- After the events of the Secret Wars 2015, Doom encountered Tony Stark in the ruins of Doom's once lavish palace. To prove his identity to him, he recounted to him the time that they had been sent back in time to the days of King Arthur to have a rousing adventure together. Doom told Stark that he always looked back on that time fondly. Stark did not share his zeal for that moment, still upset that Doom attempted to kill him and strand him there. Doom then reiterated to him that he remembered it fondly, but never said that Stark did.
- A while ago, Doom was aboard a ship with Spider-Man, who made a reference to Star Trek: The Original Series, albeit an erroneous one, as he said "Warp factor 9, Mr. Spock." Doom corrected him by reminding him that it was Sulu, not Spock, who set the speed of the U.S.S. Enterprise in the series. Spider-Man mocked Doom for being such a "nerd."
- Captain America once asked how Doom is capable of "speaking your name all in capital letters." The answer was simple. "I. Am. DOOM."
