The holiday season will never be the same. Based on the extremely graphic novel by Grant Morrison and Darick Robertson, Happy! premieres December 6 on Syfy.

The series follows Nick Sax – an intoxicated, corrupt ex-cop turned hit man – who is adrift in a world of casual murder, soulless sex and betrayal. After a hit gone wrong, his inebriated life is forever changed by a tiny, relentlessly positive, imaginary blue winged horse named Happy.

Happy! stars Christopher Meloni, Patton Oswalt, Lili Mirojnick, and Bryce Lorenzo.
