|Lead Designer(s):||Norman Osborn|
OZ is the name of a formula that was made in an attempt by Norman Osborn to recreate the Super Soldier serum for the U.S. military.
The serum was for the most part a failure as it failed to give the people exposed to it the abilities of Captain America.
It was however, a partial success in the sense that it gave those exposed to it super powers, but usually caused extreme physical mutations.
