The network picked up a serial killer drama from Vampire Diaries executive producer Kevin Williamson, as well as a legal show from Greg Berlanti and Marc Guggenheim.
In addition, Fox has ordered comedy Ben Fox Is My Manny, Deadline reports.
Williamson's project is currently untitled, but it centers on a serial killer who uses technology to establish a cult of killers.
The series from Brothers and Sisters bosses Berlanti and Guggenheim is titled Guilty, and follows a defence attorney who is stripped of his license when he is falsely accused of fraud.
What Happens in Vegas writer Dana Fox's comedy series Ben Fox Is My Manny focuses on a single mother whose brother moves in with her to help raise her child. The male lead is based on her real-life brother, who is also named Ben Fox.
It was first reported that Williamson had sold a pilot to Fox in September.
