With Robert Downey Jr. proclaiming "New mask, same task" when he was revealed as the MCU's Doctor Doom, and Anthony Mackie stating that he is "continuing" his legacy, this feeds into the notion that Doctor Doom will be directly tied to the MCU's Iron Man.

Anthony Mackie says Robert Downey Jr.’s return as Doctor Doom continues the legacy Iron Man built in the MCU. Robert Downey Jr.’s return to the Marvel Cinematic Universe has been confirmed, but not as Iron Man—this time, he’s stepping into the villainous role of Doctor Doom in Avengers: Doomsday.

According to a new report, Marvel Studios is mulling over whether to keep Robert Downey Jr. as the MCU's Doctor Doom after Avengers: Secret Wars. We also have updates on Ghost Rider and the Blade movie.
