The unseen threat that forced Jake (Andy Samberg) and Holt (Andre Braugher) to go into the Witness Protection Program will be seen this season!

Brooklyn Nine-Nine has cast menacing mob boss Jimmy "The Butcher" Figgis for Season 4. Eric Roberts, who starred in Less Than Perfect and recurred on Heroes, will play Figgis and be heard before he's actually seen, according to Entertainment Weekly. We'll get our first look at Roberts in the third episode when he actually makes a physical appearance, but Roberts will get a voice cameo in the episode before.

Get ready for the New Girl/Brooklyn Nine-Nine crossover event

Roberts is the brother of Julia Roberts and father of Scream Queens star Emma Roberts. He was nominated for an Academy Award for his work in 1985's Runaway Train, and has had an eclectic career since, appearing in Doctor Who, The L Word, Crash and much more.

Brooklyn Nine-Nine returns for Season 4 on Tuesday, Sept. 20 at 8/7c on Fox.
