• The Other Darrin: Lake Bell voices Natasha Romanoff, Mick Wingert voices Tony Stark, Stephanie Panisello voices Betty Ross, Mike McGill voices Thaddeus Ross, and Alexandra Daniels voices Carol Danvers.
• Role Reprise: Technically true for both Lake Bell (she voiced Black Widow in a Robot Chicken skit) and Mick Wingert as Iron Man (though, also The Other Darrin as he'd originally replaced Adrian Pasdar in Avengers Assemble and its sister shows).
• What Could Have Been: According to the documentary series, Marvel Studios: Assembled:
  • Several characters were in the planning stages to appear that ultimately didn't show up. These include Jasper Sitwell, Jane Foster, James Rhodes, Whiplash and Emil Blonsky.
    • Bucky Barnes is given a question mark next to his name, and though he doesn't blatantly appear in the episode, his actions are alluded to the cause of Hope van Dyne's death.
  • Speaking of Whiplash, the Stark Expo was planned to be one of the following locations covered after Tony's death. This would have involved Whiplash facing off against someone else, but the whole sequence was ultimately scrapped.
