Napoleon is widely described as either a demigod or a demon / devil, though, as Danila Smirnov mentioned, not immortal. Might you be misremembering this, or perhaps something like it:
Napoleon . . . [is] sometimes cast as a demigod, sometimes as a demon, practically always seen as a figure considerably larger than life. Probably no other mortal has received so much attention from historians and biographers, critics and enthusiasts.

The "no other mortal" phrase that followed could well have caused a confusion in the memory.
On the note of angels; it's a different Napoleon, but Samuel Schmucker offered this formulation:
Louis Napoleon is neither on the one hand an idiot or a demon; nor is he on the other a demigod or an angel.
