After Power Rangers in Space (1998), Jason Narvy, Skull, decided to go back to school. So they wrote him out of the series. That's why he only appeared in the first episode.
This is the only series in Power Rangers where a former villain from a previous segment becomes a Ranger.
The Ranger suits for this season have been nicknamed "The Charlie Brown Costumes" because of the signature squiggly, pointed black line across the torso and around the cuffs of the boots and gloves.
Reggie Rolle (Damon Henderson) and Amy Miller (Trakeena) fell in love during filming and later married. They would later divorce.
