After yet another self-upgrade, #Ultron declared himself "the #UltimateUltron" and resolved to destroy not only all human life, but all organic life. To assist him, and to provide him with companionship, Ultron sought to create another mate, killing #Avengers staff Carlos when he got in Ultron's way. Forcing Doctor #Pym and #Adamantium creator Myron MacLain to assist him, and duplicating the brain patterns of Avengers member #Mockingbird to use as a mental template, Ultron created his new mate #Alkhema, nicknamed #WarToy. However, the new couple disagreed on almost everything, most notably how to go about exterminating humanity: Ultron wanted to destroy all organic life instantly if possible, and Alkhema wanted to prolong her enjoyment by gradually killing organics in small numbers rather than wiping them out altogether. Cast into space by the Avengers, the couple returned but soon broke up due to their differing philosophies, and Alkhema helped the Avengers foil Ultron's next attempt to wipe out humanity. Ultron later established a new base in Ottsville, Pennsylvania, gradually converting the townsfolk into part-mechanical beings under his control. Sparrow of the Underground Legion discovered Ultron's base and destroyed his new robotic watchdog, Rex, but Ultron added Sparrow to his army of mechanically altered slaves. Sparrow's Underground Legion teammates-accompanied by Hank Pym-followed her and drove Ultron out, depriving him of his slave army. #characteroftheday #characterbio #bio #marvel
