[Zordon's Legacy Exposed]

Zordon got rid of Jason, Zack, and Trini because they were no longer following his orders unquestionablly. Which threatened Zordon's control of the team. He wanted mindless soldiers who would carry out all his orders. So he made sure they were on the peace conference. The same thing happened with Kimberly so he made sure she left for the Pan Am Global Games. Aisha and Rocky were their own decisions. But Zordon figured he could control Tanya . Zordon had to make Justin a Ranger to make sure the other's identities weren't exposed. Either Justin would die in the mission or Zordon would keep him under control. Zordon let the Turbos go because they were getting older and would soon start thinking more independently. This is why Zordon deals primarily with teens.
