It can be fun to mix things up, Czar, king, monarch, sultan, emperor, dictator, etc. Allow you to use different words to the same effect, and can allow alliteration. But czar is also Russian and therefore scary (even though it's just Caesar going through a game of telephone). If I were the writer, he'dbe the crown- prince of anti-corruption, getting some consonance while also quipped on the nepotis nature of his name.
