Prof. Phenomenus invents an interesting device which is able to turn just about anything good or evil. After testing it on a toy, which then attacks him, Bulk, & Skull, Ecliptor takes the so-called "Evilyzer." After Ashley & Andros check out a planet with a lot of gravity, a Quantron shoots the Evilyzer at Ashley, but hits her Galaxy Glider instead. As expected, the Galaxy Glider went nuts, trying to throw Ashley off. It's amazing what things Prof. Phenomenus can create! Anyway, Ecliptor & Astronema then agree on a plan to make the Rangers call on the Delta Megazord. After the Rangers are lured into battle & are forced to summon the assistance of the Delta Megazord, Ecliptor turns the Delta Megazord against the Rangers with a bigger Evilyzer. The Rangers eventually regain control, but at the expense of the Astro Megaship's energy supply. How the Rangers managed to destroy all of the monsters that Astronema sent down to Earth was very interesting, but what was even more interesting was that to ensure that the Delta Megazord was on the good side again, the Power Rangers joined their two megazords to form the Astro Delta Megazord. Now let's see Ecliptor & Astronema try to beat that!
