Who is the masked mystery man known only as Twilight? And what does he have to do with one particular purple pony princess?

Return with us now to the days of ten-cent comics on cheap newsprint, of four-color fantasy that stayed around a lot longer than anyone expected it to. Princess Twilight Sparkle finds herself taking the place of a human, also called Twilight. The time may be different, the setting may be different, but evil stays the same.
