Venomous quillcat is a demonic result of genetic experiments and black magic. Beware! He likes to hug people and pets, but his toxic fur and quills are covered with a strong poison that causes enhancement of the victim's artistry and critical thinking.

He was physicist Dimitri, who worked in a secret laboratory located in the Kola Superdeep Borehole. The main goal of his department was gaining an essence of cuteness. But after an unsuccessful experiment with kitten's fur, echidna's quills and Necronomicon his body and mind mutated. He was captured and subjected to research, but escaped from the hell laboratory, and now he lives in the wilderness.

He took a new name — Demphys, which means "demonic physicist".
