Victor Frankenstein - Frankenstein; or the Modern Prometheus
The story of Frankenstein alone is enough to make me feral, but oh God, Victor is a character who haunts my psyche. The progenitor to the modern mad scientist trope, of course I love him. He's my name sake, as well as the basis for at least half of my original characters. A man brought down by his own hubris and intellect, someone who desires to work from death to create life, of course he is someone I'd immediately be obsessed with. The story of Frankenstein is a classic for a reason, and reading the book in 10th grade changed my life.
