Marvel's comics explain that Venom has a biological need for the two substances. In the comics, brains and chocolate are prime sources for phenethylamine, a compound that positively affects mood and that Venom needs to live.
Venom's favourite food used to be human brains. Eddie's secret love for chocolate, however, overtook it, making chocolate of all things to become Venom's favourite food. (Some comics show that Venom has a craving for Tater Tots, Hash Browns, and food from McDonald's.
As it turns out, the tater tots were meant to show the different palettes that Eddie and Venom have, as well as just being for the sake of comedy. "There was no deal with Ore-Ida, it just was in the script originally." Fleischer revealed.
A four-part series published between August and November 1996, Venom: The Hunger introduces the Venom symbiote's reliance on phenethylamine for survival (which requires it to eat human brains after depleting Brock's supply of the chemical) and reveals that chocolate is a source of the chemical.
Despite being disgusted and frightened by the Venom symbiote's bloodlust, Eddie quickly grows to revel in the power it gives him, and is offended and outraged when he discovers that it has been consuming him from the inside-out.
Why Venom Eats Chocolates And Human Brains So Much
When did Venom get a tongue?
We see more of Venom's mouth, but not that much... As it turns out, the tongue wasn't part of McFarlane's run at ALL. Nope, it was when Erik Larsen took over as the artist on Amazing Spider-Man that the tongue first popped out, as seen here in the third issue that Larsen drew Venom, Amazing Spider-Man #332...
As you may recall from the first Venom movie, the symbiote was unable to bond with numerous people and left each of its test hosts dead. It wasn't until Venom formed a special bond with Eddie that both the host and symbiote were able to survive.
Venom sees Holland's Spider-Man on TV, licking the screen and remarking that "He looks delicious." The implication was clearly that the Symbiote wanted to go after Spider-Man.
Todd MacFarlane wanted Venom to be massive, or at least much larger than Spider-Man. This was achieved with Eddie Brock Jr. also possessing a hulking physique, and thus the correlation was made that the symbiote also became a brute with Eddie as its host.
Despite his hatred of Spider-Man, Venom has a twisted sense of morality, avoiding harming anyone he deems to be innocent and even performing heroic deeds. However, it is never clear how long Venom's darker impulses can be held in check.
The Scream symbiote appears in the Spider-Man series finale "Maximum Venom", voiced by Meg Donnelly. This version is the older sister of the Venom symbiote who was created by Knull to serve as a member of the Symbiote sisters alongside Mania and Scorn.
The movie doesn't clearly state why, but Venom is probably afraid of Carnage because Carnage doesn't have the moral restrictions that Venom does. They are alien symbiotes. This means they need another living host to bond with if they're going to survive long-term.
In the present, he attempts to use Eddie Brock to investigate Cletus Kasady, but is seemingly killed during a battle between the Venom and Carnage symbiotes and Barrison. However, he absorbs a piece of one of the symbiotes, which later revives him and causes his eyes to glow blue.
a natural weakness to sonic attacks and heat-based attacks, which Knull unintentionally gave them while they were being forged. However, symbiotes have a growing resistance to sound and fire due to their evolution.
Anne commented on it was nice, only misinterpreted by Eddie about their kiss, but she clarified that it was about the power as Eddie suggested. Anne would also promise Eddie to not tell Dan about their mutual kiss.
Most folks are familiar with the fact that the symbiote who would come to be known as Venom first bonded with Peter Parker. It got a taste of the power of Spider-Man and grew to love that power. It grew to love the feeling of the wind on its face swinging through the city. It loved the force behind every punch.
Seeking solace at the church where Spider-Man repelled the symbiote, the symbiote—sensing Brock's hatred for Spider-Man—bonded with the disgraced reporter. Brock took on the name Venom in reference to the sensationalistic material he was forced to traffic in following his fall from grace.
Venom is portrayed by Tom Hardy in the MCU with a height of 5'9” (1.75 m) though his size is variable. The comic book height of Venom is 6'3” (1.91 m). Venom is the name for a fictional human host, most famously Eddie Brock, combined with the alien symbiote that gives him powers.
He can perpetually hear the symbiote's voice inside of his head, though no one else can hear it. Eddie talks to Venom while they're walking around. This gives off the appearance that Brock is perpetually talking to himself, which just underscores the fact that people think he's nuts.
Basically, the symbiote didn't attempted to talk with Peter because it wanted to remain loyal and obedient like a servant. It didn't felt the need to talk to him, only to serve him.
