Richard Trenton Chase, a.k.a. "The Vampire of Sacramento", was a schizophrenic "vampirist"-type cannibalistic and necrophilic, family annihilator, one-time enucleator and serial killer/spree killer who was active in California from December 1977 to January 1978. He was brought back by Zero. Allegedly abused by his mother while growing up, Chase had already fulfilled the MacDonald triad (bed wetting, animal torture, and fire-setting) by the age of 10. In adolescence, he was already an alcoholic and chronic drug addict; Chase also had erectile dysfunction. When an adult, he became a hypochondriac, eventually moving out of his mother's home because he believed she was trying to poison him. He was resurrected in 2024 and became a part of ISG.
