Sorta O/T, but relevant...

Since prep is often brought up in this forum and can be a crutch, given Doom's genius and typical preparedness for various situations and the frequency he draws attention to himself, who is fair to say he is already prepared for on any given day?

Even Tony Stark plans ahead and has been shown to have devices in place for telepathy and phasing. And that's NOT accounting for specialty armor.

So, who/what IYO would Doom have things built into his armor for?

Any one he considers a major player.

I remember an X-Men book from the 80s, no idea what issue, he tells Cyclops that he has defense plans capable of defeating the likes of the Hulk, Thor and Iron Man...what possible chance could a band of misfits like the X-Men have against him?

I'd say it's safe to assume he has plans for all the founding Avengers, the FF, Doctor Strange, any divine hero like Hercules or Venus, (now) the major X-Men, Spider-Man...probably groups of (in the MU continuity) growing importance like the Agents of Atlas and Young Avengers. Anyone he's tangled with in the past, including minor players like the Great Lakes Avengers and Arcade.

Probably many more. I doubt he spends his leisure time playing solitaire. Planning the defeat of potential enemies is probably his favorite hobby.

perfect, now Doom is a combination of Batman, Iron Man, Doc Strange, and Reed Richards

Instead of Hulk they should have shot Doom into deep space!
