Viktor himself states that he is a professional slime rancher, slime scientist and amateur musician. His speech pattern indicates that he is an intellectual, further backing up his profession. He has a keen interest in the slimes that inhabit the Far, Far Range but his studies prevent him from exploring, so he makes requests for various slime species on the Range Exchange.
He loses his fiddle sometime before the events of the game and specifically requests for it returned to him if found, but there is currently no way to find it or return it to him.
The Loading Screen Texts imply that Viktor suggested creating cube-shaped Slimes, and that he invented a plort-cloning technology, but ultimately ended up destroying it.
- "Django's Tiger" in the Range Exchange dialogue refers to Django Reinhardt's song of the same name.
- "Cube-shaped Slimes" refers to the Gelatinous cube, and every cube shaped slime monster in fantasy settings inspired by it.
