    His bonding to a symbiote had also granted him the ability to extend symbiotic tendrils to grasp victims despite his shortened arms. His mutation stunted his inherent intelligence, leaving him in a perpetual state of rage.

History:
(Edge of Spider-Verse III#1) - During a battle between the heroic Spider-Rex and Kravertooth the Hunter in which many bystanders were singing songs of Spider-Rex, Eddie Brockiosaurus witnessed the grumpy Jingshan Jingshanosaurus berating Mary Jane Watsaur for singing about the Spider-Rex "menace" and he told Jingshan to leave the girl alone. Jingshan Jingshanosaurus suggested Brockiosaurus not start arguing himself and warned Brockiosaurus to watch his step around the nearby tar pits, as there was dangerous stuff in the pits. Brockiosaurus scoffed at Jingshan's warnings, commenting that a little splash or two couldn't hurt him but he was soon knocked fully into the tar pits by Spider-Rex, who had been tossed that direction by Kravertooth.

(Marvel Puzzle Quest video game add-on (fb) - BTS) - While stuck in the tar pit, Eddie Brockiosaurus merged with a symbiote living within the pit.

(Edge of Spider-Verse III#1) - Horrified at what he had caused, Spider-Rex rushed to Eddie Brockiosaurus' rescue but Brockiosaurus emerged from the tar pits on his own, mutated into a form resembling a tyrannosaurus rex and craving the taste of brains. The mutated Brockiosaurus hurled Spider-Rex away by his own webbing then used symbiotic tendrils to snatch up nearby dinosaurs in an attempt to devour their brains. Spider-Rex quickly returned to rescue the smaller dinosaurs as Jingshan Jingshanosaurus accused Spider-Rex of knocking Brockiosaurus into the tar pits and transforming him into the newly-dubbed Venomsaurus Rex in the first place. While Spider-Rex was subsequently getting Jingshan Jingshanosaurus to safety, Venomsaurus Rex captured Mary Jane Watsaur and dragged her to a nearby volcano.

    Spider-Rex pursued to rescue Mary Jane and during the subsequent battle, Venomsaurus Rex bit Spider-Rex and knocked him aside. Re-focusing his attention on Mary Jane, Venomsaurus Rex dangled her over the volcano and began to cover her in symbiotic tendrils. Mary Jane attempted to reach her friend Eddie but when she was met only with a loud roar, she admitted her attempt to reach her former friend and bit one of Venomsaurus Rex's tendrils in half to escape his grasp. Spider-Rex rescued the falling Mary Jane Watsaur then teamed up with her to knock Venomsaurus Rex into the volcano.

(Marvel Puzzle Quest video game add-on (fb) - BTS) - Moments later, both Spider-Rex and Venomsaurus Rex were apparently transported from Earth-66 to Earth-13178, where that world's Norman Osborn had caused a war between Earth's heroes and Osborn's villainous cohorts empowered by the powerful Iso-8 isotope.

(Marvel Puzzle Quest video game add-on) - While on Earth-13178, Venomsaurus Rex was briefly empowered by Iso-8 and aided against the heroes assembled to battle Osborn and his allies.

(Death of the Venomverse#5) - Venomsaurus Rex was one of many symbiote hosts summoned to Earth-64926 by Earth-1091's Virus to aid against the godlike Carnage symbiote of Reality-616. Upon arrival, Venomsaurus Rex was almost immediately killed by the Carnage symbiote.

Comments: Created by Karla Pacheco and Pere Perrez.

    Near as I'm able to tell, Venomsaurus Rex might have debuted first chronologically by publication date as an add-on to the Marvel Puzzle Quest video game with his (and Spider-Rex's) characters first appearing in that video game circa late June 2023. However, he technically first appeared in the Edge of Spider-Verse III#1 comic book. You see, Edge of Spider-Verse III#1 might have been cover-dated July, 2023 as the publication but it actually would have been on comic store shelves a few weeks before that, almost certainly prior to his release as an add-on in Marvel Puzzle Quest. Therefore, the character was actually created by Karla Pacheco and Pere Perrez, the creative team on the Edge of Spider-Verse III#1 story despite the date listed in the comic's indicia being July 2023 and the video game add-on debuting in June 2023.

CLARIFICATIONS:
Earth-66's Venomsaurus Rex should be distinguished from:

• V-REX of Earth-76452 - venomized tyrannosaurus rex stuck in a perpetually restarting time loop--Venomverse Reborn#3
  
• VENOM (Eddie Brock) - his Earth-616 counterpart, symbiote-powered lethal protector--Web of Spider-Man I#18
• other "Venomsaurus" or "Rex" characters, groups, races, events or items
