Knull

Knull is a fictional character appearing in American comic books published by Marvel Comics. He is a primordial deity of the abyss and the creator of the Symbiotes. Knull's origins trace back to the void that existed before the creation of the Marvel Universe. He wields a living, sentient blade of darkness called All-Black the Necrosword, which is the first Symbiote and the progenitor of all others.

Knull's motivations are typically focused on consuming and corrupting all life, returning the universe to its primordial, dark state. He views creation as an affront to his existence and seeks to extinguish all light and life. His powers are vast, encompassing control over the Symbiotes, the ability to manipulate darkness and shadow, and immense physical strength. He can also create and control armies of Symbiotes, shaping them into various forms and weapons.

His first significant appearance was in Venom vol. 4 #1 in 2018, though his existence and influence were hinted at in earlier stories. Knull has been a major antagonist, particularly for the character Venom, and has played a pivotal role in major comic book events such as "King in Black." His ultimate goal is to plunge the entire Marvel Universe back into eternal darkness.
