Production inconsistencies


  • Spectrum: Scott Lang? What is this?

  • Captain America: What is Nighthawk planning?

  • Black Widow: They need backup now.

  • Nightmare Ultron: You brought me back Stark.
  • Iron Man: Ultron?
  • Nightmare Ultron: The destruction I reaped is in your head.
  • Iron Man: We defeated you!
  • Nightmare Ultron: Did you? Or are you still fighting, in your worst nightmares. And losing.


  • It's interesting to notice that Ultron's voice is very weak and difficult to understand, compared to his other appearances. It may be because he was putten in the sun in "The Ultron Outbreak", probably affected his voice too.


  • It's revealed that Nighthawk and Hyperion forced Dr. Spectrum to destroy the Squadron Supreme's home planet.
