i Think i know what happened
After Rita and Zedd came Mondo and the Machine empire made a deal with the government to bring there technology on earth. I think Rocky was destroyed and made a fake evil Rocky and slowly killed the team. I think Jason and Tommy had there suspicions it was Rita all along think about it why Tommy was hiding he was slowly coming up with a plan to stop Rita i think that is were that MMPR fan film we heard about is taking place Tommy is creating new Rangers.
