Idea #21 ^

Potential description: The evil space group, known as the Dimension Rifters, had conquered many galaxies and now had started to conquer the Milky Way.

Earth had gotten wind of this and started to create something to combat the Dimension Rifters. 5 super powered serums to give out to five trained soldiers.

Despite that, an accident occurred and four unexpected people on Earth got hit with the serum.

Now misfits have to step up and protect Earth from being conquered.

They shall be known as the Power Rangers: Freedom Flighters!
