Yarael Poof

Yarael Poof is a Jedi Master in The Phantom Menace, but he was treated rather poorly by the filmmakers.  Wookieepedia explains.

Yarael Poof first appeared in the 1999 film Star Wars: Episode I The Phantom Menace, in which he was portrayed by a puppet operated by Michelle Taylor. Although his name was never spoken in The Phantom Menace, it was given in the film's credits.[4] Poof was originally slated to reappear in Star Wars: Episode II Attack of the Clones, but George Lucas was concerned that viewers would confuse him with the Kaminoans, a new species introduced in the film. As no new footage of the Jedi Council chambers were shot for Episode II, archive footage from Episode I was reused. In order to remove him from the film, Poof was digitally painted out of the footage and replaced by Coleman Trebor, a new Jedi Master designed for the movie.[13]

Yarael Poof gets no respect. Which turns out to be a good thing for him, as you can see in this Adult Swim sequence. (via Geeks Are Sexy)
