Ryymax

From Muppet Wiki

In the Farscape episode "I, E.T.", Commander Ryymax is the military officer thats are in charge of investigating the U.E.O. sighting, that could very well be a ship that entered the planets atmosphere.

He arrives to question Lyneea and Fostro about the possibility of aliens landing on the planet. His crew ends up capturing D'Argo, and wants to hold him so they can perform a autopsy on him later. Lyneea sends Ryymax on a wild goose chase, by showing him a video conversation that John Crichton had with Pilot earlier, and saying that the transmission came from Akon's Field and not the nearby swamp were Moya really is located. This allowed Crichton to rescue D'Argo and escape to Moya.
