Doom has, in no particular order, absorbed the likes of Galactus, Nightmare and the Silver Surfer, the latter of which could resist such things coming from Mephisto. He can teleport to anywhere he thinks of, swap bodies with people, hack into Reed Richard’s technology, blast Morgan Le Fay back through time to 1 million BC, remove the fantastic fours powers, go back in time to the point of doing it over and over again until he could win, reverse time, distort peoples perception by shooting them a few seconds back in time, his armour adapts and has its own will and can turn invisible, he can transmutate matter into energy, scramble your brain so that you cannot use your strength, inject toxins into people with a touch, shatter the cohesion of someones molecular structure, rearrange peoples bodies into a state of disorganisation, has an antimatter gun, make illusions of himself, manipulated doctor strange’s soul and has repelled the very laws of physics. He knows magics that even Doctor Strange doesn’t and is stated by Scarlet Witch to have more power than her and Strange, and this is the scarlet fucking witch we’re talking about here, he has a machine that literally can control the experiences of peoples fucking lives. He can turn off the penance stare, he can fucking tank blasts from Morgana Le Fay who ERASED THE SENTRY FROM EXISTENCE. Hell he can just summon an army of Mindless Ones to do his fighting for him. Even without his powers, he could beat taskmaster in a direct fight, without magic, what the fuck. Oh and not just that, Doom has mindhaxxed and trapped Rachel Summers as the phoenix in his own kind of mental omega sanction. This fucker once absorbed the odinforce from a lightning bolt fired by Thor and made his own destroyer armour out of it.
