My idea/pitch for the reboot...

The series BEGINS in 1993 with humanity establishing first contact with a race called "The Eltarians" and through a quick montage we see society progressing to 30 years later to our modern day with Earth's population now a mix of humans and aliens.. but some things never change...

Despite warnings from Eltarains that mining in a certain area outside of Angel Grove is dangerous, a greedy corporation does it anyways, beliving the Eltarians are hiding something valuable there...and unleashing a long buried evil in the process... Lord Zedd and his wife Rita Repulsa are unleashed when the mining uncovers their chamber. The Eltarians are alerted to Zedd and Rita's escape when they begin attacking the town.

The Eltarians admit that this is not their first time on Earth and that in the Cenozoic Era they fought and barely defeated Zedd and Rita back then, only by the sacrifice one of their best named Zordon..

The Eltarians reveal they have a plan to combat Zedd and Rita's force.. a group of superpowered warriors whose name loosely translates to "Power Rangers". The eltarians dispatch the morphers to seek out those who are worthy of wielding these powers despite objections by the Government and the Military.. 5 new rangers are chosen and brought to the Eltarians and instructed by a still-alive Zordon.
