  • His name means "Science".
  • For now the theme listened here is "Bill Nye the Science Guy" theme remixed.
  • The fact that he has a crush on a robot makes people to think that he's a weird person.
  • He would sound nerdy, a bit annoying and mature if he had a voice. He would also sound similar to Choromatsu Matsuno [1] from Osomatsu-San [2].
