FXJKHR was the President of Earth and/or President of the United States. He was apparently important enough (or egotistical enough) to be memorialized by a monument, similar to the Lincoln Memorial of the past, in Washington, D.C. - on which a savage alien sits atop a throne of human skulls. He was the first space alien to become president of the United States. Judging from the memorial statue, it seems that FXJKHR was an alien dictator that ate people.
He was president sometime between 2077 and 2141: assuming he was elected for 4 year terms, as human presidents are.
