Venom is a fictional character from the Marvel Comics universe, primarily known as an antagonist of Spider-Man.

He is an alien symbiote that requires a host to survive, often bonding with Eddie Brock, a journalist who feels wronged by Spider-Man.

When bonded with Brock, Venom gains enhanced strength, agility, and the ability to produce web-like substances.

Unlike Spider-Man, Venom has a darker and more aggressive personality, often seeking revenge against those who have wronged him.

Despite his villainous nature, Venom has also been portrayed as an anti-hero, sometimes fighting for justice alongside other characters in the Marvel universe.
