Futurama Episodes

Fry is put on trial for his life for traveling to the forbidden planet of Omega 3 to retrieve all 79 episodes of “Star Trek”, and he must defend the claim that human kind needs “Star Trek” to give them hope for the future. In the 23rd Century, “Star Trek” fans had evolved to such a level that they corrupted the world’s governments and all things “Star Trek” were then banned to Omega 3. Fry sets out on his mission with Leela, Bender and Leonard Nimoy’s head in a jar, only to discover William Shatner, Nichelle Nichols, George Takei and Walter Koening are living on Omega 3 under the watchful eye of Melllvar, an evil energy creature — and “Star Trek’s” biggest fan.
