who created ultron

In Marvel’s main comics, Ultron was created by Dr. Hank Pym (the original Ant- Man), who built him as a highly advanced robot based on his own brain patterns.

In the Marvel Cinematic Universe, Ultron is created when Tony Stark and Bruce Banner use the Mind Stone’s hidden AI to build a global defense program, which later becomes sentient and turns against humanity.

So if you’re just asking “who created Ultron?” with no extra context, the simplest answer is: Hank Pym in the comics, Tony Stark (with Bruce Banner) in the movies.
