DC Comics has announced War of the Supermen, "an event that is sure to change Superman's status quo" for 2010.
DC unveiled J.G. Jones' cover for War of the Supermen #0, which will be available on Free Comic Book Day on May 1.
According to DC, writer James Robinson and artist Eddy Barrows are "taking point" on the issue.
Said editor Matt Idelson: "War of the Supermen is the culmination of literally years of stories in the Super-books, all building to a destructive conflict which can have no victors. This Free Comic Book Day #0 issue is going to show the readers that no cows are sacred, and that they don't want to miss this event."
