So he's actually at that level consistently?
Because this is reminding me of Magneto apparently blocking an energy beam of Power Cosmic from Galactus (though it was a starving one iirc).
Yes, Doom is at that level consistently. Remember, Reed Richards, the only person smarter than him but only JUST, was able to build a machine to go straight to Heaven to get Ben Grimm back when he died once.
Doctor Doom, meanwhile, is capable of becoming the SORCEROR SUPREME on top of his 2nd to Reed Tier Smarts. The same shit that Doctor Strange can fuck with the Multiverse as a byproduct of creating a new spell to save the day...
