Aku

Aku Born from The Black Mass of Darkness, Aku was an evil, shapeshifting demon who took over the world and ruled it for countless eons, the arch-nemesis of Samurai Jack and his father, the Emperor as well the biological mother of Ashi and her septuplet sisters

Long ago in the vastness of space, a great, formless, mindless entity of evil arose. Before it could do harm to the universe, it was set upon by three deities, each one originating from Norse, Egyptian, and Hindu mythologies: Odin (the father of Thor), Ra (the Sun God), and Rama (the seventh avatar of Vishnu the preserver). The three deities fought a fierce battle against the Black Mass and burned the entity almost completely out of existence with their divine power. However, during the battle, one small fragment of the entity was incidentally cut from the whole by Odin and was never burned away. Unnoticed by the three deities, that seemingly small fragment floated away from the site of the battle and drifted through space for an untold amount of time, until it eventually, and violently, crashed on Earth during the Cretaceous Period in the Mesozoic Era. It was implied that the fragment of the black mass is the very object that caused the extinction of the dinosaurs, although the crash occurred in prehistoric Japan as opposed to the Yucatán Peninsula by a massive asteroid. Unexpectedly, the poison arrow's magic had the unforeseen effect of galvanizing the evil mass into a humanoid form: it gave it intelligence, sentience, and shapeshifting abilities. This entity proclaimed itself with the name of Aku and thanked the Emperor for inadvertently helping him. The Emperor then attacked Aku, but with nothing more than his mundane and mortal weapons, he couldn't inflict any harm upon Aku. Aku then easily defeated the Emperor and strapped him to the side of a tree so that he could watch as Aku began destroying his kingdom and slaughtering his people. However, the Deities, after they sensed the good in the Emperor summoned him with the aid of Odin's horse, Sleipnir. After the Deities took the good from inside the Emperor they then used their powers in creating an Enchanted Sword that was capable of harming Aku. After he was armed with the sword and a magical suit of armor, the Emperor plunged into battle against Aku. In the end, the Emperor was victorious and imprisoned Aku into the devastated wasteland in the form of a jagged black tree. As he was sealed away, Aku vowed that he would one day return. During the battle, The Empress gave birth to a son. After he was determined to learn from the catastrophe and was aware that Aku would indeed one day return, the Emperor hatched a plan while orchestrating the events that would set Jack on his eventual years of training.

Return

Eight years later, during a solar eclipse, the seal that the Emperor placed on him broke and Aku was released. Aku's first target was the village of the Emperor who sealed him away eight years prior. In a castle, Jack was a young child and his father told him the tale of how he defeated Aku. After the story was done, Jack was left alone, and played with a toy sword. Suddenly, the castle was covered in Aku's shadow. Aku then unleashed a vicious attack on the village. The Emperor then attempted to grab the sword, but Aku captured him before he could reach it. The Emperor told the Empress that it was time to enact the plan they had prepared for. Following the plan, Jack's mother escaped with Jack and the sword. Jack then started on a journey to prepare him both physically and mentally for his confrontation against Aku.

Abilities: Near-Immortality: As a supernatural being, Aku was ageless and nearly immortal. She required no sustenance and was not harmed by mortal means. Only the power of righteous spirits or divine weapons like Jack's Sword, or divine entities, were capable of doing severe harm to her Voice Mimicry: Even when she didn't shapeshift, Aku could still change her voice in her natural form. Supernatural Physical Abilities: Aku could alter her physical capabilities to virtually any level that she needed or wanted due to her magical shapeshifting abilities. Aku manifested superhuman strength, speed, endurance, and senses. No parameters or upper limits were established that regarded those capabilities. Regeneration: While Aku was completely resistant to most forms of attack, she was not invulnerable; items such as Jack's Sword or magic such as divine energy could damage the substance from which he was made of. However, Aku was able to regenerate to a large degree, even against attacks such as those. These sort of assaults tended to create large, burning holes or gashes in Aku wherever she was struck, which she could close back up with effort. However, his ability to regenerate in those situations was limited. In many of Aku's confrontations with Jack, the damage that was caused by the sword whittled away at her overall mass and her ability to regenerate in the short term, until it tended to leave her as a very small animal of some sort, such as a frog or a mouse, at which point further attacks would have presumably either sealed him away as Jack's father did, or killed him as Jack intended to. Given time however, Aku always restored himself without being any worse for wear. Aku was also observed to succumb to physical pain that involved blunt trauma of equal mass in relevance to the size of his form at any given time, although she was shown to quickly recover from such injuries. Dark Magic: Aku was an all-powerful wizard who had vast supernatural powers at her command. Eye Beams: One of Aku's most commonly utilized attacks, that ability tended to manifest as beams of white or red light that typically incinerated the objects that it made contact with. It could be used either as continuous beams of light, or as staccato bolts of energy. Aku had used that ability in numerous battles with Jack, and also used it to destroy the majority of Jack's past kingdom. Aku could also harmlessly teleport beings to places of his choosing through that power. The beams could also slice through objects like a plasma torch or caused them to explode. Aku also used a variation of that ability to restore or recreate whatever she chose, such as when he restored Scaramouche's body with them. Remote Viewing: Using mystical forces in her lair, Aku could create images on the walls in order to view whatever he wished. Aku tended to use that ability to simply watch Jack travel while he stewed in his unhappiness at being unable to kill Jack. Teleportation: Aku used that often for quick appearances or escapes, and to appear before those that he had business with, such as the Imakandi. Elemental Control: Aku could magically project and control the elements of the physical world. Those abilities included breathing and projecting streams of fire from her body, manipulating the earth itself, conjuring thunderstorms at will, or emitting waves of sonic force. By combining fire breath with his eye beams, Aku could also project beams of electricity. Necromancy: Aku was shown to be capable of animating countless dead bodies and bending them to her commanding will. Precognitive Dreams: On one occasion, Aku was shown to be capable of receiving premonitions of her own future through her dreams, which he could then act upon to try and prevent or change them. Possession & Infection: Aku could use small portions of himself to infect others with his evil. The only time that this was seen was when she incidentally spat up a tiny portion of herself at Jack, which, over the course of a day or so, possessed the samurai and gave him an appearance and personality similar to her. On a related note, Aku could also use portions of herself to give power to machinery, as she demonstrated by doing so with the Ultra-Robots. That ability could also work on Aku's biological offspring, since they already had his essence and were a part of her. Interstellar Travel: Aku was capable of interstellar travel, well beyond the speed of light. Time Travel: That was the very ability that Aku had used that sent Jack into the future at the beginning of the series, though she only used that once and it was a one-way portal forward in time. However, due to its side-effect, Jack did not age even after 50 years in the future. Life Creation: Through unholy arts or her own essence or fragment thereof such as her dark blood Aku can deliberately create life alone or by reproducing with other life forms such as Ashi's mother, the High Priestess, who drank her blood and became pregnant with seven daughters. Object Materialization: The ability to create matter and materials out of nothing, Aku once used this ability to conjure treasures in the presence of the Imakandi. Aku also used her eye beams and created a new body for Scaramouche. Corruption & Mutation: One of Aku's most powerful abilities. Using dark magic, Aku could mutate normally harmless beings into monstrous, corrupted versions of themselves. During her last known encounter with Jack, Aku used this ability to transform three small rams into monsters in order to fight Jack. It was also shown that if the corrupted creature died, the spell was broken, reverting them back to their original forms. Combat Skills: Despite never having been shown to have trained at all in any form of Martial Arts, Aku was a very skilled practitioner in hand-to-hand combat. Though not a match for Jack, Aku was at least capable of defending herself reasonably well against Jack during their duel, while he limited himself to human physicality. Aku was also shown to be a fairly skilled swordsman.

Appearance: Aku takes the Apperance of a dark skin woman having red eyes with long dark hair with four black horns having a voluptuous body having massive breasts with large thick thighs wearing a Japanese traditional kimono color fully black with a red band around her waist also showing off her massive cleavage
