In the design of Marvel comics, venom first appeared in the comic "Magic Spider-Man". It is a living and thoughtful alien life, which usually exists in liquid form and must be parasitic on the host (usually human) to survive. After parasitism (in fact, it should be said that it is superficial possession), it can give the host great strength and ability, which will be worse for good people and worse for bad people. Venom is a famous villain in Marvel comics and Spider-Man's sworn enemy, also known as the poisonous spider (because it once parasitized Spider-Man, it has most of Spider-Man's abilities).

When it comes to the relationship between Spider-Man and venom, it's really messy. Venom parasitized Deadpool at first, but Deadpool noticed that * * * was conscious, so he took off * * * and gave it to Spider-Man, but * * * has inherited the dark side of Deadpool's personality. After parasitizing Spider-Man, the little spider darkened, and then the little spider wanted to escape with the help of the church bell.

Fortunately, * * * learned to understand other people's feelings after parasitizing the spider and left the spider on his own initiative. At this point, * * * was dying and had to find a host. When he fell into the church, Eddie Brock, a journalist who lost his job because of Spider-Man, was there, and then infected Eddie, the most famous poison.

Venom once became Spider-Man's sworn enemy, and most of its abilities came from Spider-Man, which can be described as mutual love and mutual killing.
