I'm fond of Cloak and Dagger #10 [Volume 2]. The premise is Doom doesn't think the world is ready for nuclear power and decide to take it away from everyone.
Power Pack #53, a Acts of Vengeance tie-in. Doom's role is small, mostly listening to Typhoid Mary recount her encounter with the Pack. But the ending features, I think, a great character moment for Doom. A rare moment where Doom shows his love of his father. A relationship which is not touched on very often. Strange given that he knew his father much longer than his mother. There's some drama that could be mined there.
Avengers (volume 1) #332/333. Doom has a great way to sneak into the Avenger's mansion. Pre-Triumph & Torment, so he's trying to save his mom's soul. But it's done very well. Art by Paul Ryan, who does a great Doom in my opinion.
