Dogbert
Dogbert is Dilbert's anthropomorphic talking pet dog from the Dilbert comic strip. According to creator Scott Adams, the character is based on, if not a member of, the beagle breed. Dogbert was originally created only so Dilbert would have someone to talk to, but as the strip progressed, Adams developed the character to be an anti-hero, metaphorically personifying the dark, cynical side of Adams's own personality. According to the strip from June 8, 1997, Dogbert even celebrates Scott Adams' birthday as his own, as Dogbert is written as being born on June 8, 1957.
Characterization
Dogbert is a megalomaniac; one of his dreams is to conquer the world and enslave all humans, and he has actually achieved this status several times through methods such as hypnosis and masquerading as a space alien or a prophet. Often, though, he quickly relinquishes his post, for instance due to boredom, someone foiling his chance, his conviction that people do not deserve to have him as leader, or his desire to go nap on a soft pillow. In both the strip and TV show he ended up the ruler of Elbonia, although he quickly relinquished the title. He has also run for President of the United States on at least two occasions as a third-party candidate, apparently losing. Dogbert appears to have sided with conservative politics, as implied during his brief tenure as a radio host. During his 2008 Presidential run, Dogbert seemed to espouse Republican political views, including a hardline on terrorism and skepticism towards global warming. Dogbert also seems to have no problem killing people.
