All in the Family: Highfather and Uncle Sam Bend Time and Space to Keep the Peace
Two centuries ago a hero was born in the form of Sam aka Uncle Sam. Defending the western land from threats at home and abroad, this Sam eventually needed to pass on his superhuman abilities to another man, also named Samuel just prior to World War II. The original Sam found his cosmic twin in the form of Izaya who as the Highfather of the planet New Genesis, guided his people through various wars with neighboring Apokolips. Guided by an unknown entity known as the Source, Izaya also has vast superhuman powers.
Using his perception of time and space, Uncle Sam was able to see danger on the horizon of a parallel world to his own, Earth-X... which had no heroes of its own. Over a period of a year, Sam would recruit three different groups of costumed crusaders to join him in saving this new world, secure in the knowledge that his own planet was well protected by its assembled might of the All-Star Squadron. These Freedom Fighters would remain together for decades, battling Nazi oppression.
Using his perception of time and space, Highfather led his so-called New Gods of the floating Supertown in the extra-dimensional realm where his world and that of planet Apokolips resided. Despite several incursions and manipulations from his rival on the latter world, that being the evil Darkseid, Izaya was able to maintain a tenuous peace that sometimes broached conflict on the adjacent Earth-One, where both his and Darkseid's forces at times resided.
