So, Secret Wars #3 finally decided to reveal Doom's face after 52 years. Was this intended to show how his face always looked, or is it more scarred than it was before as a result of his battle with the Beyonders? If it's the original scars he got when his machine exploded, how does he still have them after all the times he's switched or outright recreated his body?
