Courage the Cowardly Dog
Courage the Cowardly Dog

The Computer is the Bagge family's desktop computer residing in the attic, which Courage regularly uses to solve problems or gain information. It is an artificial intelligence (AI) that has had a large number of appearances, varying from a faithful ally (most episodes) to the main antagonist ("Mega Muriel the Magnificent"). It speaks with a British accent.


Armed with wit and a full hard drive of knowledge, it is a box of sarcasm and pride. The computer believes that lack of emotion makes machines superior to humans and finds them cowardly. However, after it experiences being in a human body, it is shown to be capable of fear despite its denial of it. When consulted with Courage's problems, it often refers to him as a "twit" and includes plenty of cynicism in its explanations.


Computer possesses a wide amount of knowledge, allowing it to give Courage the answers he seeks, but it doesn't know everything (such as how to speak to an evil shadow). It can also print out fax, instructions, pictures, and messages for Courage using a nearby printer. There is also a scanner that allows it to analysis objects and images. In "The Clutching Foot", it is able to analyse a sample of the fungus that envelopes Eustace and diagnoses a cure for it.

Computer can also connect to other machines such as a telephone, a radio in a spaceship, and Velma's tablet. In one episode, Computer gained the ability to move and transfer itself into human bodies. It took over Eustace and later Muriel, but soon went back to being a computer after a frightening experience. It is unknown if it still has these abilities afterwards.
