While not encompassing all the updates I have for Doom, I thought I'd post these as well:
SORCERY
Doom's expertise permits him to (i) detect the considerable cloaking magicks of the Hood, and (ii) predict in advance, the teleportation of a god, from Secret Invasion: Dark Reign #1:
Doom's appearance in Dark Avengers also revealed quite a bit about his sorcery: (i) although ambushed by a prepped Morgana Le Fay, Dr. Doom is able to briefly hold his own for a time; (ii) apparently, Dr. Doom can use time travel with not just his machines, but his magic too when he banishes Morgana Le Fay to prehistoric ages; and (iii) transference spells capable of turning a god into stone are "simple" ones and easily reversed by Doom, from Dark Avengers #2 and 4:
Here, Doom manages to draw in and teleport Meggan out of Hell (who had just led an uprising throughout Hell itself), from Captain Britain and MI13 Annual #1:
While it may appear self-evident, it's now clear that Doom's armor protects him from telepathic probing from even a telepath of Emma Frost's level, from Secret Invasion: Dark Reign #1:
And well, Doom has a built-in Time Cube. Which not only permits him to travel through time, but allows him to reverse time in localized areas, from Dark Avengers #4:
This is pretty neat. Doom actually incorporated splinters of the "true cross" to ward off evil, like Dracula, Lord of the Vampires, from Captain Britain and MI13 #11:
Doom's fight with Doctor Voodoo revealed a few things: (i) he can teleport, (ii) he's got an Ectoplasmic Ionizer that discorporates ghosts, and (iii) he can literally seize control over magical teleportation energies, from Doctor Voodoo: Avenger of the Supernatural #1:
^ Personally, I've never subscribed to the idea that two feats must be mutually exclusively from each other.
I've never felt the need to reconcile the two feats but for your curiousity, offhandedly, I'd say that in Secret Wars, Galactus bore the main brunt of the Beyonder's attack and Doom was luckily subjected only to the aftershock, whereas in Mighty Avengers, Sentry clearly has one of his redeeming uber-moments, ala curbstomping Terrax, overloading Absorbing Man, etc.
In this update, I'd thought I'd showcase some of the more physical characteristics of Doom's actual armor a bit more:
BLAST POWER
While somewhat of a non-feat because Thing was previously injured, it's still impressive that Thing gets completely wrecked by only three of Doom's handblasts, from Fantastic Four #361:
Black Panthers advanced vibranium suit does not save him from being one-shotted and nearly killed by another handblast, from Black Panther vol.5 #2:
FORCE-FIELDS
Although Blastaar's power is magnified in the Negative Zone (he has lierally disintegrated Sersi in one shot once), Dr. Doom's forcefields are able to withstand his barrages, from Fantastic Four #318:
ARMOR'S DURABILITY
There aren't a lot of pure armor feats since Doom is rarely stripped of his forcefield, but I've neglected to add in a few obvious instances where he eschews the use of his force-field and completely relies on his armor. So I'm going to post a bunch to help illustrate the extent of his armor's durability. Here, the Human Torch's flames have literally no effect on his armor... heck, they don't even singe his cape. From Fantastic Four #318:
While it doesn't appear apropos for a respect thread since Doom is getting mightily pummeled, this is one of his armor's more impressive blunt force durability feats. Keep in mind, Namor's famously ripped Ironman's armor apart like it was paper underwater a couple of times. Here, Doom's getting straight up blitzed by a bloodlusted Namor underwater AND another Atlantean. I think that just surviving the barrage despite the doubling and redoubling of the blitz is quite impressive, from Namor vol.2 #31:
But for those who aren't impressed by Doom getting wrecked, here's another pure blunt-force armor durability feat, Doom barely registers a straight haymaker from the Thing, from Fantastic Four #537:
And Storm's point-blank lightning strike has no effect on Doom's armor whatsoever, from Black Panther vol.4 #19:
^ Hmmm. I assumed his standard suit contained vibranium. I always considered T'Challa to be a prepare-for-anything at-any-moment type of guy. After all, why wouldn't he use vibranium in all his suits? Wakanda's rich with it. But then again, it may not be true. I'll have to re-read to see if it's mentioned at all.
In the meantime, here's an old one-on-one fight with Human Torch that I never uploaded. Don't know why, maybe because I thought it was too short. Because basically, Johnny gets curbstomped by Doom.
^ On review, I saw nothing that suggested Black Panther was prepared to take on Doom. Truly, a case of PIS. Because T'Challa and Doom both agree on how he would never agree to be recruited by Doom. And yet he shows up without his best suit? Stupid. For plot's sake. Which is what PIS is.
I've read Black Panther vol. 4 once through, and I don't remember any specific instance where he said he did, or didn't have, a vibranium enhanced suit as his base normal suit. Frankly, despite T'Challa's character of constant preparedness, unless someone has proof all his suits have vibranium lacing, than it's just a case of PIS on his part.
