  • Ultron is similar to Sigma, that they are robotic supervillains who despise humans and have spare bodies for their minds to inhabit if their current ones are destroyed.
  • His description of Tony Stark as a "sickness" in Avengers: Age of Ultron would finally be fulfilled through the latter's characterization in Marvel VS Super Sentai.
