Anti-Venom is a fictional antihero appearing in comic books published by Marvel Comics. He first appeared in The Amazing Spider-Man #569 (August 2008), and was created by Dan Slott and John Romita Jr. Anti-Venom belongs to a race of amorphous extraterrestrial parasites known as the Symbiotes and is regarded as Venoms symbiotic brother. Unlike most of the other symbiotes, Anti-Venom isn’t necessarily a relative or descendant of Venom. Instead, hes shown to be a modified form of the original symbiote.
Anti-Venoms physical features include white "skin", a black face, and a spider symbol across his chest. He has superhuman strength, and before the symbiote was created, Eddie Brock had conditioned himself to lift (press) 700 lb_(Earth-616)). Once the symbiote was created, it added Spider-Mans powers to Brocks own_(Earth-616)). Anti-Venom has the gift of genetic memory, which allows him to carry vast amounts of knowledge regarding not just his host but anyone he physically touches. With just a single touch, Anti-Venom can draw on the memories of those around him, their experiences, and their lives.
Anti-Venoms situational awareness is basically a better form of Spider-Mans spider-sense. While the ability itself may be similar to Spider-Man’s spider-sense, Anti-Venom’s is far more powerful. In some cases, Anti-Venom could go so far as to "cure" superhumans of their superpowers, which was almost the case with Spider-Man. The web-slinger was always at risk of losing his powerful abilities when he fought against Anti-Venom, resulting in a few difficult battles. Anti-Venoms unique effect on Spider-Mans powers acts as a spider repellent.
