Re: Lost Galaxy Rangers and the Astro Megaship Question
 

remember the Clawhammer ep? the Rangers were tied to the planet's surface, Clawhammer was about to come by to have them for his 'meal' when the Astro Megazord gets activated due to D.E.C.A and Alpha activating it even though no one was in the cockpit since Alpha was on the bridge.

Maybe they used the megazord off screen?

Zordon had it programmed for only the Space Rangers to activate by their Alphas. The Galaxy Rangers didn't have the Black Box. And Alpha was programmed not to remember the codes. Since he wasn't with the Space team anymore. This was unlocked when the Space Rangers returned. But locked again once they were gone.
