Secret Wars, Chapter 3: Doom - S5-E11
Continuity mistake: After the Beyonder ends the war, he teleports everyone to a floating chess board in space, with Dr. Doom lying near the edge. When the shot changes, Doom has moved closer to the middle of the board. He is unconscious so he couldn't have moved.





Answer: I believe it was just a way to try and show the suit is "oily" or reflective. It also helps define the character's features since otherwise, he'd just be a flat black color. It's similar to how the black suit Spidey had blue outlines. (I don't know why they chose a pink/red color... maybe because red is associated with power/fire/war, so it's a more "evil" color?)
