Selene (voiced by Jane Singer) is a villainous, purple, yellow-eyed Smilodon. She first appears in "Lever in a Million Years" and has a monstrous appetite for anything that moves, including the cavepeople. According to the show's opening theme song, she and Phil were fighting on a cliff and fell when part of the cliff gave way. She landed on a lower cliff, while Phil fell into a glacier and was frozen in suspended animation for thousands of years.
