Beyond both Victor and Tony being uber-geniuses who invented and wear incredibly powerful armour, there's not much direct connection. In fact, Doom invented his mask and suit while studying in a hidden monastry with Tibetan Monks. And since Dr Doom debuted a few months before Iron Man, it means he was actually the first to build Powered Armour,
"In a cave! From a box of scraps!"
Victor did try to redeem himself by taking Tony Stark's place and becoming the Infamous Iron Man at one point.
Amusingly, Doom is possibly the only Marvel character even more arrogant than Tony Stark, although given his incredible skills, powers and victories, his massive ego is somewhat justified. Tony can at least match Doom in Robotics and associated fields, but he has next to no knowledge of Magic, while Doom is second only to Dr Strange in that field.
And while Tony is a decent fighter at best without his Suit, Doom is a Master of the Martial Arts. At one point a ridiculously powerful enemy strips Doom naked and transports him millions of years into the past. Doom is attacked by a Prehistoric, "Lion". Victor kills it with a single punch from his bare hand. Then eats it, and uses the hide, bones etc to make a primitive version of his mask and armour.
Doom is what you get when you take Batman With Prep Time as your baseline for a character. And then Turn the Knobs up to 11.
That's precisely why I fancast Matthew Macfadyen as Doctor Doom back in 2012 because of his intimidating voice (not to mention he's a terrific actor). Unfortunately that option is now out since he's playing a different character in Deadpool & Wolverine.
Eh, he also regularly loses to a Stretch Armstrong and a dude made of rocks.
I would cast JJ Feild if they're looking for a late 40s or early 50s Doom.
On the flip side, Hans Gruber, Darth Vader, Hannibal Lecter, T-800, T-1000, Anton Chigurh, Hans Landa and many more villains did not need multiple movies to set them up.
That Avengers comic is one of the reasons I'm a big fan of the Absorbing Man. I also had that Alpha Flight comic.
Feild looks so familiar, yet the only thing i’ve seen him in is the first Captain America movie, which i’ve only seen once. since watching Femme, George McKay has solidified his spot as my #1 fancasting choice for a Doom if they want to try to pull it off w/ a late 30s/early 40s actor once we get there. only issue might be how youthful he looks, & will probably still look in 5ish+ years, but that’s nothing a Doom mask can’t fix lol
I became a fan of JJ Feild after watching his terrific performance in Turn: Washington's Spies (underrated show which everyone should check out). He also could replace Tom Hiddleston as Loki.
Charles Dance is also my top choice as Doom back in 2012. It was either him or Macfadyen for Doom. Eventually I settled with Dance as Galactus since I needed my Doom to sorta match Reed's age since they were college roommates.
