this isn't a versus match. Magneto solo'd a team of X-men; the Phoenix included. he did it with a combination of skill and inherent power. Galactus is a jobber. Doom "beating" the Beyonders is just proof that so-called powerful beings can be caught with their pants down. Doom didn't just walk up and challenge them to a fight. it took a ludicrous amount of prep work. if you want to take it down to a versus fight, put them in a room. neither guy gets to use armor. just genetics vs genetics. Doom gets eviscerated.
