Dr.Doom w/prep vs Pre-crisis Superman

Doom would need about 100 seconds prep to kill Pre Crisis Superman, 1 year of time to prepare is overkill

With that much prep time doom steals Superman's powers.

Then Clark just becomes a normal man and doom decapitates him like a boss.

Doom shouldn't have much of an issue with a year of prep.

He's defeated more with less. Before the year is up doom would probably amass the IG and a cosmic cube and blink SA superman. He wouldn't even have a need for his powers at that point.

1 year of prep is way more than enough time for Doom to figure out a way to steal his powers.

That much prep is overkill. Doom stomps.
