James Moriarty

In the Sherlock Holmes Series, this mathematics professor is famous as Holmes' greatest and strongest rival. Despite appearing in only three works - furthermore, most of the time, he is merely mentioned by Holmes - the charisma of this evil genius nevertheless obtained tremendous endorsing thanks to the secret maneuvering during Holmes’ final case (although he would later be revived...). A genius, philosopher, thinker, and an extremely outstanding intellect. Holmes once said that he was the "Napoleon of the Criminal World" - despite being a simple mathematics professor, his organization web supposedly spread all over Europe.

According to the setting revealed within the story, he engaged in a job that was like a criminal consultant so to speak - or something.

In addition, although the Holmes Series itself is a collection of works that should be called the pioneer of every “mystery”, it could perhaps be said that Moriarty is also the fundamental being for a charismatic criminal that “plans crimes without receiving any wrongdoing for that”.

Moriarty’s public appearance is a mathematician/teacher. However, one of the treatises written by him, The Dynamics of an Asteroid, has been buried in the dark without almost ever appearing on the surface, and Isaac Asimov thought of an idea for that and wrote The Ultimate Crime, a short story in the Black Widowers Series. Also, it is highly likely that Holmes intentionally circulated misinformation to have Moriarty’s image and appearance differ from the one in the original texts.
