ah I see... anyway I do agree that just because Zordon's wave destroyed the evil that doesn't mean it destroyed all of the evil. It was left vague for a reason all he simply said his energy would destroy the "forces of evil" yet it's a vague term that was stated in case Power Rangers was brought back with a new season and almost all villains can be excused away from escaping Zordon's energy wave.

Galaxy = Scorpius, Trakeena and Mutiny were all in another universe far from Zordon's wave.

Lightspeed = Demons were still sealed.
Time Force = Ransik wasn't born yet.
Wild Force = Orgs were still sealed.
Ninja Storm = Lothor likely wasn't a truly evil person... yet.

Mystic Force = They were still sealed.
Overdrive = Flurious and Moltor were still sealed.
Jungle Fury = Dai-Shi and the others were still sealed.
RPM = In another dimension.
Samurai = The Nighlok were still sealed.
Megaforce =
