Power Rangers: Rebirth

Five years ago, the Power Rangers from every generation fought against a massive invasion force known as the Malastarians. The armies of the world fought alongside them and in the end they were victorious. Unfortunately, the price was too high and so many rangers died in combat and very few are left alive with only enough power for one last morph. Five years later, five young people are chosen by entities of the zodiac to fight against the returning Malastarians, and the old Rangers will mentor them for what is about to come.
