The Nero Brothers, Zenero and Benero are members of the Tantalus Theater Troupe, unlike their brother Genero who isn't a member of Tantalus. They are humanoids, and look like hooded dogs with a twin set of claws. Zenero and Benero appear as comic relief, often having an exclamation mark at the end of their sentences, and the use of a characteristic movement whenever they talk. They reunite with their brother Genero in Alexandria when he's done with his training. They first appear in the play I Want to be Your Canary in the second boss fight with Baku. They are next seen when Baku is preparing the ship for flight. When the ship crashes into the Evil Forest they help the other crew mates. Zenero and Benero keep Steiner locked up in a room and instruct him to drink medicine to recover from a monster attack.
They also offer a minigame in Alexandria. The object of the game is to look at one of them, and then find the new location of that same brother after they change locations quickly and randomly. Minor prizes such as Cards and Gil can be obtained by winning this game.
Benero and Zenero are fought with Baku's character, King Leo, during the play.
