Arthur Dent's brother was presumably a human from Earth who was nibbled to death by an okapi long before the destruction of the Earth. Not much else is known about him aside from his unconventional death.



An okapi. One of these nibbled Arthur Dent's brother to death.

In the radio series (Fit the Sixth) he was described as being Arthur's "only brother" who "was long ago nibbled to death by an okapi." His brother and this event are not mentioned in any of the subsequent series, although in the novel Arthur thinks of his parents and sister, so, in at least one version of the story, he had both parents and a sister around at the time the Earth suddenly wasn't.
