"You got a squeak here that would wake up Broderick Crawford."
- Brain's Father

Brain's Father is a white field mouse who appears in Pinky and the Brain. He is voiced by Ernest Borgnine.


As a regular field mouse, he has white fur, red eyes and nose, reddish-pink skin on his paws and tail, and protruding teeth. After being given Brain's pensamplivox, Brain's father becomes taller and heavier. His head is shaped very similar to his son's, and his eyes are usually half-closed. His tail, like Brain's, forms a zigzag.


Brain's father is very stubborn and a little patronizing, and often talks over his son and snaps at him to listen to him and his mother; he doesn't seem to have processed that Brain has grown since they saw him last, threatening him with time-outs and allowance cuts. While they express disappointment in Brain's "life choices," they busy themselves cleaning up his cage and fixing his wheel. He and his wife also very much like Pinky, and find him amusing. After they are sent away at the end of the episode, Brain mentions that his parents invited him and Pinky over for Thanksgiving, hinting that they care about their son, at least a bit.



The Brain's father and mother, Desiree, lived with their son in a discarded tin can in a field, decorated with an image of the planet. Unfortunately, Brain was chased and captured by scientists from Acme Labs, and his parents could only watch as he was taken away.[1]

Pinky and the Brain[]

The Brain accidentally captures his parents while attempting to grab field mice for one of his world domination plans, realizing who they are upon reading their genetic signature. He attempts to communicate with them, only to find that the lab experiments have made them unable to understand each other on any level.

He builds a pensamplivox backpack in order to give them the ability to speak, but after they were activated, his parents began scolding him and attempting to clean his cage. He isn't able to ask them any direct questions, and they seem to prefer Pinky to him. Tired of them, Brain sends them to the Everglades in Florida, though they invite him and Pinky to visit them for Thanksgiving.[2]
