2. President Superman (Earth 23)

The Strategist

Who better to strategize for our League than a dude who balanced saving the multiverse with being the friggin' president?

In this reality, Kal-El grew up as Calvin Ellis and used his big superbrain, charm, and charisma to get himself elected President of the United States of America. And he was a great president, who single-handedly saved the world numerous times. And when the Multiverse was threatened, he became the leader of Justice Incarnate, the multiverse's Justice League. It took a lot of skill to manage a team that important, and Calvin Ellis had it.

Team Role: The Strategist.

With the presidency and Justice Incarnate, Ellis was definitely too busy to actually lead this team or accompany them on their missions, but his strategic mind was a necessity. He maintained a secret identity as THE PRESIDENT. That was damned impressive. Damned impressive.
