If you could be any character for one day, who would you be?

Being batman would be pretty interesting as well.

Thor - He's got the best of all possible worlds. Gets to spend time in Midgard's dimension and Asgard, and his princely duties are mainly about beating up & killing all threats to the eternal realm. Go where you want with mjolnir, able to take on any opponents up to herald level, able to drink & seduce women far beyond any possible human capacity... 😛

Even if it was just for one day, I'd go on the greatest bender of all time.

(...I guess really I would be Thor, but act like Hercules. 😄 )

Tony stark. Rich, ladies, I would test drive every suit in the Armory.

no one would want to be doctor strange?

Probably All Star Superman so that I would be able to work at light speed for 24 hours to discover a way to make my super powers last for the duration of my life.

My second choice would be Dr. Doom, so then I could go way back in time, and discover where various undiscovered treasures were buried.
