With a pathetic cry of "Aie Aie Aie", Rex exploded. Ultron was furious, wondering, "Why do you garishly clad humans insist on destroying every companion I've ever created?!"
SECRET WARS III HAPPENED
BTS - Rex got repaired.
(A Year of Marvels: August Infinite Comic#1) - Nick Fury Jr. was looking on a lead on a mysterious arms dealer called the Chain. In San Pedro Sula, Honduras Nick Jr. was attacked by Ultron's dog Rex, who was sold second hand to an unidentified operative without the manual.
Comments: Created by Glenn Herdling, Mike Gustovich, and Bill Anderson.
If Ultron used the engrams of Wonder Man to create the Vision, the engrams of the Wasp to create Jocasta, and the engrams of Mockingbird to create Alkhema, which Avenger did he use to create Rex? The Beast?
In Avengers West Coast Annual#6 (1993) Alkhema, after turning on Ultron, suggested to him to build a dog the next time he needed a companion. He was definitely listening to her. Profile by Prime Eternal. Update by Markus Raymond. CLARIFICATIONS: images: (without ads) Appearances:
