truly be the greatest warrior of all the Heartless! Their blades clashed together. Key against Black steel. Their blades flicked in and out, slashing frantically at one another, but finding not purchase in each other's flesh. But in one instant, Kraken's guard dropped, and a blow was struck. The warrior's blade flicked in a horizontal line across the Heartless' neck, and his black blood flowed freely. He clutched his throat and fell to the ground, flopping about like a fish, plucked from the water and left to die slowly without air. He watched as the warrior and his friends left, his comrades all dead beside him. He slowly crawled to the entrance to the End, and boarded one of the Heartless ships. He kept one hand to his throat, his red eyes now burning more violently then ever before. He would leave the end, find a way to heal himself, then he would return. He would return for his vengeance.
