So then…what horrible event was Dylan born in response to?
From the very beginning, the Cates run of Venom has been building towards the coming of Knull, the God of Symbiotes. AKA the Black King. Retroactively introduced as a godly being from the dawn of time who had taken on the likes of the Silver Surfer and Thor, Knull created the symbiote race itself before being sealed away for countless years. He also created the symbiote-like sword All-Black once wielded by Thor villain Gorr the God-Butcher.
The Venom series notably built to an event called Absolute Carnage, where Carnage was reborn as an extremely powerful harbinger of Knull. Once Carnage was defeated, it was apparent that Knull was free from his prison and is very much on the way.
Now we know that it’s going to at the end of 2020. Knull is coming in King in Black #1 this December.
Fortunately, Venom is on very good terms with Earth’s heroes these days. Thanks to his actions in War of the Realms and Absolute Carnage, the Avengers have even considered maybe letting him join the team. That’s great because they need to listen to his warnings that this damn symbiote god is on the way. Having Thor there to say, “Oh, crap. THAT guy?” is a plus.
