  • According to Welt Joyce, he said that Lieserl Albert Einstein is 4 years older than him
  • His name "Welt" is come from Lieserl Albert Einstein because Ω1 doesn't remember his real name. Ω = W, Welt (German) = World
  • He can speak German, English, Russian, Latin,... both Japanese and Chinese too. Probably due to the 1st Herrscher power inside him.
  • On 21/10/1950, he got his fake family name "Joyce" from Einstein (on his passport). This is a reference to James Joyce, the author of Ulysses.
  • In the Anti-Entropy visual novel, you could see Welt recalling a lot references from many literary works, especially Divine Comedy (written by Dante). This was because during his 3 years of being experimented, Otto gave him a lot of books to read.
  • He died from an injury and gave his Herrscher core and the name "Welt" to Welt Yang.
