Dawson Masterson Crenshaw, Executor of the United Legions of Defileron (November 29, 2335-January 1, 2377) was a fictional character in the Star Trek universe. Unlike most of Joshua Underwood's characters, he did not create this one; it was created for him by the former room host of the now-defunct Fragile Peace, known by his primary character, Eshi se Ranor. Crenshaw was originally created as the defense attorney for President Victor Manchester during his impeachment proceedings in December 2005/2375. He was portrayed by Robert Redford.
