the 2 have similar stats for the main attributes (strength speed durability) but does MM have magical invulnerability as well, or can magic affect him ?
Gender: Male Location: Drinking gasoline. Pissing napalm.
MM should win. Intangibility, phasing, and telepathy (Adam seems really, really unstable) along with nearly similar physical stats...Oh yeah! And Martian Vision.
and the shazams are supposed to be resistant to mental attacks
but your right about the phazing, I'd forgotten about that part (but what does it allow him to pass through - only normal objects or dpoes it work on superbeings like Supe or Shazam ?)
