An odd choice for a Halloween pic, you might ask?
Nope, Zoom terrified me during season 2 of the Flash on CW.
Hunter Zoloman is his name. In the TV series, as a kid, he saw his father kill his mother. He went to an orphanage (No living relatives wanted him). So years down the line, he became a serial killer. Earth-2's most notorious. Criminally insane and became the recipient for electro-shock therapy for his bloodlust. Then, Earth-2's particle accelerator blew up and gave him his speed. Became a villain, got bored. Became a hero, got bored again. So after discovering alternate Earths and enhancing his speed with drugs that's starting to kill him, he took to looking for more speed.
Abducted Earth-3's Jay Garrick and set about trying to kill Barry Allen and steal his speed.
The guy made disposable time remnants (2 that are known, One calling himself Jay Garrick and another Zoom as fodder).

I'm kind of glad he's 'dead'. But I miss the guy's bone chilling character. The guy's completely mad and evil. But I'll miss Zoom and the voice! Oh the voice! Tony Todd of Candyman! Perfect match!
