I'm not entirely sure as it might be a relatively unknown or specialized graphic novel. It could potentially be about a unique character named Knull. Maybe it involves a dark and mysterious story given the name's sound.
I'm not well - informed about this specific 'knull graphic novel'. However, typically in a graphic novel, the main characters are those who drive the story forward. So, apart from Knull (if it is indeed about him), there could be other characters like a hero who opposes Knull or sidekicks who help or hinder his plans.
One key element is the creation by Knull. He made the symbiotes. For Venom, the key is its bond with Eddie Brock. Also, the symbiote's arrival on Earth is important.
The origin story of Venom and Knull is quite fascinating. Venom, as we know, is a result of an alien symbiote. This symbiote was part of a species created by Knull. Knull was an all - powerful being in a distant and dark corner of the universe. He had the ability to create these symbiotic organisms. The symbiote that became Venom was one of those that eventually made its way to Earth. It first had interactions with Spider - Man which were not so smooth. Then it found Eddie Brock, who became the well - known Venom. Knull's influence on the symbiotes is a major part of the overall story, as his dark nature is somewhat imprinted on the symbiotes, even as they evolve and change over time.
The Avengers originated in Marvel Comics. Marvel has developed a vast universe of characters and storylines, and the Avengers are a key part of it. Their adventures have been adapted into various forms of media, including movies and TV shows.
Captain Marvel is Carol Danvers. She gained her powers through an interaction with alien technology and has become a powerful hero in the Marvel universe.
Marvel justifies Marvel Comics 1000 by presenting it as a celebration of their rich history and a platform to introduce fresh and exciting story arcs. It could also be a strategic move to attract new readers and reignite the passion of long-time fans.
