ok tony has an hour to prep and he has 3 people to help him bulid an armour
dr strange ( for he can give the armour magical properties)
mr fantastic ( great mind and scientist)
forge (he can build nearly anything anyone tells him)
Very very vague, we dont know how powerful the armour is so we cant compare it with sentry nice idea though...should of gave the armour some power lvls or something
We actually don't know how powerful Galactus was at the time, since we've never seen the fight. It's very possible he could have been on the verge of starving to death.
I'm just using the comics that I've read about him. I don't have the one with Sentry and Galactus but I was under the impression that Galactus was very hungry in that comic. Anyway, Sentry still is a question with me regarding his powers. If you have info or scans that would change my decision, please post them.
I think Sentry would still wn because in his own book his other side I.E. the Void almost destoyed the world and even with a sheild mad of and powerd by Iron Man, Invisible Woman, Dr. Strange, was almost less than useless compaired to his power.
