Comments:

This episode was written by Bruce Kalish, one of the executive producers of Power Rangers S.P.D. The Black Ranger had control of the Stegazord in this episode. Although the White Ranger clone seems to use it most of the time. There seems to be a power struggle going on. It probably helps that the White Ranger clone wasn't around. I don't understand why the volcano appears to be floating in the sky. I know it's Sentai footage, but I don't think it made any sense in Abaranger either.
