I'm just going to go ahead and agree with Chewy on this one, and assume you've never actually read anything at all about Ultron before.
Ultron is *not* a garden-variety killer robot. His menace comes from his motive and personality, which are linked directly
to Dr. Henry Pym. Pym inadvertently gave his creation an Oedipus complex, and Ultron's primary motive over the course of his entire sordid career has been to kill his daddy (his creator) Hank and mate with his mommy, Janet Van Dyne. There is absolutely no other way to tell this story
without Hank Pym and Janet Van Dyne. Period.
