During Power Ranger in Space, Astronema created the Psycho Rangers to drain the power of Dark Specter so she could take over as monarch of evil. Each Psycho Ranger was obsessed with defeating the Ranger of their colour and each used a weapon similar to their Ranger. They were defeated but later came back with the use of a digitizer and were digitized into cards at the end of that episode. They would again return in Power Rangers Lost Galaxy as the reason for the first ranger team crossover episode.

Psycho Blue uses an axe and was an ice like monster in his true form.
