Brutus and Nero

Brutus and Nero the Crocodiles are Madame Medusa's two pet crocodilians from Disney's 1977 feature film The Rescuers. They are voiced by both Candy Candido and currently Frank Welker.

The Rescuers
Brutus and Nero are in addition to giving Devil's Bayou a frightening feel, are assigned to guard the bayou, prevent Penny from escaping, and to prevent anyone who tries to rescue her from doing such, all the while knowing that Penny isn't very intimidated by them. They were animated primarily by Frank Thomas. These two crocs play various roles in the film. One of their roles is to add to the sense of gloom surrounding Devil's Bayou, and the other is to be the comic relief. They are also an obstacle for Bernard and Bianca when they try to rescue the little girl. Ultimately, they are responsible for Penny's escape, where they ended up attacking their former owner, Medusa, after she whipped them too much to go faster, and presumably killed her.

Trivia
Candy Candido's gravely voice was used for the crocs' growling, though he is uncredited it can be assumed some of their growls are recycled from Maleficent's dragon form from Sleeping Beauty. Curiously enough, Candido also voiced Captain Crocodile from Robin Hood.

They are likely based on the bloodhounds Tyrant and Torment, from Miss Bianca.

Brutus and Nero are crocodiles, they are called crocs by Miss Bianca during her, Bernard, and Penny's escape plan. It is also noted that crocodiles show both their top and bottom teeth and have V-shaped snouts. Where as alligators only show theit top teeth and have U-shaped snouts

Brutus and Nero may have also inspired the pets of several other Disney villains: Similarly, their eventual turning against their master as revenge may have also inspired the pets/henchmen of several other Disney villains: Brutus was named after the adopted son of Julius Caesar, who in the end betrayed him and Nero was named after a tyrannical Roman Emperor named Emperor Nero.
