Var Aku skapad? Om ja, vem skapade honom och gav honom befogenheter?

enligt den wiki du länkade till Aku kom från Black Mass

The Black Mass, also known as The Ultimate Evil, was a non-sapient life form that roamed outer space, and is presumed to have been an organic manifestation of pure evil, perhaps even the source of evil itself. Before it could fulfill its purpose, which was likely to devour all of creation, three deities: Odin, Ra and Rama arrived to exterminate this great evil. The surviving remnant of the Black Mass that escaped the confrontation eventually landed on Earth and would later spawn the demonic sorcerer known as Aku.

Primordial cosmic entity

och i biografin står det

the Black Mass was formed from some sort of explosion that occurred somewhere in the outer space

med tanke på att Primordial betyder "existerande vid eller från tidens början, odödliga". Vi kan antagligen antar att den svarta massan kom från universums ursprung och explosionen var The Big Bang.

Aku visade sig dock bara efter att Jacks far försökte förstöra den svarta massan med en pil belagd i en magisk elixir

Unexpectedly, the poison arrow's magic had the unforeseen effect of galvanizing the evil mass into a humanoid form, giving it intelligence, sentience, and shape-shifting abilities.

så pilarna magiska gav svartmassan den form som vi ser som Aku och det är makt att forma skift.

Så att svara på dina frågor:

• Aku skapades från Black Mass men Black Mass har existerat från början
• Aku skulle ha fått sina befogenheter från svartmassan med undantag av formskiftning som han fick från pilen som försökte förstöra den svarta mässan

Det förklarades i Episode XXXVII: The Evil Birth, del 1

In The Birth of Evil Part 1, the Black Mass was formed from some sort of explosion that occurred somewhere in the outer space. When it set off to find its prey, most likely the universe itself, Odin, Ra, and Vishnu arrived to exterminate the mass. After a fierce battle, the three gods finally defeated the Black Mass. Unfortunately, it was not completely destroyed; a fragment of the black mass drifted away from the battle unobserved and crashed into the Earth approximately 65 million years before the rise of Aku. The subsequent impact is believed to have triggered the Cretaceous-Paleogene extinction period, more commonly known as the event which wiped out the dinosaurs.

As life on Earth began to evolve anew, many people were devoured by the mass as it expanded, likely in an attempt to regain its lost power and essence. When the creature approached Feudal Japan, the Emperor (Samurai Jack's father) attempted to destroy the Black Mass with a magical arrow. However, rather than purging the evil from his land, the arrow's poison instead caused the Black Mass to gain intelligence, self-awareness and consciousness, becoming sapient and being set free from the ancient tar pit. Taking the name Aku.

Så ingen skapade honom med vilseledande, men det händer bara från den återstående rymdenhetens svarta massa.
