Professor Phenomenus is a scientist who specializes in alien searching. He replaces Mr. Caplan and Jerome Stone as Bulk and Skull's linking character for two seasons. Unlike the former characters who were strict, Phenomenus had a very wacky, scatterbrained personality and a very sweet nature. As a result, Bulk and Skull went through a role-reversal as they became the straight men to his wacky antics.
After Bulk and Skull observe Astronema's Dark Fortress through a telescope one night, they come to Phenomenus for help. Phenomenus believes anything harmless can be an alien in disguise. He says it looks normal "to the untrained eye". Phenomenus, along with Bulk, Skull, and other civilians of Angel Grove, claimed to be the Power Rangers to Astronema in the season finale. He claimed to be the Red Ranger.
Phenomenus, Bulk, and Skull were to board the space colony Terra Venture in its voyage to the New World. However, Skull overslept thus only Phenomenus and Bulk got aboard, not remembering Skull until they got on Terra Venture. In the episode "Stolen Beauty", it was revealed that the two were "booted" from the GSA's science division and worked as bartenders at the Comet Cafe. They appeared again in the season finale sometime after the cafe was destroyed.
