T-Rex (Planet of Dinosaurs)

The Tyrannosaurus Rex is the primary antagonist in the 1978 sci-fi film Planet of Dinosaurs. He lives on an unknown planet where dinosaurs roam.

He first appeared when the humans encounter him. They run off and the Tyrannosaurus fights a Stegosaurus and kills it after a brief fight.

It later appeared attacking the humans at night and killing Derna when she tries to get the laser to fight off the giant. Her death prompts the group to try to kill the T-Rex.

They first try to poison him by smearing poisonous berries on a dead Polacanthus for the T-Rex to eat. The plan backfires when the T-Rex shows up behind the group and kills Mike.

Jim then comes up with the idea to impale the T-Rex on several wooden stakes. The T-Rex, after killing a Rhedosaur, chases the group and ends up falling on the stakes, killing him and nearly falls on Jim as well.
