"Looking" star Raul Castillo has joined "Gotham" season two as Eduardo Flamingo, a character Variety describes as "one of Gotham's most dangerous hitmen" who treats murder as an art form.

Flamingo first appeared in Grant Morrison and Andy Kubert's "Batman" #666. In the comics, he is an emotionless killer who eats his victim's faces after he murders them. A master assassin, he's proficient in all kinds of firearms but prefers a spiked chain. In "Gotham," he'll quickly prove himself to be a tricky foe for Jim Gordon (Ben McKenzie).

Castillo's past credits also include "Special Correspondents," "Staring in the Sun" and "Sweets."

Starring McKenzie, Donal Logue and David Mazouz, "Gotham" airs Mondays at 8 pm EST on Fox.
