The clone of Superman was Superman with a 90s attitude, basically if the Image guys created Superman. Young, brash, trendy haircut and a leather jacket instead of a cape. Oh, and he had belts everywhere.
John Henry Irons was trapped under a building during the Doomsday Massacre. Upon realizing that Superman is dead, he seeks to carry on his legacy in a suit of literal steel and protects Suicide Slum, a neglected neighborhood in Metropolis. Suicide Slum is overrun with gangs brandishing highly power “Toastmasters,” guns that Irons himself help develop. Now he’s committed to taking them off the streets!
