Dr Doom w/IG vs Beyonder

Scenario:

Dr Doom wields the Infinity Gauntlet; The Beyonder is busy tryingto figure out humanity. Dr Doom get prep time to siphon the beyonders powers or whatever he wants for like a couple days. He also has the IG to protect himself against the beyonder if need be.

What Happens-

In terms of power Beyonder in his pre retcon form is still greater however Doom was able to siphon his powers before with prep and just Galactus' might. Its certainly a possibility.

Doom curbstomps the Beyonder

with prep time doom can do alot of things because he is doom and prep time+doom=the person their fighting is f*cked. add the infinity gauntlet i think he has a pretty good chance of atleast stalemating beyonder and possibly even beating him.

If this is pre-rec beyonder ---- Beyonder wins

if it's the cube beyonder ------- Doom wins easily
