Warning! Spoilers for Venom #200 by Marvel Comics below.
Eddie Brock is the new King in Black in the Marvel Universe, and with his new powers, he's become one of the strongest heroes ever. In Venom #200, readers learn what happened to Venom after he defeated Knull, the God of Symbiotes. Eddie has gained some amazing new abilities, which, unlike the previous King in Black, he's using for good around the galaxy.
In Marvel's King in Black event, Venom (and the rest of the universe) was nearly destroyed by the ancient God of Symbiotes, Knull. However, after being killed by the King in Black, Eddie Brock was given the powers of the Enigma Force and turned into the new God of Light. With the powers to counter Knull, a massively upgraded Venom killed his opposite and became the new King in Black himself. In Venom #200, Eddie's life following the showdown is revealed and the former Spider-Man villain has truly become a great hero.
In Venom #200 by Donny Cates, Ryan Stegman, JP Mayer, and Frank Martin, Eddie Brock monologues about becoming the new King in Black. He reveals he can pilot symbiotes across the cosmos through accessing the hive mind and is seen helping a peaceful alien race against a group of conquerors. The comic shows Brock also assisting other people across the galaxy at the same time. In a meeting with Spider-Man, Brock tells his former adversary that he's become omnipresent (like Dr. Manahattan) and can be at multiple places simultaneously. He proves it by talking to Spider-Man, the Avengers, and Silver Surfer all at once, in three different locations.
While his new powers as King in Black are depleting Eddie's real body and making him older and weaker, his abilities have turned him into an incredible hero who can be in different places at the same time. That type of omnipresence mixed with having access to every symbiote makes him truly powerful. Unlike the last King in Black, Brock is using his abilities (and symbiote army) for good and not trying to envelop the galaxy in darkness. He even gives his son Dylan his blessing to become the new Venom, admitting it's the best way to keep him safe.
The good thing about Eddie Brock obtaining God-like powers is he's using them for the right reasons and understands he can't do everything alone. As the new King in Black, the former Venom's insane, universe-spanning powers are helping people, not hurting them. The former villain has been completely reformed and has become Marvel's ultimate hero.
