Eddie Brock
On January 28, 2011, the identity of "black ops" Venom was revealed to be Flash Thompson. Flash is hired by the government to be a special agent wearing the Venom symbiote as part of Project Rebirth. Flash is only allowed to wear the suit for up to 48 hours, or risk a permanent bonding with the symbiote.
Eddie Brock is a journalist, a former investigative reporter, and the current host of the extraterrestrial symbiote Venom.
Diego would later be killed by a powerless Eddie Brock, when the latter was eliminating the "evil" of the symbiotes from the Earth. The character was introduced as the fusion of four symbiotes (Lasher, Phage, Agony and Riot), bonded to prison guard Scott Washington.
Cletus Cortland Kasady is a supervillain appearing in American comic books published by Marvel Comics. Created by writer David Michelinie and artist Erik Larsen, the character first appeared in The Amazing Spider-Man #344 (March 1991) as the first and most infamous host of the Carnage symbiote, an offspring of Venom.
It could be that in the universe of the Venom movies, this type of strong bond is already known among the symbiotes to result in stronger specimens. This could explain why Venom is so fearful of facing an enemy with a ruddy hue.
Originating as an offspring of Venom, Carnage is much more powerful than its parent symbiote because of the symbiotes' biology, and is in many ways a darker version of him.
The son of Carnage, Toxin, was believed to be the most powerful symbiote ever created. The raw power of Toxin was so great that he was feared even by the King in Black, Knull, creator and leader of the symbiotes.
Early on in his career as a "lethal protector," Venom was captured by Carlton Drake's Life Foundation and had five samples of his costume taken and turned into new symbiotes. Four of those symbiotes - Riot, Lasher, Phage and Agony - are grouped together here.
Disgraced and suicidal with a growing irrational hatred for Spider-Man, Brock comes into contact with an alien symbiote, rejected by Peter Parker. The symbiote bonds with him and they become Venom, together seeking out revenge against their mutual enemy.
Dylan Brock is the son of Eddie Brock and Anne Weying. When Anne bonded to the Venom symbiote, she somehow became pregnant with Dylan. He was created by the symbiotes in order to destroy their god Knull and sever him from the hive-mind.
Venom says it's because Eddie has shown him how much fun it is on Earth and he wants to continue enjoying it, which he certainly can't do if the Symbiotes invade, eat everyone, and destroy the world as we know it.
This is because Carnage is the spawn of Venom and each new evolution is stronger than the last. On top of that, Carnage's choice of host, Cletus Kasady, makes for a deadly blend as Carnage and Kasady play on each other's killer cravings and aren't afraid of a murderous rampage or two.
Topher Grace also played Eddie Brock, a Daily Bugle employee that quickly becomes Peter Parker's rival, in Spider-Man 3. After detaching from Peter, the alien symbiote collectively known as Venom chooses Eddie as its new host.
While Eddie Brock's Venom may not be the strongest here, he is recognizable and the most resilient Symbiote compared to many others. Even though he started out as a pure villain, Brock's Venom showed many heroic traits.
The red hue and unstable, fluid-like design of the character is meant to represent its fusion with Kasady's blood. This strange connection to the color red and its association with blood goes well beyond Carnage's origins.
His symbiote is corrupted and evolved, making Carnage even stronger than both Venom and Spider-Man.
Birth. Born from Carnage as the 1000th symbiote in its lineage, "Toxin" was feared to be the strongest and most dangerous of their race by both Carnage and Venom besides Knull. Shortly after being born, the symbiote united with police officer Pat Mulligan.
While in prison, Venom produces an offspring named Carnage. (He reproduces asexually, in case you were wondering.) Venom doesn't tell Eddie about it, and Venom and Eddie escape prison. Once they're gone, Carnage bonds with Cletus.
While captive, the Venom symbiote was forced to give birth to five offspring - Riot, Lasher, Phage, Agony, and Scream - who were bonded to PMCs hired by the Life Foundation. When corrupt corporation Scarmore Inc.
Following it giving birth to Toxin, Cletus began affectionately referring to the Carnage symbiote using female pronouns. He has more recently reverted to referring to it with male pronouns.
